Chapter 11: Presenting Your Research

American Psychological Association (APA) Style

Learning Objectives

• Define APA style and list several of its most important characteristics.
• Identify three levels of APA style and give examples of each.
• Identify multiple sources of information about APA style.

What Is APA Style?

APA style  is a set of guidelines for writing in psychology and related fields. These guidelines are set down in the Publication Manual of the American Psychological Association (APA, 2006) [1] . The  Publication Manual  originated in 1929 as a short journal article that provided basic standards for preparing manuscripts to be submitted for publication (Bentley et al., 1929) [2] . It was later expanded and published as a book by the association and is now in its seventh edition ( view the APA Style website online ). The primary purpose of APA style is to facilitate scientific communication by promoting clarity of expression and by standardizing the organization and content of research articles and book chapters. It is easier to write about research when you know what information to present, the order in which to present it, and even the style in which to present it. Likewise, it is easier to read about research when it is presented in familiar and expected ways.

APA style is best thought of as a “genre” of writing that is appropriate for presenting the results of psychological research—especially in academic and professional contexts. It is not synonymous with “good writing” in general. You would not write a literary analysis for an English class, even if it were based on psychoanalytic concepts, in APA style. You would write it in Modern Language Association (MLA) style instead. And you would not write a newspaper article, even if it were about a new breakthrough in behavioural neuroscience, in APA style. You would write it in Associated Press (AP) style instead. At the same time, you would not write an empirical research report in MLA style, in AP style, or in the style of a romance novel, an e-mail to a friend, or a shopping list. You would write it in APA style. Part of being a good writer in general is adopting a style that is appropriate to the writing task at hand, and for writing about psychological research, this is APA style.

The Levels of APA Style

Because APA style consists of a large number and variety of guidelines—the Publication Manual  is nearly 300 pages long—it can be useful to think about it in terms of three basic levels. The first is the overall  organization  of an article (which is covered in Chapter 2 “Manuscript Structure and Content” of the  Publication Manual ). Empirical research reports, in particular, have several distinct sections that always appear in the same order:

• Title page.  Presents the article title and author names and affiliations.
• Abstract.  Summarizes the research.
• Introduction.  Describes previous research and the rationale for the current study.
• Method.  Describes how the study was conducted.
• Results.  Describes the results of the study.
• Discussion.  Summarizes the study and discusses its implications.
• References.  Lists the references cited throughout the article.

The second level of APA style can be referred to as  high-level style  (covered in Chapter 3 “Writing Clearly and Concisely” of the  Publication Manual ), which includes guidelines for the clear expression of ideas. There are two important themes here. One is that APA-style writing is formal rather than informal. It adopts a tone that is appropriate for communicating with professional colleagues—other researchers and practitioners—who share an interest in the topic. Beyond this shared interest, however, these colleagues are not necessarily similar to the writer or to each other. A graduate student in British Columbia might be writing an article that will be read by a young psychotherapist in Toronto and a respected professor of psychology in Tokyo. Thus formal writing avoids slang, contractions, pop culture references, humour, and other elements that would be acceptable in talking with a friend or in writing informally.

The second theme of high-level APA style is that it is straightforward. This means that it communicates ideas as simply and clearly as possible, putting the focus on the ideas themselves and not on how they are communicated. Thus APA-style writing minimizes literary devices such as metaphor, imagery, irony, suspense, and so on. Again, humour is kept to a minimum. Sentences are short and direct. Technical terms must be used, but they are used to improve communication, not simply to make the writing sound more “scientific.” For example, if participants immersed their hands in a bucket of ice water, it is better just to write this than to write that they “were subjected to a pain-inducement apparatus.” At the same time, however, there is no better way to communicate that a between-subjects design was used than to use the term “between-subjects design.”

APA Style and the Values of Psychology

Robert Madigan and his colleagues have argued that APA style has a purpose that often goes unrecognized (Madigan, Johnson, & Linton, 1995) [3] . Specifically, it promotes psychologists’ scientific values and assumptions. From this perspective, many features of APA style that at first seem arbitrary actually make good sense. Following are several features of APA-style writing and the scientific values or assumptions they reflect.

Another important element of high-level APA style is the avoidance of language that is biased against particular groups. This is not only to avoid offending people—why would you want to offend people who are interested in your work?—but also for the sake of scientific objectivity and accuracy. For example, the term  sexual orientation  should be used instead of  sexual preference  because people do not generally experience their orientation as a “preference,” nor is it as easily changeable as this term suggests (APA Committee on Lesbian, Gay, and Bisexual Concerns Joint Task Force on Guidelines for Psychotherapy With Lesbian, Gay, and Bisexual Clients, 2000) [4] .

