F rom its inception as a brief journal article in 1929, the Publication Manual of the American Psychological Association has been designed to advance scholar- ship by setting sound and rigorous standards for scientific communication. The

creators of the 1929 manuscript included psychologists, anthropologists, and business managers who convened under the sponsorship of the National Research Council. They sought to establish a simple set of procedures, or style rules, that would codify the many components of scientific writing to increase the ease of reading comprehen- sion. This goal was subsequently embraced not only by psychologists but also by schol- ars in other social and behavioral sciences who wished to enhance the dissemination of knowledge in their respective fields.

Uniform style helps us to cull articles quickly for key points and findings. Rules of style in scientific writing encourage full disclosure of essential information and allow us to dispense with minor distractions. Style helps us express the key elements of quan- titative results, choose the graphic form that will best suit our analyses, report critical details of our research protocol, and describe individuals with accuracy and respect. It removes the distraction of puzzling over the correct punctuation for a reference or the proper form for numbers in text. Those elements are codified in the rules we follow for clear communication, allowing us to focus our intellectual energy on the substance of our research.

Today, Style sets a standard that is realized in APA journals, books, and electron- ic databases. In my tenure as APA publisher, the APA Journals program has grown from one that publishes 17,700 pages a year to one that publishes 37,000 pages a year. The APA Books program has grown from 12 books to over 1,214 books as well as 160 psychother- apy training videos. APA electronic products have grown from one database to five data- bases that offer users immediate connection to abstracts, books, journals, reviews, and quality gray literature. This profusion of scholarship has been supported and defined by the guidance provided in the Publication Manual. Together with the APA Dictionary of

Foreword

FOREWORD 4

Psychology and Encyclopedia of Psychology, it establishes a sound foundation for the advancement of the field.

The Publication Manual is consulted not only by psychologists but also by stu- dents and researchers in education, social work, nursing, business, and many other behavioral and social sciences. Its standards are available in English as well as Spanish, Portuguese, Korean, Chinese, and many other languages. A central focus of delibera- tion for this edition has been the way in which web-based technological innovations have altered the way we conceptualize, conduct, and consume scientific research. The sixth edition of the Publication Manual is devoted in large part to interpreting these advances and incorporating them into the style lexicon, It is my hope that, in concert with our other reference products, it will serve as a solid base for all of your scientific communications.

rfo better understand the complex changes in scientific publishing and address

them in this edition, many experts and professional groups were consulted. We began the revision process in 2006 by looking closely at the fifth edition, ana-

lyzing more than five years of accumulated user feedback; evaluating published criti- cism; and commissioning reviews from senior editors in psychology, education, nurs- ing, history, and business. After deliberation of and debate about these comments, the APA Publications and Communications Board set broad parameters for the revision and appointed a panel of experienced editors and scientists from diverse specialty areas to collaborate with dedicated staff on the revision.

The six-member Publication Manual Revision Task Force met for the first time in February 2007. They determined that revisions were needed in seven key areas: ethics, journal article reporting standards, reducing bias in language, graphics, writing style, references, and statistics. Working groups of experts were established to support the work of the task force in each area.

As the revision progressed, APA staff continued to solicit recommendations for revision from the APA Council of Editors, from Publication Manual users at the www.apastyle.org website, from APA members at professional meetings, and from APA boards and committees. Those recommendations were passed along to working group and task force members for consideration.

Thus, this edition of the Publication Manual is the result of creative collaboration with many groups and individuals. We must first thank the members of the Publication Manual Revision Task Force. They devoted many hours to analyzing reviews, consid- ering the scholarly publishing climate, identifying topics in need of greater coverage, meeting with working group members to generate and revise text, critiquing and dis- cussing new drafts, and poring over the final draft with a persistent commitment to getting it right. We are fortunate to have benefited so thoroughly from their enthusias- tic and generous support of this project.

PREFACE

We are also grateful for the contributions that came from the working groups of experts who helped shape this edition. They dialed in faithfully to join Webex confer- ence calls, collaborating to ensure accurate and comprehensive coverage for their respective areas. We benefited from the welcome blend of tact, humor, and insight that they brought to this project.

Early in the revision process, we solicited critiques from selected core users, that is, from senior editors and writers in the areas of psychology, nursing, education, and business. The overall recommendations gained from those individuals greatly influ- enced the approach taken in planning this edition of the Publication Manual. For shar- ing their insights and suggestions, we thank Barney Beins, Geoff Cumming, Janet Shibley Hyde, Judy Nemes, Kathryn Riley, Henry Roediger III, Peter W. Schroth, Martha Storandt, and Sandra P. Thomas. On a related note, we are indebted to Linda Beebe and the PsycINFO staff for their invaluable guidance on how evolving technolo- gies continue to affect the reading, storage, and retrieval of scholarly work.

To guide us in our commitment to provide sound and timely instruction on scien- tific reporting, we solicited comments from several APA boards and committees. We are grateful for recommendations received from the APA Committee on Ethnic Minority Affairs; the APA Board of Scientific Affairs; the APA History Oversight Committee; the APA Committee on Disability Issues in Psychology; the American Psychological Association of Graduate Students; the APA Task Force on Gender Identity, Gender Variance, and Intersex Conditions; and the APA Committee on Socioeconomic Status.

Several writing instructors and coaches contacted us with suggestions for making APA Style more accessible for students. For taking the time to share their recommen- dations, we are most grateful to Dee Seligman, Wendy Packman, Scott Hines, Geeta Patangay, Mylea Charvat, and Jeff Zuckerman.

Last, we thank the APA Office of Publications and Databases staff for their many contributions to this edition, including Paige Jackson, Susan Herman, Annie Hill, Harriet Kaplan, Edward Porter, Shenyun Wu, Amy Pearson, Ron Teeter, Hal Warren, Beverly Jamison, Susan Harris, and Julia Frank-McNeil. Nora Kisch, Julianne Rovesti, Peter Gaviorno, and the entire sales and marketing team have worked tirelessly to inform the broad social science community about the new edition. We are particular- ly grateful to Jennifer Macomber for her skilled and meticulous care in shepherding the manuscript through production. Finally, we thank Anne Woodworth Gasque, who man- aged the process with ingenuity and grace, for her superb stewardship of this project.

Publication

T he Publication Manual of the American Psychological Association was first published in 1929 as a seven-page "standard of procedure, to which exceptions would doubtless be necessary, but to which reference might be made in cases of

doubt" (Bentley et a!., 1929, p. 57). Eighty years later, we launch the sixth edition of the Publication Manual in the same spirit. Over the years, the Publication Manual has grown by necessity from a simple set of style rules to an authoritative source on all aspects of scholarly writing, from the ethics of duplicate publication to the word choice that best reduces bias in language.

The rules of APA Style are drawn from an extensive body of psychological litera- ture, from editors and authors experienced in scholarly writing, and from recognized authorities on publication practices. This edition of the Publication Manual has been extensively revised to reflect new standards in publishing and new practices in infor- mation dissemination. Since the last edition of the manual was published, we have gone from a population that reads articles to one that "consumes content." New tech- nologies have made increasingly sophisticated analyses possible, just as they have accelerated the dissemination of those analyses in multiple forms, from blogs to per- sonal Web postings to articles published in online databases.

To provide readers with guidance on how these and other developments have affected scholarly publishing, we have reordered and condensed the manual signifi- cantly. Our first goal was to simplify the reader's job by compiling all information on a topic in a single place. We have ordered information in accordance with the publica- tion process, beginning with the idea stage and ending with the publication stage. We have retained and strengthened the basic rules of APA writing style and the guidelines on avoiding bias in language that were first published by APA more than 30 years ago. Most important, we have significantly expanded guidance on ethics, statistics, journal article reporting standards, electronic reference formats, and the construction of tables and figures.

Introduction

ORGANIZATION OF THE SIXTH EDITION

Key to this revision is an updated and expanded web presence, which exponential- ly increases the information we are able to provide. At www.apastyle.org, readers will find a full range of resources for learning APA Style as well as additional guidance on writing and publishing, which will evolve with changing standards and practices.

Organization of the Sixth Edition In Chapter 1, we acquaint readers with the types of articles common in scholarly pub- lications. We also describe the role of ethics in publishing and offer guidance in follow- ing best practices for compliance.

In Chapter 2, we define all parts of a scholarly manuscript, from title to appendix, emphasizing both function and form. We also summarize current reporting standards for journal articles. The chapter ends with sample papers that illustrate the rules of APA Style.

In Chapter 3, we offer basic guidance on planning and writing the article. We advise readers on how to organize their thoughts, choose effective words, and describe individuals with accuracy and sensitivity.

In Chapter 4, we instruct readers on the nuts and bolts of style: punctuation, spelling, capitalization, abbreviations, numbers, and statistics in text. Consistency in the use of these basic aspects of style is key to clear scientific communication.

In Chapter 5, we describe the effective use of graphic elements in text and provide readers with illustrations of graphic elements that are useful for the presentation of data in tables and figures.

In Chapter 6, we provide guidance on citing sources. We discuss ground rules for acknowledging contributions of others and for formatting quotations. We instruct readers on when and how to cite references in text and on how to construct a refer- ence list that contains everything readers need to locate each source.

In Chapter 7, we provide a comprehensive selection of reference examples in APA Style. The examples cover a range of categories, from periodicals to podcasts, with an emphasis on references to electronic formats.

In Chapter 8, we provide an overview of the journal publishing process. We emphasize the author's responsibilities in manuscript preparation and at each subse- quent stage of publication.

Specific Changes in the Sixth Edition General Approach

We considered two broad issues in planning this revision. First, given the wide use of the Publication Manual by readers outside the field of psychology, to what extent should this edition focus specifically on the APA journals program? Detailed infor- mation on APA journals is available on the web (see http://www.apa.org/journals/); each journal has its own web page, which includes specific instructions to authors. We decided to remove from the Publication Manual much of the APA-specific information that is readily accessible on the web, where guidelines are kept current. In this edition of the Publication Manual, we emphasize general principles that researchers need to know as well as principles of clear textual and visual communication.

INTRODUCTION

Second, to what extent should the Publication Manual be prescriptive rather than descriptive of current practices in the field? A section in the foreword to the fourth edi- tion is reJevant:

The Publication Manual presents explicit style requirements but ackndWledges that alternatives are sometimes necessary; authors should balance the rules of the Publication Manual with good judgment. Because the written language of psychology changes more slowly than psychology itself, the Publication Manual does not offer solutions for all stylistic problems. In that sense, it is a transition- al document: Its style requirements are based on the existing scientific literature rather than imposed on the literature. (American Psychological Association, 1994, p. xxiii)

Because of the diversity of practices in the social and behavioral sciénèes, we antici- pated that the Publication Manual would likely prescribe new direction for some subdisciplines and merely describe the current state of scientific reporting for other subdisciplines.

New and Expanded Content

Chapter 1. Because of the importance of ethical issues that affect the conduct of scien- tific inquiry, we have placed ethics discussions in this opening chapter and have signif- icantly expanded coverage of several topics. New guidance is included on determining authorship and terms of collaboration, duplicate publication, plagiarism and self- plagiarism, disguising of participants, validity of instrumentation, and making data available to others for verification.

Chapter 2. In Chapter 2, we provide comprehensive information on specific manuscript parts, which were located in several chapters in the last edition. For each manuscript part, we describe purpose and core content as well as how it should appear in text. This chapter has been significantly expanded with the addition of journal article reporting standards to help readers report empirical research with clarity and preci- sion. We also provide an expanded discussion of statistical methods, including guid- ance on reporting effect sizes. In addition, we provide a new section on the use and preparation of supplemental materials for the web. We close the chapter with a new selection of sample papers that instantiate elements of APA Style.

Chapter 3. In this chapter, we offer two areas with significantly changed content. First, we have simplified APA heading style to make it more conducive to electronic publi- cation. Second, we have updated guidelines for reducing bias in language to reflect cur- rent practices and preferences. A new section on presenting historical language that is inappropriate by present standards has been added, and examples of good and bad language choices have been expanded and moved to the web, where they are more accessible to all and can be easily updated.

Chapter 4. New content in Chapter 4 includes guidelines for reporting inferential statistics and a significantly revised table of statistical abbreviations. A new discus- slon of using supplemental files containing lengthy data sets and other media is also included.

HOW TO USE THE PUBLICATION MANUAL

ChapterS. Procedures for developing graphic material have changed dramatically since the last edition of the Publication Manual was published. This chapter contains signif- icantly expanded content on the electronic presentation of data. It will help readers understand the purpose of each kind of display and choose the best match for commu- nicating the results of the investigation. We provide new examples for a variety of dis- plays, including electrophysiological, imaging, and other biological data.

Chapter 6. In this chapter, we have consolidated information on all aspects of citations, beginning with guidance on how much to cite, how to format quotations, and how to navigate the permission process. Basic in-text citation styles and reference compo- nents are covered in detail. The discussion of electronic sources has been greatly expanded, emphasizing the role of the digital object identifier as a reliable way to locate information.

Chapter 7. Chapter 7 contains a significantly expanded set of reference examples, with an emphasis on electronic formats, for readers to use in mastering the changes described in Chapter 6. New examples have been added for a number of online sources, from data sets and measurement instruments to software and online discussion forums.

Chapter 8. Chapter 8 has been revised to focus more on the publication process and less on specific APA policies and procedures. It includes an expanded discussion of the func- tion and process of peer review; a discussion of ethical, legal, and policy requirements in publication; and guidelines on working with the publisher while the article is in press.

How to Use the Publication Manual The Publication Manual describes requirements for the preparation and submission of manuscripts for publication. Chapters in the Publication Manual provide substantive- ly different kinds of information and are arranged in the sequence in which one con- siders the elements of manuscript preparation, from initial concept through publica- tion. Although each chapter is autonomous, individuals new to the publication process may benefit from reading the book from beginning to end to get a comprehensive overview.

Organizational Aids We have included checklists throughout the book to help you organize tasks and review your progress. These are listed below.

We have also provided sample papers to illustrate applications of APA Style. These include a one-experiment paper (Figure 2.1, pp. 41—53), a two-experiment paper (Figure 2.2, pp. 54—56), and a sample paper reporting a meta-analysis (Figure 2.3, pp. 57—59).

INTRODUCTION

Format Aids Examples of points of style or format that appear throughout the book are in a con- trasting typeface. This typeface is intended to help you locate examples quickly.

This is an example of the typeface used to illustrate style points.

The following are other formatting aids that are designed to help the reader locate specific information quickly:

• A detailed table of contents lists the sections for each chapter and will help you locate categories of information quickly.

• An abbreviated table of contents appears inside the front cover for ease in locating broad categories of information.

• A list of tables and figures follows the table of contents and will help you locate spe- cific tables and figures.

• An abbreviated index of commonly used references appears inside the back cover.

We hope that these format aids will assist you in finding the instruction you need in the pages that follow.1

'You may find that the appearance of these pages occasionally deviates from APA Style rules. For example, sections may not be double-spaced and may not be in 12-point Times Roman typeface. APA Style rules are designed for ease of reading in manuscript form. Published work often takes a different form in accordance with professional design standards.

R esearch is complete only when the results are shared with the scientific com- munity. Although such sharing is accomplished in various ways, both formal and informal, the traditional medium for communicating research results is

the scientific journal. The scientific journal is the repository of the accumulated knowledge of a field.

The findings and analyses, the successes and failures, and the perspectives of many investigators over many years are recorded in the literature. Familiarity with the liter- ature allows an individual investigator to avoid needlessly repeating work that has been done before, to build on existing work, and in turn to contribute something new.

Just as each investigator benefits from the publication process, so the body of sci- entific literature depends for its vitality on the active participation of individual inves- tigators. Authors of scientific articles contribute most to the literature when they com- municate clearly and concisely.

In this chapter, we discuss several considerations that authors should weigh before writing for publication—considerations both about their own research and about the sci- entific publishing tradition. We begin by identifying the types of articles that appear in sci- entific journals. In the rest of the chapter, we focus on overarching ethical and legal stan- dards in publishing that must be addressed as a first step in planning an investigation.

Types of Articles Journal articles are usually reports of empirical studies, literature reviews, theoretical articles, methodological articles, or case studies. They are primary or original publica- tions. Members of the scientific community generally agree that the characteristics of these publications are that (a) articles represent research not previously published (i.e., first disclosure; for a discussion of duplicate publication, see section 1.09.), (b) articles

Writing for the Behavioral and Social Sciences

TYPES OF ARTICLES

are reviewed by peers before being accepted or rejected by a journal, and (c) articles are archival (i.e., retrievable for future reference).

1.01 Empirical Studies Empirical studies are reports of original research. These include secondary analyses that test hypotheses by presenting novel analyses of data not considered or addressed in previous reports. They typically consist of distinct sections that reflect the stages in the research process and that appear in the following sequence:

• introduction: development of the problem under investigation, including its histori- cal antecedents, and statement of the purpose of the investigation;

• method: description of the procedures used to conduct the investigation; • results: report of the findings and analyses; and • discussion: summary, interpretation, and implications of the results.

1.02 Literature Reviews Literature reviews, including research syntheses and meta-analyses, are critical evalu- ations of material that has already been published. In meta-analyses, authors use quan- titative procedures to statistically combine the results of studies. By organizing, inte- grating, and evaluating previously published material, authors of literature reviews consider the progress of research toward clarifying a problem. In a sense, literature reviews are tutorials, in that authors

• define and clarify the problem; • summarize previous investigations to inform the reader of the state of research; • identify relations, contradictions, gaps, and inconsistencies in the literature; and • suggest the next step or steps in solving the problem.

The components of literature reviews can be arranged in various ways (e.g., by group- ing research based on similarity in the concepts or theories of interest, methodological similarities among the studies reviewed, or the historical development of the field).

1.03 Theoretical Articles In theoretical articles, authors draw on existing research literature to advance theory. Literature reviews and theoretical articles are often similar in structure, but theoretical articles present empirical information only when it advances a theoretical issue. Authors of theoretical articles trace the development of theory to expand and refine theoretical constructs or present a new theory or analyze existing theory, pointing out flaws or demonstrating the advantage of one theory over another. In this type of article, authors customarily examine a theory's internal consistency and external validity. The sections of a theoretical article, like those of a literature review, can vary in order of their content.

1.04 Methodological Articles Methodological articles present new methodological approaches, modifications of existing methods, or discussions of quantitative and data analytic approaches to the

WRITING FOR THE BEHAVIORAL AND SOCIAL SCIENCES

community of researchers. These articles focus on methodological or data analytic approaches and introduce empirical data only as illustrations of the approach. Methodological articles are presented at a level that makes them accessible to the well- read researcher and provide sufficient detail for researchers to assess the applicabilit$' of the methodology to their research problem. Further, the article allows the reader to compare the proposed methods with those in current use and to implement the pro- posed methods. In methodological articles, highly technical materials (e.g., derivations, proofs, details of simulations) should be presented in appendices or as supplemental materials to improve the overall readability of the article.

1.05 Case Studies Case studies are reports of case materials obtained while working with an individual, a group, a community, or an organization. Case studies illustrate a problem; indicate a means for solving a problem; and/or shed light on needed research, clinical applica- tions, or theoretical matters. In writing case studies, authors carefully consider the bal- ance between providing important illustrative material and using confidential case material responsibly. (See section 1.11 for a discussion on confidentiality.)

1.06 Other Types of Articles Other, less frequently published types of articles include brief reports, comments and replies on previously published articles, book reviews, obituaries, letters to the edi- tor, and monographs. Consult with the editor of the journal to which you are con- sidering submitting the manuscript for specific information regarding these kinds of articles.

Ethical and Legal Standards in Publishing Much of the Publication Manual addresses scientific writing style. Style involves no inherent right or wrong. It is merely a conventional way of presenting information that is designed to ease communication. Different scholarly disciplines have different pub- lication styles.

In contrast, basic ethical and legal principles underlie all scholarly research and writing. These long-standing principles are designed to achieve three goals:

• to ensure the accuracy of scientific knowledge, • to protect the rights and welfare of research participants, and • to protect intellectual property rights.

Writers in the social and behavioral sciences work to uphold these goals and fol- low the principles that have been established by their professional associations. The following guidance is drawn from the "Ethical Principles of Psychologists and Code of Conduct" (hereinafter referred to as the APA Ethics Code; APA, 2002; see also http://www.apa.org/ethics), which contains standards that address the reporting and Publishing of scientific data. Note that the APA Ethics Code is not a static document— it may be revised and updated over time. Updates appear on the website as they become available.

ENSURING THE ACCURACY OF SCIENTIFIC KNOWLEDGE

Ensuring the Accuracy of Scientific Knowledge 1.07 Ethical Reporting of Research Results The essence of the scientific method involves observations that can be repeated and verified by others. Thus, psychologists do not fabricate or falsify data (APA Ethics Code Standard 8.lOa, Reporting Research Results). Modifying results, including visu- al images (for more discussion on visual images, see Chapter 5, section 5.29), to sup- port a hypothesis or omitting troublesome observations from reports to present a more convincing story is also prohibited (APA Ethics Code Standard S.Ola, Avoidance of False or Deceptive Statements).

Careful preparation of manuscripts for publication is essential, but errors can still occur. Authors are responsible for making such errors public if the errors are discov- ered after publication. First, inform the editor and the publisher so that a correction notice can be published. The goal of such a notice is to correct the knowledge base so that the error is brought to the attention of future users of the information. Each cor- rection notice is appended to the original article in an online database so that it will be retrieved whenever the original article is retrieved (for more details on correction notices, see section 8.06; APA Ethics Code Standard 8.lOb, Reporting Research Results).

1.08 Data Retention and Sharing Researchers must make their data available to the editor at any time during the review and publication process if questions arise with respect to the accuracy of the report. Refusal to do so can lead to rejection of the submitted manuscript without further con- sideration. In a similar vein, once an article is published, researchers must make their data available to permit other qualified professionals to confirm the analyses and results (APA Ethics Code Standard 8.14a, Sharing Research Data for Verification). Authors are expected to retain raw data for a minimum of five years after publication of the research. Other information related to the research (e.g., instructions, treatment manuals, software, details of procedures, code for mathematical models reported in journal articles) should be kept for the same period; such information is necessary if others are to attempt replication and should be provided to qualified researchers on request (APA Ethics Code Standard 6.01, Documentation of Professional and Scientific Work and Maintenance of Records).

APA encourages the open sharing of data among qualified investigators. Authors are expected to comply promptly and in a spirit of cooperation with requests for data sharing from other researchers. Before sharing data, delete any personally identifiable information or code that would make it possible to reestablish a link to an individual participant's identity. In addition to protecting the confidentiality of research partici- pants, special proprietary or other concerns of the investigator or sponsor of the research sometimes must be addressed as well. Generally, the costs of complying with the request should be borne by the requester.

To avoid misunderstanding, it is important for the researcher requesting data and the researcher providing data to come to a written agreement about the conditions under which the data are to be shared. Such an agreement must specify the limits on how the shared data may be used (e.g., for verification of already published results, for inclusion in meta-analytic studies, for secondary analysis). The written agreement

WRITING FOR THE BEHAVIORAL AND SOCIAL

should also include a formal statement about limits on the distribution of the shared data (e.g., it may be used only by the person requesting the data, it may be used by the person requesting the data and individuals the requestor directly supervises, or there are no limits on the further distribution of the data). Furthermore, the agreepierit should specify limits on the dissemination (conference presentations, internal journal articles, book chapters, etc.) of the results of analyses performed on the data and authorship expectations. Data-sharing arrangements must be entered into with proper consideration of copyright restrictions, consent provided by subjects, ments of funding agencies, and rules promulgated by the employer of the holder of the data (APA Ethics Code Standard 8.14b, Sharing Research Data for Verificáti&ñ).

1.09 Duplicate and Piecemeal Publication of Data The scientific literature is our institutional memory. Thus, reports in the literature must accurately reflect the independence of separate research efforts. Both duplicate and piecemeal publication of data constitute threats to these goals. Duplicate publication is the publication of the same data or ideas in two separate sources. Piecemeal publi- cation is the unnecessary splitting of the findings from one research effort into multi- pie articles.

Duplicate publication. Misrepresentation of data as original when they have been pub- lished previously is specifically prohibited by APA Ethics Code Standard 8.13,

:w Duplicate Publication of Data. Duplicate publication distorts the knowledge base by making it appear that there is more information available than really exists. It also

n- wastes scarce resources (journal pages and the time and efforts of editors and review- ers). The prohibition against duplicate publication is especially critical for the cumula-

id tive knowledge of the field. Duplicate publication can give the erroneous impression that findings are more replicable than is the case or that particular conclusions are more strongly supported than is warranted by the cumulative evidence. Duplicate pub-

nt lication can also lead to copyright violations; authors cannot assign the copyright for in the same material to more than one publisher. if Previously published research. Authors must not submit to an APA journal a man-

uscript describing work that has been published previously in whole or in substantial Ic part elsewhere, whether in English or in another language. More important, authors

should not submit manuscripts that have been published elsewhere in substantially rs similar form or with substantially similar content. Authors in doubt about what con- ta stitutes prior publication should consult with the editor of the journal in question. le This policy regarding duplicate publication does not necessarily exclude from con- al sideration manuscripts previously published in abstracted form (e.g., in the proceed-

ings of an annual meeting) or in a periodical with limited circulation or availability i.e (e.g., in a report by a university department, by a government agency, or in a U.S. dis-

sertation). This policy does exclude from consideration the same or overlapping mate- rial that has appeared in a publication that has been offered for public sale, such as conference proceedings or a book chapter; such a publication does not meet the crite- rion of "limited circulation." Publication of a brief report in an APA journal is with the understanding that an extended report will not be published elsewhere because APA brief reports include sufficient descriptions of methodology to allow for replica- tion; the brief report is the archival record for the work. Similarly, the restraints against

____

ENSURING THE ACCURACY OF SCIENTIFIC KNOWLEDGE

duplicate publication do not preclude subsequent reanalysis of published data in light of new theories or methodologies, if the reanalysis is clearly labeled as such and pro- vides new insights into the phenomena being studied.

Acknowledging and citing previous work Authors sometimes want to publish what is essentially the same material in more than one venue to reach different audiences. However, such duplicate publication can rarely be justified, given the ready accessibil- ity of computerized retrieval systems for published works. If it is deemed scientifically necessary to re-present previously published material—for instance, in reports of new analyses or to frame new research that follows up on previous work from the authors' laboratory—the following conditions must be met:

1. The amount of duplicated material must be small relative to the total length of the text.

2. The text must clearly acknowledge in the author note and other relevant sections of the article (i.e., Method and/or Result sections) that the information was reported previously, and the citation to the previous work must be given.

3. Any republished tables and figures must be clearly marked as reprinted or adapted, and the original source must be provided both in the text and in a footnote to the table or figure.

4. The original publication venue must be clearly and accurately cited in the reference list (see also the discussion on self-plagiarism in section 1.10).

When the original publication has multiple authors and the authorship is not iden- tical on both publications, it is important that all authors receive agreed-upon credit (e.g., in an author note) for their contributions in the later publication.

Piecemeal publication. Authors are obligated to present work parsimoniously and as completely as possible within the space constraints of journal publications. Data that can be meaningfully combined within a single publication should be presented to- gether to enhance effective communication. Piecemeal, or fragmented, publication of research findings can be misleading if multiple reports appear to represent independ- ent instances of data collection or analyses; distortion of the scientific literature, espe- cially in reviews or meta-analyses, may result. Piecemeal publication of several reports of the results from a single study is therefore undesirable unless there is a clear benefit to scientific communication. It may be quite difficult to determine whether such a ben- efit exists when multiple dependent variables that were observed in the same sample and at the same time are reported in separate manuscripts. Authors who wish to divide the report of a study into more than one article should inform the editor and provide such information as the editor requests. Whether the publication of two or more reports based on the same or on closely related research constitutes fragmented publi- cation is a matter of editorial judgment.

Reanalysis of published data. There may be times, especially in instances of large- scale, longitudinal, or multidisciplinary projects, when it is both necessary and appro- priate to publish multiple reports. Multidisciplinary projects often address diverse top- ics, and publishing in a single journal may be inappropriate. Repeated publication from a longitudinal study is often appropriate because the data at different ages make unique scientific contributions. Further, useful knowledge should be made available to others as soon as possible, which is precluded if publication is withheld until all the studies are completed.

1

I WRITING FOR THE BEHAVIORAL AND SOCIAL SCIENCES

As multiple reports from large-scale or longitudinal studies are created, authors are obligated to cite prior reports on the project to help the reader understand the work accurately. For example, in the early years of a longitudinal study, one might cite all previous publications from it. For a well-known or long-term longitudinal study, one

iat might cite the original publication, a more recent summary, and earlier articles that es. focused on the same or related scientific questions addressed in the current report. il- Often it is not necessary to repeat the description of the design and methods of a Ion- Ily gitudinal or large-scale project in its entirety. Authors may refer the reader to an earli-

er publication for this detailed information. It is important, however, to provide suffi- rs cient information so that the reader can evaluate the current report. It is also important

to make clear the degree of sample overlap in multiple reports from large studies. Again, authors should inform and consult with the editor prior to the submission of a manuscript of this type.

of Alerting the editor. Whether the publication of two or more reports based on the same ed or closely related research constitutes duplicate publication is a matter of editorial

judgment, as is the determination of whether the manuscript meets other publication d, criteria. Any prior publication should be noted (see previous section on acknowledg- he ing and citing previous work) and referenced in the manuscript, and authors must

inform the journal editor of the existence of any similar manuscripts that have already ce been published or accepted for publication or that may be submitted for concurrent

consideration to the same journal or elsewhere. The editor can then make an informed judgment as to whether the submitted manuscript includes sufficient new information

lit to warrant consideration. If, during the review or production process, a manuscript is discovered to be in violation of duplicate publication policies and authors have failed to inform the editor of the possible violation, then the manuscript can be rejected with-

as out further consideration. If such a violation is discovered after publication in an APA tat journal, appropriate action such as retraction by the publisher or notice of duplicate

publication will be taken. of Journal articles sometimes are revised for publication as book chapters. Authors d- have a responsibility to reveal to the reader that portions of the new work were previ-

ously published and to cite and reference the source. If copyright is owned by a pub- lisher or by another person, authors must acknowledge copyright and obtain permis-

fit sion to adapt or reproduce. n-

de 1.10 Plagiarism and Self-Plagiarism

de Plagiarism. Researchers do not claim the words and ideas of another as their own; they re give credit where credit is due (APA Ethics Code Standard 8.11, Plagiarism). Ii- Quotation marks should be used to indicate the exact words of another. Each time you

paraphrase another author (i.e., summarize a passage or rearrange the order of a sen- tence and change some of the words), you need to credit the source in the text. The following paragraph is an example of how one might appropriately paraphrase some of the foregoing material in this section.

As stated in the sixth edition of the Publication Manual of the American to Ps ychological Association (APA, 2010), the ethical principles of scientific publica- Eie tion are designed to ensure the integrity of scientific knowledge and to protect

the intellectual property rights of others. As the Publication Manual explains,

Mt I PROTECTING THE RIGHTS AND WELFARE OF RESEARCH PARTICIPANTS

authors are expected to correct the record if they discover errors in their publi- cations; they are also expected to give credit to others for their prior work when it is quoted or paraphrased.

The key element of this principle is that authors do not present the work of anoth- er as if it were their own work. This can extend to ideas as well as written words. If authors model a study after one done by someone else, the originating author should be given credit. If the rationale for a study was suggested in the Discussion section of someone else's article, that person should be given credit. Given the free exchange of ideas, which is very important to the health of intellectual discourse, authors may not know where an idea for a study originated. If authors do know, however, they should acknowledge the source; this includes personal communications. (For additional infor- mation on quotations and paraphrasing, see sections 6.03—6.08; for instructions on referencing publications and personal communications, see sections 6.11—6.20.)

Self-plagiarism. Just as researchers do not present the work of others as their own (pla- giarism), they do not present their own previously published work as new scholarship (self-plagiarism). There are, however, limited circumstances (e.g., describing the details of an instrument or an analytic approach) under which authors may wish to duplicate without attribution (citation) their previously used words, feeling that extensive self- referencing is undesirable or awkward. When the duplicated words are limited in scope, this approach is permissible. When duplication of one's own words is more extensive, citation of the duplicated words should be the norm. What constitutes the maximum acceptable length of duplicated material is difficult to define but must conform to legal notions of fair use. The general view is that the core of the new document must consti- tute an original contribution to knowledge, and only the amount of previously pub- lished material necessary to understand that contribution should be included, primarily in the discussion of theory and methodology. When feasible, all of the author's own words that are cited should be located in a single paragraph or a few paragraphs, with a citation at the end of each. Opening such paragraphs with a phrase like "as I have pre- viously discussed" will also alert readers to the status of the upcoming material.

Protecting the Rights and Welfare of Research Participants 1.11 Rights and Confidentiality of Research Participants Certification of standards. Standards 8.01—8.09 of the APA Ethics Code specify the princi- ples psychologists are to follow in conducting research with humans and animals. Authors, regardless of field, are required to certify that they have followed these standards as a precondition of publishing their articles in APA journals (see http://www.apa.org/ journals; see also Figure 8.2, pp. 233—234). Authors are also encouraged to include such certifications in the description of participants in the text of the manuscript. Failure to fol- low these standards can be grounds for rejecting a manuscript for publication or for retraction of a published article.

Protecting confidentiality. When researchers use case studies to describe their research, they are prohibited from disclosing "confidential, personally identifiable information concerning their patients, individual or organizational clients, students, research par-

WRITING FOR THE BEHAVIORAL AND SOCIAL SCIENCES

- ticipants, or other recipients of their services" (APA Ethics Code Standard 4.07, Use of Confidential Information for Didactic or Other Purposes). Confidentiality in case stud- ies is generally handled by one of two means. One option is to prepare the descriptive case material, present it to the subject of the case report, and obtain written consent for its publication from the subject. In doing so, however, one must be careful not to exploit persons over whom one has supervisory, evaluative, or other authority such as clients,

ild patients, supervisees, employees, or organizational clients (see APA Ethics Code of Standard 3.08, Exploitative Relationships). The other option is to disguise some aspects of of the case material so that neither the subject nor third parties (e.g., family members,

employers) are identifiable. Four main strategies have emerged for achieving this: (a) tld altering specific characteristics, (b) limiting the description of specific characteristics, (c)

obfuscating case detail by adding extraneous material, and (d) using composites. Such disguising of cases is a delicate issue because it is essential not to change vari-

ables that would lead the reader to draw false conclusions related to the phenomena

[a- being described (Tuckett, 2000). For example, altering the subject's gender in a case illus-

tip trating a promising therapy for rape trauma might compromise its educative value if the

ils client—patient's gender played a significant role in the treatment. Subject details should be

Lte omitted only if they are not essential to the phenomenon described. Subject privacy, how-

If- ever, should never be sacrificed for clinical or scientific accuracy. Cases that cannot ade- quately disguise identifiable subject information should not be submitted for publication.

re, t For additional information on the presentation of case material, see VandenBos (2001).

m! al 1.12 Conflict of Interest

In all scientific disciplines, professional communications are presumed to be based on

ly objective interpretations of evidence and unbiased interpretation of fact. An author's

in economic and commercial interests in products or services used or discussed in a paper may color such objectivity. Although such relations do not necessarily constitute a con-

•e- flict of interest, the integrity of the field requires disclosure of the possibilities of such

• potentially distorting influences where they may exist. In general, the safest and most • open course of action is to disclose in an author note activities and relationships that

if known to others might be viewed as a conflict of interest, even if you do not believe that any conflict or bias exists.

Whether an interest is significant will depend on individual circumstances and can- not be defined by a dollar amount. Holdings in a company through a mutual fund are not ordinarily sufficient to warrant disclosure, whereas salaries, research grants, con- sulting fees, and personal stock holdings would be. Being the copyright holder of and/or recipient of royalties from a psychological test might be another example. Participation on a board of directors or any other relationship with an entity or person that is in some way part of the paper should also be carefully considered for possible disclosure.

In addition to disclosure of possible sources of positive bias, authors should also carefully consider disclosure when circumstances could suggest bias against a product, service, facility, or person. For example, having a copyright or royalty interest in a competing psychological test or assessment protocol might be seen as a possible source of negative bias against another test instrument.

The previous examples refer to possible conflicts of interest of a researcher in the con- duct of the research. It is important to recognize that reviewers of research reports also have potential conflicts of interest. In general, one should not review a manuscript from a Colleague or collaborator, a close personal friend, or a recent student. Typically, the action

PROTECTING INTELLECTUAL PROPERTY RIGHTS

editor will not select individuals to be reviewers in which this obvious conflict of interest may exist. Howeveç if this might occuç a potential reviewer should consult with the action editor about whether recusal from the evaluation process would be appropriate.

Reviewers also have an ethical obligation to be open and fair in assessing a man- uscript without bias. If for any reason a reviewer may find this difficult, it is appropri- ate to discuss the potential conflict of interest with the action editor as soon as this sit- uation becomes apparent.

Last, reviewers have an obligation to maintain the confidentiality of a manuscript. This means, in general, that one does not discuss the manuscript with another individ- ual. Moreover, as noted in section 1.14, "editors and reviewers may not use the mate- rial from an unpublished manuscript to advance their own or others' work without the author's consent."

Protecting Intellectual Property Rights 1.13 Publication Credit Authorship is reserved for persons who make a substantial contribution to and who accept responsibility for a published work.

Definition of authorship. Individuals should only take authorship credit for work they have actually performed or to which they have substantially contributed (APA Ethics Code Standard 8.12a, Publication Credit). Authorship encompasses, therefore, not only those who do the actual writing but also those who have made substantial scientific con- tributions to a study. Substantial professional contributions may include formulating the problem or hypothesis, structuring the experimental design, organizing and conducting the statistical analysis, interpreting the results, or writing a major portion of the paper. Those who so contribute are listed in the byline. Lesser contributions, which do not con- stitute authorship, may be acknowledged in a note (see section 2.03). These contributions may include such supportive functions as designing or building the apparatus, suggesting or advising about the statistical analysis, collecting or entering the data, modifying or structuring a computer program, and recruiting participants or obtaining animals. Conducting routine observations or diagnoses for use in studies does not constitute authorship. Combinations of these (and other) tasks, however, may justify authorship.

Determining authorship. As early as practicable in a research project, the collaborators should decide on which tasks are necessary for the project's completion, how the work

F will be divided, which tasks or combination of tasks merits authorship credit, and on what level credit should be given (first author, second author, etc.). Collaborators may need to reassess authorship credit and order if changes in relative contribution are made in the course of the project (and its publication). This is especially true in faculty— student collaborations, when students may need more intensive supervision than origi- nally anticipated, when additional analyses are required beyond the scope of a student's current level of training (Fisher, 2003), or when the level of the contribution of the stu- dent exceeds that originally anticipated.

When a paper is accepted by an editor, each person listed in the byline must verify in writing that he or she agrees to serve as an author and accepts the responsibilities of authorship (see the section on author responsibilities at the beginning of Chapter 8).

WHITING FOR THE BEHAVIORAL AND SOCIAL SCIENCES

Order of authorship. Authors are responsible for determining authorship and for spec- ifying the order in which two or more authors' names appear in the byline. The gen- eral rule is that the name of the principal contributor should appear first, with subse-

in- quent names in order of decreasing contribution, but this convention can vary froth ri- field to field. If authors played equal roles in the research and publication of their ;it- study, they may wish to note this in the author note (see section 2.03 for more infor-

mation on author notes). pt. Principal authorship and the order of authorship credit should accurately reflect id- the relative contributions of persons involved (APA Ethics Code Standard 8.12b, te- Publication Credit). Relative status (i.e., department chair, junior faculty member, stu- :he dent) should not determine the order of authorship. Because doctoral work is expect-

ed to represent an independent and original contribution devised by students, except under rare circumstances, students should be listed as the principal author of any mul- tiauthored papers substantially based on their dissertation (APA Ethics Code Standard 8.12c, Publication Credit). Unusual exceptions to doctoral student first authorship might occur when the doctoral dissertation is published as part of a collection of stud- ies involving other researchers (Fisher, 2003). Whether students merit principal author- ship on master's-level or other predoctoral research will depend on their specific con- tributions to the research. When master's-level students make the primary contributions to a study, they should be listed as the first author. When students are

Ley just beginning to acquire skills necessary to make a primary scientific contribution, ics they may conduct master's theses that involve the opportunity to learn these skills ily through collaboration on a faculty-originated project. In such cases, authorship should n- be determined by the relative contributions of student and faculty member to the proj- he ect (Fisher, 2003). ng er. 1.14 Reviewers

Editorial review of a manuscript requires that the editors and reviewers circulate and

ng discuss the manuscript. During the review process, the manuscript is a confidential and

or privileged document. Editors and reviewers may not, without authors' explicit permis-

Is. sion, quote from a manuscript under review or circulate copies of it for any purpose

ite other than editorial review (APA Ethics Code Standard 8.15, Reviewers; see section 8.01 for a detailed discussion of the peer review process). If reviewers for APA journals wish to consult with a colleague about some aspect of the manuscript, the reviewer must

rs request permission from the editor prior to approaching the colleague. Publishers have rk different policies on this, and reviewers should consult with the editor about this mat-

ter. In addition, editors and reviewers may not use the material from an unpublished ay manuscript to advance their own or others' work without the author's consent. de

1.15 Author's Copyright on an Unpublished Manuscript t's Authors are protected by federal statute against unauthorized use of their unpublished

manuscripts. Under the Copyright Act of 1976 (title 17 of the United States Code), an unpublished work is copyrighted from the moment it is fixed in tangible form—for example, typed on a page. Copyright protection is "an incident of the process of

of authorship" (U.S. Copyright Office, 1981, p. 3). Until authors formally transfer copy- right (see section 8.05), they own the copyright on an unpublished manuscript, and all

PROTECTING INTELLECTUAL PROPERTY RIGHTS

exclusive rights due the copyright owner of a published work are also due authors of an unpublished work. To ensure copyright protection, include the copyright notice on all published works (e.g., Copyright [year] by [name of copyright holder]). The notice need not appear on unpublished works; nonetheless, it is recommended that a copy- right notice be included on all works, whether published or not. Registration of copyright provides a public record and is usually a prerequisite for any legal action.

1.16 Planning for Ethical Compliance Regardless of the type of article involved, attention to ethical concerns begins long before a manuscript is submitted for publication. Authors submitting a manuscript to an APA journal are required to submit a form stating their compliance with ethical standards for publication as well as a form disclosing any conflicts of interest (see Chapter 8, Figures 8.2 and 8.3, pp. 233—235) once a manuscript is accepted. We encourage authors to consult these forms before beginning their research project and at regular intervals throughout the entire research process. Whether or not the work will be submitted to an APA journal, issues related to institutional approval, informed consent, deception in research, and participant protections should be carefully considered while the research is in the planning stages and may be the basis of questions for editors or reviewers (see Chapter 8). In particular, we urge researchers to review the following checklist.

Ethical Compliance Checklist

D Have you obtained permission for use of unpublished instruments, proce- dures, or data that other researchers might consider theirs (proprietary)?

S Have you properly cited other published work presented in portions of your manuscript?

El Are you prepared to answer questions about institutional review of your study or studies?

S Are you prepared to answer editorial questions about the informed consent and debriefing procedures you used?

S If your study involved animal subjects, are you prepared to answer editorial questions about humane care and use of animals in research?

U Have all authors reviewed the manuscript and agreed on responsibility for its content?

S Have you adequately protected the confidentiality of research participants, clients—patients, organizations, third parties, or others who were the source of information presented in this manuscript?

S Have all authors agreed to the order of authorship?

S Have you obtained permission for use of any copyrighted material you have included?

Manuscript Structure and Content

in is

ee

Jn this chapter, we describe the structure of the manuscript, with a focus on function

and format. For each manuscript element, we detail current expectations for the content. In each section, the following kinds of information are included:

• a definition or description of the manuscript part, • specific guidelines on content to be included, and • guidelines on how the part should appear in text.'

In this edition of the Publication Manual, we present updated journal article reporting standards, and these are also discussed in this chapter. These reporting stan- dards relate to material recommended to appear in the abstract, the introduction of the research problem, the method section, the results, and the discussion of the results. Also presented are three specific modules relating to studies with manipulated condi- tions or interventions. The chapter ends with sample papers that illustrate the function and format of the sections described.

Journal Article Reporting Standards Reporting standards provide a degree of comprehensiveness in the information that is routinely included in reports of empirical investigations. The motivation for the devel- opment of reporting standards has come from within the disciplines of the behavioral, social, educational, and medical sciences. Uniform reporting standards make it easier to generalize across fields, to more fully understand the implications of individual stud- ies, and to allow techniques of meta-analysis to proceed more efficiently. Also, decision makers in policy and practice have emphasized the importance of understanding how research was conducted and what was found. A set of comprehensive reporting stan- dards facilitates this understanding.

'Note that guidelines for the formatting and preparation of the complete manuscript can be found in section 8.03.

JOURNAL ARTICLE REPORTING STANDARDS

Reporting standards are based on the research design and implementation of the study being reported, not on the topical focus of the study or the particular journal that might serve as the vehicle for its publication. Reporting standards are emergent and have not yet been developed for all types of studies.

In the next section, we describe a set of reporting standards relating to the mate- rial recommended to appear in (a) the abstract; (b) the introduction of the research problem; (c) subsections of the method section describing the characteristics of the par- ticipants; sampling procedures; sample size, power, and precision; measures and covari- ates; and the general descriptor of the research design; (d) the statistical results; and (e) the discussion of results. These standards relate to all types of research designs. Then we present three specific modules relating to studies with manipulated conditions or interventions. You can use (or a journal editor may ask you to use) these modules in addition to the general template if they are relevant to the research at hand. One mod- ule contains standards for describing the experimental manipulation or intervention itself, and the other two modules describe features of designs with experimental (i.e., random assignment) and quasi-experimental (i.e., nonrandom assignment) research designs. We also provide a flow chart to help you describe how subjects moved through the experimental or quasi-experimental study. In the same spirit, we include standards for reports of meta-analyses. Before you begin to write a manuscript, con- sult the particular journal to which you are considering submitting and see whether there are journal-specific guidelines regarding your research design.

We relied heavily on previous efforts to construct reporting standards in develop- ing the standards presented here. For example, for the Journal Article Reporting Standards, Consolidated Standards of Reporting Trials (CONSORT; 2007; see http://www.consort-statement.org/) and Transparent Reporting of Evaluations With Nonexperimental Designs (TREND; see http://www.trend-statement.org/asp/ trend.asp) were used. Four earlier efforts contributed to the meta-analysis reporting standards. A complete description of how the standards were developed can be found in "Reporting Standards for Research in Psychology: Why Do We Need Them? What Might They Be?" (APA Publications and Communications Board Working Group on Journal Article Reporting Standards, 2008).

Four sets of guidelines, which can be found in the Appendix, have been created to help you decide which elements are relevant to your study. These guidelines are from the American Psychologist article (see previous paragraph) and include entries beyond those discussed in this chapter. For information on content, refer to Table 1 of the Appendix, Journal Article Reporting Standards (JARS): Information Recommended for Inclusion in Manuscripts That Report New Data Collections Regardless of Research Design. The additional modules for designs involving experimental manipu- lations and interventions can be found in Table 2 of the Appendix, Module A: Reporting Standards for Studies With an Experimental Manipulation or Intervention (in Addition to Material Presented in Table 1) and Table 3 of the Appendix, Reporting Standards for Studies Using Random and Nonrandom Assignment of Participants to Experimental Groups. The fourth set of guidelines is titled Meta-Analysis Reporting Standards [MARS]: Information Recommended for Inclusion in Manuscripts Reporting Meta-Analyses, which can be found in Table 4 of the Appendix.

Not everything in these guidelines will be relevant to every article you prepare. Also, as descriptions of research expand, so does the space needed to report them.: Technological changes now allow authors to supplement their articles with additional

the online-only material to facilitate complete reporting. Most scholarly publishers, ma! including the APA, now make available to authors online supplemental archives that

can be used to store supplemental materials associated with the articles that appear in print. So, some of the material in the appendices may not appear in the published arti-

ate- cle itself but rather in an online supplemental archive. We discuss supplemental mate- rch na1 more fully in section 2.13. )ar- an-

Manuscript Elements 2.01 Title A title should summarize the main idea of the manuscript simply and, if possible, with

-ion style. It should be a concise statement of the main topic and should identify the van- I e

ables or theoretical issues under investigation and the relationship between them. An

Lrch example of a good title is "Effect of Transformed Letters on Reading Speed."

ved A title should be fully explanatory when standing alone. Although its principal

d function is to inform readers about the study, a title is also used as a statement of arti- cle content for abstracting and reference purposes in databases such as APA's PsycINFO.

-h A good title is easily shortened to the running head used within the published article.

- er Titles are commonly indexed and compiled in numerous reference works. Therefore,

avoid words that serve no useful purpose; they increase length and can mislead indexers. For example, the words method and results do not normally appear in a title, nor shouldmg

- such terms as A Study of or An Experimental Investigation of. Occasionally a term such see

as a research synthesis or a meta-analysis or fMRI study of conveys important informa- it

tion for the potential reader and is included in the title. Avoid using abbreviations in a title; spelling out all terms helps ensure accurate, complete indexing of the article. The

.mg recommended length for a title is no more than 12 words.

Linu The title should be typed in uppercase and lowercase letters, centered between the

left and right margins, and positioned in the upper half of the page.

ito 2.02 Author's Name (Byline) and Institutional Affiliation om Every manuscript includes the name of the author and the institutional affiliation of nd the author when the research was conducted. the ded Author's name (byline). The preferred form of an author's name is first name, middle

of initial(s), and last name; this form reduces the likelihood of mistaken identity. To pu- assist researchers as well as librarians, use the same form for publication throughout A: your career; that is, do not use initials on one manuscript and the full name on a later

:ion one. Determining whether Juanita A. Smith is the same person as J. A. Smith, J. :ing Smith, or A. Smith can be difficult, particularly when citations span several years and

to institutional affiliations change. Omit all titles (e.g., Dr., Professor) and degrees (e.g., :ing

PhD, PsyD, EdD).

pts Institutional affiliation. The affiliation identifies the location where the author or authors were when the research was conducted, which is usually an institution. Include a dual affiliation only if two institutions contributed substantial support to the study. Include no more than two affiliations per author. When an author has no institutional affiliation, list the city and state of residence below the author's name. If the institu-

tional affiliation has changed since the work was completed, give the current affilia- tion in the author note (see Table 2.1).

The names of the authors should appear in the order of their contributions, cen- tered between the side margins. For names with suffixes (e.g., Jr. and III), separate the suffix from the rest of the name with a space instead of a comma. The institutional affiliation should be centered under the author's name, on the next line.

2.03 Author Note An author note appears with each printed article to identify each author's departmen- tal affiliation, provide acknowledgments, state any disclaimers or perceived conflict of interest, and provide a point of contact for the interested reader. (Students should note that an author note is usually not a requirement for theses and dissertations.) Notes should be arranged as follows.

First paragraph: Complete departmental affiliation. Identify departmental affiliations at the time of the study for all authors. Format as follows: name of the author as it appears in the byline, comma, department name, comma, university name, semicolon, next author name, and so on, and end with a period. If an author is not affiliated with an institution, provide the city and state (provide city and country for authors whose affil- iations are outside of the United States, and include province for authors in Canada or Australia). No degrees should be given, and state names should be spelled out.

Second paragraph: Changes of affiliation (if any). Identify any changes in author affili- ation subsequent to the time of the study. Use the following wording: [author's name) is now at [affiliationl. The affiliation should include the department and institution.

MANUSCRIPT STRUCTURE AND CONTENT

Third paragraph. Acknowledgments. Identify grants or other financial support (and the source, if

appropriate) for your study; do not precede grant numbers by No. or #. Next, acknowledge colleagues who assisted in conducting the study or critiquing the manu- script. Do not acknowledge the persons routinely involved in the review and accept- ance of manuscripts—peer reviewers or editors, associate editors, and consulting edi- tors of the journal in which the article is to appear. (If you would like to acknowledge a specific idea raised by a reviewer, do so in the text where the idea is discussed.) In this paragraph, also explain any special agreements concerning authorship, such as if authors contributed equally to the study. End this paragraph with thanks for personal assistance, such as in manuscript preparation.

Special circumstances. If there are any special circumstances, disclose them before the acknowledgments in the third paragraph. For example, if the manuscript is based on data also used in a previously published report (e.g., a longitudinal study) or a doctoral dissertation, state that information in this paragraph. Also, acknowledge the publication of related reports (e.g., reports on the same database). If any relationships may be perceived as a conflict of interest (e.g., if you own stock in a company that manufactures a drug used in your study), explain them here. If your employer or granting organization requires a disclaimer stating, for example, that the research reported does not reflect the views of that organization, such a statement is included in this paragraph.

2.04 Abstract An abstract is a brief, comprehensive summary of the contents of the article; it allows readers to survey the contents of an article quickly and, like a title, it enables persons inter- ested in the document to retrieve it from abstracting and indexing databases. Most schol-

MANUSCRIPT ELEMENTS

arty journals require an abstract. Consult the instructions to authors or web page of the journal to which you plan to submit your articte for any journal-specific instructions.

A well-prepared abstract can be the most important singte paragraph in an articte. Most peopte have their first contact with an articte by seeing just the abstract, usually in comparison with severat other abstracts, as they are doing a titerature search. Readers frequently decide on the basis of the abstract whether to read the entire arti- cle. The abstract needs to be dense with information. By embedding key words in your abstract, you enhance the user's ability to find it. A good abstract is

• accurate: Ensure that the abstract correctty reflects the purpose and content of the manuscript. Do not inctude information that does not appear in the body of the manuscript. If the study extends or replicates previous research, note this in the abstract and cite the author's tast name and the year of the relevant report. Comparing an abstract with an outtine of the manuscript's headings is a usefut way to verify its accuracy.

• nonevaluative: Report rather than evaluate; do not add to or comment on what is in the body of the manuscript.

• coherent and readabte: Write in ctear and concise tanguage. Use verbs rather than their noun equivalents and the active rather than the passive voice (e.g., investigated rather than an investigation on The authors presented the results instead of Results were presented). Use the present tense to describe conctusions drawn or resutts with continuing appticability; use the past tense to describe specific variables maniputat- ed or outcomes measured.

• concise: Be brief, and make each sentence maximally informative, especially the tead sentence. Begin the abstract with the most important points. Do not waste space by repeating the title. Inctude in the abstract onty the four or five most important con- cepts, findings, or imptications. Use the specific words in your abstract that you think your audience will use in their electronic searches.

An abstract of a report of an empirical study shoutd describe

• the problem under investigation, in one sentence if possible; • the participants, specifying pertinent characteristics such as age, sex, and ethnic

andlor raciat group; in animat research, specifying genus and species; • the essential features of study method—you have a timited number of words so restrict

your description to essential and interesting features of the study methodotogy— particutarty those tikety to be used in etectronic searches;

• the basic findings, inctuding effect sizes and confidence intervals and/or statistical significance tevels; and

• the conclusions and the implications or applications.

An abstract for a literature review or meta-analysis should describe

• the probtem or relation(s) under investigation; • study eligibility criteria; • type(s) of participants inctuded in primary studies; • main resutts (inctuding the most important effect sizes) and any important modera-

tors of these effect sizes;

he • conclusions (including limitations); and • implications for theory, policy, and/or practice.

An abstract for a theory-oriented paper should describe

:h. • how the theory or model works and/or the principles on which it is based and ti- • what phenomena the theory or model accounts for and linkages to empirical results. ur

An abstract for a methodological paper should describe

he • the general class of methods being discussed;

he • the essential features of the proposed method;

he • the range of application of the proposed method; and

rt. • in the case of statistical procedures, some of its essential features such as robustness

ay or power efficiency.

An abstract for a case study should describe

• the subject and relevant characteristics of the individual, group, community, or organization presented;

an • the nature of or solution to a problem illustrated by the case example; and • the questions raised for additional research or theory.

th Do not exceed the abstract word limit of the journal to which you are submitting it- your article. Word limits vary from journal to journal and typically range from 150 to

250 words. For information on how abstracts are used to retrieve articles, consult

ad Record Structure for APA Databases (Sick, 2009).

by When preparing your manuscript, begin the abstract on a new page and identify it

in- with the running head or abbreviated title and the page number 2. The label Abstract should appear in uppercase and lowercase letters, centered, at the top of the page. Type the abstract itself as a single paragraph without paragraph indentation.

2.05 Introduction Introduce the problem. The body of a manuscript opens with an introduction that pres- ents the specific problem under study and describes the research strategy. Because the introduction is clearly identified by its position in the manuscript, it does not carry a heading labeling it the introduction.

Before writing the introduction, consider the following questions:

• Why is this problem important? • How does the study relate to previous work in the area? If other aspects of this study

have been reported previously, how does this report differ from, and build on, the earlier report?

I What are the primary and secondary hypotheses and objectives of the study, and what, if any, are the links to theory?

• How do the hypotheses and research design relate to one another? • What are the theoretical and practical implications of the study?

A good introduction answers these questions in just a few pages and, by summa- rizing the relevant arguments and the past evidence, gives the reader a firm sense of what was done and why.

MANUSCRIPT ELEMENTS

Explore importance of the problem. State why the problem deserves new research. For basic research, the statement about importance might involve the need to resolve any inconsistency in results of past work and/or extend the reach of a theoretical formula- tion. For applied research, this might involve the need to solve a social problem or treat a psychological disorder. When research is driven by the desire to resolve controversial issues, all sides in the debate should be represented in balanced measure in the intro-

______

duction. Avoid animosity and ad hominem arguments in presenting the controversy.

_______

Conclude the statement of the problem in the introduction with a brief but formal

_______

statement of the purpose of the research that summarizes the material preceding it. For literature reviews as well as theoretical and methodological articles, also clearly state the reasons that the reported content is important and how the article fits into, the cumulative understanding of the field.

Describe relevant scholarship. Discuss the relevant related literature, but do not feel compelled to include an exhaustive historical account. Assume that the reader is knowledgeable about the basic problem and does not require a complete accounting of its history. A scholarly description of earlier work in the introduction provides a summary of the most recent directly related work and recognizes the priority of the work of others. Citation of and specific credit to relevant earlier works are signs of scientific and scholarly responsibility and are essential for the growth of a cumula- tive science. In the description of relevant scholarship, also inform readers whether other aspects of this study have been reported on previously and how the current use of the evidence differs from earlier uses. At the same time, cite and reference only works pertinent to the specific issue and not those that are of only tangential or gen- eral significance. When summarizing earlier works, avoid nonessential details; instead, emphasize pertinent findings, relevant methodological issues, and major conclusions. Refer the reader to general surveys or research syntheses of the topic if they are available.

Demonstrate the logical continuity between previous and present work. Develop the problem with enough breadth and clarity to make it generally understood by as wide a professional audience as possible. Do not let the goal of brevity lead you to write a statement intelligible only to the specialist.

State hypotheses and their correspondence to research design. After you have intro- duced 'the problem and have developed the background material, explain your approach to solving the problem. In empirical studies, this usually involves stating your hypotheses or specific question and describing how these were derived from theo- ry or are logically connected to previous data and argumentation. Clearly develop the rationale for each. Also, if you have some hypotheses or questions that are central to your purpose and others that are secondary or exploratory, state this prioritization. Explain how the research design permits the inferences needed to examine the hypoth- esis or provide estimates in answer to the question.

In preparing your manuscript, begin the introduction on a new page, identifying it with the running head and the page number 3. Type the title of the manuscript in uppercase and lowercase letters centered at the top of the page, and then type the text. The remaining sections of the article follow each other without a break; do not start a new page when a new heading occurs. Each remaining manuscript page should also carry the running head and a page number.

2.06 Method The Method section describes in detail how the study was conducted, including con- ceptual and operational definitions of the variables used in the study. Different types of studies will rely on different methodologies; however, a complete description of the methods used enables the reader to evaluate the appropriateness of your meth- ods and the reliability and the validity of your results. It also permits experienced investigators to replicate the study. If your manuscript is an update of an ongoing or earlier study and the method has been published in detail elsewhere, you may refer the reader to that source and simply give a brief synopsis of the method in this sec- tion (see also section 1.10, regarding self-plagiarism). The following is an example of such a synopsis:

We present cross-sectional and 3-year longitudinal data from a study of adults aged 55 to 84. . . . The memory tasks were those used in our previous research

g (Zelinski et al., 1990; Zelinski, Gilewski, & Thompson, 1980).

If you are reporting on multiple experiments, see section 2.09.

Identify subsections. It is both conventional and expedient to divide the Method sec- t- tion into labeled subsections. These usually include a section with descriptions of the T participants or subjects and a section describing the procedures used in the study. The e latter section often includes description of (a) any experimental manipulations or inter- y ventions used and how they were delivered—for example, any mechanical apparatus

used to deliver them; (b) sampling procedures and sample size and precision; (c) meas- urement approaches (including the psychometric properties of the instruments used); and (d) the research design. If the design of the study is complex or the stimuli require

if detailed description, additional subsections or subheadings to divide the subsections may be warranted to help readers find specific information.

in these subsections the information essential to comprehend and replicate the study. Insufficient detail leaves the reader with questions; too much detail burdens

0 the reader with irrelevant information. Consider using appendices and/or a supplemen- tal website for more detailed information (see section 2.13).

Participant (subject) characteristics. Appropriate identification of research partici- pants is critical to the science and practice of psychology, particularly for generalizing the findings, making comparisons across replications, and using the evidence in research syntheses and secondary data analyses. If humans participated in the study, report the eligibility and exclusion criteria, including any restrictions based on demo- graphic characteristics.

Describe the sample adequately. Detail the sample's major demographic charac- teristics, such as age; sex; ethnic and/or racial group; level of education; socioeco- nomic, generational, or immigrant status; disability status; sexual orientation; gen- der identity; and language preference as well as important topic-specific characteristics (e.g., achievement level in studies of educational interventions). As a rule, describe the groups as specifically as possible, with particular emphasis on characteristics that may have bearing on the interpretation of results. Often, panic- ipant characteristics can be important for understanding the nature of the sample

MANUSCRIPT ELEMENTS

and the degree to which results can be generalized. For example, the following is a useful characterization of a sample:

The second group included 40 women between the ages of 20 and 30 years (M = 24.2, SD = 2.1), all of whom had emigrated from El Salvador; had at least 12 years of education; had been permanent residents of the United States for at least 10 years; and lived in Washington, DC.

To determine how far the data can be generalized, you may find it useful to identify subgroups:

The Asian sample included 30 Chinese and 45 Vietnamese persons.

or

Among the Latino and Hispanic American men, 20 were Mexican American and 20 were Puerto Rican.

Even when a characteristic is not used in analysis of the data, reporting it may give readers a more complete understanding of the sample and the generalizability of results and may prove useful in meta-analytic studies that incorporate the article's results.

When animals are used, report the genus, species, and strain number or other spe- cific identification, such as the name and location of the supplier and the stock desig- nation. Give the number of animals and the animals' sex, age, weight, and physiolog- ical condition.

Sampling procedures. Describe the procedures for selecting participants, including (a) the sampling method, if a systematic sampling plan was used; (b) the percentage of the sample approached that participated; and (c) the number of participants who selected themselves into the sample. Describe the settings and locations in which the data were collected as well as any agreements and payments made to participants, agreements with the institutional review board, ethical standards met, and safety monitoring procedures.

Sample size, power, and precision. Along with the description of subjects, give the intended size of the sample and number of individuals meant to be in each condition, if separate conditions were used. State whether the achieved sample differed in known ways from the target population. Conclusions and interpretations should not go beyond what the sample would warrant.

State how this intended sample size was determined (e.g., analysis of power or pre- cision). If interim analysis and stopping rules were used to modify the desired sample size, describe the methodology and results.

When applying inferential statistics, take seriously the statistical power considera- tions associated with the tests of hypotheses. Such considerations relate to the likeli- hood of correctly rejecting the tested hypotheses, given a particular alpha level, effect size, and sample size. In that regard, routinely provide evidence that the study has suf- ficient power to detect effects of substantive interest. Be similarly careful in discussing the role played by sample size in cases in which not rejecting the null hypothesis is desirable (i.e., when one wishes to argue that there are no differences), when testing various assumptions underlying the statistical model adopted (e.g., normality, homo- geneity of variance, homogeneity of regression), and in model fitting.

MANUSCRIPT STRUCTURE AND CONTENT

Alternatively, use calculations based on a chosen target precision (confidence inter- val width) to determine sample sizes. Use the resulting confidence intervals to justify conclusions concerning effect sizes (e.g., that some effect is negligibly small).

Measures and covariates. Include in the Method section information that provides def- initions of all primary and secondary outcome measures and covariates, including measures collected but not included in this report. Describe the methods used to col- lect data (e.g., written questionnaires, interviews, observations) as well as methods used to enhance the quality of the measurements (e.g., the training and reliability of assessors or the use of multiple observations). Provide information on instruments used, including their psychometric and biometric properties and evidence of cultural validity.

Research design. Specify the research design in the Method section. Were subjects placed into conditions that were manipulated, or were they observed naturalistically? Jf multiple conditions were created, how were participants assigned to conditions, through random assignment or some other selection mechanism? Was the study con- ducted as a between-subjects or a within-subject design?

Different research designs have different reporting needs associated with them. Information that should be reported for all studies that involve experimental manip- ulations or interventions is summarized in Table 2 of the Appendix, Module A: Reporting Standards for Studies With an Experimental Manipulation or Intervention (in Addition to Material Presented in Table 1) and Table 3 of the Appendix, Reporting Standards for Studies Using Random and Nonrandom Assignment of Participants to Experimental Groups. When reporting studies that are not of the manipulation or intervention variety (e.g., observational, natural history studies), provide sufficient description of the study procedures to allow the reader to fully comprehend the complexity of the study and to be prepared to conduct a near repli- cation of the study (see APA Publications and Communications Board Working Group on Journal Article Reporting Standards, 2008, for a discussion of the emer- gence of these standards).

Experimental manipulations or interventions. If interventions or experimental manipu- lations were used in the study, describe their specific content. Include the details of the interventions or manipulations intended for each study condition, including control groups (if any), and describe how and when interventions (experimental manipula- tions) were actually administered.

The description of manipulations or interventions should include several elements. Carefully describe the content of the intervention or specific experimental manipula- tions. Often, this will involve presenting a brief summary of instructions given to par- ticipants. If the instructions are unusual or compose the experimental manipulation, you may present them verbatim in an appendix or in an online supplemental archive. If the text is brief, you may present it in the body of the paper if it does not interfere with the readability of the report.

Describe the methods of manipulation and data acquisition. If a mechanical appara- tus was used to present stimulus materials or collect data, include in the description of procedures the apparatus model number and manufacturer (when important, as in neu- roimaging studies), its key settings or parameters (e.g., pulse settings), and its resolution (e.g., regarding stimulus delivery, recording precision). As with the description of the

MANUSCRIPT ELEMENTS

intervention or experimental manipulation, this material may be presented in the body of the paper, in an appendix, in an online supplemental archive, or as appropriate.

When relevant—such as, for example, in the delivery of clinical and educational interventions—the procedures should also contain a description of who delivered the intervention, including their level of professional training and their level of training in the specific intervention. Present the number of deliverers along with the mean, standard deviation, and range of number of individuals or units treated by each deliverer.