The general principles for avoiding biased language are fairly simple. First, be sensitive to labels by avoiding terms that are offensive or have negative connotations. This includes terms that identify people with a disorder or other problem they happen to have. For example,  patients with schizophrenia  is better than  schizophrenics . Second, use more specific terms rather than more general ones. For example,  Chinese Canadians  is better than  Asian Canadians  if everyone in the group is, in fact, Chinese Canadian. Third, avoid objectifying research participants. Instead, acknowledge their active contribution to the research. For example, “The  students completed  the questionnaire” is better than “The  subjects were administered  the questionnaire.” Note that this principle also makes for clearer, more engaging writing. Table 11.1 shows several more examples that follow these general principles.

The previous edition of the  Publication Manual  strongly discouraged the use of the term  subjects  (except for nonhumans) and strongly encouraged the use of participants  instead. The current edition, however, acknowledges that  subjects can still be appropriate in referring to human participants in areas in which it has traditionally been used (e.g., basic memory research). But it also encourages the use of more specific terms when possible:  university  students ,  children , respondents , and so on.

The third level of APA style can be referred to as  low-level style  (which is covered in Chapter 4 “The Mechanics of Style” through Chapter 7 “Reference Examples” of the  Publication Manual .) Low-level style includes all the specific guidelines pertaining to spelling, grammar, references and reference citations, numbers and statistics, figures and tables, and so on. There are so many low-level guidelines that even experienced professionals need to consult the  Publication Manual  from time to time. Table 11.2 contains some of the most common types of APA style errors based on an analysis of manuscripts submitted to one professional journal over a 6-year period (Onwuegbuzie, Combs, Slate, & Frels, 2010) [5] . These errors were committed by professional researchers but are probably similar to those that students commit the most too. See also Note 11.8 “Online APA Style Resources” in this section and, of course, the  Publication Manual  itself.

Online APA Style Resources

The best source of information on APA style is the Publication Manual itself. However, there are also many good websites on APA style, which do an excellent job of presenting the basics for beginning researchers. Here are a few of them.

APA-Style References and Citations

Because science is a large-scale collaboration among researchers, references to the work of other researchers are extremely important. Their importance is reflected in the extensive and detailed set of rules for formatting and using them.

At the end of an APA-style article or book chapter is a list that contains references  to all the works cited in the text (and  only  the works cited in the text). The reference list begins on its own page, with the heading “References,” centred in upper and lower case. The references themselves are then listed alphabetically according to the last names of the first named author for each citation. (As in the rest of an APA-style manuscript,  everything  is double-spaced.) Many different kinds of works might be cited in APA-style articles and book chapters, including magazine articles, websites, government documents, and even television shows. Of course, you should consult the  Publication Manual  or Online APA Style Resources for details on how to format them. Here we will focus on formatting references for the three most common kinds of works cited in APA style: journal articles, books, and book chapters.

Journal Articles

For journal articles, the generic format for a reference is as follows:

Author, A. A., Author, B. B., & Author, C. C. (year). Title of article.  Title of Journal, xx (yy), pp–pp. doi:xx.xxxxxxxxxx

Here is a concrete example:

Adair, J. G., & Vohra, N. (2003). The explosion of knowledge, references, and citations: Psychology’s unique response to a crisis.  American Psychologist, 58 (1), 15–23. doi: 10.1037/0003-066X.58.1.15

There are several things to notice here. The reference includes a hanging indent. That is, the first line of the reference is not indented but all subsequent lines are. The authors’ names appear in the same order as on the article, which reflects the authors’ relative contributions to the research. Only the authors’ last names and initials appear, and the names are separated by commas with an ampersand (&) between the last two. This is true even when there are only two authors. Only the first word of the article title is capitalized. The only exceptions are for words that are proper nouns or adjectives (e.g., “Freudian”) or if there is a subtitle, in which case the first word of the subtitle is also capitalized. In the journal title, however, all the important words are capitalized. The journal title and volume number are italicized; however, the issue number (listed within parentheses) is not. At the very end of the reference is the digital object identifier (DOI), which provides a permanent link to the location of the article on the Internet. Include this if it is available. It can generally be found in the record for the item on an electronic database (e.g., PsycINFO) and is usually displayed on the first page of the published article.

For a book, the generic format and a concrete example are as follows:

Author, A. A. (year).  Title of book . Location: Publisher. Kashdan, T., & Biswas-Diener, R. (2014). The upside of your dark side. New York, NY: Hudson Street Press.