Provide information about (a) the setting where the intervention or manipulation was delivered, (b) the quantity and duration of exposure to the intervention or manipulation (i.e., how many sessions, episodes, or events were intended to be delivered and how long they were intended to last), (c) the time span taken for the delivery of the intervention or manipulation to each unit (e.g., would the manipulation delivery be complete in one ses- sion, or if participants returned for multiple sessions, how much time passed between the first and last session?), and (d) activities or incentives used to increase compliance.

When an instrument is translated into a language other than the language in which it was developed, describe the specific method of translation (e.g., back-translation, in which a text is translated into another language and then back into the first to ensure that it is equivalent enough that results can be compared).

Provide a description of how participants were grouped during data acquisition (i.e., was the manipulation or intervention administered individual by individual, in small groups, or in intact groupings such as classrooms?). Describe the smallest unit (e.g., indi- viduals, work groups, classes) that was analyzed to assess effects. If the unit used for sta- tistical analysis differed from the unit used to deliver the intervention or manipulation (i.e., was different from the unit of randomization), describe the analytic method used to account for this (e.g., adjusting the standard error estimates or using multilevel analysis).

2.07 Results In the Results section, summarize the collected data and the analysis performed on those data relevant to the discourse that is to follow. Report the data in sufficient detail to justify your conclusions. Mention all relevant results, including those that run counter to expectation; be sure to include small effect sizes (or statistically nonsignifi- cant findings) when theory predicts large (or statistically significant) ones. Do not hide uncomfortable results by omission. Do not include individual scores or raw data, with the exception, for example, of single-case designs or illustrative examples. In the spirit of data sharing (encouraged by APA and other professional associations and some- times required by funding agencies), raw data, including study characteristics and indi- vidual effect sizes used in a meta-analysis, can be made available on supplemental online archives. See section 2.13 for a detailed discussion of the use of supplemental online archives. Discussing the implications of the results should be reserved for presen- tation in the Discussion section.

Recruitment. Provide dates defining the periods of recruitment and follow-up and the primary sources of the potential subjects, where appropriate. If these dates differ by group, provide the values for each group.

Statistics and data analysis. Analysis of data and the reporting of the results of those analyses are fundamental aspects of the conduct of research. Accurate, unbiased, com-

od plete, and insightful reporting of the analytic treatment of data (be it quantitative or

y qualitative) must be a component of all research reports. Researchers in the field of

nal psychology use numerous approaches to the analysis of data, and no one approach is

th uniformly preferred as long as the method is appropriate to the research questions

e being asked and the nature of the data collected. The methods used must support their analytic burdens, including robustness to violations of the assumptions that underlie

ad them, and they must provide clear, unequivocal insights into the data.

Historically, researchers in psychology have relied heavily on null hypothesis sta- tistical significance testing (NHST) as a starting point for many (but not all) of its ana-

ivas lytic approaches. APA stresses that NHST is but a starting point and that additional reporting elements such as effect sizes, confidence intervals, and extensive description are needed to convey the most complete meaning of the results. The degree to which

'es- any journal emphasizes (or de-emphasizes) NHST is a decision of the individual edi-

the tor. However, complete reporting of all tested hypotheses and estimates of appropriate effect sizes and confidence intervals are the minimum expectations for all APA jour-

ich nals.2 The research scientist is always responsible for the accurate and responsible

in reporting of the results of research studies.

ire I Assume that your reader has a professional knowledge of statistical methods. Do

not review basic concepts and procedures or provide citations for the most commonly

e used statistical procedures. If, however, there is any question about the appropriateness

ajl of a particular statistical procedure, justify its use by clearly stating the evidence that

di- exists for the robustness of the procedure as applied.

ta- Similarly, missing data can have a detrimental effect on the legitimacy of the infer-

on ences drawn by statistical tests. For this reason, it is critical that the frequency or per-

to centages of missing data be reported along with any empirical evidence and/or theoret-

Ls) ical arguments for the causes of data that are missing. For example, data might be described as missing completely at random (as when values of the missing variable are not related to the probability that they are missing or to the value of any other vari- able in the data set); missing at random (as when the probability of missing a value on

on a variable is not related to the missing value itself but may be related to other com-

ail pletely observed variables in the data set); or not missing at random (as when the prob-

un ability of observing a given value for a variable is related to the missing value itself). It

fi- is also important to describe the methods for addressing missing data, if any were used

de (e.g., multiple imputation).

th When reporting the results of inferential statistical tests or when providing esti-

nt mates of parameters or effect sizes, include sufficient information to help the reader fully understand the analyses conducted and possible alternative explanations for the outcomes of those analyses. Because each analytic technique depends on different

al aspects of the data and assumptions, it is impossible to specify what constitutes a "suf-

al ficient set of statistics" for every analysis. However, such a set usually includes at least

n- the following: the per-cell sample sizes; the observed cell means (or frequencies of cases in each category for a categorical variable); and the cell standard deviations, or the pooled within-cell variance. In the case of multivariable analytic systems, such as mul-

2 Issues dealing with the controversy over the use of NHST and its alternatives are complex and outside the scope

of a publication manual. For those interested in this controversy, a discussion of these and related issues can be found in the article by Wilkinson and the Task Force on Statistical Inference (19991; 1-larlow, Mulaik, and Steiger's

se (1997) What If There Were No significance Tests? Kline's (2004) Beyond Significance Testing: Reforming Data Analysis Methods in Behavioral Research; and the article by Jones and Tukey (2000).

— MANUSCRIPT ELEMENTS tivariate analyses of variance, regression analyses, structural equation modeling analyses, and hierarchical linear modeling, the associated means, sample sizes, and variance—covariance (or correlation) matrix or matrices often represent a sufficient set of statistics. At times, the amount of information that constitutes a sufficient set of sta- tistics can be extensive; when this is the case, this information could be supplied in a supplementary data set or appendix (see section 2.13). For analyses based on very small samples (including single-case investigations), consider providing the complete set of raw data in a table or figure. Your work will more easily become a part of the cumulative knowledge of the field if you include enough statistical information to allow its inclusion in future meta-analyses.

For inferential statistical tests (e.g., t, F, and tests), include the obtained magni- tude or value of the test statistic, the degrees of freedom, the probability of obtaining a value as extreme as or more extreme than the one obtained (the exact p value), and the size and direction of the effect. When point estimates (e.g., sample means or regres- sion coefficients) are provided, always include an associated measure of variability (precision), with an indication of the specific measure used (e.g., the standard error).

The inclusion of confidence intervals (for estimates of parameters, for functions of parameters such as differences in means, and for effect sizes) can be an extremely effec- tive way of reporting results. Because confidence intervals combine information on location and precision and can often be directly used to infer significance levels, they are, in general, the best reporting strategy. The use of confidence intervals is therefore strongly recommended. As a rule, it is best to use a single confidence level, specified on an a priori basis (e.g., a 95% or 99% confidence interval), throughout the manuscript. Wherever possible, base discussion and interpretation of results on point and interval estimates.

For the reader to appreciate the magnitude or importance of a study's findings, it is almost always necessary to include some measure of effect size in the Results sec- tion.3 Whenever possible, provide a confidence interval for each effect size reported to indicate the precision of estimation of the effect size. Effect sizes may be expressed in the original units (e.g., the mean number of questions answered correctly; kg/month for a regression slope) and are often most easily understood when reported in original units. It can often be valuable to report an effect size not only in original units but also in some standardized or units-free unit (e.g., as a Cohen's d value) or a standardized regression weight. Multiple degree-of-freedom effect-size indicators are often less use- ful than effect-size indicators that decompose multiple degree-of-freedom tests into meaningful one degree-of-freedom effects—particularly when the latter are the results that inform the discussion. The general principle to be followed, however, is to provide the reader with enough information to assess the magnitude of the observed effect.

Ancillary analyses. Report any other analyses performed, including subgroup analyses and adjusted analyses, indicating those that were prespecified and those that were exploratory (though not necessarily in the level of detail of primary analyses). Consider putting the detailed results of these analyses on the supplemental online archive. Discuss the implications, if any, of the ancillary analyses for statistical error rates.

Participant flow. For experimental and quasi-experimental designs, there must be a description of the flow of participants (human, animal, or units such as classrooms or

hospital wards) through the study. Present the total number of units recruited into the

d study and the number of participants assigned to each group. Provide the number of participants who did not complete the experiment or crossed over to other conditions and explain why. Note the number of participants used in the primary analyses. number might differ from the number who completed the study because participants might not show up for or complete the final measurement.) The flowchart in the Appendix (Figure 1) provides a useful device for displaying the flow of participants through each stage of a study (see also Figures 5.3 and 5.4, pp. 154—155).

Intervention or manipulation fidelity. If interventions or experimental manipulations were used, provide evidence on whether they were delivered as intended. In basic experimental research, this might be the results of checks on the manipulation. In applied research, this might be, for example, records and observations of intervention delivery sessions and attendance records.

Baseline data. Be sure that baseline demographic and/or clinical characteristics of each

group are provided.

Statistics and data analysis. In studies reporting the results of experimental manipula- tions or interventions, clarify whether the analysis was by intent-to-treat. That is, were

n all participants assigned to conditions included in the data analysis regardless of whether they actually received the intervention, or were only participants who com- pleted the intervention satisfactorily included? Give a rationale for the choice.

Adverse events. If interventions were studied, detail all important adverse events (events with serious consequences) and/or side effects in each intervention group.

2.08 Discussion 0

n After presenting the results, you are in a position to evaluate and interpret their imph-

h cations, especially with respect to your original hypotheses. Here you will examine, interpret, and qualify the results and draw inferences and conclusions from them. Emphasize any theoretical or practical consequences of the results. (When the discus-

d sion is relatively brief and straightforward, some authors prefer to combine it with the Results section, creating a section called Results and Discussion.)

Open the Discussion section with a clear statement of the support or nonsupport for your original hypotheses, distinguished by primary and secondary hypotheses. If

e hypotheses were not supported, offer post hoc explanations. Similarities and differ- ences between your results and the work of others should be used to contextualize, confirm, and clarify your conclusions. Do not simply reformulate and repeat points already made; each new statement should contribute to your interpretation and to the reader's understanding of the problem.

Your interpretation of the results should take into account (a) sources of potential bias and other threats to internal validity, (b) the imprecision of measures, (c) the over- all number of tests or overlap among tests, (d) the effect sizes observed, and (e) other limitations or weaknesses of the study. If an intervention is involved, discuss whether it Was successful and the mechanism by which it was intended to work (causal path- Ways) and/or alternative mechanisms. Also, discuss barriers to implementing the inter- vention or manipulation as well as the fidelity with which the intervention or manip-

MANUSCRIPT ELEMENTS

ulation was implemented in the study, that is, any differences between the manipula- tion as planned and as implemented.

Acknowledge the limitations of your research, and address alternative explana- tions of the results. Discuss the generalizability, or external validity, of the findings. This critical analysis should take into account differences between the target popula- tion and the accessed sample. For interventions, discuss characteristics that make them more or less applicable to circumstances not included in the study, how and what out- comes were measured (relative to other measures that might have been used), the length of time to measurement (between the end of the intervention and the measure- ment of outcomes), incentives, compliance rates, and specific settings involved in the study as well as other contextual issues.

End the Discussion section with a reasoned and justifiable commentary on the importance of your findings. This concluding section may be brief or extensive provid- ed that it is tightly reasoned, self-contained, and not overstated. In this section, you might briefly return to a discussion of why the problem is important (as stated in the introduction); what larger issues, those that transcend the particulars of the subfield, might hinge on the findings; and what propositions are confirmed or disconfirmed by the extrapolation of these findings to such overarching issues.

You may also consider the following issues:

• What is the theoretical, clinical, or practical significance of the outcomes, and what is the basis for these interpretations? If the findings are valid and replicable, what real-life psychological phenomena might be explained or modeled by the results? Are applications warranted on the basis of this research?

• What problems remain unresolved or arise anew because of these findings?

The responses to these questions are the core of the contribution of your study and justify why readers both inside and outside your own specialty should attend to the findings. Your readers should receive clear, unambiguous, and direct answers.

2.09 Multiple Experiments If you are presenting several studies in one manuscript, make the rationale, logic, and method of each study clear to the reader. If appropriate, include for each study a short discussion of the results, or combine the discussion with the description of results (e.g., Results and Discussion). Always include a comprehensive general discussion of all the work after the last study. Report only conceptually linked studies in a single paper.

The arrangement of sections reflects the structure previously described. For exam- ple, label a series of experiments Experiment 1, Experiment 2, and so forth. They, organize the subsections and make referring to a specific experiment convenient for the' reader. The Method and Results sections (and the Discussion section, if a short discus- sion accompanies each study) appear under each study heading. (Refer to Figure pp. 54—56, for the form of a two-experiment paper.)

ses and meta-analyses are in the Appendix (Table 4, Meta-Analysis Reporting Standards [MARS]: Information Recommended for Inclusion in Manuscripts Reporting Meta-

The terms tue and issues should be familiar to researchers undertaking a meta-analysis and are ire- described in numerous texts. the

I

Note that easy access to electronic storage of information means that all of the ele- ments listed in the MARS guidelines need not appear in printed journal articles. The

tue online supplemental archives of journals can be used to store supplemental materials vid- associated with the articles that appear in print. This supplemental material might you include, for example, the list of citations to the research included in a meta-analysis and the the table giving descriptive information for each included study, especially when the eld, number of included studies is large. If the number of articles contributing studies to the I by meta-analysis is relatively small (e.g., about SO or fewer), they should appear in the ref-

erence list with an asterisk included to identify them. If the number of articles in the meta-analysis exceeds SO, then the references to the articles should be placed in a list

hat and in a supplemental online archive. If an article is mentioned in the text of a meta-

hat analytic article and the results reported in that article are included in the meta-analysis,

Are the article should be cited both in the reference list and in the supplemental materials.

2.11 References and References acknowledge the work of previous scholars and provide a reliable way to the locate it. References are used to document statements made about the literature, just

as data in the manuscript support interpretations and conclusions. The references cited in the manuscript do not need to be exhaustive but should be sufficient to support the need for your research and to ensure that readers can place it in the context of previ- ous research and theorizing.

The standard procedures for citation ensure that references are accurate, complete, and useful to investigators and readers. For detailed guidance on citing sources and preparing the reference list, consult Chapters 6 and 7.

Start the reference list on a new page. The word References should appear in upper- case and lowercase letters, centered. Double-space all reference entries. APA publishes references in a hanging indent format, meaning that the first line of each reference is set flush left and subsequent lines are indented.

2.12 Footnotes Footnotes are used to provide additional content or to acknowledge copyright permis- sion status.

Content footnotes. Content footnotes supplement or amplify substantive information in the text; they should not include complicated, irrelevant, or nonessential information. Because they can be distracting to readers, such footnotes should be included only if they strengthen the discussion. A content footnote should convey just one idea; if you find yourself creating paragraphs or displaying equations as you are writing a footnote,

H MANUSCRIPT ELEMENTS

your information. Another alternative is to indicate in a short footnote that the materi-

:I

then the main text or an appendix probably would be a more suitable place to present

al is available online as supplemental material. In most cases, an author integrates an article best by presenting important information in the text, not in a footnote.

Copyright permission. Copyright permission footnotes acknowledge the source of lengthy quotations, scale and test items, and figures and tables that have been reprint- ed or adapted. Authors must obtain permission to reproduce or adapt material from a copyrighted source. (See Chapter 8 for a discussion of what authors should know about permissions and copyright.)

A numbered footnote is generally used to provide source material for long quota- tions. For tables, the source material is provided in a table note (see section 5.16), and for figures, the source is credited at the end of the caption (see section 5.23). Use the wording below for copyright permission footnotes.

Type of source Copyright permission footnote

Journal From [or The data in column 1 are from] "Title of Article," by A. N. Author and C. 0. Author, year, lit/a of Journal, Volume, p. xx. Copyright [year] by the Name of Copyright Holder. Reprinted [or adapted] with permission.

Number all footnotes consecutively in the order in which they appear in the man- uscript with superscript Arabic numerals. Footnote numbers should be superscripted, like this,1 following any punctuation mark except a dash. A footnote number that appears with a dash—like this2_always precedes the dash. (The number falls inside a closing parenthesis if it applies only to matter within the parentheses, like this.3) Do not place footnote numbers in text headings. Subsequent references to a footnote are by parenthetical note:

the same results (see Footnote 3)

When using the footnote function in your word-processing program, place each content or copyright permission footnote at the bottom of the page on which it is dis- cussed. Footnotes may alternatively be placed in consecutive order on a separate page after the references. Be sure that the number of the footnote corresponds with the appropriate text discussion.

2.13 Appendices and Supplemental Materials Sometimes, material that supplements article content would be distracting or inappro- priate in the body of the manuscript. Material of this type can often be included in an appendix or in a supplemental materials section—the former being an element of the print version of the article, the latter being an online supplemental archive that the publisher of the archival source maintains.

i

MANUSCRIPT STRUCTURE AND CONTENT

ent Appendices. In general, an appendix is appropriate for materials that are relatively en- brief and that are easily presented in print format. Some examples of material suitable an for an appendix are (a) a list of stimulus materials (e.g., those used in psycholinguistic

research), (b) a detailed description of a complex piece of equipment, (c) a list of

of des that provided the source data for a meta-analysis but are not directly referred to

int- in any other way in an article, and (d) a detailed demographic description of subpop-

a ulations in the study and other detailed and/or complex reporting items suggested in the reporting standards section of this chapter.

If your manuscript has only one appendix, label it Appendix; if your manuscript

ta- F has more than one appendix, label each one with a capital letter (Appendix A,

Appendix B, etc.) in the order in which it is mentioned in the main text. Each appen-

the dix must have a title. In the text, refer to appendices by their labels:

produced the same results for both studies (see Appendices A and B for com- plete proofs).

Like the main text, an appendix may include headings and subheadings as well as tables, figures, and displayed equations. Number each appendix table and figure, and number displayed equations if necessary for later reference; precede the number with the letter of the appendix in which it is included (e.g., Table Al). In a sole appendix, which is not labeled with a letter, precede all tables, figures, and equation numbers with the letter A to distinguish them from those of the main text. All appendix tables and figures must be cited within the appendix and numbered in order of citation.

If one table constitutes an entire appendix, the centered appendix label and title serve in lieu of a table number and title. Generally, treat multiple tables as separate appendices. If multiple tables (but no text) are combined into one appendix, number the tables.

Begin each appendix on a separate page. Center the word Appendix and the iden- tifying capital letters (A, B, etc., in the order in which they are mentioned in text) at

lat the top of the page. Center the title of the appendix, and use uppercase and lowercase a letters. Begin the text of the appendix flush left, followed by indented paragraphs.

Supplemental materials. Web-based, online supplemental archives tend to be more appropriate for material that is more useful when available as a direct download as well as materials that are not easily presented in standard print format. Some exam- ples of materials suitable for inclusion in online supplemental archives are (a) lengthy computer code, (b) details of mathematical or computational models, (c) audio or video clips, (d) oversized tables, (e) detailed intervention protocols, (f) primary or supplementary data sets, (g) expanded methodology sections, and (h) color figures. Because this content may be useful to the field, APA and many other publishers make it possible to provide them to a wide audience by posting them on the web, with a link to the published article. These files (like an appendix) then become part of the primary journal record and cannot be augmented, altered, or deleted.

Materials for inclusion in supplemental online archives should be submitted in for- mats that will be widely accessible. The following multimedia formats are generally widely available to most users and are preferred:

• Text—ASCII, Word, PDF HTML • Tables__Excel, Word, HTML, XHTML, XML U Audio and Video—AW, MPG, Quicktime, RM, MP3, WAV

SAMPLE PAPERS

• Animation—GIF, JPEG, FlashlShockwave • Images—GIF, JPEG, TIFF

Less widely used file formats, including TeX, LaTeX, any client- or server-side scripting (e.g., Java, CCI), executable files, and software applications, are acceptable but may be of less use to the reader who does not have access to specialized programs. Many users refuse to deal with executable files or operate from systems that refuse to access them.

For APA journals, the link to online supplemental archives that appears in the pub- lished article leads readers to a landing page that includes a bibliographic citation, a link to the published article, and a context statement and link for each supplemental material file (see an example of a sample landing page at Supplemental materials should include enough information to make their contents interpretable when accompanied by the published text. For more information on sup- plemental materials, see Chapter 8.

Most journals make supplemental materials subject to peer review and require that they be submitted with the initial manuscript. Once accepted, the supplemental mate- rials will be posted with no further editing or polishing.

Include an appendix or supplemental materials only if they help readers to under- stand, evaluate, or replicate the study or theoretical argument being made. Be sure that all relevant ethical standards have been followed for appendices and supplemental materials, including copyright protection, accurate representation of data, and protec- tion of human subjects (e.g., content of video clips if human images).

Sample Papers These sample papers illustrate three kinds of manuscripts: one-experiment (Figure 2.1), two-experiment (Figure 2.2), and meta-analysis (Figure 2.3).

effects on detection time appeared stable in young and older adults.

The results described above suggeated that there was no influence of age on the

processing, given that no effects of valence were observed in otder sdults' deteclion speed. tn the

present study, older adults were equally fast to detect positive and negative information,

consistent wilh peior research that indicated that older adults often attead equally to positive and

negative slimuti (RosIer et al., 2005). Although the pattern of results for the young adults has

differed across studies—in the present study and in some past research, young adulls have shown

facilitated information (e.g., Anderson, 2005; Calvo & Lang, 2004; Canetie

et al., 2004; al., 2005; Nutntnenmaa et sI., 2006). whereas in other studies, young sdulls

have shownM advantage for negative information (e.g., Armony & Dolan, 2002; Hansen &

Hansen, Mogg. Bradley,de Bono, &Paintcr, Pratto & John, 1991; Reimann &

McNal,Iji, 1995; Wiltianta, Mathews, & MacLeod, 1996)—what it important to note is that the

oldet'adults detected holh positive and negative slimuli at equal rates. 'ntis equivalent deteclion

a( positive and negative informalion provides evidence that older adults display an advantage for

the detection of emotional information that is not vatence-apecinc.

Thus, although younger and older adulls exhibited eomewhat divergent patterns of

emotional detection on a task reliant on early, relatively automatic atages of ptocetaing, we

found uo evidence of an age-related positivity effect. The lack of a positivity focus in the older

adults is in keeping with the proposal (e.g., Maiher & Knight. 2006) thst the positivity effect

does not arise thtough automatic attentional influences. Rather, when Ihit effect is observed in

older adulta, it is likely due to age-related changes in emotion regulation goala that operate at

later stages ofprocessing (i.e.. during consciously controlled procesaing), once informalion has

been attended to and once the emotional nature of the atinsulua has been discerned.

Although we cannot conclusively say that the cutrent task relies atricily on automalic

Inhibitory Influences on Asychrony as a Cue for Auditory Segregation

Auditory grouping involves the formation of auditory objects from the round mixture

reaching the ears. The cues used to integrate or segregate these rounds and to form auditory

objects have been defined by several authors (e.g., Bregtnan, 1990) Darwin, 1997; Darwin &

Canyon, The key acoustic cues for segregating concutTent acouatic eletnenta are

differences in onset time (e.g., Dannenbring & Bregman, 1978; Rasch, t978) and hannonie

relations (e.g., Brunatrom & Roberts l998i Moore, Glasberg, & Peters, l98e. In an example of

the importance of onset time, Darwin (1984a, l984b) showed that increasing the level of a

harmonic near the first formant (Fl) frequency by adding a synchronous pure tone changes the

phonetic quatity of a vowel, However, when the added tone began a few hundred milliseconds

before the vowel, it was essentially removed from the vowel percept [seelion continuesi.

Writing Clearly and Concisely

T his chapter provides some general principles of expository writing and suggests ways to improve writing style. We focus first on the benefits of planning and choosing the best organizational structure to develop your argument. We next

describe some basic principles for writing with clarity and precision and for avoiding bias in language. Last, we demonstrate how correct grammar is the foundation of clear, effective, and persuasive communication.

Organization Before beginning to write, consider the best length and structure for the findings you wish to share. Ordering your thoughts logically, both at the paragraph and at the sen- tence levels, will strengthen the impact of your writing.

3.01 Length The optimal length of a manuscript is the number of pages needed to effectively com- municate the primary ideas of the study, review, or theoretical analysis. As a rule "less is more." Discursive writing often obscures an author's main points, and condensing long manuscripts often improves them. If a paper is too long, shorten it by stating points clearly and directly, confining the discussion to the specific problem under inves- tigation, deleting or combining data displays, eliminating repetition across sections, and writing in the active voice. At times, a paper may need to be divided into two or more papers, each with a more specific focus (however, see section 1.09 on piecemeal publication). Journals differ in average length of articles published. It is generally wise to be consistent with the usual practices of the journal to which you are submitting Your paper.

ORGANIZATION

3.02 Organizing a Manuscript With Headings In scientific writing, sound organizational structure is the key to clear, precise, and log- ical communication. This includes the use of headings to effectively organize ideas within a study as well as seriation to highlight important items within sections. Concise headings help the reader anticipate key points and track the development of your argu- ment.

Readers familiar with earlier editions of the Publication Manual will note that we have changed and simplified the heading styles in this edition. This change was moti- vated by the desire to make planning a less complicated process for the writer and to make articles more accessible for those reading them in electronic formats.

Levels of heading establish the hierarchy of sections via format or appearance. All topics of equal importance have the same level of heading throughout a manuscript. For example, in a multiexperiment paper, the headings for the Method and Results sec- tions in Experiment 1 should be the same level as the headings for the Method and Results sections in Experiment 2.

Avoid having only one subsection heading and subsection within a section, just as you would in an outline. Use at least two subsection headings within any given section, or use none (e.g., in an outline, you could divide a section numbered I into a minimum of A and B sections; just an A section could not stand alone).

3.03 Levels of Heading The heading style recommended by APA consists of five possible formatting arrange- ments, according to the number of levels of subordination. Each heading level is num- bered (see Table 3.1).

Regardless of the number of levels of subheading within a section, the heading struc- ture for all sections follows the same top-down progression. Each section starts with the

highest level of heading, even if one section may have fewer levels of subheading than another section. For example, the Method and Results sections of a paper may each have

two levels of subheading, and the Discussion section may have only one level of subhead-

:as ing. There would then be three levels of heading for the paper overall: the section head:

ings (Method. Results, and Discussion) and the two levels of subheading, as follows:

Limitations of the Present Study Conclusions and Future Prospects

The introduction to a manuscript does not carry a heading that labels it as the he introduction. (The first part of a manuscript is assumed to be the introduction.)

Do not label headings with numbers or letters. (The sections and headings in the Publication Manual are numbered only to permit indexing and cross-referencing.) The number of levels of heading needed for your article will depend on its length and com- plexity. If only one level of heading is needed, use Level 1; for a paper with two levels of

heading, use Levels 1 and 2; if three levels are needed, use Levels 1, 2, and 3; and so forth.

3.04 Seriation Just as the heading structure alerts readers to the order of ideas within the paper, seri- ation helps the reader understand the organization of key points within sections, para-

graphs, and sentences. In any series, all items should be syntactically and conceptual-

ly parallel (see section 3.23). Separate paragraphs in a series, such as itemized conclusions or steps in a proce-

• dure, are identified by an Arabic numeral followed by a period but not enclosed in or followed by parentheses. Separate sentences in a series are also identified by an Arabic

numeral followed by a period; the first word is capitalized, and the sentence ends with

a period or correct punctuation.

Using the learned helplessness theory, we predicted that the depressed and

nondepressed participants would make the following judgments of control

ORGANIZATION

1. Individuals who . . [paragraph continuesj.

2. Nondepressed persons exposed to. . . [paragraph continues].

3. Depressed persons exposed to. . . [paragraph continues].

4. Depressed and nondepressed participants in the no-noise groups. . . [paragraph continues].

The use of "numbered lists" may connote an unwanted or unwarranted ordinal position (e.g. chronology, importance, priority) among the items. If you wish to achieve the same effect without the implication of ordinality, items in the series should be identified by bullets. Symbols such as small squares, circles, and so forth, may be used in creating a bulleted list. At the time that an article accepted for publication is typeset, the bullet notation will be changed to the style used by that journal.

• Individuals who . . . [paragraph continues].

• Nondepressed persons exposed to. . . [paragraph continues]. • Depressed persons exposed to. . . [paragraph continues].

• Depressed and nondepressed participants in the no-noise groups . . . [para- graph continues].

Within a paragraph or sentence, identify elements in a series by lowercase letters in parentheses.

The participant's three choices were Ca) working with another participant, (b) working with a team, and Cc) working alone.

Within a sentence, use commas to separate three or more elements that do not have internal commas; use semicolons to separate three or more elements that have internal commas.

We tested three groups: Ca) low scorers, who scored fewer than 20 points; (b) moderate scorers, who scored between 20 and 50 points; and Cc) high scorers, who scored more than 50 points.

Alternatively, you may use bulleted lists within a sentence to separate three or more elements. In these instances, capitalize and punctuate the list as if it were a complete sentence.

In accordance with this theory, these relations should be marked by

• equity, social justice, and equal opportunity;

• sensitivity to individual differences and promotion of a goodness-of-fit between individually different people and contexts;

• affirmative actions to correct ontogenetic or historical inequities in person—

WRITING CLEARLY AND CONCISELY

• efforts to recognize and celebrate diversity; and

• promotion of universal participation in civic life, and hence democracy (Lerner, Balsano, Banik, & Naudeau, 2005, p. 45).

Writing Style nat The prime objective of scientific reporting is clear communication. You can achieve to this by presenting ideas in an orderly manner and by expressing yourself smoothly and

ild precisely. Establishing a tone that conveys the essential points of your study in an inter-

be esting manner wilt engage readers and communicate your ideas more effectively.

is

3.05 Continuity in Presentation of Ideas Readers will better understand your ideas if you aim for continuity in words, concepts, and thematic development from the opening statement to the conclusion. Continuity can be achieved in several ways. For instance, punctuation marks contribute to conti- nuity by showing relationships between ideas. They cue the reader to the pauses, inflec- tions, subordination, and pacing normally heard in speech. Use the full range of punc- tuation aids available: Neither overuse nor underuse one type of punctuation, such as commas or dashes. Overuse may annoy the reader; underuse may confuse. Instead, use punctuation to support meaning.

Another way to achieve continuity is through the use of transitional words. These words help maintain the flow of thought, especially when the material is complex or abstract. A pronoun that refers to a noun in the preceding sentence not only serves as a transition but also avoids repetition. Be sure the referent is obvious. Other transition devices are time links (then, next, after, while, since), cause—effect links (therefore, con- sequently, as a result), addition links (in addition, moreover, furthermore, similarly), and contrast links (but, conversely, nevertheless, however, although).

3.06 Smoothness of Expression Scientific prose and creative writing serve different purposes. Devices that are often found in creative writing—for example, setting up ambiguity; inserting the unexpected; omitting the expected; and suddenly shifting the topic, tense, or person—can confuse or disturb readers of scientific prose. Therefore, try to avoid these devices and aim for clear and logical communication.

Because you have been so close to your material, you may not immediately see cer- tain problems, especially contradictions the reader may infer. A reading by a colleague may uncover such problems. You can usually catch omissions, irrelevancies, and abruptness by putting the manuscript aside and rereading it later. Reading the paper aloud can make flaws more apparent. (See also section 3.11.)

If, on later reading, you find that your writing is abrupt, introducing more transi- tion devices may be helpful. You may have abandoned an argument or theme prema- turely; if so, you need to amplify the discussion.

Abruptness may result from sudden, unnecessary shifts in verb tense within the same paragraph or in adjacent paragraphs. By using verb tenses consistently, you can help ensure smooth expression. Past tense (e.g., "Smith showed") or present perfect

WRITING STYLE

tense (e.g., "researchers have shown") is appropriate for the literature review and the description of the procedure if the discussion is of past events. Stay within the chosen tense. Use past tense (e.g., "anxiety decreased significantly") to describe the results. Use the present tense (e.g., "the results of Experiment 2 indicate") to discuss implica- tions of the results and to present the conclusions. By reporting conclusions in the pres-ent tense, you allow readers to join you in deliberating the matter at hand. (See section 3.19 for details on the use of verb tense.)

Noun strings, meaning several nouns used one after another to modify a finalnoun, create another form of abruptness. The reader is sometimes forced to stop todetermine how the words relate to one another. Skillful hyphenation can clarify therelationships between words, but often the best approach is to untangle the string. For example, consider the following string:

commonly used investigative expanded issue control question technique

This is dense prose to the reader knowledgeable about studies on lie detection—and gibberish to a reader unfamiliar with such studies. Possible ways to untangle the string are as follows:

• a control-question technique that is commonly used to expand issues in investigations

• an expanded-issue control-question technique that is commonly used in investigations

• a common technique of using control questions to investigate expanded issues • a common investigative technique of using expanded issues in control

questions

One approach to untangling noun strings is to move the last word to the beginningof the string and fill in with verbs and prepositions. For example, early childhood thought disorder misdiagnosis might be rearranged to read misdiagnosjs of thoughtdisorders in early childhood.

Many writers strive to achieve smooth expression by using synonyms or near-synonyms to avoid repeating a term. The intention is commendable, but by usingsynonyms you may unintentionally suggest a subtle difference. Therefor; choose syn-onyms with care. The discreet use of pronouns can often relieve the monotonous rep- Ietition of a term without introducing ambiguity.

3.07 Tone Although scientific writing differs in form from literary writing, it need not lack styleor be dull. In describing your research, present the ideas and findings directly but aimfor an interesting and compelling style and a tone that reflects your involvement withthe problem.

Scientific writing often contrasts the positions of different researchers. Differences should be presented in a professional, noncombative manner. For example, "Fong and Nisbett did not address is acceptable, whereas "Fong and Nisbett completely overlooked . . ." is not.

L

WRITING CLEARLY AND CONCISELY

One effective way to achieve the right tone is to imagine a specific reader you are intending to reach and to write in a way that will educate and persuade that individual. Envisioning a person familiar to you may make this technique more effective. You may wish to write, for example, to a researcher in a related field who is trying to keep abreast of the literature but is not familiar with jargon or insider perspectives. What would facilitate his or her understanding of and appreciation for the importance of your work?

3.08 Economy of Expression Say only what needs to be said. The author who is frugal with words not only writes a more readable manuscript but also increases the chances that the manuscript will be accepted for publication. The number of printed pages a journal can publish is limited,

and editors therefore often request that authors shorten submitted papers. You can

of the passive voice, circumlocution, and clumsy prose. Weed out overly detailed descriptions of apparatus, participants, or procedures (beyond those called for in the reporting standards; see Chapter 2); elaborations of the obvious; and irrelevant obser- vations or asides. Materials such as these may be placed, when appropriate, in an online supplemental archive (see sections 2.13 and 8.03 for further details).

Short words and short sentences are easier to comprehend than are long ones. A long technical term, however, may be more precise than several short words, and tech- nical terms are inseparable from scientific reporting. Yet the technical terminology in a paper should be readily understood by individuals throughout each discipline. An article that depends on terminology familiar to only a few specialists does not suffi- ciently contribute to the literature.

Wordiness. Wordiness can also impede the ready grasp of ideas. Change based on the fact that to because, at the present time to now, and for the purpose of to simply for or to. Use this study instead of the present study when the context is cleat Change there were several students who completed to several students completed. Unconstrained wordiness lapses into embellishment and flowery writing, which are clearly inappropriate in scientific style.

Redundancy. Writers often use redundant language in an effort to be emphatic. Use no more words than are necessary to convey your meaning.

In the following examples, the italicized words are redundant and should be omitted:

WRITING STYLE

Unit length. Although writing only in short, simple sentences produces choppy and bor- ing prose, writing exclusively in long, involved sentences results in difficult, sometimes incomprehensible material. Varied sentence length helps readers maintain interest and comprehension. When involved concepts require long sentences, the components should proceed logically. Direct, declarative sentences with simple, common words are usually best.

Similar cautions apply to paragraph length. Single-sentence paragraphs are abrupt. Paragraphs that are too long are likely to lose the reader's attention. A new paragraph provides a pause for the reader—a chance to assimilate one step in the conceptual development before beginning another. If a paragraph runs longer than one double- spaced manuscript page, you may lose your readers. Look for a logical place to break a long paragraph, or reorganize the material.

Word choice. Make certain that every word means exactly what you intend it to mean. In informal style, for example, feel broadly substitutes for think or believe, but in sci- entific style such latitude is not acceptable. A similar example is that like is often used when such as is meant:

Correct:

Articles by psychologists such as Skinner and Watson.

Correct:

Like Watson, Skinner believed.

Incorrect:

Articles by psychologists like Skinner and Watson.

Colloquial expressions. Avoid colloquial expressions (e.g, write up for report), which diffuse meaning. Approximations of quantity (e.g., quite a large part, practically all, or very few) are interpreted differently by different readers or in different contexts. Approximations weaken statements, especially those describing empirical observations. Jargon. Jargon is the continuous use of a technical vocabulary, even in places where that vocabulary is not relevant. Jargon is also the substitution of a euphemistic phrase for a familiar term (e.g., monetarily felt scarcity for poverty), and you should scrupu- lously avoid using such jargon. Federal bureaucratic jargon has had the greatest pub- licity, but scientific jargon also grates on the reader, encumbers the communication of information, and wastes space.

Pronouns. Pronouns confuse readers unless the referent for each pronoun is obvious; readers should not have to search previous text to determine the meaning of the term. Pronouns such as this, that, these, and those can be troublesome when they refer to something or someone in a previous sentence. Eliminate ambiguity by writing, for example, this test, that trial, these participants, and those reports (see also section 3.20).

Comparisons. Ambiguous or illogical comparisons result from omission of key verbs or from nonparallel structure. Consider, for example, "Ten-year-olds were more like- ly

to play with age peers than 8-year-olds." Does this sentence mean that 1O-year-olds were more likely than 8-year olds to play with age peers> Or does it mean that 10

WRITING CLEARLY AND CONCISELY

year-olds were more likely to play with age peers and less likely to play with 8-year- es Old5? An illogical comparison occurs when parallelism is overlooked for the sake of id brevity, as in "Her salary was lower than a convenience store clerk." Thoughtful Lts

attention to good sentence structure and word choice reduces the chance of this kind

re of ambiguity.

Attribution. Inappropriately or illogically attributing action in an effort to be objective can be misleading. Examples of undesirable attribution include use of the third person, anthropomorphism, and use of the editorial we.

Thirdperson. To avoid ambiguity, use a personal pronoun rather than the third per- son when describing steps taken in your experiment.

Correct:

We reviewed the literature.

Incorrect:

The authors reviewed the literature.

Ant hropomorphism. Do not attribute human characteristics to animals or to inani- mate sources.

Correct:

Pairs of rats (cage mates) were allowed to forage together.

Incorrect:

Rat couples (cage mates) were allowed to forage together.

Correct:

The staff for the community program was persuaded to allow five of the observers to become tutors.

Incorrect:

An experiment cannot attempt to demonstrate, control unwanted variables, or interpret findings, nor can tables or figures compare (all of these can, however, show or indicate). Use a pronoun or an appropriate noun as the subject of these verbs. I or we (meaning the author or authors) can replace the experiment.

Editorial we. For clarity, restrict your use of we to refer only to yourself and your coauthors (use I if you are the sole author of the paper). Broader uses of we may leave your readers wondering to whom you are referring; instead, substitute an appropriate noun or clarify your usage:

Researchers usually classify birdsong on the basis of frequency and temporal structure of the elements.

3.10 Linguistic Devices Devices that attract attention to words, sounds, or other embellishments instead of to ideas are inappropriate in scientific writing. Avoid heavy alliteration, rhyming, poetic expressions, and clichés. Use metaphors sparingly; although they can help simplify complicated ideas, metaphors can be distracting. Avoid mixed metaphors (e.g., a the- ory representing one branch of a growing body of evidence) and words with surplus or unintended meaning (e.g., cop for police officer), which may distract if not actual- ly mislead the reader. Use figurative expressions with restraint and colorful expressions with care; these expressions can sound strained or forced.

3.11 Strategies to Improve Writing Style

Reducing Bias in Language

Authors use various strategies in putting their thoughts on paper. The fit between author and strategy is more important than the particular strategy used. Three approaches to achieving professional and effective communication are (a) writing from an out- line; (b) putting aside the first draft, then rereading it later; and (c) asking a colleague to review and critique the draft for you.

Writing from an outline helps preserve the logic of the research itself. An outline identifies main ideas, defines subordinate ideas, helps you discipline your writing and avoid tangential excursions, and helps you notice omissions. In an outline, you can also identify the subheadings that will be used in the article itself.

Rereading your own copy after setting it aside for a few days permits a fresh approach. Reading the paper aloud enables you not only to see faults that you overlooked on the previous reading but also to hear them. When these problems are corrected, give a polished copy to a colleague—preferably a person who has published in a related field but who is not familiar with your own work—for a critical review. Even better, get critiques from two colleagues, and you will have a trial run of a journal's review process.

These strategies, particularly the latter, may require you to invest more time in a manuscript than you had anticipated. The results of these strategies, however, may be greater accuracy and thoroughness and clearer communication.

Scientific writing must be free of implied or irrelevant evaluation of the group or groups being studied. As an organization, APA is committed both to science and to the fair treatment of individuals and groups, and this policy requires that authors who write for APA publications avoid perpetuating demeaning attitudes and biased

WRITING CLEARLY AND CONCISELY

assumptions about people in their writing. Constructions that might imply bias against persons on the basis of gender, sexual orientation, racial or ethnic group, disability, or age are unacceptable.

Long-standing cultural practice can exert a powerful influence over even the most conscientious author. Just as you have learned to check what you write for spelling, grammar, and wordiness, practice rereading your work for bias. Another suggestion is to ask people from targeted groups to read and comment on your material.

What follows is a set of guidelines and discussions of specific issues that affect par- ticular groups. These are not rigid rules. You may find that some attempts to follow the guidelines result in wordiness or clumsy prose. As always, good judgment is required. If your writing reflects respect for your participants and your readers and if you write

to with appropriate specificity and precision, you will be contributing to the goal of accu- tic rate, unbiased communication. Specific examples for each guideline are given in

the Guidelines for Unbiased Language, which can be found on the APA Style website (www.apastyle.org).

General Guidelines for Reducing Bias Guideline 1: Describe at the Appropriate Level of Specificity

Precision is essential in scientific writing; when you refer to a person or persons, choose words that are accurate, clear, and free from bias. The appropriate degree of specifici- ty depends on the research question and the present state of knowledge in the field of study. When in doubt, be more specific rather than less, because it is easier to aggre- gate published data than to disaggregate them. For example, using man to refer to all human beings is simply not as accurate as the phrase women and men. To describe age groups, give a specific age range ("ages 65—83 years") instead of a broad category ("over 65 years"; see Schaie, 1993). When describing racial and ethnic groups, be appropriately specific and sensitive to issues of labeling. For example, instead of describing participants as Asian American or Hispanic American, it may be helpful to describe them by their nation or region of origin (e.g., Chinese Americans, Mexican Americans). If you are discussing sexual orientation, realize that some people interpret gay as referring to men and women, whereas others interpret the term as referring only to men (the terms gay men and lesbians currently are preferred).

Broad clinical terms such as borderline and at risk are loaded with innuendo unless properly explained. Specify the diagnosis that is borderline (e.g., "people with border- line personality disorder"). Identify the risk and the people it involves (e.g., "children at risk for early school dropout").

Gender is cultural and is the term to use when referring to women and men as social groups. Sex is biological; use it when the biological distinction is predominant. Note that the word sex can be confused with sexual behavior. Gender helps keep meaning unambiguous, as in the following example: "In accounting for attitudes toward the bill, sexual orientation rather than gender accounted for most of the variance. Most gay men and lesbians were for the proposal; most heterosexual men and women were against it."

Part of writing without bias is recognizing that differences should be mentioned only when relevant. Marital status, sexual orientation, racial and ethnic identity, or the fact that a person has a disability should not be mentioned gratuitously.

GUIDELINES FOR REDUCING BIAS

Guideline 2: Be Sensitive to Labels Respect people's preferences; call people what they prefer to be called. Accept that preferences change with time and that individuals within groups often disagree about the designations they prefer. Make an effort to determine what is appropriate for your situation; you may need to ask your participants which designations they prefer, par- ticularly when preferred designations are being debated within groups.

Avoid labeling people when possible. A common occurrence in scientific writing is that participants in a study tend to lose their individuality; they are broadly categorized as objects (noun forms such as the gays and the elderly) or, particularly in descriptions of people with disabilities, are equated with their conditions—the amnesiacs, the depressives, the schizophrenics, the LDs, for example. One solution is to use adjectival forms (e.g., "gay men," "older adults," "amnesic patients"). Another is to "put the person first," followed by a descriptive phrase (e.g., "people diagnosed with schizophrenia"). Note that

F the latter solution currently is preferred when describing people with disabilities. When you need to mention several groups in a sentence or paragraph, such as

when reporting results, do your best to balance sensitivity, clarity, and parsimony. For example, it may be cumbersome to repeat phrases such as "person with

_______."

IfF you provide operational definitions of groups early in your paper (e.g., "Participants scoring a minimum of X on the X scale constituted the high verbal group, and those scoring below X constituted the low verbal group"), it is scientifically informative and concise to describe participants thereafter in terms of the measures used to classify them (e.g., ". . . the contrast for the high verbal group was statistically significant, p = .043"), provided the terms are inoffensive. A label should not be used in any form that is perceived as pejorative, if such a perception is possible, you need to find more neu

F

tral terms. Fot example, the demented is not repaired by changing it to demented grbup, but dementia group would be acceptable. Abbreviations or series labels for groups usually sacrifice clarity and may offend: LDs or LD group to describe people with specific learning difficulties is offensive; HVAs for "high verbal ability group" is difficult td decipher. Group A is not offensive, but it is not descriptive either.

Recognize the difference case, which is an occurrence of a disorder or ill- ness, and patient, which is a person affected by the disorder or illness and receiving a docto?s care. "Manic—depressive cases were treated" is problematic; revise to "The patients with bipolar disorders were treated."

Bias may be promoted when the writer uses one group (often the writer's own group) as the standard against which others are judged, for example, citizens of the United States. In some contexts, the term culturally deprived may imply that one cul- ture the universally accepted standard. The unparallel nouns in the phrase man and: wife mdy inappropriately prompt the reader to evaluate the roles of the individuals (ke., the woman is defined only in terms of her relationship to the man) and the motives of the author. By contrast, the phrases husband and wife and man and woman are parallel. Usage of normal may prompt the reader to make the comparison with:

H abnormal, thus stigmatizing individuals with differences. For example, contrasting les- bians with "the general public" or with "normal women" portrays lesbians as margin-

F

al to society. More appropriate comparison groups might be heterosexual women, het-. H erosexual women and men, or gay men.

Also be aware of how order of presentation of social groups can imply that the first-mentioned group is the norm or standard and that later mentioned groups are-

WRITING CLEARLY AND CONCISELY

deviant. Thus the phrases men and women and White Americans and racial minorities

•hat subtly reflect the perceived dominance of men and Whites over other groups. Similarly,

out when presenting group data, consider how placing socially dominant groups such as

our men and Whites on the left side of graphs and/or top of tables may also imply that

ar- these groups are the universal standard (Hegarty & Buechel, 2006). Avoid a consistent pattern of presenting information about socially dominant groups first.

is

las Guideline 3: Acknowledge Participation

Write about the people in your study in a way that acknowledges their participation but is also consistent with the traditions of the field in which you are working. Thus, although descriptive terms such as college students, children, or respondents provide precise information about the individuals taking part in a research project, the more general terms participants and subjects are also in common usage. Indeed, for more than

as 100 years the term subjects has been used within experimental psychology as a general

or starting point for describing a sample, and its use is appropriate. Subjects and sample

If are customary when discussing certain established statistical terms (e.g., within-subject

its and between-subjects design). Further, the passive voice suggests individuals are acted on instead of being actors ("the students completed the survey" is preferable to "the stu-

nd dents were given the survey" or "the survey was administered to the students"). "The subjects completed the trial" or "we collected data from the participants" is preferable

= to "the participants were run." Consider avoiding terms such as patient management

tat and patient placement when appropriate. In most cases, it is the treatment, not patients,

u- that is managed; some alternatives are coordination of care, supportive services, and

ed assistance. Also avoid the term failed, as in "eight participants failed to complete the

or Rorschach and the MMPI," because it can imply a personal shortcoming instead of a

ile research result; did not is a more neutral choice (Knatterud, 1991).

Reducing Bias by Topic 3.12 Gender Remember that gender refers to role, not biological sex, and is cultural. Avoid ambi-

I guity in sex identity or gender role by choosing nouns, pronouns, and adjectives that specifically describe your participants. Sexist bias can occur when pronouns are used carelessly, as when the masculine pronoun he is used to refer to both sexes or when the masculine or feminine pronoun is used exclusively to define roles by sex (e.g., "the nurse . . . she"). The use of man as a generic noun or as an ending for an occupation- al title (e.g., policeman instead of police officer) can be ambiguous and may imply incorrectly that all persons in the group are male. Be clear about whether you mean one sex or both sexes.

There are many alternatives to the generic he (see the Guidelines for Unbiased Language at www.apastyle.org), including rephrasing (e.g., from "When an individual Conducts this kind of self appraisal, he is a much stronger person" to "When an individ-

____

REDUCiNG BIAS BY TOPIC

ual conducts this kind of self-appraisal, that person is much stronger" or "This kind of self-appraisal makes an individual much stronger"), using plural nouns or plural pro- nouns (e.g., from "A therapist who is too much like his client can lose his objectivity" to "Therapists who are too much like their clients can lose their objectivity"), replacing the pronoun with an article (e.g., from "A researcher must apply for his grant by September 1" to "A researcher must apply for the grant by September 1"), and drop- ping the pronoun (e.g., from "The researcher must avoid letting his own biases and expectations influence the interpretation of the results" to "The researcher must avoid letting biases and expectations influence the interpretation of the results"). Replacing he with he or she or she or he should be done sparingly because the repetition can become tiresome. Combination forms such as he/she or (s)he are awkward and distracting. Alternating between he and she also may be distracting and is not ideal; doing so implies that he or she can in fact be generic, which is not the case. Use of either pronoun unavoidably suggests that specific gender to the reader. Avoid referring to one sex as the opposite sex: an appropriate wording is the other sex. The term opposite sex implies strong differences between the two sexes; however, in fact, there are more similarities than differences between the two sexes (e.g., Hyde, 2005).

The adjective transgender refers to persons whose gender identity or gender expres- sion differs from their sex at birth; trans gender should not be used as a noun (National Lesbian & Gay Journalists Association, 2005). The word transsexual refers to transgen. der persons who live or desire to live full time as members of the sex other than their sex at birth, many of whom wish to make their bodies as congruent as possible with their preferred sex through surgery and hormonal treatment (American Psychiatric Association, 2000; Meyer et al., 2001). Transsexual can be used as a noun or as an adjec- tive. The terms female-to-male transgender person, male-to-female transgender person, female-to-male transsexual, and male-to-female transsexual represent accepted usage (Gay & Lesbian Alliance Against Defamation, 2007). Transsexuals undergo sex reassign- ment, a term that is preferable to sex change. Cross-dresser is preferable to transvestite.

Refer to a transgender person using words (proper nouns, pronouns, etc.) appro- priate to the person's gender identity or gender expression, regardless of birth sex. For example, use the pronouns he, him, or his in reference to a female-to-male transgen- der person. If gender identity or gender expression is ambiguous or variable, it may be best to avoid pronouns, as discussed earlier in this section (for more detailed informa- tion, see www.apastyle.org).

3.13 Sexual Orientation Sexual orientation refers to an enduring pattern of attraction, behavior, emotion, identi-

and social contacts. The term sexual orientation should be used rather than sexual preference. For a person having a bisexual orientation, the orientation is not chosen even though the sex of the partner may be a choice. For more information, see Guidelines for Psychotherapy With Lesbian, Gay, and Bisexual Clients (APA Committee on Lesbian, Gay, and Bisexual Concerns Joint Task Force on Guidelines for Psychotherapy With Lesbian, Gay, and Bisexual Clients, 2000; see also www.apastyle.org).

The terms lesbians, gay men, bisexual men, and bisexual women are preferable to homosexual when one is referring to people who identify this way. Lesbian, gay,

and to and communities that have devel- among people who share those identities. As such, the terms lesbians, gay men,

WRITING CLEARLY AND CONCISELY

.d of and bisexual individuals are more accurate than homosexual. Furthermore, the term pro- homosexuality has been and continues to be associated with negative stereotypes, ity" pathology, and the reduction of people's identities to their sexual behavior. Gay can be cing interpreted broadly, to include men and women, or more narrowly, to include only men:

by

3.14 Racial and Ethnic Identity mid preferences for terms referring to racial and ethnic groups change often. One reason for

he this is simply personal preference; preferred designations are as varied as the people they me name. Another reason is that over time, designations can become dated and sometimes

ing. negative. Authors are reminded of the two basic guidelines of specificity and sensitivity. lies In keeping with Guideline 2, use commonly accepted designations (e.g., Census cate- )un gories) while being sensitive to participants' preferred designation. For example, some the North American people of African ancestry prefer Black and others prefer African lies American; both terms currently are acceptable. On the other hand, Negro and Afro- ties American have become dated; therefore, usage of these terms generally is inappropriate.

In keeping with Guideline 1, precision is important in the description of your sample (see section 2.06); in general, use the more specific rather than the less specific term.

nal Language that essentializes or reifies race is strongly discouraged and is generally con-

en- sidered inappropriate. For example, phrases such as the Black race and the White race are

;ex essentialist in nature, portray human groups monolithically, and often serve to perpetuate

Leir stereotypes. Authors sometimes use the word minority as a proxy for non-white racial

•ric and ethnic groups. This usage may be viewed pejoratively because minority is usually

cc- equated with being less than, oppressed, and deficient in comparison with the majority (i.e., Whites). Use a modifier (such as ethnic or racial) when using the word minority. When possible, use the actual name of the group or groups to which you are referring.

'ii- Racial and ethnic groups are designated by proper nouns and are capitalized. Therefore, use Black and White instead of black and white (the use of colors to refer to other human groups currently is considered pejorative and should not be used).

or Unparallel designations (e.g., African Americans and Whites; Asian Americans and Black Americans) should be avoided because one group is described by color while the other group is described by cultural heritage. For modifiers, do not use hyphens in multiword names, even if the names act as unit modifiers (e.g., Asian American participants).

Designations for some ethnic groups are described next. These groups frequently are included in studies published in APA journals. These examples are far from exhaus- tive but illustrate some of the complexities of naming (see the Guidelines for Unbiased Language at www.apastyle.org). Depending on where a person is from, individuals may prefer to be called Hispanic, Latino, Chicano, or some other designation; Hispanic is not necessarily an all-encompassing term, and authors should consult with their partic- ipants. In general, naming a nation or region of origin is helpful (e.g., Cuban, Salvadoran, or Guatemalan is more specific than Central American or Hispanic).

American Indian, Native American, and Native North American are all accepted terms for referring to indigenous peoples of North America. When referring to groups Including Hawaiians and Samoans, you may use the broader designation Native Americans. The indigenous peoples of Canada may be referred to as First Nations or limit people. There are close to 450 Native North American groups, and authors are encouraged to name the participants' specific groups, recognizing that some groups prefer the name for their group in their native language (e.g., Dine instead of Navajo, Tohono O'odham instead of Papago).

REDUCING BIAS BY TOPIC

The term Asian or Asian American is preferred to the older term Oriental. It is gen- erally useful to specify the name of the Asian subgroup: Chinese, Vietnamese, Korean, Pakistani, and so on. People of Middle Eastern descent may also be identified by nation of origin: Iraqi, Lebanese, and so forth.

3.15 Disabilities The overall principle for "nonhandicapping" language is to maintain the integrity (worth) of all individuals as human beings. Avoid language that objectifies a person by her or his condition (e.g., autistic, neurotic), that uses pictorial metaphors (e.g., wheel- chair bound or confined to a wheelchair), that uses excessive and negative labels (e.g., AIDS victim, brain damaged), or that can be regarded as a slur (e.g., cripple, invalid). Use people-first language, and do not focus on the individual's disabling or chronic condition (e.g., person with paraplegia, youth with autism). Also use people-first lan- guage to describe groups of people with disabilities. For instance, say people with intel- lectual disabilities in contrast to the retarded (University of Kansas, Research and Training Center on Independent Living, 2008).

Avoid euphemisms that are condescending when describing individuals with disabil- ities (e.g., special, physically challenged, handi-capable). Some people with disabilities consider these terms patronizing and offensive. When writing about populations with disabilities or participants, emphasize both capabilities and concerns to avoid reducing them to a "bundle of deficiencies" (Rappaport, 1977). Do not refer to individuals with disabilities as patients or cases unless the context is within a hospital or clinical setting.

3.16 Age Age should be reported as part of the description of participants in the Method section. Be specific in providing age ranges; avoid open-ended definitions such as "under 18 years" or "over 65 years." Girl and boy are correct terms for referring to individuals under the age of 12 years. Young man and young woman and female adolescent and male adolescent may be used for individuals aged 13 to 17 years. For persons 18 years and older, use women and men. The terms elderly and senior are not acceptable as nouns; some may consider their use as adjectives pejorative. Generational descriptors such as boomer or baby boomer should not be used unless they are related to a study on this topic. The term older adults is preferred. Age groups may also be described with adjec- tives. Gerontologists may prefer to use combination terms for older age groups (young- old, old-old, very old, oldest old, and centenarians); provide the specific ages of these groups and use them only as adjectives. Use dementia instead of senility; specify the type of dementia when known (e.g., dementia of the Alzheimer's type). For more references relating to age, see Guidelines for the Evaluation of Dementia and Age-Related Cognitive Decline (APA Presidential Task Force on the Assessment of Age-Consistent Memory Decline and Dementia, 1998) and "Guidelines for Psychological Practice With Older Adults" (APA, 2004; see also www.apastyle.org).

317 Historical and Interpretive Inaccuracies Authors are encouraged to avoid perpetuating demeaning attitudes and biased assump- tions about people in their writing. At the same time, authors need to avoid historical

WRITING CLEARLY AND CONCISELY

and interpretive inaccuracies. Historians and scholars writing literature reviews must

be careful not to misrepresent ideas of the past in an effort to avoid language bias.

Changes in nouns and pronouns may result in serious misrepresentation of the origi-

nal author's ideas and give a false interpretation of that author's beliefs and intentions:

In such writing, it is best to retain the original language and to comment on it in the

discussion. Quotations should not be changed to accommodate current sensibilities

(see sections 4.08 and 6.06). Contemporary authors may indicate a historical author's original term by

ing it with an asterisk the first time it appears and by providing historical context

directly following the quotation. Below is an example of historically appropriate use

of a term that is considered biased by today's standards.

In forming the elite scientific society called the ExperimentaliSts. 1]tchener

"wanted above all to have free, informal interchange between older and

younger men* in the area of experimental psychology, with the goal of socializ-

ing the next generation into the profession" (Furumoto, 1988, p. 105).

*In this example, the term men seems to convey Titchener's intention to exclude

women from the society. Substituting a more gender-neutral or inclusive term may be

historically inaccurate.

Grammar and Usage Incorrect grammar and careless construction of sentences distract the

reader, introduce

ambiguity, and generally obstruct communication. The examples in this section repre-

sent problems of grammar and usage that occur frequently in manuscripts received by

journal editors.

3.18 Verbs Verbs are vigorous, direct communicators. Use the active rather

than the passive voice,

and select tense or mood carefully.

Prefer the active voice.

Preferred:

We conducted the survey in a controlled setting.

Non preferred:

The survey was conducted in a controlled setting.

The passive voice is acceptable in expository writing and when you want to focus

on the object or recipient of the action rather than on the actor. For example, "The

speakers were attached to either side of the chair" emphasizes the placement of speak-

ers, not who placed them—the more appropriate focus in the Method section. "The

President was shot" emphasizes the importance of the person shot

GRAMMAR AND USAGE

Select tense carefully. Use the past tense to express an action or a condition that occurred at a specific, definite time in the past, as when discussing another researcher's work and when reporting your results.

Correct:

Sanchez (2000) presented similar results.

Incorrect:

Sanchez (2000) presents similar results.

Use the present perfect tense to express a past action or condition that did not occur at a specific, definite time or to describe an action beginning in the past and con- tinuing to the present.

Correct:

Since that time, several investigators have used this method. Incorrect:

Since that time, several investigators used this method.

Select the appropriate mood. Use the subjunctive only to describe conditions that are contrary to fact or improbable; do not use the subjunctive to describe simple condi- tions or contingencies.

If the experiment were not designed this way, the results could not be inter- preted properly.

Incorrect:

If the experiment was not designed this way, the results could not be inter- preted properly.

Use would with care. Would can correctly be used to mean habitually, as "The child would walk about the classroom," or to express a conditional action, as "We would sign the letter if we could." Do not use would to hedge; for example, change it would appear that to it appears that.

3.20 Pronouns Pronouns replace nouns. Each pronoun should refer clearly to its antecedent and should agree with the antecedent in number and gender.

A pronoun must agree in number (i.e., singular or plural) with the noun it replaces.

Correct:

Incorrect:

Neither the highest scorer nor the lowest scorer in the group had any doubt about their competence.

pronoun must agree in gender (i.e., masculine, feminine, or neuter) with the noun it replaces. This rule extends to relative pronouns (pronouns that link subordi- nate clauses to nouns). Use who for human beings; use that or which for nonhuman animals and for things.

Correct:

The students who completed the task successfully were rewarded.

Correct:

The instructions that were included n the experiment were complex.

GRAMMAR AND USAGE

Use neuter pronouns to refer to animals (e.g., "the dog . . . it") unless the animals have been named:

The chimps were tested daily. . . . Sheba was tested unrestrained in an open testing area, which was her usual context for training and testing.

Pronouns can be subjects or objects of verbs or prepositions. Use who as the subject of a verb and whom as the object of a verb or a preposition. You can determine whether a relative pronoun is the subject or object of a verb by turning the subordinate clause around and substituting a personal pronoun. If you can substitute he or she, who is correct; if you can substitute him or her, whom is correct.

3.21 Misplaced and Dangling Modifiers and Use of Adverbs

An adjective or an adverb, whether a single word or a phrase, must clearly refer to the word it modifies.

Misplaced modifiers. Because of their placement in a sentence, misplaced modifiers ambiguously or illogically modify a word. You can eliminate misplaced modifiers by placing an adjective or an adverb as close as possible to the word it modifies.

Correct:

Using this procedure, the investigator tested the participants.

me Correct:

is The investigator tested the participants who were using the procedure.

Incorrect:

The investigator tested the participants using this procedure. [The sentence is unclear about whether the investigator or the participants used this procedure.]

Correct:

On the basis of this assumption, we developed a model.

Correct:

Based on this assumption, the model.

Incorrect:

Based on this assumption, we developed a model. . . . [This construction says, "we are based on an assumption."]

Many writers have trouble with the word only. Place only next to the word or phrase it modifies.

Correct:

These data provide only a partial answer.

Incorrect:

These data only provide a partial answer.

Dangling modifiers. Dangling modifiers have no referent in the sentence. Many of these result from the use of the passive voice. By writing in the active voice, you can avoid many dangling modifiers.

Correct:

Using this procedure, I tested the participants. [I, not the participants, used the procedure.]

Incorrect:

The participants were tested using this procedure.

GRAMMAR AND USAGE

Correct:

Mulholland and Williams (2000) found that this group performed better, a result that is congruent with those of other studies [The result, not Mulholland and Williams, is congruent.J

Incorrect:

Congruent with other studies, Mulholland and Williams (2000) found that this

H group performed better.

Adverbs. Adverbs can be used as introductory or transitional words. Adverbs modify verbs, adjectives, and other adverbs and express manner or quality. Some adverbs, however—such as fortunately, similarly, certainly, consequently, conversely, and regret- tably—can also be used as introductory or transitional words as long as the sense is confined to, for example, "it is fortunate that" or "in a similar manner." Use adverbs judiciously as introductory or transitional words. Ask yourself whether the introduc. tion or transition is needed and whether the adverb is being used correctly.

Some of the more common introductory adverbial phrases are importantly, more importantly, interestingly, and firstly. Although importantly is used widely, whether its adverbial usage is proper is debatable. Both importantly and interestingly can often be recast to enhance the message of a sentence or simply be omitted without a loss of meaning.

Correct: A More important, the total amount of available long1erm memory activation,

tland not the rate of spreading activation, drives the rate and probability of retrieval.

Correct:

Expressive behavior and autonomic nervous system activity also have figured importantly.

Incorrect:

More importantly, the total amount of available long-term memory activation, and not the rate of spreading activation, drives the rate and probability of retrieval.

Correct:

We were surprised to learn that the total. . We find it interesting that the total. , An interesting finding was that. .

Incorrect:

Correct:

First, we hypothesized that the quality of the therapeutic alliance would be ratedi higher. .

WRITING CLEARLY AND CONCISELY L 831

Incorrect:

Firstly, we hypothesized that the quality of the therapeutic alliance would be rated higher.

Another adverb often misused as an introductory or transitional word is hopefully. Hopefully means "in a hopeful manner" or "full of hope"; hopefully should not be used to mean "I hope" or "it is hoped."

Correct:

I hope this is not the case.

Incorrect:

Hopefully, this is not the case.

322 Relative Pronouns and Subordinate Conjunctions Relative pronouns (who, whom, that, which) and subordinate conjunctions (e.g., since, while, although) introduce an element that is subordinate to the main clause of the sen- tence and reflect the relationship of the subordinate element to the main clause. Therefore, select these pronouns and conjunctions with care; interchanging them may reduce the precision of your meaning.

Relative pronouns. That versus which. That clauses (called restrictive) are essential to the meaning of

the sentence:

The materials that worked well in the first experiment were used in the second experiment.

Which clauses can merely add further information (nonrestrictive) or can be essen- tial to the meaning (restrictive) of the sentence. APA prefers to reserve which for non- restrictive clauses and use that in restrictive clauses.

Restrictive:

The cards that worked well in the first experiment were not useful in the sec- ond experiment. [Only those cards that worked well in the first experiment were not useful in the second; prefer that.]

Nonrestrictive:

The cards, which worked well in the first experiment, were not useful in the sec- ond experiment. [The second experiment was not appropriate for the cards.]

Consistent use of that for restrictive clauses and which for nonrestrictive clauses, which are set off with commas, will help make your writing clear and precise.

Subordinate conjunctions. While and since. Some style authorities accept the use of while and since when they

do not refer strictly to time; however, words like these, with more than one meaning, can cause confusion. Because precision and clarity are the standards in scientific writ-

GRAMMAR AND USAGE

ing, restricting your use of while and since to their temporal meanings is helpful. The following examples illustrate the temporal meanings of these terms:

Bragg (1965) found that participants performed well while listening to music

Several versions of the test have been developed since the test was first introduced.

While versus although, and, or hut. Use while to link events occurring simultaneous- ly; otherwise, use although, and, or but in place of while.

Precise:

Although these findings are unusual, they are not unique.

Imprecise:

While these findings are unusual, they are not unique.

• Precise:

The argument is purely philosophical, but the conclusion can also yield an empir- ical hypothesis, amenable to empirical investigation.

••

Imprecise:

While the argument is purely philosophical, the conclusion can also yield an empirical hypothesis, amenable to empirical investigation.

Since versus because. Since is more precise when it is used to refer only to time (to mean "after that"); otherwise, replace it with because.

Precise:

Data for two participants were incomplete because these participants did not report for follow-up testing.

Imprecise:

Data for two participants were incomplete since these participants did not report for follow-up testing.