Book Chapters

For a chapter in an edited book, the generic format and a concrete example are as follows:

Author, A. A., Author, B. B., & Author, C. C. (year). Title of chapter. In A. A. Editor, B. B. Editor, & C. C. Editor (Eds.),  Title of book  (pp. xxx–xxx). Location: Publisher. Lilienfeld, S. O., & Lynn, S. J. (2003). Dissociative identity disorder: Multiple personalities, multiple controversies. In S. O. Lilienfeld, S. J. Lynn, & J. M. Lohr (Eds.), Science and pseudoscience in clinical psychology (pp. 109–142). New York, NY: Guilford Press.

Notice that references for books and book chapters are similar to those for journal articles, but there are several differences too. For an edited book, the names of the editors appear with their first and middle initials followed by their last names (not the other way around)—with the abbreviation “Eds.” (or “Ed.,” if there is only one) appearing in parentheses immediately after the final editor’s name. Only the first word of a book title is capitalized (with the exceptions noted for article titles), and the entire title is italicized. For a chapter in an edited book, the page numbers of the chapter appear in parentheses after the book title with the abbreviation “pp.” Finally, both formats end with the location of publication and the publisher, separated by a colon.

Reference Citations

When you refer to another researcher’s idea, you must include a reference citation  (in the text) to the work in which that idea originally appeared and a full reference to that work in the reference list. What counts as an idea that must be cited? In general, this includes phenomena discovered by other researchers, theories they have developed, hypotheses they have derived, and specific methods they have used (e.g., specific questionnaires or stimulus materials). Citations should also appear for factual information that is not common knowledge so that other researchers can check that information for themselves. For example, in an article on the effect of cell phone usage on driving ability, the writer might cite official statistics on the number of cell phone–related accidents that occur each year. Among the ideas that do not need citations are widely shared methodological and statistical concepts (e.g., between-subjects design,  t  test) and statements that are so broad that they would be difficult for anyone to argue with (e.g., “Working memory plays a role in many daily activities.”). Be careful, though, because “common knowledge” about human behaviour is often incorrect. Therefore, when in doubt, find an appropriate reference to cite or remove the questionable assertion.

When you cite a work in the text of your manuscript, there are two ways to do it. Both include only the last names of the authors and the year of publication. The first method is to use the authors’ last names in the sentence (with no first names or initials) followed immediately by the year of publication in parentheses. Here are some examples:

Burger (2008) conducted a replication of Milgram’s (1963) original obedience study.

Although many people believe that women are more talkative than men, Mehl, Vazire, Ramirez-Esparza, Slatcher, and Pennebaker (2007) found essentially no difference in the number of words spoken by male and female college students.

Notice several things. First, the authors’ names are treated grammatically as names of people, not as things. It is better to write “a replication of Milgram’s (1963) study” than “a replication of Milgram (1963).” Second, when there are two authors the names are not separated by commas, but when there are three or more authors they are. Third, the word  and  (rather than an ampersand) is used to join the authors’ names. Fourth, the year follows immediately after the final author’s name. An additional point, which is not illustrated in these examples but is illustrated in the sample paper in Section 11.2 “Writing a Research Report in American Psychological Association (APA) Style”, is that the year only needs to be included the first time a particular work is cited in the same paragraph.

The second way to cite an article or a book chapter is parenthetically—including the authors’ last names and the year of publication in parentheses following the idea that is being credited. Here are some examples:

People can be surprisingly obedient to authority figures (Burger, 2008; Milgram, 1963).

Recent evidence suggests that men and women are similarly talkative (Mehl, Vazire, Ramirez-Esparza, Slatcher, & Pennebaker, 2007).

One thing to notice about such parenthetical citations is that they are often placed at the end of the sentence, which minimizes their disruption to the flow of that sentence. In contrast to the first way of citing a work, this way always includes the year—even when the citation is given multiple times in the same paragraph. Notice also that when there are multiple citations in the same set of parentheses, they are organized alphabetically by the name of the first author and separated by semicolons.

There are no strict rules for deciding which of the two citation styles to use. Most articles and book chapters contain a mixture of the two. In general, however, the first approach works well when you want to emphasize the person who conducted the research—for example, if you were comparing the theories of two prominent researchers. It also works well when you are describing a particular study in detail. The second approach works well when you are discussing a general idea and especially when you want to include multiple citations for the same idea.

The third most common error in Table 11.2 has to do with the use of  et al.  This is an abbreviation for the Latin term  et alia , which means “and others.” In APA style, if an article or a book chapter has more than two authors , you should include all their names when you first cite that work. After that, however, you should use the first author’s name followed by “et al.” Here are some examples:

Recall that Mehl et al. (2007) found that women and men spoke about the same number of words per day on average.

There is a strong positive correlation between the number of daily hassles and the number of symptoms people experience (Kanner et al., 1981).