3.23 Parallel Construction To enhance the reader's understanding, present parallel ideas in parallel or coordinate form. Make certain that all elements of the parallelism are present before and after the coordinating conjunction (i.e., and, but, or, nor).

Correct:

The results show that such changes could be made without affecting error rate and that latencies continued to decrease over time.

• Incorrect:

The results show that such changes could be made without affecting error rate and latencies continued to decrease over time.

WRITING CLEARLY AND CONCISELY

With coordinating conjunctions used in pairs (between. . and, both . . . and, neither nor, either. . or, not only . . but also), place the first conjunction immediately

before the first part of the parallelism.

Between and and.

Correct:

We recorded the difference between the performance of subjects who complet- ed the first task and the performance of those who completed the second task. [The difference is between the subjects' performances, not between the per- formance and the task.]

Incorrect;

We recorded the difference between the performance of subjects who com- pleted the first task and the second task.

Correct:

Both and and.

Correct;

The names were difficult both to pronounce and to spell.

Incorrect:

The names were both difficult to pronounce and spell.

Never use both with as well as: The resulting construction is redundant.

Correct:

The names were difficult to pronounce as well as to spell.

Incorrect:

The names were difficult both to pronounce as well as to spell.

Neither and nor; either and or.

Correct;

Neither the responses to the auditory stimuli nor the responses to the tactile stimuli were repeated.

Incorrect

Neither the responses to the auditory stimuli nor to the tactile stimuli were repeated

AND USAGE

Correct:

The respondents either gave theworst answer or gave the best answer.

or

The respondents gave either the worst answer or the best answer.

Incorrect:

Not only and but also.

Correct:

It is surprising not only that pencil-and-paper scores predicted this resuit but also that all other predictors were less accurate.

Incorrect:

It is not only surprising that pencil-and-paper scores predicted this result but aiso that all other predictors were less accurate.

Elements in a series should also be parallel in form.

Correct:

The participants were told to make themselves comfortable, to read the instruc- tions, and to ask about anything they did not understand.

Incorrect:

The participants were told to make themselves comfortable, to read the instruc- tions, and that they should ask about anything they did not understand.

Take care to use parallel structure in lists and in table stubs (see sections 3.04 and 5.13)

The Mechanics of Style

W hen editors refer to style, they mean the rules or guidelines a publisher observes to ensure clear, consistent presentation in scholarly articles. Authors writing for a publication must follow the style rules established by the publisher to avoid

inconsistencies among journal articles or book chapters. For example, without rules of style, three different manuscripts might use sub-test, subtest, and Subtest in one issue of a journal or in one book. Although the meaning of the word is the same and the choice of one style over the other may seem arbitrary (in this case, subtest is APA Style), such vari- ations in style may distract or confuse the reader.

This chapter describes the style for APA journals regarding the most basic tools for conveying meaning—punctuation, spelling, capitalization, italics, abbreviations, num- bers, metrication, and statistics. It omits general rules explained in widely available style manuals and examples of usage with little relevance to APA journals. Style man- uals agree more often than they disagree; where they disagree, the Publication Manual takes precedence for APA publications.

Punctuation Punctuation establishes the cadence of a sentence, telling the reader where to pause (comma, semicolon, and colon), stop (period and question mark), or take a detour (dash, parentheses, and brackets). Punctuation of a sentence usually denotes a pause in thought; different kinds of punctuation indicate different kinds and lengths of pauses.

4.01 Spacing After Punctuation Marks Insert one space after

• commas, colons, and semicolons; * periods that separate parts of a reference citation; and

PUNCTUATION

a periods of the initials in personal names (e.g., J. R. Zhang)

Exception: Do not insert a space after internal periods in abbreviations (e.g., am., i.e., U.S.), including identity-concealing labels for study participants (ElM.), or around colons in ratios. Space twice after punctuation marks at the end of a sentence.

4.02 Period Use a period to end a complete sentence. Periods are used with abbreviations as follows:

Use periods with

• initials of names (J. FR. Smith).

• abbreviation for United States when it is used as an adjective (U.S. Navy). • identity-concealing labels for study participants (ElM.). (See section 4.01 on spacing.) • Latin abbreviations (am., cf., i.e., vs.). • reference abbreviations (Vol. 1, 2nd ed., p. 6, F Supp.).

Do not use periods with

• abbreviations of state names (NY; OH; Washington, DC) in reference list entries or in vendor locations (e.g., for drugs and apparatus described in the Method section).

• capital letter abbreviations and acronyms (APA, NDA, NIMH, 10). • abbreviations for routes of administration (icy, im, p. iv, sc). • web addresses in text or in the reference list (http://www.apa.org), In text, include

these in parentheses when possible or revise the sentence to avoid ending a sentence with a URL and no punctuation.

• metric and nonmetric measurement abbreviations (Cd, cm, ft, hr, kg, Ib, mm, ml, s).

Exception: The abbreviation for inch (in.) takes a period because without the period it could be misread.

4.03 Comma Use a comma

• between elements (including before and and or) in a series of three or more items.

4.13 Hyphenation Compound words take many forms; that is, two words may be written as (a) two sep- arate words; (b) a hyphenated word; or (c) one unbroken, "solid" word. Choosing the proper form is sometimes frustrating. For example, is follow up, follow-up, or followup the form to be used? The dictionary is an excellent guide for such decisions, especially for nonscientific words (the term is follow-up when functioning as a noun or adjective but follow up when functioning as a verb). When a compound can be found in the dictionary, its usage is established and it is known as a permanent corn- pound (e.g., high school, caregiver, and self-esteem). Dictionaries do not always agree on the way a compound should be written (open, solid, or hyphenated); APA follows Webster's Collegiate in most cases. Compound terms are often introduced into the lan- guage as separate or hyphenated words, and as they become more commonplace, they tend to fuse into a solid word. For example, the hyphen was dropped from life-style in the 11th edition of Webster's Collegiate, and data base is now database.

There is another kind of compound—the temporary compound—which is made up of two or more words that occur together, perhaps only in a particular paper, to express a thought. Because language is constantly expanding, especially in science, temporary compounds develop that are not yet listed in the dictionary. If a temporary compound modifies another word, it may or may not be hyphenated, depending on (a) its position in the sentence and (b) whether the pairing of a compound with another word can cause the reader to misinterpret meaning. The main rule to remember is that if a temporary compound precedes what it modifies, it may need to be hyphenated, and if it follows what it modifies, it usually does not. If a compound is not in the diction- ary, follow the general principles of hyphenation given here and in Table 4.1. If you are still in doubt, use hyphens for clarity rather than omitting them. (See also Tables 4.2 and 4.3 for treatment of prefixes and suffixes.)

Hyphens, dashes, and minus signs are each typed differently.

• hyphen: Use no space before or after (e.g., trial-by-trial analysis). • em dash: An em dash is longer than a hyphen or an en dash and is used to set off an

element added to amplify or to digress from the main clause (e.g., Studies—published and unpublished—are included). Use no space before or after an em dash. If an em dash is not available on your keyboard, use two hyphens with no space before or after.

• en dash: An en dash is longer and thinner than a hyphen yet shorter than an em dash and is used between words of equal weight in a compound adjective (e.g., Chicago— London flight). Type as an en dash or, if the en dash is not available on your keyboard, as a single hyphen. In either case, use no space before or after.

• minus sign: A typeset minus sign is the same length as an en dash, but it is slightly thicker and slightly higher. If a minus sign is not available in your word- processing program, use a hyphen with a space on both sides (e.g., a - b). For a negative value, use a hyphen rather than a minus sign, with a space before but no space after (e.g., -5.25).

modify the noun). For example, are different word lists (a) word lists that are different from other word lists (if so, different modifies word lists; thus, write different word lists) or (b) lists that present different words (if so, the first word modifies the second, and together they modify lists, thus, different-word lists). Likewise, "the adolescents resided in two parent homes" means that two homes served as residences, whereas if the adoles- cents resided in "two-parent homes," they each would live in a household headed by two parents. A properly placed hyphen helps the reader understand the intended meaning.

General Principle 3 Most compound adjective rules are applicable only when the compound adjective pre- cedes the term it modifies. If a compound adjective follows the term, do not use a hyphen, because relationships are sufficiently clear without one. The following exam- ples are all correctly hyphenated:

Abbreviations 422 Use of Abbreviations To maximize clarity, use abbreviations sparingly. Although abbreviations are sometimes

useful for long, technical terms in scientific writing, communication is usually garbled

rather than clarified if, for example, an abbreviation is unfamiliar to the reader.

Overuse. Consider whether the space saved by abbreviations in the following sentence

justifies the time necessary to master the meaning:

The advantage of the LH was clear from the RT data, which reflected high FP

and FN rates for the RH.

Without abbreviations the passage reads as follows:

The advantage of the left hand was clear from the reaction time data, which

reflected high false-positive and false-negative rates for the right hand.

linderuse. Abbreviations introduced on first mention of a term and used fewer than three tinies thereafter, particularly in a long paper, may be difficult for a reader to remember, and you probably serve the reader best if you write them out each time. In the following exam- ple, however, a standard abbreviation for a long, familiar term eases the reader's task:

Patients at seven hospitals completed the MMPI—2.

Deciding whether to abbreviate. In all circumstances other than in the reference list (see section 6.22) and in the abstract, you must decide whether (a) to spell out a given expression every time it is used in an article or (b) to spell it out initially and abbrevi- ate it thereafter. For example, the abbreviations L for large and S for small in a paper discussing different sequences of reward (LLSS or LSLS) would be an effective and readily understood shortcut. In another paper, however, writing about the L reward and the S reward would be both unnecessary and confusing. In most instances, abbre- viating experimental group names is ineffective because the abbreviations are not ade- quately informative or easily recognizable and may even be more cumbersome than the full name. In general, use an abbreviation only (a) if it is conventional and if the reader is more familiar with the abbreviation than with the complete form or (b) if consider- able space can be saved and cumbersome repetition avoided. In short, use only those abbreviations that will help you communicate with your readers. Remember, they have not had the same experience with your abbreviations as you have.

423 Explanation of Abbreviations Because the abbreviations that psychologists use in their daily writing may not be famil- iar to students or to readers in other disciplines or other countries, a term to be abbrevi- ated must, on its first appearance, be written out completely and followed immediately by its abbreviation in parentheses. Thereafteç use the abbreviation in text without further explanation (do not switch between the abbreviated and written-out forms of a term).

The results of studies of simple reaction time (RT) to a visual target have shown a strong negative relation between RT and luminance.

Explain abbreviations that appear in a figure in the caption or legend. Explain those that appear in a table either in the table title (if it includes words that are abbre- viated in the table body; see section 5.12) or in the table note (see section 5.16). Explain an abbreviation that is used in several figures or tables in each figure or table in which the abbreviation is used. Avoid introducing abbreviations into figure captions or table notes if they do not appear in the figure or table. Standard abbreviations for units of measurement do not need to be written out on first use (see section 4.27).

4.24 Abbreviations Accepted as Words APA Style permits the use of abbreviations that appear as word entries (i.e., that are not labeled abbr) in Merriam-Webster's Collegiate Dictionary (2005). Such abbrevia- tions do not need explanation in text.

Chemical compounds. Chemical compounds may be expressed by common name or by

chemical name. If you prefer to use the common name, provide the chemical name in

parentheses on first mention in the Method section. Avoid expressing compounds with

chemical formulas, as these are usually less informative to the reader and have a high

likelihood of being typed or typeset incorrectly (e.g., aspirin or salicylic acid, not

C9H804). If names of compounds include Greek letters, retain the letters as symbols and

do not write them out (e.g., 3 carotene, not beta carotene).

Long names of organic compounds are often abbreviated; if the abbreviation is

listed as a word entry in Merriam-Webster's Collegiate Dictionary (2005; e.g., NADP

for nicotinamide adenine dinucleotide phosphate), you may use it freely, without writ-

ing it out on first use.

Concentrations. If you express a solution as a percentage concentration instead of as a

molar concentration, be sure to specify the percentage as a weight-per-volume ratio

(wt/vol), a volume ratio (vol/vol), or a weight ratio (wt/wt) of solute to solvent. The

higher the concentration is, the more ambiguous the expression as a percentage.

Specifying the ratio is especially necessary for concentrations of alcohol, glucose, and

sucrose. Specifying the salt form is also essential for precise reporting: a-amphetamine

HCI or d-amphetamine SO4 (note that expression of chemical name in combination

with a formula is acceptable in this case).

12% (vol/vol) ethyl alcohol solution

Routes of administration. You may abbreviate a route of administration when it is paired

with a number-and-unit combination. Preferred style for APA is no periods: icy = intra-

Begin a sentence with a capitalized abbreviation or acronym (e.g., U.S. or APA) or with a symbol connected to a word (e.g., 3-Endorphins) only when neces- sary to avoid indirect and awkward writing. In the case of chemical compounds, cap- italize the first letter of the word to which the symbol is connected; keep the locant, descriptor, or positional prefix (i.e., Greek, small capital, and italic letters and numer- als) intact.

The number of decimal places to use in reporting the results of experiments and data analytic manipulations of the data should be governed by the following general principle: Round as much as possible while keeping prospective use and statistical pre- cision in mind. As a general rule, fewer decimal digits are easier to comprehend than more digits; therefore, in general, it is better to round to two decimal places or to rescale the measurement (in which case effect sizes should be presented in the same metric). For instance, a difference in distances that must be carried to four decimals to be seen when scaled in meters can be more effectively illustrated in millimeters, which

METRICATION

would require only a few decimal digits to illustrate the same difference. As a rule,

when properly scaled, most data can be effectively presented with two decimal digits

of accuracy. Report correlations, proportions, and inferential statistics such as t, F, and

to two decimals. When reporting p values, report exact p values (e.g., p = .031) to two or three dec-

imal places. However, report p values less than .001 as p .c .001. The tradition of

reporting p values in the form p c .10, p < .05, p < .01, and so forth, was appropriate

in a time when only limited tables of critical values were available. However, in tables

the "p c" notation may be necessary for clarity (see section 5.16). 4

Metrication 4.39 Policy on Metrication APA uses the metric system in its journals. All references to

physical measurements,

where feasible, should be expressed in metric units. The metric system outlined in

this section is based, with some exceptions, on the International System of Units (SI),

which is an extension and refinement of the traditional metric system and is support-

ed by the national standardizing bodies in many countries, including the United

States. In preparing manuscripts, use metric units if possible. If you use instruments that

record measurements in nonmetric units, you may report the nonmetric units but also

THE MECHANICS OF STYLE

report the established SI equivalents in parentheses immediately after the nonmetric units.

The rods were spaced 19 mm apart. [Measurement was made in metric units.] The rod was 3 ft (0.91 m) long. [Measurement was made in nonmetric units and converted to the rounded SI equivalent.]

4.40 Style for Metric Units Abbreviation. Use the metric symbol (see International System [SI] Base and Supplementary Units and other resources on metrication at wwwspastyle.org) to express a metric unit when it appears with a numeric value (e.g., 4 m). When a metric unit does not appear with a numeric value, spell out the unit in text (e.g., measured in meters) and use the metric symbol in column and headings of tables to conserve space (e.g., lag in ms). Capitalization. Use lowercase letters when writing out full names of units (e.g., meter, nanometer), unless the name appears in capitalized material or at the beginning of a sentence.

For the most part, use lowercase letters for symbols (e.g., cd), even in capitalized material. Symbols derived from the name of a person usually include uppercase letters (e.g., Gy), as do symbols for some prefixes that represent powers of 10: exa (E), peta (P), tera (T), giga (G), and mega (M). (See Table 4.4 for more examples.)

Use the symbol L for liter when it stands alone (e.g., 5 L, 0.3 mg/L) because a low- ercase 1 may be misread as the numeral one (use lowercase I for fractions of a liter: 5 ml, 9 ng/dl).

Plurals. Make full names of units plural when appropriate.

meters

Do not make symbols or abbreviations of units plural.

3cm, not3 cms

Periods. Do not use a period after a symbol, except at the end of a sentence. Spacing. Use a space between a symbol and the number to which it refers, except for measures of angles (e.g., degrees, minutes, and seconds).

4.5 m, 12 °C, but 45° angle

Compound units. Use a centered dot between the symbols of a compound term formed by the multiplication of units.

Use a space between full names of units of a compound unit formed by the multiplica- tion of units; do not use a centered dot.

I STATISTICAL AND MATHEMATICAL COPY

Statistical and Mathematical Copy APA Style for presenting statistical and

mathematical copy reflects (a) standards of con-

tent and form agreed on in the field and (b) the requirements of clear communication.

4.41 Selecting Effective Presentation

Statistical and mathematical copy can be presented in text, in tables, and in figures.

Detailed discussions of principles for the generation of tables, figures, and graphs can

be found in Chapter 5. In deciding which approach to take, a general rule that might

prove useful is

• if you need to present three or fewer numbers, first try using a sentence;

• if you need to present four to 20 numbers, first consider using a well-prepared table;

and • if you have more than 20 numbers, a graph is often more useful

than a table.

Select the mode of presentation that optimizes understanding of the data by the

reader. Detailed displays that allow fine-grained understanding of a data set may be

more appropriate to include in online supplemental archives (see section 2.13) than in

the print version of an article. Tables, figures, charts, and other graphics should be pre-

pared with the understanding that if the manuscript is accepted, they are to be pub-

lished at the editor's discretion. In any case, be prepared to submit tables and figures

of complex statistical and mathematical material if an editor requests them.

4.42 References for Statistics Do not give a reference for statistics in common use; this

convention applies to most

statistics in journal articles. Do give a reference when (a) less common statistics

are used, especially those that have appeared so recently that they can be found only

in journals; (b) a statistic is used in an unconventional or a controversial way; or (c)

the statistic itself is the focus of the article.

4.43 Formulas Do not give a formula for a statistic in common use; do give a

formula when the sta-

tistic or mathematical expression is new, rare, or essential to the manuscript.

Presentation of equations is described in sections 4.47—4.48.

4 44 Statistics in Text When reporting inferential statistics (e.g., t tests, F tests, tests,

and associated effect

sizes and confidence intervals), include sufficient information to allow the reader to fully 4

understand the analyses conducted. The data supplied, preferably in the text but possibly

in an online supplemental archive depending on the magnitude of such data arrays, should

allow the reader to confirm the basic reported analyses (e.g., cell means, standard devia PI

tions, sample sizes, and correlations) and should enable the interested reader to construct

some effect-size estimates and confidence intervals beyond those supplied in the paper per

se. In the case of multilevel data, present summary statistics for each level of aggregation.

What constitutes sufficient information depends on the analytic approach reported.

THE MECHANICS OF STYLE

For immediate recognition, the omnibus test of the main effect of sentence for- mat was statistically significant, F(2, 177) = 6.30, p = .002, est w2 = .07. The one- degree-of-freedom contrast of primary interest (the mean difference between Conditions 1 and 2) was also statistically significant at the specified .05 level, t(1 77) = 3.51, pc .001, d= 0.65, 95% Cl [0.35, 0.95].

High-school GPA statistically predicted college mathematics performance, =

.12, F(1, 148)=20.18, pc .001, 95% Cl [.02, .22]. The four-subtest battery added to this prediction, 82 = .21, tsR2 = .09, F(4, 144) = 3.56, p = .004, 95% Cl [.10, .32]. Most important, when the two preceding variables were statistically accounted for, the college mathematics placement examination also explained unique variance in students' college mathematics performance, 82 = .25, AR2 = .04, F(1, 143) = 7.63, p= .006, 95% Cl 1.13, .37].

If you present descriptive statistics in a table or figure, you do not need to repeat them in text, although you should (a) mention the table in which the statistics can be found and (b) emphasize particular data in the narrative when they help in interpreta- tion of the findings.

When enumerating a series of similar statistics, be certain that the relation between the statistics and their referents is cleat Words such as respectively and in order can clarify this relationship.

Means (with standard deviations in parentheses) for Trials 1 through 4 were 2.43 (0.50). 2.59 (1.21), 2.68 (0.39), and 2.86 (0.12), respectively.

When reporting confidence intervals, use the format 95% Cl ILL, UL], where LL is the lower limit of the confidence interval and UL is the upper limit.

When a sequence of confidence intervals is repeated in a series or within the same paragraph and the level of confidence (e.g., 95%) has remained unchanged, and the meaning is clear, you do not need to repeat the 95% CI. Every report of a confidence interval must clearly state the level of confidence. A sentence might then read, in part,

95% CIs [5.62, 8.31), [—2.43, 4.31], and [—4.29, —3.11], respectively

When a confidence interval follows reporting of a point estimate, the units of measurement should not be repeated:

M=30.5 cm, 99% Cl [18.0, 43.0]

resented by Greek letters. Most estimators are represented by italicized Latin letters.

For example, the population correlation would be represented as p, and the estimator

would be represented as r. [Est(p) and are also acceptablel. Some test statistics are

represented by italicized Latin letters (e.g., tand F), and a few are represented by Greek

letters (e.g., F).

Symbols for number of subjects. Use an uppercase, italicized N to designate the num-

ber of members in the total sample (e.g., N = 135) and a lowercase, italicized n to des-

ignate the number of members in a limited portion of the total sample (e.g., n = 30).

Symbol for percentage. Use the symbol for percent only when it is preceded by a

numeral. Use the word percentage when a number is not given.

Exception: In table headings and figure legends, use the symbol % to conserve space.

Standard, boldface, and italic type. Statistical symbols and mathematical copy in man-

uscripts are prepared with three different typefaces: standard, boldface, and italic. The

same typeface is used in text, tables, and figures. Greek letters, subscripts, and superscripts that function as

identifiers (i.e., are not

variables) and abbreviations that are not variables (e.g., log, GLM, WLS) are set in stan-

dard typeface.

On occasion, an element may serve as both an abbreviation and a symbol (e.g., SD);

in those cases, use the typeface that reflects the function of element (see Table 4.5).

Identifying letters and symbols. As with all aspects of manuscript preparation, take care

to ensure that there are no ambiguities that could lead to errors in the final production

steps, particularly with mathematical and statistical symbols, non-English characters, :2

and complex alignments (e.g., subscripts and superscripts). Avoid misunderstandings 4

and corrections by preparing mathematical copy carefully.

4.46 Spacing, Alignment and Punctuation

Space mathematical copy as you would space words: a+b=c is as difficult to read as

wordswithouts pacing. Instead, type a + b = c.

Align signs and symbols carefully. Use the subscript and superscript features in

your word-processing software. In most cases, type subscripts first and then super-

I Summation Note. Some forms are used as both abbreviations and symbols. Use the abbreviation form when referring to the concept and the symbol form when specifying a numeric value. As a rule, the symbol torm will be either a non-English letter or an itahcized version of the Engiish otter form. Most abbreviations can be turned into symbols (for use when reporting numerical estimates) by simply italicizing the abbreviation. In addition, it is acceptable to use the form estlo) orO to indicate an estimator or estimate of the parameter 9.

scripts (xi). However, place a superscript such as the symbol for prime right next to its letter or symbol Because APA prefers to align subscripts and superscripts one under the other (stacking) for ease of reading instead of setting one to the right of the other (staggering), that is how they are normally typeset. If subscripts and superscripts should not be stacked, so indicate in a cover letter or on the manuscript.

Equations Punctuate all equations, whether they are in the line of text or displayed (i.e., typed on a new line), to conform to their place in the syntax of the sentence (see the period fol- lowing Equation 3 in section 4.48). If an equation exceeds the column width of a type- set page (approximately 55 characters, including spaces, will fit on one line in most APA journals), the typesetter will break it. For long equations, indicate on the final ver- sion of the accepted manuscript where breaks would be acceptable.

4.47 Equations in Text Place short and simple equations, such as a = [(1 + b)/x1112, in the line of text. Equations in the line of text should not project above or below the line; for example, the equa- tion above would be difficult to set in the line of text if it were in this form:

/i +b a = Vx

To present fractions in the line of text, use a slanted line (I) and appropriate paren- theses, brackets, and braces: Use ( ) first, then [C H, and finally {[( )fl. Use parentheses and brackets to avoid ambiguity: Does a/b + c mean (a/b) + c or a/tb + c)?

4.48 Displayed Equations Display simple equations if they must be numbered for later reference. Display all com- plex equations. Number all displayed equations consecutively, with the number in parentheses near the right margin of the page:

MXmEOUATIONS Ti W1 ± ZhxI2ÔWj

When referring to numbered equations, write out the reference; for example, write

Equation 3 (do not abbreviate as Eq. 3), or write the third equation.

4.49 Preparing Statistical and Mathematical Copy

If possible, type all signs and symbols in mathematical copy. Supply as camera-ready

copy any special symbols that cannot be produced by a word-processing program.

Type fences (i.e., parentheses, brackets, and braces), uppercase and lowercase letters,

punctuation, subscripts and superscripts, and all other elements exactly as you want

them to appear in the published article. Follow the conventions for the use of symbols,

equations, and reporting results presented in the earlier sections of this chapter.

Displaying Results

S ince the last edition of the Publication Manual, few areas have been affected by tech- nological developments more dramatically than the methods available for the dis- play of results of experimentation and inquiry—tables, graphs, charts, maps, draw-

ings, and photographs. Almost all displays are now the results of electronic manipulation of basic data—be it with word-processing programs, spreadsheet programs, statistical packages, or highly specialized software for creating digital images. These changes have greatly increased the flexibility that authors have for effectively displaying results.

Tables and figures enable authors to present a large amount of information efficient- ly and to make their data more comprehensible. Tables usually show numerical values or textual information (e.g., lists of stimulus words) arranged in an orderly display of columns and rows. A figure may be a chart, a graph, a photograph, a drawing, or any other illustration or nontextual depiction. At times the boundary between tables and fig- ures may be undear; however, tables are almost always characterized by a row—column structure. Any type of illustration other than a table is referred to as a figure.

In this chapter, we discuss the purposes that data displays can serve and provide guidance on designing and preparing data displays so that they communicate most effectively. We provide specific guidance on formatting and constructing tables and fig- ures, along with a number of illustrative examples.

General Guidance on Tables and Figures 5.01 Purposes of Data Displays Data displays can serve several purposes:

• exploration: the data contain a message, and you would like to learn what it is (exploratory data analysis and data mining techniques are examples of displays that

1 V are principally exploratory);

GENERAL GUIDANCE ON TABLES AND FIGURES

• communication: you have discovered the meaning contained in the data and want to tell others about it (this is the traditional purpose of most data displays in scientific documents);

• calculation: the display allows you to estimate some statistic or function of the data (nomographs are the archetype of this);

• storage: you can store data in a display for retrieval later, including the results of a study for later use in a meta-analysis (historically, this role has been fulfilled by tables, but figures sometimes serve this purpose more efficiently); and

• decoration: data displays attract attention, and you may choose to use them to make your manuscript more visually appealing (as in newspapers and other media reports).

In scientific publication, the communication function of graphical displays dominates; however, other features (e.g., storage) may be useful in a graphical representation.

5.02 Design and Preparation of a Data Display The first step in preparing a display for submission is to determine the purposes of the display and the relative importance of those purposes. For example, the detail required for a storage display may conflict with the clarity required for a communicative one. Once you have decided on a display's hierarchy of purposes, choose the template best designed for its primary purpose—the canonical form of a display. Such a display (e.g., a scatterplot) has shown itself to be flexible (it works for many kinds of data), robust (it works reasonably well even when it is not exactly suitable), and adaptive (it shows a capacity for adaptation to make it suitable). Further, the use of canonical forms sim- plifies the task of readers trying to make sense of a display because they can rely on past experience with the form.

The preparation of graphic materials requires careful attention to organization and content. Graphical elements need to be edited with the same care as the textual ele- ments of a manuscript. Changes in text often demand changes in graphical elements, and failure to edit graphical materials and to sharpen the focus of the display is a major shortcoming in much scientific writing.

Design your graphical display with the reader in mind; that is, remember the com- municative function of the display.

• Place items that are to be compared next to each other. • Place labels so that they clearly abut the elements they are labeling. • Use fonts that are large enough to be read without the use of magnification. • Include all of the information needed to understand it within the graphical image—

avoid novel abbreviations, use table notes, and label graphical elements. • Keep graphical displays free of extraneous materials, no matter how decorative

those materials may make the graphic look.

Communication is the primary purpose of the graphic. This does not mean, however, that well-designed, aesthetically pleasing graphics are not important. An attractive -] graphical display makes a scientific article a more effective communication device.

5.03 Graphical Versus Textual Presentation Be selective in choosing how many graphical elements to include in your paper. First, a reader may have difficulty sorting through a large number of tables and figures and

DISPLAYING

may lose track of your message. Second, a disproportionately large number of tables and figures compared with a small amount of text can cause problems with the layout of typeset pages; text that is constantly broken up with tables will be hard for the read- er to follow. Third, graphical presentations are not always optimal for effective com- munication. For example, the results of many standard statistical significance tests can often be effectively presented in text:

The one-way ANOVA, F(1, 136) = 4.86, MSE = 3.97, p = .029, = .03, demon- strated statistically significant differences between the two groups, as theory would dictate.

Information that used to be routinely presented in tables (e.g., analysis of variance [ANOVA} tables) is now routinely presented in text.

5.04 Formatting Tables and Figures Most manuscripts are now submitted electronically; therefore, all the elements of the manuscript must be in electronic format. These elements may be produced in many different file formats (e.g., .doc, .jpg, .pps, .pdf), and any publisher may limit the for- mats it accepts. Most tables are constructed with the tables feature of the word-pro- cessing program used to generate the manuscript text. However, tables are sometimes cut and from computer outputs (rarely recommended) or may be PDF images created from scans of tables prepared in other ways. When tables are prepared with standard word-processing programs, the text can be converted directly into typo- graphic files, thereby lowering the probability of typesetting errors. Figures are gen- erally submitted in a variety of formats, as is necessitated by the multiple ways in which they are produced. Often, figures such as graphs and charts are initially pro- duced with presentation software such as Microsoft PowerPoint. Photographic ele- ments are generally limited to specific image formats that allow for clear resolution of the image in its printed application. As a rule, figures are reproduced in the print version of articles as they are received from the author (following any editorial changes approved by the editor).

For publishers that offer online supplemental archives, carefully delineate the materials that will appear with the article from those that will be placed in the online supplemental archive (see section 2.13). Because of the relatively high cost of color reproduction, include it only when the color representation adds significantly to the understanding of the material. If color representation is not crucial for immediate understanding, you may consider placing it online as supplemental material.

5.05 Table and Figure Numbers Number all tables and figures with Arabic numerals in the order in which they are first mentioned in text, regardless of whether a more detailed discussion of the table or fig- ure occurs later in the paper. Do not use suffix letters to number tables and figures; that is, label them as Table 5, Table 6, and Table 7 or Figure 5, Figure 6, and Figure 7 instead of 5, Sa, and Sb. If the manuscript includes an appendix with tables or figures, identify those elements of the appendix with capital letters and Arabic numerals (e.g., Table Al is the first table of Appendix A or of a sole appendix that is not labeled with a letter; Figure C2 is the second figure of Appendix C).

TABLES

5.06 Permission to Reproduce Data Displays

If you reproduced or adapted a table, figure, questionnaire, or test item from a copy- righted source, you must obtain written permission for print and electronic reuse

from the copyright holder and give credit in the table or figure caption to the origi-

nal author and copyright holder. A number of commercial instruments—for example,

intelligence tests and projective measures—are highly protected. Permission is required, and may be denied, to republish even one item from such instruments. Any

reproduced table (or figure) or part thereof must be accompanied by a note at the bot-

tom of the reprinted table (or in the figure caption) giving credit to the original author

and to the copyright holder (see section 2.12 for the correct wording of copyright per-

mission footnotes). For detailed information on copyright and permissions, see sec-

tion 6.10.

Tables When planning tables for inclusion in a manuscript, determine (a) the data readers will

need to understand the discussion and (b) the data necessary to provide the "sufficient

set of statistics" (see section 4.44) to support the use of the inferential methods used.

5.07 Conciseness in Tables Limit the content of your tables to essential materials. Tables with surplus elements

are less effective than lean tables. The principle of conciseness is relevant not only for

text tables but also for tables to be placed in online supplemental archives. Although

supplemental tables may be longer and more detailed than text tables, they must be

directly and clearly related to the content of the article (see section 2.13). Tables should be integral to the text but should be designed so that they can be understood

in isolation.

5.08 Table Layout The basic components of a prototypical table are shown in Table 5.1, including the

technical term, location, and definition of each element. Table layout should be logical and easily grasped by the reader. Table entries that

are to be compared should be next to one another. Following this principle, in gener-

al, different indices (e.g., means, standard deviations, sample sizes) should be segregat-

ed into different parts or lines of tables. Position variable and condition labels in close

proximity to the values of the variable to facilitate comparison. Table 5.2 illustrates

these principles. 1;

All tables are meant to show something specific; for example, tables that com- municate quantitative data are effective only when the data are arranged so that their meaning is obvious at a glance (Wainer, 1997). Often, the same data can be

arranged in different ways to emphasize different features of the data. In Table 5.3,

the same factor loading data are displayed in two different ways. The first example

emphasizes the factor structure of the two test batteries by keeping the subscales of

the batteries adjacent to each other. The second arrangement of the same data

5.09 Standard Forms Some data tables have certain standard (canonical) forms. The advantage of using the canonical form is that the reader generally knows where to look in the table for cer- tain kinds of information. In some situations, one may want to use a format other than

the canonical table form to make a specific point or to stress certain relationships. The

judicious use of nonstandard forms can be effective but must always be motivated by the special circumstances of the data array. When using nonstandard forms, make cer-

tain that labeling is extremely clear because most readers will assume that the canoni-

cal form is being used. Section 5.18 includes examples of standard tables for present-

ing several types of data.

5.10 Relation of Tables and Text Discussing tables in text. An informative table supplements—rather than dupli- cates—the text. In the text, refer to every table and tell the reader what to look for. Discuss only the table's highlights; if you find yourself discussing every item of the

table in the text, the table is unnecessary. Similarly, if additional tables are to be

included in online supplemental archives, mention their existence only briefly in the

print version of the article. Tables designated as supplemental materials must be accompanied by enough information to be completely understood on their own (see

section 2.13).

Citing tables. In the text, refer to tables by their number:

as shown in Table 8 the responses were provided by children with pretraining

Do not write "the table above" (or below) or "the table on page 32," because the posi- :t tion and page number of a table cannot be determined until the pages are typeset.

5.11 Relation Between Tables Consider combining tables that repeat data. Ordinarily, identical columns or rows of

data should not appear in two or more tables. Be consistent in the presentations of all

tables within a manuscript to facilitate comparisons. Use similar formats, titles, and

headings, and use the same terminology throughout (e.g., response time or reaction

time, not both).

5.12 Table Titles Give every table a brief but clear and explanatory title. The basic content of the table should be easily inferred from the title.

Too general:

Table 1

Relation Between College Majors and Performance [It is unclear what data are presented in the table.]

Too detailed:

Table 1

Mean Performance Scores on Test A, Test B, and Test C of Students With Psychology, Physics, English, and Engineering Majors [This duplicates informa- tion in the headings of the table.]

Good title:

Mean Performance Scores of Students With Different College Majors

Abbreviations that appear in the headings or the body of a table sometimes can be parenthetically explained in the table title.

Hit and False-Alarm (FA) Proportions in Experiment 2

Explain abbreviations that require longer explanations or that do not relate to the table title in a general note to the table (see section 5.16 and Table 5.2). Do not use a specific footnote to clarify an element of the title.

5.13 Table Headings A table classifies related items and enables the reader to compare them. Data form the body of the table. Headings establish your organization of the data and identify the columns of data beneath them. Like a table title, a heading should be brief and should not be many more characters in length than the widest entry.

Poor: Better:

Grade level Grade

You may use standard abbreviations and symbols for nontechnical terms (e.g., no.

L

for number, % for percent) and for statistics (e.g., M, SD, or any other abbrevia- tion in Table 4.4) in table headings without explanation. Abbreviations of technical terms, group names, and the like must be explained in the table title or in a note to the

TABLES

table (see section 5.12). Abbreviations may also be explained parenthetically following entries in the stub column.

Each column of a table must have a heading, including the stub column or stub, which is the leftmost column of the table (see Table 5.1 for illustration of technical terms). Subordination within the stub is easier to comprehend if you indent the stub items rather than create an additional column (e.g., Tables 5.4 and 5.5). The stub usu- ally lists the major independent or predictor variables. In Table 5.1, for instance, the stub lists the grades. Number elements only when they appear in a correlation matrix (see Table 5.6) or if they are referred to by number in text.

All headings identify items below them, not across from them. The headings just above the body of the table (called column heads and column spanners) identify the entries in the vertical columns in the body of the table. A column head covers just one column; a column spanner covers two or more columns, each with its own column

.01.

A few tables may require table spanners in the body of the table. These table span- ners cover the entire width of the body of the table, allowing for further divisions with- in the table (see Tables 5.1 and 5.15). Also, table spanners can be used to combine two tables provided they have identical column heads.

Any item within a column should be syntactically as well as conceptually comparable with the other items in that column, and all items should be described by the column head:

Condition Condition

Functional psychotic Functional psychosis

Drinks to excess Alcoholism

Character disorder Character disorder

Stub heads, column heads, and column spanners should be singular unless they refer to groups (e.g., Children), but table spanners may be plural. Capitalize only the first letter of the first word of all headings (column heads, column spanners, stub

5.14 Table Body Decimal values. The table body contains the data. Express numerical values to the number of decimal places that the precision of measurement justifies (see section 4.35), and if possible, carry all comparable values to the same number of decimal places. Empty cells. If the point of intersection between a row and a column (called a cell) can- not be filled because data are not applicable, leave the cell blank. If a cell cannot be filled because data were not obtained or are not reported, insert a dash in that cell and explain the use of the dash in the general note to the table. By convention, a dash in

• TABLES

the main diagonal position of a correlation matrix (see Table 5.6) indicates the corre-

lation of an item with itself, which must be 1.00, and is simply replaced by the dash.

If you need to explain that an element of a table is unavailable or inapplicable, use a

specific note rather than a dash (see section 5.16).

Participant trial trial Total M

1 5 7 12 6

The example could be improved by giving either the number of responses per trial

or the total number of responses, whichever is more important to the discussion, and

by not including the column with the mean because its calculation is simple.

5.15 confidence Intervals in Tables

When a table includes point estimates, for example, means, correlations, or regression

slopes, it should also, where possible, include confidence intervals. You may report

confidence intervals in tables either by using brackets, as in text (see section 4.10) and

in Table 5.8, or by giving lower and upper limits in separate columns, as in Table 5.9.

In every table that includes confidence intervals, state the confidence level, for exam-

ple, 95%. It is usually best to use the same confidence level throughout a paper.

5.16 Table Notes Tables may have three kinds of notes placed below

the body of the table: general notes,

specific notes, and probability notes. A general note qualifies, explains, or provides information

relating to the table as

a whole and ends with an explanation of any abbreviations, symbols, and the like.

Included within general notes would be any acknowledgments that a table is repro-

duced from another source. General notes are designated by the word Note (italicized)

followed by a period. (See Tables 5.1 and 5.4, among others.)

Note. Factor loadings greater than .45 are shown in boldface. M = match process;

N = nonmatch process.

A specific note refers to a particular column, row, or cell. Specific notes are indi-

cated by superscript lowercase letters (e.g., abc). Within the headings and table body,

order the superscripts from left to right and from top to bottom, starting at the top left.

Table notes, general or specific, apply only to that specific table and not to any other

table. Begin each table's first footnote with a superscript lowercase a (see Table 5.5).

'Four weight-related variables entered simultaneously. bAdjusted for race, socioeconomic status, and age group.

A probability note indicates how asterisks and other symbols are used in a table to indicate p values and thus the results of tests of statistical hypothesis testing. For results of statistical significance testing in text and tables, report the exact probabilities to two or three decimal places (e.g., p = .023 as opposed to p c .05; see Table 5.7 and section 4.35). When displaying the result in graphical modes (including certain tables such as tables of correlation matrices), it may be difficult to follow this recommendation with- out making the graphic unruly. Therefore, when displaying results graphically, revert to reporting in the "p <" style if using exact probabilities would make it difficult to comprehend the graphic. When discussing the results in the text, use exact probabili- ties regardless of the display mode. Include a probability note only when relevant to specific data within the table.

If the "p c" style is required, asterisks indicate ranges of p values. Assign the same number of asterisks from table to table within your paper, such as *p < .05, 0p < .01, and ***p < .001. Do not use any value smaller than ***p < .001.

If you need to distinguish between one-tailed and two-tailed tests in the same table, use an asterisk for the two-tailed p values and an alternate symbol (e.g., dagger) for the one-tailed p values.

To indicate statistically significant differences between two or more table entries— e for example, means that are compared with procedures such as a Tukey test—use low- ercase subscripts (see Table 5.7). Explain the use of the subscripts in the table note (see the following sample table notes).

Note. Means sharing a common subscript are not statistically different at a = .01 according to the Tukey HSD procedure.

Order the notes to a table in the following sequence: general note, specific note, probability note (see Table 5.1).

Note. The participants . . . responses.

Each type of note begins flush left (i.e., no paragraph indentation) on a new line below the table. The first specific note begins flush left on a new line under the gener- al note; subsequent specific notes are run in (lengthy specific notes may be set on sep- arate lines when typeset). The first probability note begins flush left on a new line; sub- sequent probability notes are run in.

Notes can be useful for eliminating repetition from the body of a table. Certain I types of information may be appropriate either in the table or in a note. To determine the placement of such material, remember that clearly and efficiently organized data enable the reader to focus on the data. Thus, if probability values or subsample sizes are numerous, use a column rather than many notes. Conversely, if a row or column con- tains few entries (or the same entry), eliminate the column by adding a note to the table:,'

5.17 Ruling of Tables Limit the use of rules (i.e., lines) in a table to those that are necessary for clarity. Appropriately positioned white space can be an effective substitute for rules; for exam-pie, long, uninterrupted columns of numbers or words are more readable if a horizontal line of space is inserted after every fourth or fifth entry. In the manuscript, use spacing between columns and rows and strict alignment to clarify relationships within a table.Tables may be submitted either single- or double-spaced. Consider the readabilityof the table during the review process in making your decision.

5.18 Presenting Data in Specific Types of Tables Complex experimental designs can be summarized in compact tables, making theentire structure of the experiment clear without the need for lengthy textual descrip- tions (see Table 5.4).

Important characteristics of a sample can be concisely summarized in a well-organ-ized table. Providing comparable census data can help the reader understand the gen-eralizability of the results (see Table 5.5). Key psychometric properties of the major variables can be easily summarized in atable (see Table 5.10). Clearly state the index of reliability (or other psychometricproperty) being used and the sample on which the reliability was based (if differentfrom the study sample). Table 5.11 shows one-degree-offreedom within-subject contrasts within a largerset of effects, including both confidence intervals and effect sizes. In Table 5.6, note the

compact, yet information-packed, form in which the intercorrelations among the vari-ables for two different groups are presented in the same table—one group below the main diagonal, the other above the main diagonal. Means and standard deviations forthe two groups are similarly positioned, with the Group 1 means and standard devia-tions given in the last two data columns and those for Group 2 in the last two datarows. Construction of a correlation matrix of this type not only is concise in terms ofthe amount of page space used but also makes the visual comparison of correlational elements much easier.

Clearly label the type of regression (e.g., hierarchical) and type of regression coef-ficients (raw or standardized) being reported (see Tables 5.12 and 5.13). For hierarchi-cal and other sequential regressions, be sure to provide the increments of change (seesection 4.44). In model-comparison tables, ensure that the competing models are clearly identi-fied and that the comparisons are clearly specified. Comparative fit indices can be use-ful for the reader (see Tables 5.14 and 5.15).

Because there is so much violence in the big city. . You know your town and peo- ple and you trust each other like family.

Better to live in a big city because there are more jobs and educational opportunities.

I agree that life in a small town is better because in a small town life is more peaceful.

There is less gang activity and overall life is more peaceful.

Sometimes it is true that rural life is better. However, it's also true that a big city can help you or can destroy you; that depends on you.

Figures

There are many different types of figures; however, certain principles are the same for all figure types. The first consideration is the information value of the figure in the text of the paper in which it is to appear. If the figure does not add substantively to the .1 understanding of the paper or duplicates other elements of the paper, it should not be>

Table Checklist

LI Is the table necessary?

LI Does it belong in the print version of the article, or can it go in an online sup- plemental file?

LI Are all comparable tables in the manuscript consistent in presentation?

LI Is the title brief but explanatory?

LI Does every column have a column head?

LI Are all abbreviations explained, as well as special use of italics, parentheses, italics, dashes, boldface, and special symbols?

LI Are the notes in the following order: general note, specific note, probability note?

LI Are all vertical rules eliminated?

LI Are confidence intervals reported for all major point estimates? Is the confi- dence level—for example, 95%—stated, and is the same level of confidence used for all tables and throughout the paper?

LI If statistical significance testing is used, are all probability level values correct- ly identified? Are asterisks attached to the appropriate table entries only when needed (as opposed to stating exact probabilities)? When used, is a probability level assigned the same number of asterisks in all tables in the same paper?

LI If all or part of a copyrighted table is reproduced or adapted, do the table notes give full credit to the copyright owner? Have you received written per- mission for reuse (in print and electronic form) from the copyright holder and sent a copy of that written permission to the journal editor with the ¶nal ver- sion of your paper?

inc!uded. A second consideration is whether a figure is the best way to communicate the information. In some cases (particularly when quantitative information is being conveyed), a table may offer more precision than, say, a graph. A third consideration is the degree to which the figure can be produced in a way that captures the essential information features desired without visually distracting detail. When considering inclusion of a figure, always remember that the information value of the figure must dominate other decisions. If you focus on the principle of information value, other questions—for example, use of color, use of photographic images, or magnitude of cropping of a picture—should be relatively easy to resolve.

As with other elements of a manuscript, you may wish to consider placing some figures in online supplemental materials archives when those are available. Figures placed in online supplemental materials archives are those that would enrich the understanding of the material presented in the print version of the article but are not essential to the basic understanding of the material. You might want also to include materials that cannot be displayed in print format, such as video clips. As with other online supplemental materials, figures must be able to be understood on their own (see section 2.13). Therefore label them clearly and use detailed legends.

5.21 Types of Figures Many types of figures can be used to present data to the reader. Sometimes the choice of which type to use will be obvious; at other times it will not. The more common types of figures used are described next.

• Graphs typically display the relationship between two quantitative indices or between a continuous quantitative variable (usually displayed as the y axis) and groups of subjects displayed along the x axis.

• Charts generally display nonquantitative information such as the flow of subjects through a process, for example, flow charts.

• Maps generally display spatial information. • Drawings show information pictorially. • Photographs contain direct visual representations of information.

Although these are general prototypes, there are many variations and versions of each, and the distinctions among many of them are not cleat Computer-generated images can be made to seem as if they are life-reflecting photographs, and photographs can be engineered to look more like drawings. Whenever photographic images are changed in a way that their basic information is modified, you must disclose the manipulation (see section 5.29).

Figures can be effectively used to illustrate complex theoretical formulations (see Figure 5.1) or to represent a theory graphically through a set of path models (see Figure 5.2). They can also show the sampling and flow of subjects through a random- ized clinical trial or other experiment (see Figure 5.3) or the flow of participants in a survey study (see Figure 5.4). Figures can be used to illustrate the results of a one-way design with error bars representing precision of the resulting estimates (see Figure 5.5) or empirical results from a complex multivariate model (see Figure 5.6). They can also show details concerning the kinds of responses being gathered and scoring methods (see Figure 5.7) as well as details of an experimental laboratory set-up (see Figure 5.8) and an experimental procedure (see Figure 5.9).

Legends. The legend is an integral part of the figure; therefore, it should have the same kind and proportion of lettering that appear in the rest of the figure. Capitalize major words in the legend.

Captions. The caption serves both as an explanation of the figure and as a figure title; therefore, the figure itself should not include a title. The caption should be a brief but descriptive phrase. Compare the following captions.

After the descriptive phrase, add any information needed to clarify the figure: A reader should not have to refer to the text to decipher the figure's message. Always explain units of measurement, symbols, and abbreviations that are not included in the legend. If your graph includes error bars, explain whether they represent standard deviations, standard errors, confidence limits, or ranges; it is also helpful to display sample sizes. If statistically significant values are marked in the figure, explain the probability in the caption (follow the same system used for table notes; see section 5.16). Include within the caption any acknowledgment that a figure is reproduced from another source (see section 2.12).

Make certain that the symbols, abbreviations, and terminology in the caption and legend agree with the symbols, abbreviations, and terminology in the figure, in other figures in the article, and in the text.

5.24 Planning Figures When planning a figure, consider the following guidelines:

• Parallel figures or figures of equal importance should be of equal size and scale. • Like figures should be combined to facilitate comparisons between them. For exam-

ple, two figures can be placed one above the other and treated as one figure. Two line graphs with identical axes might be combined horizontally and treated as one figure.

• A figure legend should be positioned within the borders of the figure (see Figure 5.5). Place labels for parts of a figure as close as possible to the components being identified.

5.25 Preparation of Figures Figures intended for publication in scholarly journals should be computer generated using professional-level graphic software. Always check the file type requirements of the publisher to which you intend to submit your paper. Figures should be prepared at a resolution sufficient to produce high-quality images; appropriate resolution depends on figure type. Photographs (see section 5.29), for example, can be reproduced clear- ly at lower resolution than that needed for line art.

Image dimensions should be such that files can be easily transferred electronically. Avoid the use of three-dimensional and other effects (including color), except in rare instances in which they demonstrably enhance the presentation of your data. Individual publishers have stated policies with regard to color printing. Size and proportion of elements. Each element must be large enough and sharp enough to be legible. Use a simple typeface (such as Anal, Futura, or Helvetica) with enough space between letters to avoid crowding. Letters should be clear, sharp, and uniformly dark and should be sized consistently throughout the figure. Type style affects legibili- ty. For example, boldface type tends to thicken and become less readable. The size of lettering should be no smaller than 8 points and no larger than 14 points. As a general guideline, plot symbols should be about the size of a lowercase letter of an average label within the figure. Also consider the weight (i.e., size, density) of each element in a fig- ure in relation to that of every other element, making the most important elements the most prominent. For example, curves on line graphs and outlines of bars on bar graphs should be bolder than axis labels, which should be bolder than the axes and tick marks. Shading. Limit the number of different shadings used in a single graphic. If different shadings are used to distinguish bars or segments of a graph, choose shadings that are distinct (e.g., the best option to distinguish two sets of bars is no shading [openJ and black fsolidj). If more than three shadings are required, a table may be a better pres- entation of the data. Use computer-generated art in such a way as to maximize the clar- ity of the resulting graphic. And as always, keep it simple and clean looking.

Presenting Electrophysiological, Radiological, and Other Biological Data The presentation of electrophysiological and radiological data presents special chal- lenges because of both the complexity of the data and the lack of existence of a

PRESENTING OTHER BIOLOGICAL DATA

single convention for presentation of these types of data. The lack of a single, well- established standard for presentation requires that labeling of all aspects of the presentation be done clearly and completely (readers are referred to Devlin & Poldrack, 2007; Mildenberger, Eichenberg, & Martin, 2002; Picton et al., 2000; see also http://www.fmrimethods.org). Do not assume that readers will know the conven- tion that you are following. In addition, most graphical and image-based representa- tions of the basic data are highly processed, edited, and enhanced. The high level of processing of these forms of data makes it essential that the processing methods are clearly identified and that enhanced data (and the ensuing representation of such enhanced data) are clearly and openly identified.

In selecting data elements to present in the print version of the document, focus first on principles of clarity of representation, necessity for understanding, and coher- ence among representations. With the availability of online supplemental archives, carefully consider the readability of the text when deciding whether to include com- plex graphs and images in the text proper. When materials are better viewed in non- print media or when images and graphics contain more information than can easily be comprehended in the usual print formats—for example, those that are greatly enhanced through the use of color or instances in which numerous images are needed to communicate the essential features of the study—consider the use of online supple- mental archives for the presentation of the bulk of this information.

Many procedures used for the display of biologically related data use color, motion, or other display features not best rendered in black-and-white printing. In par- ticular, fMRI images are typically coded in color, where color differences indicate acti- vation differences. In the genetics area, gene staining results are often presented in color. Dynamical spread of brain activation can be displayed through color video clips. In the material that follows, we present print examples that are appropriate for black- and-white printing but also point to a number of examples (particularly those using color) that are included on the APA Style website (www.apastyle.org).

5.26 Electrophysiological Data When presenting electrophysiological data, clear labeling is essential; for example, in the presentation of event-related brain potential data, it is essential that the direction of negativity (i.e., negative up or down) be indicated as well as the scale of the response. Information that is necessary for proper interpretation of the graphic, such as number or placement of electrodes, should accompany the graphic display. The graphic image and the points made in the text should be closely allied. Eliminate extra- neous materials from graphic presentation (see Figure 5.10).

5.27 Radiological (Imaging) Data When presenting brain images, clearly label each image. When axial or coronal sec- tions are being displayed, clearly label which hemisphere is the left and which the right. When saggital slices are displayed, clearly indicate whether each slice is of the right or the left hemisphere. When slices are shown, show also an image that indicates where the slices were taken to help orient the reader. Specify the coordinate space in which] the images have been normalized (e.g., Talairach, MNI).

Cutaway views of the brain that show activations interior to it can be useful if the cutaways clearly depict the tissue that has been excised. When activations are super-imposed on a surface-rendered image of a brain, include a clear explanation of whatactivations are being shown, particularly with regard to the depth of the activationthat has been brought to the surface; the use of flattened surface images may helpmake the data clearer. When using color, use it consistently in all representations within the document and clearly specify the color—scale mapping (see example atwww.apastyle.org).

Neuroimaging data almost always require extensive postacquisition processing.Details of the processing methods should accompany their display (see Figure 5.11).Photomicrographs are often used in cell-staining and other types of imaging stud-ies. When preparing photomicrographs, include a scale bar and staining materialsinformation in the figure caption.

5.28 Genetic Data As with other displays of biological material, clear labeling enhances the display ofgenetic information such as deletion patterns—be they of the physical map variety(see Figure 5.12) or the photographic stain variety (see example at www.apastyle.org).

Genetic data displays often contain much information; care-ful editing of the image, and of its legend, can improve the communicative value ofthe figure.

5.29 Photographs Photographic images are almost always submitted as digital files embedded in orattached to the electronic version of the manuscript. It is essential that these images besubmitted at appropriate levels of resolution.

Because reproduction softens contrast and detail in photographs, starting with richcontrast and sharp prints will improve the final print version of the image. The cam-era view and the lighting should highlight the subject and provide high contrast; a lightor dark background can provide even more contrast. Photographs must be of professional quality and should be presented as black-and-white images, unless they include color-specific information relevant to the study (e.g.,differently colored stimuli). Submit the image as a file type appropriate to the needs ofthe publication to which you are submitting. Do not submit color image files for fig-ures intended for black-and-white printing; the transition from color to black andwhite for reproduction is unpredictable and can result in misleading images.

as a means of scientific communication; they also help to protect the identity of indi- viduals. However, the same technology can be used to deceive. Ethical principles of publication forbid any intentional misrepresentation of images in exactly the same way that fraudulent data manipulation is forbidden. When an image that might reasonably be thought to be a photographic image (as opposed to an image that is clearly a con- structed image—a table, chart, cartoon, etc.) has been altered in a manner beyond sim- ple cropping, clearly indicate in a note that accompanies the image that it has been altered.

If you photograph a person, obtain a signed release from that person to use the photograph. If you use a photograph from another source, try to obtain the original photograph because photographs of photographs do not print clearly. Obtain written I permission for reuse (in both print and electronic form) from the copyright holder, and acknowledge the author and the copyright holder in the figure caption (see section 5.06; see also section 2.12). You may need to obtain permission from the photogra- pher as well because professional photographs do not meet all the criteria of work for hire and are usually the property of the photographer.

Crediting Sources

S cientific knowledge represents the accomplishments of many researchers over time. A critical part of the writing process is helping readers place your contribu- tion in context by citing the researchers who influenced you. In this chapter, we

provide the ground rules for acknowledging how others contributed to your work. We begin by describing the appropriate level of citation and offer a brief review of plagia- rism and self-plagiarism. Next, we offer guidelines on formatting quoted material in text and information on seeking permission to reprint or adapt previously published material. This is followed by instruction on citing sources in text and a description of key elements of the reference list.

When to Cite Cite the work of those individuals whose ideas, theories, or research have directly influenced your work. They may provide key background information, support or dis- pute your thesis, or offer critical definitions and data. Citation of an article implies that you have personally read the cited work. In addition to crediting the ideas of others that you used to build your thesis, provide documentation for all facts and figures that are not common knowledge. Figure 6.1 provides an example of the appropriate level of citation, adapted from an article in an APA journal.

The number of sources you cite in your work will vary by the intent of the article. For most articles, aim to cite one or two of the most representative sources for each key point. However, because the intent of a review article is to acquaint readers with all that has been written on a topic, authors of literature reviews typically include a more exhaustive list of citations.

6.01 Plagiarism As stated in Chapter 1, "Authors do not present the work of another as if it were their own work" (p. 16). Whether paraphrasing, quoting an author directly, or describing an idea that influenced your work, you must credit the source. To avoid charges of pla- giarism, take careful notes as you research to keep track of your sources and cite those sources according to the guidelines presented in this chapter (see also section 1.10).

6.02 Self-Plagiarism Whereas plagiarism refers to the practice of claiming credit for the words, ideas, and con- cepts of others, self-plagiarism refers to the practice of presenting one's own previously published work as though it were new. As noted in Chapter 1, "The core of the new doc- ument must constitute an original contribution to knowledge, and only the amount of previously published material necessary to understand that contribution should be included, primarily in the discussion of theory and methodology" (p 16) Avoid charges of self-plagiarism by familiarizing yourself with the ethical standards regarding duplicate publication and the legal standards of fair use (see also section 1.10).

Quoting and Paraphrasing 6.03 Direct Quotation of Sources Reproduce word for word material directly quoted from another author's work or from your own previously published work, material replicated from a test item, and verbatim instructions to participants. When quoting, always provide the author, yea; and specific page citation or paragraph number for nonpaginated material (see sec- tion 6.05) in the text and include a complete reference in the reference list (see Citing References in Text, p. 174, for exceptions to this rule).

If the quotation comprises fewer than 40 words, incorporate it into text and enclose the quotation with double quotation marks. If the quotation appears in mid-

Example of Appropriate Citation Level

Left-handers make up 8% to 13% of most human populations, with left-handedness more common in men than in women (Gilbert & Wysocki, 1992; McManus, 1991). Secondary school and university students engaged in "interactive" sports such as tennis and basket- ball are significantly more likely to be left-handed than those engaged in "noninteractive" sports such as swimming or rowing, or than those in the general population (Grouios, Tsorbatzoudis, Alexandris, & Barkoukis, 2000; Raymond et al., 1996). One possible explanation for this handedness bias is that left-handers are better than right-handers at some visuomotor tasks, as has been invoked to explain the left-handed bias among elite tennis players (Holtzen, 2000).

sentence, end the passage with quotation marks, cite the source in parentheses imme-diately after the quotation marks, and continue the sentence. Use no other punctuationunless the meaning of the sentence requires such punctuation.

Interpreting these results, Robbins et al. (2003) suggested that the "therapistsin dropout cases may have inadvertently validated parental negativity about the adolescent without adequately responding to the adolescent's needs or con-cerns" (p. 541), contributing to an overall climate of negativity.

If the quotation appears at the end of a sentence, close the quoted passage with quo-tation marks, cite the source in parentheses immediately after the quotation marks,and end with a period or other punctuation outside the final parenthesis.

Confusing this issue is the overlapping nature of roles in palliative care, whereby"medical needs are met by those in the medical disciplines; nonmedical needsmay be addressed by anyone on the team" (Csikai & Chaitin, 2006, p. 112). If the quotation comprises 40 or more words, display it in a freestanding block of textand omit the quotation marks. Start such a block quotation on a new line and indentthe block about a half inch from the left margin (in the same position as a new para-graph). If there are additional paragraphs within the quotation, indent the first line ofeach an additional half inch. Double-space the entire quotation. At the end of a blockquotation, cite the quoted source and the page or paragraph number in parenthesesafter the final punctuation mark,

Others have contradicted this view: Co-presence does not ensure intimate interaction among all group mem- bers. Consider large-scale social gatherings in which hundreds or thousandsof people gather in a location to perform a ritual or celebrate an event.

In these instances, participants are able to see the visible manifestation of the group, the physical gathering, yet their ability to make direct, intimateconnections with those around them is limited by the sheer magnitude ofthe assembly. (Purcell, 1997, pp. 111—112)

Alternatively, if the quoted source is cited in the sentence introducing the block quote(e.g., "In 1997, Purcell contradicted this view .."), only the page or paragraph num-ber is needed at the end of the quotation.

6.04 Paraphrasing Material When paraphrasing or referring to an idea contained in another work, you are encour-aged to provide a page or paragraph number, especially when it would help an inter-ested reader locate the relevant passage in a long or complex text.

paragraph numbers are visible, use them in place of page numbers. Use the abbre-

viation para.

Basu and Jones (2007) went so far as to suggest the need for a new "intellectual

framework in which to consider the nature and form of regulation in cyberspace"

(para. 4).

If the document includes headings and neither paragraph nor page numbers are visible, cite the heading and the number of the paragraph following it to direct the

reader to the location of the quoted material.

In their study, Verbunt, Pernot, and Smeets (2008) found that "the level of perceived

disability in patients with fibromyalgia seemed best explained by their mental health

condition and less by their physical condition" (Discussion section, para. 1).

In some cases in which no page or paragraph numbers are visible, headings may be too

unwieldy to cite in full. Instead, use a short title enclosed in quotation marks for the

parenthetical citation:

"Empirical studies have found mixed results on the efficacy of labels in educat-

ing consumers and changing consumption behavior" (Golan, Kuchler, & Krissof,

2007, "Mandatory Labeling Has Targeted," para. 4).

(The heading was "Mandatory Labeling Has Targeted Information Gaps and Social

Objectives.")

6.06 Accuracy of Quotations (

Direct quotations must be accurate, Except as noted here and in sections 6.07 and 6.08, the quotation must follow the wording, spelling, and interior punctuation of the

original source, even if the source is incorrect. If any incorrect spelling, punctuation, or grammar in the source might confuse read-

ers, insert the word sic, italicized and bracketed, immediately after the error in the quo' r

tation. (See sections 4.08 and 4.10 regarding the use of brackets in quotations.) Always check the manuscript copy against the source to ensure that there are no discrepancies.

6.07 Changes From the Source Requiring No Explanation The first letter of the first word in a quotation may be changed to an uppercase or a lowercase letter. The punctuation mark at the end of a sentence may be changed to fit t

the syntax. Single quotation marks may be changed to double quotation marks and

vice versa. Any other changes (e.g., italicizing words for emphasis or omitting

see section 6.08) must be explicitly indicated.

that you have omitted material from the original source. Use four points to

any omission between two sentences. The first point indicates the period at the end of the first sentence quoted, and the three spaced ellipsis points follow. Do not use ellip- sis points at the beginning or end of any quotation unless, to prevent misinterpretation,, you need to emphasize that the quotation begins or ends in midsentence.

Inserting material. Use brackets, not parentheses, to enclose material such as an addi- tion or explanation inserted in a quotation by some person other than the original author (see also the second example in section 4.10).

"They are studying, from an evolutionary perspective, to what extent [children's] play is a luxury that can be dispensed with when there are too many other com- peting claims on the growing brain (Henig, 2008, p. 40).

Adding emphasis. If you want to emphasize a word or words in a quotation, italicize the word or words. Immediately after the italicized words, insert within brackets the words emphasis added, that is, [emphasis added] (see section 4.08, second example).

6.09 Citations Within Quotations Do not omit citations embedded within the original material you are quoting. The works cited need not be included in the list of references (unless you happen to cite them as primary sources elsewhere in your paper).

"In the United States, the American Cancer Society (2007) estimated that about 1 million cases of NMSC and 59,940 cases of melanoma would be diagnosed in 2007, with melanoma resulting in 8,110 deaths" (Miller et al., 2009, p. 209).

6.10 Permission to Quote, Reprint, or Adapt • You may need written permission from the owner of copyrighted work if you include

lengthy quotations or if you include reprinted or adapted tables or figures. Reprinting indicates that the material is reproduced exactly as it appeared originally, without mod- ifications, in the way in which it was intended Adaptation refers to the modification of material so that it is suitable for a new purpose (e g, paraphrasing or presenting an original theory or idea discussed in a long passage in a published article in a new way that suits your study; using part of a table or figure in a new table or figure in your man- uscript) Requirements for obtaining permission to quote copyrighted material vary from one copyright owner to another; for example, APA policy permits authors to use, with some exceptions, a maximum of three figures or tables from a journal article or book chapter, single text extracts of fewer than 400 words, or a series of text extracts

that total fewer than 800 words without requesting formal permission from APA. It is important to check with the publisher or copyright owner regarding specific require- ments for permission to quote from or adapt copyrighted material.

It is the author's responsibility to find out whether permission is required from the copyright owner and to obtain it for both print and electronic reuse. APA cannot pub- lish previously copyrighted material that exceeds the copyright holder's determination of "fair use" without permission.

If you must obtain written permission from the copyright owner, append a foot- note to the quoted material with a superscript number, and in the footnote acknowl-

edge permission from the owner of the copyright. Format the footnote as shown in Chapter 2, section 2.12.

Citing References in Text References in APA publications are cited in text with an author—date citation system and are listed alphabetically in the reference list. This style of citation briefly identifies the source for readers and enables them to locate the source of information in the alphabetical reference list at the end of the article. Each reference cited in text must appear in the reference list, and each entry in the reference list must be cited in text. Make certain that each source referenced appears in both places and that the text cita- tion and reference list entry are identical in spelling of author names and year.

However, two kinds of material are cited only in the text: references to classical works such as the Bible and the Qur'an, whose sections are standardized across edi- tions, and references to personal communications (see sections 6.18 and 6.20). References in a meta-analysis are not cited in text unless they are also mentioned in the text (see section 6.26)

6.11 One Work by One Author The author—date method of citation requires that the surname of the author (do not include suffixes such as Jr.) and the year of publication be inserted in the text at the appropriate point:

Kessler (2003) found that among epidemiological samples Early onset results in a more persistent and severe course (Kessler. 2003).

If the name of the author appears as part of the narrative, as in the first example, cite only the year of publication in parentheses. Otherwise, place both the name and the year, separated by a comma, in parentheses (as in the second example). Even if the reference includes month and year, include only the year in the text citation. In the rare case in which both the year and the author are given as part of the textual discussion, do not add parenthetical information:

In 2003, Kessler's study of epidemiological samples showed that

Within a paragraph, when the name of the author is part of the narrative (as in the first example above), you need not include the year in subsequent nonparenthetical ref- erences to a study as long as the study cannot be confused with other studies cited in the article. Do include the year in all parenthetical citations:

Among epidemiological samples, Kessler (2003) found that early onset social anxiety disorder results in a more potent and severe course. Kessler also found. . . . The study also showed that there was a high rate of comorbidity with alcohol abuse or dependence and major depression (Kessler, 2003).

However, when both the name and the year are in parentheses (as in the second: example above), include the year in subsequent citations within the paragraph:

Early onset results in a more persistent and severe course (Kessler, 2003). Kessler (2003) also found.