Notice that there is no comma between the first author’s name and “et al.” Notice also that there is no period after “et” but there is one after “al.” This is because “et” is a complete word and “al.” is an abbreviation for the word  alia .

Key Takeaways

• APA style is a set of guidelines for writing in psychology. It is the genre of writing that psychologists use to communicate about their research with other researchers and practitioners.
• APA style can be seen as having three levels. There is the organization of a research article, the high-level style that includes writing in a formal and straightforward way, and the low-level style that consists of many specific rules of grammar, spelling, formatting of references, and so on.
• References and reference citations are an important part of APA style. There are specific rules for formatting references and for citing them in the text of an article.
• Practice: Find a description of a research study in a popular magazine, newspaper, blog, or website. Then identify five specific differences between how that description is written and how it would be written in APA style.

What is APA?

In this section we are going to look at how you can set up a paper in APA style. Specifically, we are going to look at citing books and journal articles within your research paper.

APA is the style of documentation of sources used by the American Psychological Association. This form of writing research papers is used mainly in the social sciences, like psychology, anthropology, sociology, as well as education and other fields.

How Does APA Style Work?

When working with APA there are two things to keep in mind: in-text citations and the reference page. In-text citations will use the author's name and the date within your research paper. These citations will refer back to the reference page at the end, which lists all the sources that you may have used in your research paper.

Note: If you are assigned a research paper in APA style for one of your courses, it's a good idea to ask your instructor the questions below. He or she will be able to explain details about the requirements for the paper. For now, we will go over the basic instructions of how to use in-text citations and how to set up the reference page.

When Would I Have to Cite a Source in APA?

Anytime you summarize, paraphrase, or quote information from another source, like passages from books or articles in an academic journal, you are required to list within your text the author's name and the year the article was published. There are a couple of ways this can be arranged. Here are a few examples.

• Another theory came from the idea of the “matching hypothesis.” This was presented by Goffman (1952), who believed that men had the tendency to choose spouses who were of similar social status. The sums of these attributes include are social skills, wealth, power, intelligence, attractiveness, and other skills that are valued in society.

With the example above, the writer puts the author's last name in the text and immediately after it puts the date in parentheses.

• In 1971 Berscheid, Dion, Walster, and Walster conducted another “computer date” dance. This time they paired similar attractive persons together for the date. An independent panel of judges assessed the attractiveness of each of the subjects.

Here, the authors' names and the date of publication are both put into the body of the text, without using parentheses.

Citing a Journal Article

If i cite a journal article in the body of my text does it mean that the authors of that journal article agree with the arguments in my paper.

No, not necessarily. Dr. Sadler, a professor in the psychology department at IUP, states that you can cite articles that will agree or disagree with your ideas. He goes on to say:

• The agreement or disagreement should be conveyed by your wording. For example, “This interpretation is consistent with findings by Smith and Jones (1999) . . . .” Or, you might say, “If my prediction is confirmed, it would falsify the theory of episodic memory proposed by Tulving (1984)” Or, “A number of researchers do not agree with this view (e.g., Brown, 1993; Stevens, 1992; Treisman, 1994).”

So, not only can you use journal articles to support your ideas, but you can also use them to show that some authors do not agree with your ideas or have ideas different from yours.

Preparing to Cite A Source

How do i let the reader know that i am about to cite a source.

To let the reader know that a journal article is about to be cited in the body of your paper, you can use signal phrases that are appropriate for the ideas you want to express. These words include: adds, argues, claims, denies, illustrates, grants, notes, observes, suggests, etc. You could also use the standard “said.”

This is expressed in the sample below:

• In an influential article, Terrace, Petitto, Sanders and Bever (1979) argued that the apes in the language experiments were not using language spontaneously but were merely imitating their trainers, responding to conscious or unconscious cues.

References Page

What is the references page and how is it put together.

The References page lists all the sources you have cited in your paper. The entry for a journal article should look like this:

• Berscheid, E., Dion, K. K., Walster, E., and Walster, G. W. (1971). Physical attractiveness and dating choice: A test of the matching hypothesis. Journal of Experimental Social Psychology , 7, 173-189.

As you can see in the example above, the authors' names appear first (last name, first name). Then the year of publication is given in parentheses. Then the title is listed (with only the first word of the title, the first word after the colon, and proper nouns capitalized). Then the name of the journal (in italics) is listed, the volume number, and finally, the pages of the article.

For a book, the entry looks like this:

• Schaller, G. B. (1993). The Last Panda . Chicago: University of Chicago Press.

In the example above, the author's name is listed (last name, first name), then the date, followed by the title with only the first word capitalized, the city of publication, and then the name of the publisher.