6.12 One Work by Multiple Authors When a work has two authors, cite both names every time the reference occurs in text.When a work has three, foui or five authors, cite all authors the first time the refer-ence occurs; in subsequent citations, include only the surname of the first author fol- lowed by at at. (not italicized and with a period after al) and the year if it is the first citation of the reference within a paragraph.

Kisangau, Lyaruu, Hosea, and Joseph (2007) found [Use as first citation in text.] Kisangau et ai. (2007) found [Use as subsequent first citation per paragraph thereafter.]

Kisangau et ai. found [Omit year from subsequent citations after first nonpar- enthetical citation within a paragraph. Include the year in subsequent citationsif first citation within a paragraph is parenthetical. See section 6.11.]

Exception: If two references of more than three surnames with the same year shortento the same form (e.g., both Ireys, Chernoff, DeVet, & Kim, 2001, and Ireys, Chernoff,Stein, DeVet, & Silver, 2001, shorten to Ireys et al., 2001), cite the surnames of the firstauthors and of as many of the subsequent authors as necessary to distinguish the tworeferences, followed by a comma and at at.

keys, Chernoff, DeVet, et al. (2001) and Ireys, Chernoff, Stein, et al. (2001)

Precede the final name in a multiple-author citation in running text by the wordand. In parenthetical material, in tables and captions, and in the reference list, join thenames by an ampersand (&):

as Kurtines and Szapocznik (2003) demonstrated as has been shown (Jöreskog & Sorbom, 2007)

When a work has six or more authors, cite only the surname of the first author fol-lowed by at at. (not italicized and with a period after al) and the year for the first andsubsequent citations. (See section 6.27 and Example 2 in Chapter 7 for how to cite workswith more than six authors in the reference list.) If two references with six or moreauthors shorten to the same form, cite the surnames of the first authors and of as manyof the subsequent authors as necessary to distinguish the two references, followed by acomma and at at. For example, suppose you have entries for the following references:

Kosslyn, Koenig, Barrett, Cave, Tang, and Gabrieli (1996) Kosslyn, Koenig, Gabrieli, Tang, Marsolek, and Daly (1996)

In text you would cite them, respectively, as

I CITING REFERENCES IN TEXT

Table 6.1 illustrates the basic citation styles. Exceptions and citation styles that do not work in the tabular format are discussed in text or included as part of the example references.

6.13 Groups as Authors The names of groups that serve as authors (e.g., corporations, associations, govern- ment agencies, and study groups) are usually spelled out each time they appear in a text citation. The names of some group authors are spelled out in the first citation and abbreviated thereafter. In deciding whether to abbreviate the name of a group author, use the general rule that you need to give enough information in the text citation for the reader to locate the entry in the reference list without difficulty. If the name is long and cumbersome and if the abbreviation is familiar or readily understandable, you may abbreviate the name in the second and subsequent citations. If the name is short or if the abbreviation would not be readily understandable, write out the name each time it occurs (see examples in Table 6.1).

6.14 Authors With the Same Surname If a reference list includes publications by two or more primary authors with the same surname, include the first author's initials in all text citations, even if the year of pub- lication differs. Initials help the reader to avoid confusion within the text and to locate the entry in the list of references (see section 6.25 for the order of appearance in the reference list).

Arrange two or more works by the same authors (in the same order) by year of publication. Place in-press citations last. Give the authors' surnames once; for each subsequent work, give only the date.

Training materials are available (Department of Veterans Affairs, 2001, 2003)

Past research (Gogel, 1990, 2006, in press)

Identify works by the same author (or by the same two or more authors in the same order) with the same publication date by the suffixes a, b, c, and so forth, after the year; repeat the year. The suffixes are assigned in the reference list, where these kinds of references are ordered alphabetically by title (of the article, chapter, or com- plete work).

Several studies (Derryberry & Reed, 2005a, 2005b, in press-a; Rothbart, 2003a,

2003b)

List two or more works by different authors who are cited within the same paren- theses in alphabetical order by the first author's surname. Separate the citations with semicolons.

Several studies (Miller, 1999; Shafranske & Mahoney, 1998)

Exception: You may separate a major citation from other citations within parentheses by inserting a phrase, such as see also, before the first of the remaining citations, which should be in alphabetical order:

(Minor, 2001; see also Adams, 1999; Storandt, 2007)

6.17 Secondary Sources Use secondary sources sparingly, for instance, when the original work is out of print, unavailable through usual sources, or not available in English. Give the secondary source in the reference list; in text, name the original work and give a citation for the secondary source. For example, if Aliport's work is cited in Nicholson and you did not read Allport's work, list the Nicholson reference in the reference list. In the text, use the following citation:

Allport's diary (as cited in Nicholson, 2003).

6.18 Classical Works When a date of publication is inapplicable, such as for some very old works, cite the year of the translation you used, preceded by trans., or the year of the version you used,

followed by version. When you know the original date of publication, include it in thej citation.

Reference list entries are not required for major classical works, such as ancientGreek and Roman works or classical religious works; simply identify in the first cita- tion in the text the version you used. Parts of classical works (e.g., books, chapters, verses, lines, cantos) are numbered systematically across all editions, so use these num-bers instead of page numbers when referring to specific parts of your source:

1 Cor. 13:1 (Revised Standard Version) (Qur'an 5:3—4)

6.19 Citing Specific Parts of a Source To cite a specific part of a source, indicate the page, chapter, figure, table, or equation at the appropriate point in text. Always give page numbers for quotations (see section 6.03). Note that page, but not chapter, is abbreviated in such text citations:

(Centers for Disease Control and Prevention, 2005, p. 10) (Shimamura, 1989, Chapter 3)

For guidance on citing electronic sources that do not provide page numbers, seesection 6.05. See section 6.18 for citing parts of classical works.

6.20 Personal Communications Personal communications may be private letters, memos, some electronic communica- tions (e.g., e-mail or messages from nonarchived discussion groups or electronic bul- letin boards), personal interviews, telephone conversations, and the like. Because they do not provide recoverable data, personal communications are not included in the ref- erence list. Cite personal communications in text only, Give the initials as well as the surname of the communicator, and provide as exact a date as possible:

Use your judgment in citing other electronic forms as personal communications; online networks currently provide a casual forum for communicating, and what you cite should have scholarly relevance,

Some forms of personal communication are recoverable, and these should be ref- erenced as archival materials. See section 7.10 for templates, descriptions, and exam- ples of archival sources in the reference list.

6.21 Citations in Parenthetical Material In a citation that appears in parenthetical text, use commas, not brackets, to set offthe date:

(see Table 3 of U.S. Department of Labor, 2007, for complete data)

REFERENCE LIST

Reference List The reference list at the end of a journal article provides the information necessary to identify and retrieve each source. Choose references judiciously and include only the sources that you used in the research and preparation of the article. APA journals and other journals using APA Style generally require reference lists, not bibliographies.1 APA requires that the reference list be double-spaced and that entries have a hanging indent. Because a reference list includes only references that document the article and provide recoverable data, do not include in the list personal communications, such as letters, memoranda, and informal electronic communications. Instead, cite personal communications only in text (see section 6.20 for format).

6.22 Construction of an Accurate and Complete Reference List Because one purpose of listing references is to enable readers to retrieve and use the sources, reference data must be correct and complete. Each entry usually contains the following elements: author, year of publication, title, and publishing data—all the information necessary for unique identification and library search. The best way to ensure that information is accurate and complete is to check each reference carefully against the original publication. Give special attention to spelling of proper names and of words in foreign languages, including accents or other special marks, and to com- pleteness of journal titles, years, volume and issue numbers, page numbers, and elec- tronic retrieval data. Authors are responsible for all information in their reference lists. Accurately prepared references help establish your credibility as a careful researcher.

Abbreviations. Acceptable abbreviations in the reference list for parts of books and other publications include the following:

Abbreviation Book or publication part ed. edition Rev. ed. Revised edition 2nd ed. second edition Ed. (Eds.) Editor (Editors) Trans. Translator(s)

nd. no date p. (pp.) page (pages)

Vol. Volume (as in Vol. 4) Vols. Volumes (as in Vols. 1—4)

No. Number Pt. Part

Tech. Rep. Technical Report Suppl. Supplement

Arabic numerals. Although some volume numbers of books and journals are given Roman numerals, APA journals use Arabic numerals (e.g., Vol. 3, not Vol. III) they use less space and are easier to comprehend than Roman numerals. A Roman numeil al that is part of a title should remain Roman (e.g., Attention and Performance XIII). I

'Note that a reference list cites works that specifically support a particular article. In contrast, a bibliography works for background or for further reading and may include descriptive notes.

6.23 Consistency Consistency in reference style is important, especially in light of evolving technologiesin database indexing, such as automatic indexing by database crawlers. These com-puter programs use algorithms to capture data from primary articles as well as fromthe article reference list. If reference elements are out of order or incomplete, the algo-rithm may not recognize them, lowering the likelihood that the reference will be cap-tured for indexing. With this in mind, follow the general formats for placement of dataand use the electronic reference guidelines detailed in this chapter to decide which dataare necessary to allow readers to access the sources you used.

6.24 Using the Archival Copy or Version of Record When using information and data retrieved online, check to see whether you are citingthe appropriate version of your reference source. In-progress and final versions of thesame work might coexist on the Internet, which can present challenges in determiningwhich version is most current and most authoritative. In most cases, it is best to citethe archival version or version of record, which has been peer-reviewed and may pro-vide additional links to online supplemental material. If the most current version avail-able was an advance release version at the time that you originally cited it, recheck thesource and update its publication status as close as possible to the publication date ofyour work (see section 6.32).

6.25 Order of References in the Reference List The principles for arranging entries in a reference list are described next. You may alsofind it helpful to look at the reference list in Chapter 2 in the sample manuscript andat reference lists in journals that are published in APA Style. Alphabetizing names. Arrange entries in alphabetical order by the surname of the firstauthor followed by initials of the author's given name, and use the following rules forspecial cases:

• Alphabetize by the author's surname. This surname/given name formula is com-monly used in Western countries but is less commonly used in many Eastern coun-tries. If you are uncertain about the proper format for a name, check with the authorfor the preferred form or consult the author's previous publication for the common-ly used form (e.g., Chen Zhe may publish under Zhe Chen in the United Staçes).• Alphabetize letter by letter. When alphabetizing surnames, remember that "nothingprecedes something": Brown, J. R., precedes Browning, A. R., even though i pre-cedes fin the alphabet.

Singh, Y., precedes Singh Sjddhu N. LOpez, M. F., precedes Lopez de Molina, G. Ibn Abdijlazjz T., precedes lbn Nidal, A. K. M. Girard, J.-B., precedes Girard-Perregaux A. S. Villafuerte, S. A., precedes VilIa-Lobos, 3. Benjamin, A. S., precedes ben Yaakov, D.

• Alphabetize the prefixes M', Mc, and Mac literally, not as if they were all spelled Mac. Disregard the apostrophe: MacArthur precedes McAllister, and MacNeil pre- cedes M'Carthy.

• Alphabetize. entries with numerals chronologically (e.g., Macomber, J., II, precedes Macomber, J., Ill).

Order of several works by the same first author. When ordering several works by the same first author, give the author's name in the first and all subsequent references, and use the following rules to arrange the entries:

• One-author entries by the same author are arranged by year of publication, the ear- liest first:

Upenieks, V. (2003).

Upenieks, V. (2005).

• One-author entries precede multiple-author entries beginning with the same sur- name (even if the multiple-author work was published earlier):

Alleyne, R. L. (2001).

Alleyne, R. L., & Evans, A. J. (1999).

• References with the same first author and different second or arranged alphabetically by the surname of the second author or, if is the same, the surname of the third author, and so on:

Boockvar, K. S., & Burack, 0. R. (2007).

Boockvar, K. S., Carison LaCorte, H., Giambanco, V., Friedman, (2006).

D., Firsching, A., & Brown, J. (1999).

Hayward, D., Firsching, A., & Smigel, J. (1999).

• References with the same authors in the same order are arranged by year of publi- cation, the earliest first:

Cabading, J. R., & Wright. K. (2000).

Cabading, J. R., & Wright. K. (2001).

• References by the same author (or by the same two or more authors in the same order) with the same publication date are arranged alphabetically by title (excluding A or The).

Exception: If the references with the same authors published in the same year are iden- tified as articles in a series (e.g., Part 1 and Part 2), order the references in the series order, not alphabetically by title.

Place lowercase letters—a, b, c, and so forth—immediately after the year, withitC the parentheses:

Order of several works by different first authors with the same surname. Arrange worksby different authors with the same surname alphabetically by first initial:

Mathur, A. L., & Wallston, U. (1999). Mathur, S. E., & Ahiers, A. J. (1998).

Note: Include initials with the surname of the first author in text citations (see sec-tion 6.14).

Order of works with group authors or with no authors. Occasionally, a work will haveas its author an agency, association, or institution, or it will have no author at all.Alphabetize group authors, such as associations or government agencies, by thefirst significant word of the name. Full official names should be used (e.g., AmericanPsychological Association, not APA). A parent body precedes a subdivision (e.g.,University of Michigan, Department of Psychology).

If, and only if, the work is signed "Anonymous," begin the entry with the wordAnonymous spelled out, and alphabetize the entry as if Anonymous were a true name.If there is no author, move the title to the author position, and alphabetize theentry by the first significant word of the title. Treat legal references like references with no author; that is, alphabetize legal ref-erences by the first significant item in the entry (word or abbreviation). SeeAppendix 7.1 for the format of references for legal materials and ways to cite themin the text.

6.26 References Included in a Meta-Analysis If the number of articles contributing studies to the meta-analysis is relatively small(e.g., about 50 or fewer), they should appear in the reference list with an asteriskincluded to identify them. If the number of articles in the meta-analysis exceeds SO,then the references to the articles should be placed in a list and submitted as an onlinesupplemental archive. In this second case, if an article is mentioned in the text and isincluded in the meta-analysis, it should be cited both in the reference list and in thesupplemental materials.

Add the following statement before the first reference entry: References markedwith an asterisk indicate studies included in the mete-analysis. The in-text citations tostudies selected for meta-analysis are not preceded by asterisks. Bancjura A. U. (1977). Social learning theory. Englewood Cliffs, NJ: Prentice Hall.*Bretschneider J.

Reference Components In general, a reference should contain the author name, date of publication, title ofthe work, and publication data. The following sections (6.27—6.31) describe theseComponents Detailed notes on style accompany the description of each element, andexample numbers given in parentheses correspond to examples in Chapter 7 in sec-tions 7.1—7.11.

r REFERENCE COMPONENTS

6.27 Author and Editor Information Authors. • Invert all authors' names; give surnames and initials for up to and including seven

authors (e.g., Author, A. A., Author, B. B., & Author, C. C.). When authors number eight or more, include the first six authors' names, then insert three ellipses, and add the last author's name (see Chapter 7, Example 2). In text, follow the citation guide- lines in section 6.12.

• If the reference list includes different authors with the same surname and first initial, the authors' full first names may be given in brackets:

Janet, P. [Paul]. (1876). La notion de Ia personnalité [The notion of personality]. Revue Scientifique, 10, 574—575.

Janet P [Pierrel. (1906). The pathogenesis of some impulsions. Journal of Abnormal Psychology, 1, 1—17.

In text: (Paul Janet, 1876) (Pierre Janet, 1906)

• If an author's first name is hyphenated, retain the hyphen and include a period after each initial (Lamour, J.-B., for Jean-Baptiste Lamour).

• Use commas to separate authors, to separate surnames and initials, and to separate initials and suffixes (e.g., Jr. and Ill; see Chapter 7, Example 24); with two to seven authors, use an ampersand (&) before the last author.

• Spell out the full name of a group author (e.g., Royal Institute of Technology; National Institute of Mental Health; see Chapter 7, Examples 31, 32, 35, 68). In a reference to a work with a group author (e.g., study group, government agency, association, cor- poration), a period follows the author element.

• If authors are listed with the word with, include them in the reference in parenthe- ses: Bulatao, E. (with Winford, C. A.). The text citation, however, refers to the pri- mary author only.

• In a reference to a work with no author, move the title to the author position, before the date of publication (see Chapter 7, Examples 9, 30, 71). A period follows the title.

Editors. • In a reference to an edited book, place the editors' names in the author position, and

enclose the abbreviation Ed. or Eds. in parentheses after the last editor's name. period follows the parenthetical abbreviation (Eds.).

• In a reference to a chapter in an edited book, invert the chapter authors' names ad noted above but do not invert book editors' names.

• The name of the book editor should be preceded by the word In. Provide initials surnames for all editors (for substantial reference works with a large editorial naming the lead editor followed by et al. is acceptable).

If the date is given as a season, give theyear and the season, separated by a comma and enclosed in parentheses. • For papers and posters presented at meetings, give the year and month of the meet-ing, separated by a comma and enclosed in parentheses. • Write in press in parentheses for articles that have been accepted for publication butthat have not yet been published (see Chapter 7, Example 6). Do not give a date untilthe article has actually been published. (To reference a paper that is still in progress,under review, or being revised, see Chapter 7, Example 59.) • If no date is available, write nd. in parentheses. • For several volumes in a multivolume work or several letters from the same collec-tion, express the date as a range of years from earliest to latest (see Chapter 7,Examples 23 and 65). • For archival sources, indicate an estimated date that is reasonably certain but notstated on the document by using Ca. (circa) and enclose the information in squarebrackets (see Chapter 7, Example 67). • Finish the element with a period after the closing parenthesis.

• If the publisher is a university and the name of the state or province is included in the name of the university, do not repeat the name in the publisher location.

• The names of U.S. states and territories are abbreviated in the reference list and in the Method section (suppliers' locations); use the official two-letter U.S. Postal Service abbreviations. To cite locations outside the United States, spell out the city and the country names. However, if you are publishing outside the United States or for an international readership, check your institution's or publisher's specific style guidelines for writing out or abbreviating state, province, territory, and country names.

• Use a colon after the location. • Give the name of the publisher in as brief a form as is intelligible. Write out the

names of associations, corporations, and university presses, but omit superfluous terms, such as Publishers, Co., and Inc., which are not required to identify the pub- lisher. Retain the words Books and Press.

• If two or more publisher locations are given in the book, give the location listed first or, if specified, the location of the publisher's home office.

• When the author is also the publisher, use Author to indicate the publisher. Finish the element with a period.

6.31 Electronic Sources and Locator Information Since this manual was last updated, electronic journal publishing has gone from being the exception to the rule Publishing in the online environment has greatly increased the efficiency of publication processes and has contributed to a more vibrant and timely sharing of research results However, the electronic dissemination of information has also led to a number of new publishing models. Unedited articles can now be dissem- mated on the Internet in advance of publication. Links to supplementary material such as long data sets and videos can be embedded in electronic articles and made accessi- ble with a simple click. Corrections that were formerly noted in a subsequent journal

I. issue can now be made with no fanfare as a simple update to online files. All of these circumstances have called for new ways of tracking digital information.

In this new environment, some former models for referencing material no longer apply. It is not always clear how to distinguish the advance online version of an arti- cle from the final published version or how to determine which is the "version of record" (see section 6.24). Moreover, readers may be consulting the electronic version with supplemental material or the print version of the same article without supplemen- tal material. In the ephemeral world of the web, article links are not always robust.

In general, we recommend that you include the same elements, in the same order, as you would for a reference to a fixed-media source and add as much electronic retrieval information as needed for others to locate the sources you cited. We discuss

some key elements of the electronic retrieval process, beginning with some general information about uniform resource locators (URLs) and digital object identifiers

(DOTs) and ending with formatting guidance for citing publication data from electron-

ic sources.

Understanding a URL. The URL is used to map digital information on the Internet. The

components of a URL are as follows:

Protocol Host name Path to document Ill File name of specific

document

Protocol indicates what method a web browser (or other type of Internet software)

should use to exchange data with the file server on which the desired document resides.

The protocols recognized by most browsers are hypertext transfer protocol (HTTP),

hypertext transfer protocol secure (HTTPS), and file transfer protocol (FTP). In a

URL, the protocol is followed by a colon and two forward slashes (e.g., http:/I).

Host or domain name identifies the server on which the files reside. On the web,

it is often the address for an organization's home page (e.g., http://www.apa.org is the

address for APA's home page). Although many domain names start with "www," not

all do (e.g., http://journals.apa.org is the home page for APA's electronic journals, and

http://members.apa.org is the entry page to the members-only portion of the APA site).

The domain name is not case sensitive; for consistency and ease of reading, always type

it in lowercase letters. The domain name extension (in the preceding example, ".org") can

help you deter-

mine the appropriateness of the source for your purpose. Different extensions are used

depending on what entity hosts the site. For example, the extensions ".edu" and ".org"

are for educational institutions and nonprofit organizations, respectively; ".gov" and

mil" are used for government and military sites, respectively, and" com" and " biz"

are used for commercial sites Domain name extensions may also include a country

code (e g, " ca" for Canada or " nz" for New Zealand) The rest of the address mdi

cates the directory path leading to the desired document. All content on the Internet is prone to being moved, restructured, or deleted,

resulting in broken hyperlinks and nonworking URLs in the reference list. In an

attempt to resolve this problem, scholarly publishers have begun assigning a DO! to

journal articles and other documents.

The DOl system. Developed by a group of international publishers, the DOl

provides a means of persistent identification for managing information on digital net

works (see http://www.doi.org/). The DOI System is implemented through registratioiij

agencies such as CrossRef, which provides citation-linking services for the

publishing sector. According to their mission statement, CrossRef is dedicated

enable easy identification and use of trustworthy electronic content by promotiiC

the cooperative development and application of a sustainable (http://www.crossref.Orgfl.

CrossRef's participants have developed a system that provides two critical

tions. First, they assign each article a "unique identifier and underlying routing

tem" that functions as a clearinghouse to direct readers to content, regardless of whefl

the content resides (Kasdorf, 2003, p. 646). Second, they collaborate to use the DOl as an underlying linking mechanism "embedded" in the reference lists of electronic articles that allows click-through access to each reference. CrossRef currently has more than 2,600 participating publishers and scholarly societies.

The 001 as anicle identifiet A DOl is a unique alphanumeric string assigned by a registration agency (the International DOT Foundation) to identify content and provide a persistent link to its location on the Tnternet.

The publisher assigns a DO! when your article is published and made available electronically. All DOT numbers begin with a 10 and contain a prefix and a suffix sep- arated by a slash. The prefix is a unique number of four or more digits assigned to organizations; the suffix is assigned by the publisher and was designed to be flexible with publisher identification standards. We recommend that when DOIs are available, you include them for both print and electronic sources.

The DO! is typically located on the first page of the electronic journal article, near the copyright notice (see Figure 6.2). The DO! can also be found on the database land- ing page for the article (see Figure 6.3).

The linking function of DOls. The DOIs in the reference list function as links to the content you are referencing. The DO! may be hidden under a button labeled Article, CrossRef, PubMed, or another full-text vendor name (see Figure 6.4). Readers can then click on the button to view the actual article or to view an abstract and an oppor- tunity to purchase a copy of the item. Tf the link is not live or if the DOT is referenced in a print publication, the reader can simply enter the DOI into the DOI resolver search field provided by the registration agency CrossRef.org and be directed to the article or a link to purchase it (see Figure 6.5). Locating the article online with the DOT will give you electronic access to any online supplemental archives associated with the article (see section 2.13 regarding supplemental materials).

6.32 Providing Publication Data for Electronic Sources • For electronic versions based on a print source (as in PDF), give inclusive page num-

bers for the article cited. Use pp. before the page numbers in references to newspa- pers. See Chapter 7, Examples 1—3.

• Do not insert a hyphen if you need to break a URL across lines; instead, break the URL before most punctuation (an exception would be http://). Do not add a period after the URL, to prevent the impression that the period is part of the URL. This is not a style issue but a retrieval issue.

• Test URLs in your references at each stage prior to the submission and/or publica- tion of your work. If the document you are citing has moved, update the URL so that it points to the correct location. If the content is no longer available, substitute another source (i.e., the final version if you originally cited a draft) or drop it from the paper altogether.

• In general, it is not necessary to include database information. Journal coverage in a particular database may change over time; also, if using an aggregator such as EBSCO, OVID, or ProQuest (each of which contain many discipline-specific data- bases, such as PsycINFO), it may be unclear exactly which database provided the full text of an article.

• Some archival documents (e g , discontinued journals, monographs, dissertations, or papers not formally published) can only be found in electronic databases such as ERIC or JSTOR When the document is not easily located through its primary pub- lishing channels, give the home or entry page URL for the online archive.

• Do not include retrieval dates unless the source material may change over time (e.g., Wikis).

a As with references to material in print or other fixed media, it is preferable to cite the final version (i.e., archival copy or version of record; see section 6.24).

Reference Examples

This chapter contains examples of references in APA Style. The examples aregrouped into the following categories: periodicals; books, reference books, andbook chapters; technical and research reports; meetings and symposia; doctoral dissertations and master's theses; reviews and peer commentary; audiovisual media; data sets, software, measurement instruments, and apparatus; unpublished and informally pub- lished works; archival documents and collections; and retrievable personal communica- tions. In most categories, references to electronic or downloadable versions of each source type are integrated among references to print or other fixed media versions.

The most common kinds of references are illustrated here. Occasionally, however, you may need to use a reference for a source for which this chapter does not provide specific guidance. In such a case, choose the example that is most like your source and follow that format. Additional reference examples may be found on the APA Style website (www.apastyle.org). When in doubt, provide more information rather than less. Because one purpose of listing references is to enable readers to retrieve and usethe sources, most entries contain the following elements: author, year of publication, title, and publishing or retrieval data—all the information necessary for unique identi- fication and library search.

Following is an index to the reference examples that lists types of work referenced and variations of each reference element. The numbers after each index entry refer tothe numbered reference examples. Appendix 7.1 at the end of this chapter includes templates and example references to legal materials.

• This general format may be modified for collections requiring more or less specific information to locate materials, for different types of collections, or for additional descriptive information (e.g., a translation of a letter). Authors may choose to list correspondence from their own personal collections, but correspondence from other private collections should be listed only with the permission of the collector.

• As with any reference, the purpose is to direct the reader to the source, despite the fact that only a single copy of the document may be available and the reader may have some difficulty actually seeing a copy.

REFERENCE

• Include as much information as is needed to help locate the item with reasonable ease within the repository. For items from collections with detailed finding aids, the name of the collection may be sufficient; for items from collections without finding aids, more information (e.g., call number, box number, file name or number) may be necessary to help locate the item.

• If several letters are cited from the same collection, list the collection as a reference and provide specific identifying information (author, recipient, and date) for each letter in the in-text citations.

• Use square brackets to indicate information that does not appear on the document. Use question marks to indicate uncertainty regarding names and dates; use ca. (circa, not italicized) to indicate estimated dates (see Example 67).

• For interviews and oral histories, list the interviewee as the author. Include the inter- viewer's name in the description.

• If a publication of limited circulation is available in libraries, the reference may be formatted as usual for published material, without the archival source.

APPENDIX 7.1: REFERENCES TO LEGAL MATERIALS

Appendix 7.1: References to Legal Materials Legal periodicals and APA journals differ in the placement and format of references. The main difference is that legal periodicals cite references in footnotes, whereas APA journals locate all references, including references to legal materials, in the reference list. For most references, use APA format as described in this chapter. References to legal materials, however, which include court decisions, statutes, other legislative materials, and various secondary sources, are more useful to the reader if they provide the information in the conventional format of legal citations. Some examples of refer. ences and citations to court cases, statutes, and other legislative materials appear in this appendix along with guidelines for their preparation. For more information on preparing these and other kinds of legal references, consult the latest edition of The Bluebook: A Uniform System of Citation (Bluebook; 18th ed., 2005), which is the source for the legal citation style that follows.

Ensure that your legal references are accurate and contain all of the information necessary to enable a reader to locate the material being referenced. Consult law librar- ians to verify that your legal references (a) contain the information necessary for retrieval and (b) reflect the current status of the legal authority cited to avoid the pos- sibility of relying on a case that has been overturned on appeal or on legislation that has been significantly amended or repealed.

A7.O1 General Forms A reference form is provided in each of the following sections. For the most part, each reference form for statutes and other legislation includes (a) a popular or formal title or name of the legislation and (b) the citation, either to the published compilation of legislative materials where the legislation is codified (e.g., a specific numbered section of a specific volume of the United States Code), including the statutory compilation's publication date in parentheses, or the identifying label for the legislation assigned by the enacting body during the particular legislative session (e.g., a specific section of an act identified by its public law number).

A typical reference form for court decisions includes (a) the title or name of the case (usually one party vs. another); (b) the citation, usually to a volume and page of one of the various sets of books (called reporters, which usually contain decisions of courts in particular political divisions, or jurisdictions) where published cases can be found (e.g., the Federal Reporter, Second Series); and finally, (c) the precise jurisdiction of the court writing the decision (e.g., the New York Court of Appeals), in parenthe- ses, including the date of the decision.

For both legislation and court decisions, the citation may be followed by certain additional descriptive information that pertains to the content of the legislation or court decision, the history of the legislation or court decision (e.g., later appeals of court decisions or later amendments to legislation), or other sources from which the legislation or court citation may be retrieved. Authors are encouraged to consult the Bluebook for the proper format for such additional information. Follow the Bluebook closely for correct abbreviation style. Some examples of the more common abbrevia- tions that appear in APA journals are shown here.

A7.02 Text Citations of Legal Materials Although the reference format for legal materials differs from that of other kinds ofworks cited in APA publications, the text citations are formed in the same way andserve the same purpose. As for works with no identified author (see section 6.15), givethe first few words of the reference list entry and date; that is, give enough informa-tion in the text citation to enable the reader to locate the entry in the reference listquickly and easily. Examples of text citations and reference entries for specific kinds oflegal materials are given in the following sections.

A7.03 Court Decisions (Bluebook Rule 10) In text, cite the name of the case (italicized) and the year of the decision. If two or moreyears are given, cite those years as well. Court cases often have several years, each ofwhich reflects a specific stage in the case's history. Giving only one date could give theimpression that only a single point in the case's history is being cited or might misleada reader as to the timing of the case.

Reference form for cases:

Name v. Name, Volume Source Page (Court Date).

Abbreviate the published source (if any), court, and date as specified in the Bluebook. I. Sample reference list entry to a case

Text citation:

Dudlinger v. Art//es (1981/1984)

Explanation: This decision was rendered by the federal district court for the District of Kansas in 1981. On appeal, the decision was affirmed by the 10th Circuit Court of Appeals in 1984. Consult the Bluebook for the proper forms to signal the various stages in a case's history.

Unpublished cases:

3. Sample reference to an unreported decision

Gilliard v. Oswald, No. 76-2109 (2d Cir. March 16, 1977).

Explanation: The docket number and the court are provided. The opinion was announced on March 16, 1977. To cite to a particular page of a slip opinion (opinion that is not published in a case reporter but is separately printed), use the form slip op. at [page number].

Alternative: You may cite unreported cases found on electronic databases, such as LEXIS or Westlaw, instead of citing them to slip opinions. Give the name of the data- base, a record number if available, and enough information for the reader to find the case. Precede screen page numbers, if assigned, with an asterisk to distinguish them from the page number of the slip opinion; paragraph numbers, if assigned, should be preceded by a paragraph symbol.

With record number:

are called superior courts or supreme courts, which can be confusing because one usu-ally thinks of the supreme court as the highest court in any particular jurisdiction andnot as the lowest. Authors should check the Bluebook for a listing of each jurisdiction'sparticular court structure.) The decision can be located in Pennsylvania District andCounty Reports, Fourth Series, beginning on page 168 of that volume. 5. Sample reference to a federal district court opinion

v. Monsanto Co., 627 F. Supp. 418 (S.D. W.Va. 1986).

11. Sample reference to a statute in a federal code

Americans With Disabilities Act of 1990, 42 U.S.C.A. § 12101 at seq. (West

1993).

Explanation This act can be located beginning at section 12101 of title 42 of the United States Code Annotated, which is the unofficial version of the United States Code (the official statutory compilation of the laws enacted by Congress). Et seq. is a

Latin phrase meaning "and following" and is a shorthand way of showing that the act

covers not just the initial section cited but also others that follow the initial section The text in parentheses indicates that the United States Code Annotated is published

by West Publishing and that 1993 is the publication date of the volume in which the cited sections can be found Citing to U S C, U S C A, or U S C S is the preferred

method of citing legislation, because codified legislation is usually easier to work with

and retrieve than is a session law, the form of legislation before it is codified. A session

law citation is constructed as follows:

Americans With Disabilities Act of 1990, Pub. L. No. 101-336, § 2, 104 Stat. 328

(1991).

REFERENCE EXAMPLES

Explanation: The citation is to the version of the act in its uncodified form. The act was the 336th public law enacted by the lOlst Congress. Section 2 is the particular section of the act cited 2 happens to correspond to § 12101 of 42 U.S.C.A., which is where § 2 was ultimately codified). The text of the section cited can also be found in the official compilation of uncodified session laws, called United States Statutes at Large (abbreviated Stat.) at volume 104, p. 328.

The Publication Process

T he author, editor, and publisher share responsibility for the ethical and efficient handling of a manuscript. This responsibility begins when the editor receives the manuscript and extends through the life of the published article. In this chapter,

we describe the peer review process, focusing first on how editors evaluate manuscripts. Next, we delineate the author's responsibilities in four areas: (a) preparing the manuscript for submission, (b) attending to administrative and ethical responsibilities, (c) complying with publisher policy requirements, and (d) working with the publisher during the pro- duction process.1

Editorial Process 8.01 Peer Review Scholarly journal articles are original, primary publications. This means that they have not been previously published, that they contribute to the archive of scientific knowl. edge, and that they have been reviewed by a panel of peers. The peer-reviewed litera- ture in a field is built by individual contributions that together represent the accumu- lated knowledge of a field.

To ensure the quality of each contribution—that the work is original, valid, and significant—scholars in the subspecialties of a field carefully review submitted man- uscripts. By submitting a manuscript to a peer-reviewed journal, an author implicitly consents to the circulation and discussion of the manuscript. During the review process, the manuscript is considered a confidential and privileged document, but publishers differ, so check the journal's instructions to authors (see section 1.14, for

'This chapter gives instructions to authors of journal articles. Authors and editors of book manuscripts should follow instructions given by the publisher's book production department. For information on dissertations and master's theses, see 'Converting the Thesis or Dissertation into an Article" on the APA Style website (www.apastyle.org).

EDITORIAL PROCESS

a discussion of the ethical standards that have been established for manuscript reviewers).

The editor of each journal is responsible for the quality and content of the journal. Journal editors look for manuscripts that (a) contribute significantly to the content area covered by the journal, (b) communicate with clarity and conciseness, and (c) fol- low style guidelines. Journal editors are often assisted by associate editors, who assume responsibility for a specific content area of the journal or for a portion of the manu- scripts submitted to the journal. For some journals, an associate editor may act as edi- tor at all stages of the consideration of a manuscript (i.e., as an action editor), includ- ing communication with an author regarding acceptance, rejection, or required revi- sion of a manuscript. Consulting and advisory editors and ad hoc reviewers review manuscripts and make recommendations to editors or to associate editors concerning the disposition of manuscripts. However, the editor has the final editorial authority and may make a decision other than that recommended by the reviewers.

The editor may accept or reject a manuscript outright, that is, before its review by an associate editor or by reviewers. More typically, however, the editor sends the man- uscript to an associate editor or directly to reviewers.

Reviewers. An action editor usually seeks the assistance of several scholars in the con- tent area of the submitted manuscript in arriving at an editorial decision. An action editor may solicit reviews from particular scholars for any number of reasons, includ- ing technical expertise, familiarity with a particular controversy, and balance of per- spectives. Reviewers provide scholarly input into the editorial decision, but the deci- sion is the action editor's alone to make.

Masked review. Journal editors, either routinely or at the author's request, may use masked review. In masked review, the identity of the author of a manuscript is con- cealed from reviewers during the review process. Consult the instructions to authors in the journals to which you submit your manuscripts to determine whether a journal routinely uses masked review or offers masked review to authors who request it. Authors are responsible for concealing their identities in manuscripts that are to receive masked review; for example, they should take extra care to format their man- uscripts so their identities as document creators are not easily revealed. It is APA pol- icy that authors' names will not be revealed to reviewers after the review process is complete without the consent of the authors. Further, the APA review process is masked in both directions; reviewer identities will not be revealed to authors unless the reviewer chooses to do so.

liming of peer review. The period of review can vary, depending on both the length and complexity of the manuscript and the number of reviewers asked to evaluate it, but the review process typically takes approximately two to three months. After that time, the author can expect to be notified as to the status of the manuscript. It would be appro- priate for an author to contact the editor if no communication has been received after more than three months.

8.02 Manuscript Acceptance or Rejection Reviewers provide the editor with evaluations of a manuscript on the basis of their assessment of the scholarly quality of the manuscript, the importance of the novel con-

THE PUBLICATION PROCESS

tribution that the work might provide, and the appropriateness of the work to the par- ticular journal. The decision to accept a manuscript, to reject it, or to invite a revision is the responsibility of the editor; the editor's decision may differ from the recommen- dation of any or all of the reviewers. Editors may generally choose one of three actions:

1. Acceptance. Once a manuscript is accepted, it enters into the production phase of publication. No further changes may be made by the author to the manuscript other than those recommended by the copyeditor. The author remains responsible for the completion of all associated paperwork (e.g., copyright transfers, disclosures, per- missions). Failure to complete all required paperwork may result in retraction of the acceptance of a manuscript.

2. Rejection. A manuscript is usually rejected because (a) the work is seen as falling outside the coverage domain of the journal; (b) it contains such severe flaws of design, methodology, analysis, or interpretations that the editor questions the valid- ity of the submission; or (c) it is judged as making a limited novel contribution to the field. At times, editors reject good manuscripts simply because they lack the space to publish all of the high-quality manuscripts that are submitted to the jour- nal. A manuscript that has been rejected by a journal may not be revised and resub- mitted to that same journal.

If a manuscript is rejected and the author believes a pertinent point was over- looked or misunderstood by the reviewers, the author may appeal the editor's deci- sion by contacting the editor. Those who feel their manuscripts are unfairly rejected by APA journals may appeal such decisions to the Chief Editorial Advisor.

3. Rejection with invitation to revise and resubmit. This category applies to a range of manuscripts that are judged to have a high potential for eventual publication in the journal but that are not yet ready for final acceptance. Manuscripts in this catego- ry range from those that the editor has judged to need substantial reworking (includ- ing the possibility that additional empirical data may need to be gathered, that entirely new experiments may need to be added, or that analyses need to be modi- fied) to those that need only a small number of specific modifications. Some jour- nals use a category labeled conditional acceptance for this latter level of revision. Rejection with invitation to revise and resubmit does not guarantee eventual publi- cation of the paper by that journal. In many cases, this invitation is time bound; it does not extend across changes in editors.

Most manuscripts need to be revised, and some manuscripts need to be revised more than once (revision does not guarantee acceptance). Initial revisions of a man- uscript may reveal to the author or to the editor and reviewers deficiencies that were not apparent in the original manuscript, and the editor may request further revision to correct those deficiencies. During the review process, an editor may ask an author to supply material that supplements the manuscript (e.g., complex statistical tables, instructions to participants). As the manuscript moves through the review process, editors are free to solicit reviews from reviewers who were not among the initial set of reviewers.

If the editor rejects a manuscript or returns it to the author for revision, the editor explains why the manuscript is rejected or why the revisions are required.

AUTHOR RESPONSIBILITIES

The editor does not have to provide the reviewers' comments to the author but frequently chooses to do so. Editors do not undertake major editorial revision of manuscripts. Authors are expected to attend to editors' detailed recommendations for revision; however, the content and style of the article remain the sole respon- sibility of the author. Slavish compliance with all recommendations of all review- ers may result in a manuscript that is difficult to comprehend, which is not the intent of the review process. When resubmitting a revised manuscript, authors are encouraged to enclose a cover letter explaining how they have responded to all the reviewers' comments (regardless of whether the authors agreed or disagreed with the comments).

Author Responsibilities 8.03 Preparing the Manuscript for Submission The specific requirements for submitting a manuscript differ among journals. Therefore, before submitting a manuscript, refer to the journal's website. The journal's instructions to authors will tell you (a) the journal's area of coverage, that is, what kinds of manuscripts are appropriate for that journal; (b) the current editor's name and address; and (c) instructions for manuscript preparation and submission specific to that journal, including whether the journal routinely uses masked review.

Uuality of presentation. The physical appearance of a manuscript can enhance or detract from it. A well-prepared manuscript encourages editors and reviewers to view your work as professional. In contrast, mechanical flaws sometimes lead reviewers to misinterpret content.

In this section, we describe the mechanical details of producing a manuscript that meets requirements for peer review and publication in a scholarly journal. Publishers will produce the typeset version of your article directly from your word-processing file, should your manuscript be accepted for publication. The instructions given in this chapter lay the groundwork for producing a usable electronic file.

Assistance in scientific writing in English. Scholars who are not experienced in scien- tific writing in English can be hindered in their publishing efforts by a lack of familiar- ity with idiomatic language usage. These individuals are urged to correct the problem by consulting with colleagues who are experienced writers in the English language. They may also wish to contact copyediting services that can help authors evaluate and correct their manuscripts. We highly recommend use of these services for those who consistently face obstacles in getting their work published.

Format. Formatting your manuscript according to the specifications described in this section enhances clarity and readability and facilitates peer reviews, copyediting, and typesetting.

Typeface. The use of a uniform typeface and font size enhances readability for the editor and allows the publisher to estimate the article length. The preferred typeface for APA publications is Times New Roman, with 12-point font size.

A seriftypeface, "with short light lines projecting from the top or bottom of a main stroke of a letter" (Chicago Manual of Style, 2003, p. 837), is preferred for text

r

THE PUBLICATION PROCESS

because it improves readability and reduces eye fatigue. (A sans serif type may be used in figures, however, to provide a clean and simple line that enhances the visual presen- tation.) Do not use a compressed typeface or any settings in your word-processing soft- ware that decrease the spacing between letters or words. The default settings are nof- mally acceptable.

Special characters. Special characters are accented letters and other diacriticals, Greek letters, math signs, and symbols. Type all special characters that you can, using the special character functions of your word-processing program.

Line spacing. Double-space between all text lines of the manuscript. Double-space after every line in the title, headings, footnotes, quotations, references, and figure cap- tions. Although you may apply triple- or quadruple-spacing in special circumstances, such as immediately before and after a displayed equation, never use single-spacing or one-and-a-half spacing except in tables or figures.

Margins. Leave uniform margins of at least 1 in. (2.54 cm) at the top, bottom, left, and right of every page. Combined with a uniform typeface and font size, uniform margins enhance readability and provide a consistent gauge for estimating article length.

Line length and alignment The length of each typed line is a maximum of 6½ in. (16.51 cm). Do not justify lines; that is, do not use the word-processing feature that adjusts spacing between words to make all lines the same length (flush with the mar- gins). Instead, use the flush-left style, and leave the right margin uneven, or ragged. Do not divide words at the end of a line, and do not use the hyphenation function to break words at the ends of lines. Let a line run short rather than break a word at the end of a line.

Paragraphs and indentation. Indent the first line of every paragraph and the first line of every footnote. For consistency, use the tab key, which should be set at five to seven spaces, or ½ in. The default settings in most word-processing programs are acceptable. Type the remaining lines of the manuscript to a uniform left-hand margin. The only exceptions to these requirements are (a) the abstract, (b) block quotations, (c) titles and headings, (d) table titles and notes, and (e) figure captions.

Order of manuscript pages. Arrange the pages of the manuscript as follows:

• title page

The title page includes five elements: title, running head, author byline, institution- al affiliation, and author note. Identify the title page with the page number 1. The remaining pages should be numbered consecutively, using Arabic numerals (except for artwork and figures).

The running head is an abbreviated title that is printed at the top of the pages of a manuscript or published article to identify the article for readers. The running head should be a maximum of 50 characters, counting letters, punctuation, and spaces between words. It should appear flush left in all uppercase letters at the top of the title page and all subsequent pages.

• abstract (start on separate page, numbered page 2) • text (start on a separate page, numbered page 3)

AUTHOR RESPONSIBILITIES

• references (start on a separate page) • tables (start each on a separate page) • figures (start each on a separate page; include caption on page with figure) • appendices (start each on a separate page)

Page numbers and manuscript page headers. After the manuscript pages are arranged in the correct order, number them consecutively, beginning with the title page. Pages occasionally are separated during the editorial process, so identify each manuscript page with the running head along with the page number. (Do not use your name to identify each page, because the name will have to be removed if the manuscript receives masked review.)

Use the automatic functions of your word-processing program to generate headers and page numbers for your file. (Do not type these manuscript page headers repeatedly in your word-processing file.)

Spelling check. Most word-processing programs have a function that checks spelling. Use it. Although an electronic spelling check cannot take the place of proofreading the article, because words spelled correctly may be used incorrectly, it will lessen the chance that typographical errors in the manuscript will make their way into print when your electronic file is used to publish the article.

Supplemental materials. If you are submitting supplemental materials with your man- uscript (see section 2.13), check the journal's website to determine the preferred for- mat. If you are submitting your manuscript to an APA journal, you will need to

• submit a separate file for each supplemental document and specify the format, nam- ing your files consistently and including the file format in the naming convention;

• provide a title for each document, bearing in mind that the file will be viewed sepa- rately from the article and will need to be sufficiently identified to be useful for the reader;

• include a context statement for each file that specifies precisely what the document or file is intended to communicate (readers should be able to ascertain what they will find in the file from the statement, whether it contains several sentences or just a few); and

• prepare each document so it is complete—that is, tables and figures intended for sup- plemental material should include captions in the document just as if they were appearing in the published article.

Obtain and submit necessary permission to reproduce images (in addition to copy- righted material, keep in mind that images of human subjects require the subjects' per- mission; see http://www.apa.org/journals for more guidance on supplemental material).

Cover letter. Check the journal's website for the current editor's name and for specific instructions on submission. When submitting a manuscript for consideration, enclose a letter that includes the following elements:

• specific details about the manuscript (title, length, number of tables and figures); • a request for masked review, if that is an option for the journal and you choose to

use it;

• recommendations for potential reviewers or reviewers to avoid (optional); • information about any previous presentation of the data (e.g., at a scientific meeting);

THE PUBLICATION PROCESS

• jnformation about the existence of any closely related manuscripts that have been submitted for simultaneous consideration to the same or to another journal;

• notice of any interests or activities that might be seen as influencing the research (e.g., financial interests in a test or procedure, funding by pharmaceutical companies for drug research);

• verification that the treatment of subjects (human or animal) was in accordance with established ethical standards; and

• a copy of the permission granted to reproduce or adapt any copyrighted material from another source or a notice that permissions are pending. (The publisher will need copies of all granted permissions on receipt of your accepted manuscript.)

The corresponding author is responsible for ensuring that all authors are in agree- ment with the content of the manuscript and with the order of authorship before sub- mitting an original or revised submission (see section 1.13). The cover letter should assure the editor that such agreements have been reached and that the corresponding author will take responsibility for informing coauthors in a timely manner of editorial decisions, reviews received, changes made in response to editorial review, and the con- tent of revisions. If the manuscript is accepted, all the authors will need to certify authorship.

Finally, include your telephone number, fax number, e-mail address, and mailing address for future correspondence. (See Figure 8.1 for a sample cover letter.)

Interim correspondence. While a manuscript is under consideration, be sure to inform the editor of any substantive corrections needed, any change in address, and so forth. In all correspondence, include the complete manuscript title, the authors' names, and the man- uscript number (which is assigned by the editor when the manuscript is first received).

8.04 Complying With Ethical, Legal, and Policy Requirements In Chapter 1, we noted that authors are responsible for demonstrating that they have complied with the ethical standards that govern scholarly publishing. When you sub- mit a manuscript to a journal editor for consideration, you may be asked to provide proof of compliance with these standards. You are also expected to comply with legal standards of fair use when reprinting or adapting the work of others and to comply with the publication policies established by the journal publisher.

Ethical conduct of research and conflicts of interest. When you submit your manuscript, you may be asked to verify that you have complied with ethical standards in the con- duct of your research. You may also be asked to disclose potential conflicts of interest and to indicate financial agreements or affiliations with any product or services used or discussed in your papers well as any potential bias against another product or ser- vice. The forms used by APA for this purpose are provided in Figures 8.2 and 8.3.

Permission to reprint or adapt the work of others. If your paper includes material bor- rowed from another source, you must cite the original source in your paper (for more on including your own previously published work in a paper, see section 1.10 on self- plagiarism). It is the author's responsibility to (a) obtain letters of permission from copyright holders to reproduce copyrighted material and (b) enclose copies of these let- ters with the accepted manuscript.

Meredith S. Simpson, PhD Editor, Journal of Poetry and Psychology Department of Psychology University of Xanadu 9 Prentice Hall Xanadu, NY 10003-1212

Dear Dr. Simpson:

I am enclosing a submission to the Journal of Poetry and Psychology entitled, 'Poetry and the Cognitive Psychology of Metrical Constructs." The manuscript is 40 pages long and includes 4 tables and I figure. I wish for the manuscript to be given a masked review and request that it not be sent to my ex-husband [name blocked out] for review. Although he is an expert in the area, I do not helieve that he would be ahle to provide an unbiased review at this time.

Some of the data from this paper were previously presented at the annual meeting of the Poetry and Psychology Society in San Diego (May 2006). This is one of a series of papers examining cognition and creative writing (see references for a listing of those puhlished and in press). There is some overlap in the content of the introduction sections, which we have noted in the text. We would be happy to provide copies of the other manuscripts if there should be any concern about duplicate or fragmented publication. My coauthors and I do not have any interests that might be interpreted as influencing the research, and APA ethical standards were followed in the conduct of the snidy.

I have enclosed a copy of the permission granted us for the adaptation we made to the figure; permission is pending from the publisher for the poetry that is reproduced.

I. will be serving as the corresponding author for this manuscript. All of the authors listed in the byline have agreed to the byline order and to submission of the manuscript in this form. I have assumed responsibility for keeping my coauthors informed of our progress through the editorial review process; the content of the reviews, and any revisions made. I understand that, if accepted for publication, a certification of authorship form will be required that alt coauthors will sign.

Sincerely,

Janet Sestina, PhD, Associate Professor University of Melville 112 Oceanside Drive Qile4ueeg, ME 20031-2221 218-555-1212 (voice) 218-555-1213 (fax) [email protected]

The following are some examples of material that require permission:

• Figures and tables: Along with directly reprinted figures and tables, this also includes figures and tables that have been adapted from or are very similar to previously pub- lished figures and tables.

• Data: This applies only to data that are directly reproduced from another source; data that have been reconfigured or reanalyzed to produce different numbers do not require permission.

In psychology, as in other scientific disciplines, professional comaaunicationn sac presumed to be based on objecliveinletpreraeions ofevidence and unbiased inleapretalions offace. Asa author's economic and coanonerciat interests in products orservices used or discussed in their papers may color such objectivity. Although such relationships do not necessarily constitute

conflict of interest, the integrity of the field requites disclosure ofthe ponsibilities ofsuch potentially distotting influences where they may exist. The reader may then judge and, if necesnary. make allowance for tile impact of the bias on theinformation being reported.

In general, the safest and most open coarse of action is to disclose uctivities and relationships that, if known to others, might be viewed as a conflict of interest, even if you do not believe that any conflict or bias exists.

whether an interest is 'significant" will depend on individual circumstances and cannot be defined by a dollar amount.Holdings in s company through a mutual flund are not ordinarily sufficient to wat-rani disclosure, wheeeas salaaies, researchgrants, consulting fees, and pemonal stock holdings would be. Being thecopyright holder ofandtor recipient ofroyallim frompsychological lest might he another example. Panlicipation on a hoard ofdireclors or any otherrelationahip wilh an enlity or

person Ihat is in some way paul of the paper should also be carefitlly conaidered for possible disclosure.

tn addition to disclosure of possible soutces of positive bias, authota should alto curefitlty consider disclosure where circumslances could suggest bias against a product, nervice, facility, or person. For eaampte, having a copynight or royalty interest in a competing psychological test or assessment protocol night be seen as a possible source of negative bias againstmolher It-st instrument.

AUTHOR RESPONSIBILITIES

Permissions policies differ from publisher to publisher. Consult your publisher directly to determine the policies that apply. Requests for permission to reproduce material should be directed to the publisher's permissions office (see, e.g., http:// www.apa.org/about/copyright.html).

When permissions are required, you must request permission to reproduce the material in all formats. Some publishers may also require that you obtain permission from the author of the original work. Publishers normally grant permission contingent on the inclusion of a copyright notice on the first page of reproduced material and pay- ment of a fee per table, figure, or page.

Allow ample time (several weeks) to secure permission. At the time of submission, identify the copyright holder and request permission to reprint or adapt the material in both print and electronic form. Determining who holds the copyright can be a chal- lenge, particularly for older works, because publishers may merge and copyrights may change hands. The permissions request should specify the source material (title of work, year of publication, page number, etc.) and the nature of the reuse (e.g., reusing in a journal). (See Figure 8.4 for the APA form used to request permission.)

Permission can be secured via fax, mail, or e-mail. Many publishers have online submission forms for requesting permission that can be accessed from their websites (e.g., see http://www.apa.org/journals and click on Copyright and Permission Information to request permission to reproduce material published by APA). Most publishers will not allow your article to enter into production until all print and electronic permissions are secured for reproduced items and forwarded with your manuscript.

Once permission is granted, the author needs to include a permissions notice in the manuscript, following the wording and format shown in section 2.12 or the specific wording at the copyright holder's request.

8.05 Publisher Policy Requirements

Transfer of copyright. When a manuscript is accepted for publication, the journal edi- tor sends to the author a legal form regarding copyright and authorship. By transfer- ring copyright, authors permit publishers to (a) more widely distribute the work, (b) control reuse by others, and (c) handle the paperwork involved in copyright registra- tion and administration. The publisher in turn represents the author's interests and permits authors to reuse their work in several ways.

The corresponding author (a) transfers the copyright on the article to the publisher or (b) certifies that the majority of the authors or the primary authors are employees of the U.S. government and that the work was performed as part of their employment and is not protected by U.S. copyright law (therefore, it is in the public domain). In the case of work performed under U.S. government contract, the publisher may retain the copy- right but grant the U.S. government royalty-free permission to reproduce all or portions of the article and authorize others to do so for U.S. government purposes. By law, pub- lishers own the copyright on their journal articles for 95 years from the time of publi- cation. The copyright transfer includes both print and electronic rights to the article to allow the publisher to disseminate the work as broadly as possible.

Posting articles on the Internet. Certain rights are linked to copyright ownership, including the exclusive right to reproduce and distribute the copyrighted work. Journals are committed to publishing original scholarship and distributing peer-

Authors of articles pub- lished in APA journals may post a copy of their final manuscript (e.g., as a word- processing file) on a personal website or on the author's employer's server after it is accepted for publication. The following conditions prevail:

• The posted manuscript must carry an APA copyright notice and include a link to the APA journal home page (http://www.apa.org/journals).

• The posted manuscript must include the following statement: "This manuscript may not exactly replicate the final version published in the APA journal. It is not the copy of record."

a APA does not permit archiving with any other non-APA repositories. • APA does not provide electronic copies of the APA published version for this pur-

Complying with the National Institutes of Health (NIH) public access policy. The "Revised Policy on Enhancing Public Access to Archived Publications Resulting from NIH-Funded Research," notice number NOT-OD-08-033, took effect April 7, 2008.

Under this policy, NIH-funded investigators (or their publishers) are required to deposit to PubMed Central an electronic version of their final, peer-reviewed and accepted manuscript at acceptance to be made publicly available within 12 months of publishers' final publication date.

For detailed guidance about this policy, check with your publisher. If you are publish- ing in an APA journal, consult the APA Journals website (http://www.apa.org/journals).

8.06 Working With the Publisher When the Manuscript Has Been Accepted

After your manuscript has been accepted for publication, your publisher will contact you with detailed instructions on working with copyeditors, proofreading the typeset manuscript, and monitoring the production process.

Preparing the word-processing file for copyediting and typesetting. Most publishers request that authors provide the electronic word-processing files containing their manuscript, figures, and other materials to the production office for copyediting and production. You may be asked to provide the electronic manuscript files by e-mail or through a submission portal. Consult the instructions to authors for the journal to which you are submitting your paper for the latest guidance on manuscript file preparation.

Reviewing the proofs. Both journal editors and copyeditors introduce changes in man- uscripts to correct errors of form, to achieve consistency of style, or to clarify expres- sion. The corresponding author needs to review the edited manuscript carefully, being alert for changes in meaning and being attentive to levels of heading and to markup of statistics, equations, and tables. It is important to check the proofs word for word against the manuscript to catch typographical errors.

Limit changes on these proofs to corrections of production errors and to updates of reference citations or addresses. This is not the time to rewrite the text. Be sure to check the following:

• Are all queries fully answered? • Is the hierarchy of headings and subheadings correct?

AUTHOR RESPONSIBILITIES

• Are all numbers and symbols in text, tables, and mathematical and statistical copy correct?

• Are tables correct? Are table alignment notes, superscripts, and footnotes correct? • Are figures correct? Are captions and numbers correct? Are all labels properly

spelled? Do symbols in the legends match those in the figure? Are your photographs reproduced successfully?

If coauthors participate in the review of the copyedited manuscript, the correspon- ding author is responsible for consolidating necessary changes and forwarding them to the publisher. It is important to submit your requested changes to the publisher with- in the established deadline so publication of your article will not be delayed.

Retaining raw data. The tradition in scientific publishing is to retain data, instructions, coding systems, details of procedure, and analyses so that copies may be made avail- able in response to inquiries from interested readers (see section 1.08). APA, for exam- ple, expects you to retain these materials for a minimum of five years after your arti- cle has been published.

Initial observations may take many forms, including, for example, participant responses to individual test or survey items, videotapes of participant performances, interviewer or observer notes, and physiological recordings. They need to be retained in a form that to the extent possible ensures that the information available to the orig- inal researcher is also available to the researcher seeking to confirm the original find- ings. For example, retaining only an electronic data file containing scale scores derived from a questionnaire is insufficient. A scoring or coding system for the logging or transformation of data should also be retained. Choose an archival form for retaining data that ensures that no information is lost; do not simply opt for the most expedient means of archiving (e.g., using optical scanners to record response sheets may cause future problems; Sackett, 2000).

Correction notices. From time to time, errors occur in published journal articles. If you detect an error in your published article and think that a correction notice is warranted, submit a proposed correction notice to the journal editor. The notice should contain the following elements: (a) full journal title and year, volume number, issue number (when appropriate), and inclusive page numbers of the article being corrected; (b) com- plete article title and names of all authors, exactly as they appear in the published arti- cle; (c) precise location of the error (e.g., page, column, line); (d) exact quotation of the error or, in the case of lengthy errors or an error in a table or figure, an accurate paraphrasing of the error; and (e) concise, unambiguous wording of the correction. Because it is not the purpose of corrections to place blame for mistakes, correction notices do not identify the source of the error.

FOUNDATIONS OF MENTAL HEALTH COUNSELING 9

Foundations of Mental Health Counseling

1. Interview

I interviewed Glendora Dvine, a licensed professional counselor operating in her private practice Dvine Systems GA. Glendora is a successful female counselor who has been interacting with diverse clients for more than 8 years. Her contact details are found on her website at familycounselorinmcdonoughga.com.

Glendora noted that her responsibilities as a mental health counselor varied from promoting healthy lifestyles to the provision of group and individual therapy. Additionally, clinical assessments, diagnosis, and treatment are parts of her responsibilities. In general, the counselor argued that mental health counseling was an interdisciplinary and multifaceted profession which targeted the preservation and restoration of the client’s mental health. As a professional counselor, she felt the urge to identify an individual’s problems and develop techniques to alleviate the challenges at the personal level. She also works tirelessly to equip clients with effective tools for self –help- a phenomenon known as psycho-education (Leppma, 2012).

Though Glendora previously worked with multiple clients presenting a wide range of problems, she identified her ideal clients as young adults dealing with substance abuse, self-esteem issues, anxiety, and depression. In this case, the rise in the rates of suicide and incarceration among young adults of the minority groups motivated the interviewee’s choice of client. She also noted that group therapy worked perfectly with her clients as a result of effective leadership skills. Additionally, she argued that as a counselor, she had the moral duty to integrate theory, techniques, and ethics in solving the problems of the multicultural populations.

Glendora revealed that she was registered as a nationally certified counselor. Glendora also completed a CACREP approved program in mental health counseling. She also cited being a professional member of the American Counseling Association.

When it comes to training, the interviewee stated that this far, the theory of the behavioral sciences accounted for many training programs. In addition, she participated in several CACREP accredited programs some of which required 100 hours of face to face supervision. On the other hand, the AMHCA standards of clinical practice provided guidance in clinical assessments, diagnosis, and treatment (Hurt-Avila & Castillo, 2017). The ACA code of ethics also stipulated guidelines for an ethical practice.

Glendora suggested that the same techniques used to identify and remove stressors in clients were useful for the counselor’s self-care. In this case, she noted that counselors should be self-aware in order to externalize and contain their problems. For this reason, counselors should develop a consistent plan that allows them to engage in nourishing activities. They should also create emergency strategies for unprecedented stressors and seek support from peers and colleagues. Lastly, she noted that the most useful self-care tool is self-compassion.

The interviewee’s advice for counselors in training was to identify the passion and sources of motivation before selecting an area of specialization if they envisioned a rewarding career. In addition, she proposed that counselors in training should study the future direction of the counseling profession since it is on an ongoing development.

2. Benefits of ACA Membership

The ACA Government Relations listserv keeps members informed of any new legislation and the implications to the counseling profession (Yep, n.d). Also, by being a member of the ACA, one can access regular updates on relevant program and funding support. On the other hand, the ACA membership certificate serves as an important tool to show the credibility of counselors and leadership in adherence to the ACA code of ethics. Therefore, clients are likely to trust counselors who have an ACA certificate. The membership also keeps members informed on contemporary solutions to emerging issues through magazines, journals, newsletters, and news bulletins. Moreover, it gives unlimited access to professional development courses that can be used as credits during the licensure process (Yep, n.d). Lastly, the ACA-ACES Syllabus Clearinghouse helps counselors to progressively refresh their knowledge based on modern approaches and changes in the profession.

3. Requirements for Counselor Licensure in Georgia and Plan for Licensure and Certification

I plan to work in the state of Georgia where licensing requirements require interested persons to have graduate level education before submitting a formal application to the State’s board. Additionally, the applicant must not have a criminal record for proof of good character. Supervised work experience and passing of an exam are compulsory for individuals who wish to change status from Associate Licensed Professional Counselor (ALPC) to Licensed Professional Counselor (LPC).

A minimum of a master level education in a counseling-oriented field is required for licensure. However, the degree programs must be accredited by agencies that are recognized by the Council on Higher Education Accreditation (Counselor-License, n.d.). Counseling theory or psychotherapy is a mandatory subject of coverage by the applicant. Additionally, the coverage of at least six among the areas listed below is compulsory.

· Social and Cultural Foundations Comment by almcleod: See pages 64-65 in APA manual for how to format a bulleted list.

· Human Growth and Development

· Advanced Psychotherapy Intervention Theory

· Group Counseling Dynamics

· Career Development

· Research Methods

· Individual Appraisal

· Psychopathology

· Professional Orientation (Counselor-License, N.D.)

A minimum of 300 hours of internship that is supervised by an instructor is also compulsory. The board credits applicants for some course work that would be done after the masters. The board in Georgia also requires applicants to have relevant supervised practice that is dependent on the educational background. For instance, applicants holding a doctoral degree in a counseling-oriented program require only one-year internship to serve as proof of supervised practice (Counselor-License, n.d.). However, master’s level applicants should provide evidence of at least four years of supervised practice. The board gives credit for not more than one-year practicum experience acquired before the completion of a degree. The specialist degree in counseling amounts to two years of supervised practice along with an internship. Lastly, a master’s in vocational counseling translates to three years of supervision.

The number of years that one works as an associate are dependent on job status (full time or not) for the associate counselor. The director who is the employer and a supervisor are important figures during this type of employment. The supervisor must be recognized by the board and they evaluate performance and experience for licensure. For testing purposes, applicants must take either the National Counselors Examination or the National Clinical Mental Health Counseling Examination.

Counselors who have licenses from other states can access licensure in Georgia via endorsement provided the requirements in the previous state are higher or similar to Georgia’s.

For maintenance of the license, counselors are required to participate in 35 hours of education programs within every two years where professional ethics counts for at least five hours and the core areas of licensing at least 15 hours.

MY PLAN FOR LICENSURE Comment by almcleod: Also include estimated dates for each step.

My interest is to secure a counseling license in the state of Georgia and later surrounding states which will allow me to practice virtually and face to face. At first, I will present a notarized application to Georgia’s board to be recognized as an associate counselor. I will include the master’s program transcript, test scores, contact affidavit (director and supervisor), proof of internship and a processing fee.

After completion of the supervised practice, I will apply for the National Clinical Mental Health Counseling Examination. After the NBCC confirms my application, I will pay a fee of $195 and later select my testing center. Having met the requirement for licensure, I will formally apply to be considered an LPC. Lastly, to become a nationally certified counselor, I plan to complete a doctoral degree and later apply through the NBCC website.

4. Why Am I Here?

My journey into counseling is based on my mom being diagnosed with mental illness when I was five years old. Me Bbeing in foster care and living with several different family members left me vulnerable to all forms of abuse from the age of 5 until 18. I had issues with anger and I demonstrated passive aggressive behavior. I used comedy as a way to take the focus off me and I continuously conflicted with others. I was labeled an at-risk child. However, as an adult I went through a process of forgiveness and this process led me to going back to help others labeled as I was as a child.

I am therefore interested in helping people overcome deep rooted mental and emotional challenges. For this reason, I prefer to work with children and young adults who experience or witness domestic violence or abuse because it can have lasting consequences. I’m enthusiastic about the use of therapy to deconstruct internal conflicts and biases that can lower self-esteem or become stressors in an individual’s life. By pursuing a master’s program in a counseling related field, I stand a better chance in getting myself registered as a professional counselor. Thereafter, I would focus on helping people, especially children and teens who encounter scenes similar to mine.

On the other hand, being an African American woman, I am motivated to pursue CMH because the training equips counselors with multicultural skills that can be applied to diverse clientele. The percentage of counselors from the minority groups is significantly low. Therefore, I intend to use the multicultural skills to attend to clients from the minority groups where children encounter a relatively large number of stressors. For instance, Dettlaff (2010) argues that poverty and settlement related factors contribute to abuse of children in immigrant families. Interventions are therefore needed.

Counseling also entails a sequence of challenging but rewarding tasks. In this case, my goal in life is to help as many people as possible. The undertaking to help others creates a feeling of fulfillment and achievement. Indeed, helping people to change their behaviors and perceptions in a positive way that fosters the achievement of goals creates a rewarding experience.

On the other hand, being a patriotic citizen of my country, I would wish to help the victims of natural disasters or national crises such as the great depression. In natural disasters, the victims suffer from post-traumatic stress. Moreover, they are also vulnerable to depression due the drastic changes that occur in their lives. As a patriotic mental health counselor, I would devote my time and resources to ensure that such victims get a helper to aid them in regaining their lives. Similarly, during economic recessions, families face unprecedented changes due to the loss of jobs and livelihoods by the breadwinners. My goal would be to help the families (especially the children) to overcome the stress factors.

Lastly, the CACREP argues that counseling is a highly regarded profession. In this case, the prestige that is associated with the profession motivates the urge to help troubled young ones. In this case, I can easily identify with my profession as a mental health counselor.
