How to Write an APA Research Paper

Psychology/neuroscience 201, v iew in pdf format.

An APA-style paper includes the following sections: title page, abstract, introduction, method, results, discussion, and references. Your paper may also include one or more tables and/or figures. Different types of information about your study are addressed in each of the sections, as described below.

General formatting rules are as follows:

Do not put page breaks in between the introduction, method, results, and discussion sections.

The title page, abstract, references, table(s), and figure(s) should be on their own pages. The entire paper should be written in the past tense, in a 12-point font, double-spaced, and with one-inch margins all around.

(see sample on p. 41 of APA manual)

• Title should be between 10-12 words and should reflect content of paper (e.g., IV and DV).
• Title, your name, and Hamilton College are all double-spaced (no extra spaces)
• Create a page header using the “View header” function in MS Word. On the title page, the header should include the following: Flush left: Running head: THE RUNNING HEAD SHOULD BE IN ALL CAPITAL LETTERS. The running head is a short title that appears at the top of pages of published articles. It should not exceed 50 characters, including punctuation and spacing. (Note: on the title page, you actually write the words “Running head,” but these words do not appear on subsequent pages; just the actual running head does. If you make a section break between the title page and the rest of the paper you can make the header different for those two parts of the manuscript). Flush right, on same line: page number. Use the toolbox to insert a page number, so it will automatically number each page.

Abstract (labeled, centered, not bold)

No more than 120 words, one paragraph, block format (i.e., don’t indent), double-spaced.

• State topic, preferably in one sentence. Provide overview of method, results, and discussion.

Introduction

(Do not label as “Introduction.” Title of paper goes at the top of the page—not bold)

The introduction of an APA-style paper is the most difficult to write. A good introduction will summarize, integrate, and critically evaluate the empirical knowledge in the relevant area(s) in a way that sets the stage for your study and why you conducted it. The introduction starts out broad (but not too broad!) and gets more focused toward the end. Here are some guidelines for constructing a good introduction:

• Don’t put your readers to sleep by beginning your paper with the time-worn sentence, “Past research has shown (blah blah blah)” They’ll be snoring within a paragraph!  Try to draw your reader in by saying something interesting or thought-provoking right off the bat.  Take a look at articles you’ve read. Which ones captured your attention right away? How did the authors accomplish this task? Which ones didn’t?  Why not?  See if you can use articles you liked as a model. One way to begin (but not the only way) is to provide an example or anecdote illustrative of your topic area.
• Although you won’t go into the details of your study and hypotheses until the end of the intro, you should foreshadow your study a bit at the end of the first paragraph by stating your purpose briefly, to give your reader a schema for all the information you will present next.
• Your intro should be a logical flow of ideas that leads up to your hypothesis. Try to organize it in terms of the ideas rather than who did what when. In other words, your intro shouldn’t read like a story of “Schmirdley did such-and-such in 1991. Then Gurglehoff did something-or-other in 1993.  Then....(etc.)” First, brainstorm all of the ideas you think are necessary to include in your paper. Next, decide which ideas make sense to present first, second, third, and so forth, and think about how you want to transition between ideas. When an idea is complex, don’t be afraid to use a real-life example to clarify it for your reader. The introduction will end with a brief overview of your study and, finally, your specific hypotheses. The hypotheses should flow logically out of everything that’s been presented, so that the reader has the sense of, “Of course. This hypothesis makes complete sense, given all the other research that was presented.”
• When incorporating references into your intro, you do not necessarily need to describe every single study in complete detail, particularly if different studies use similar methodologies. Certainly you want to summarize briefly key articles, though, and point out differences in methods or findings of relevant studies when necessary. Don’t make one mistake typical of a novice APA-paper writer by stating overtly why you’re including a particular article (e.g., “This article is relevant to my study because…”). It should be obvious to the reader why you’re including a reference without your explicitly saying so.  DO NOT quote from the articles, instead paraphrase by putting the information in your own words.
• Be careful about citing your sources (see APA manual). Make sure there is a one-to-one correspondence between the articles you’ve cited in your intro and the articles listed in your reference section.
• Remember that your audience is the broader scientific community, not the other students in your class or your professor.  Therefore, you should assume they have a basic understanding of psychology, but you need to provide them with the complete information necessary for them to understand the research you are presenting.

Method (labeled, centered, bold)

The Method section of an APA-style paper is the most straightforward to write, but requires precision. Your goal is to describe the details of your study in such a way that another researcher could duplicate your methods exactly.

The Method section typically includes Participants, Materials and/or Apparatus, and Procedure sections. If the design is particularly complicated (multiple IVs in a factorial experiment, for example), you might also include a separate Design subsection or have a “Design and Procedure” section.

Note that in some studies (e.g., questionnaire studies in which there are many measures to describe but the procedure is brief), it may be more useful to present the Procedure section prior to the Materials section rather than after it.

Participants (labeled, flush left, bold)

Total number of participants (# women, # men), age range, mean and SD for age, racial/ethnic composition (if applicable), population type (e.g., college students). Remember to write numbers out when they begin a sentence.

• How were the participants recruited? (Don’t say “randomly” if it wasn’t random!) Were they compensated for their time in any way? (e.g., money, extra credit points)
• Write for a broad audience. Thus, do not write, “Students in Psych. 280...” Rather, write (for instance), “Students in a psychological statistics and research methods course at a small liberal arts college….”
• Try to avoid short, choppy sentences. Combine information into a longer sentence when possible.

Materials (labeled, flush left, bold)

Carefully describe any stimuli, questionnaires, and so forth. It is unnecessary to mention things such as the paper and pencil used to record the responses, the data recording sheet, the computer that ran the data analysis, the color of the computer, and so forth.

• If you included a questionnaire, you should describe it in detail. For instance, note how many items were on the questionnaire, what the response format was (e.g., a 5-point Likert-type scale ranging from 1 (strongly disagree) to 5 (strongly agree)), how many items were reverse-scored, whether the measure had subscales, and so forth. Provide a sample item or two for your reader.
• If you have created a new instrument, you should attach it as an Appendix.
• If you presented participants with various word lists to remember or stimuli to judge, you should describe those in detail here. Use subheadings to separate different types of stimuli if needed.  If you are only describing questionnaires, you may call this section “Measures.”

Apparatus (labeled, flush left, bold)

Include an apparatus section if you used specialized equipment for your study (e.g., the eye tracking machine) and need to describe it in detail.

Procedure (labeled, flush left, bold)

What did participants do, and in what order? When you list a control variable (e.g., “Participants all sat two feet from the experimenter.”), explain WHY you did what you did.  In other words, what nuisance variable were you controlling for? Your procedure should be as brief and concise as possible. Read through it. Did you repeat yourself anywhere? If so, how can you rearrange things to avoid redundancy? You may either write the instructions to the participants verbatim or paraphrase, whichever you deem more appropriate. Don’t forget to include brief statements about informed consent and debriefing.

Results (labeled, centered, bold)

In this section, describe how you analyzed the data and what you found. If your data analyses were complex, feel free to break this section down into labeled subsections, perhaps one section for each hypothesis.

• Include a section for descriptive statistics
• List what type of analysis or test you conducted to test each hypothesis.
• Refer to your Statistics textbook for the proper way to report results in APA style. A t-test, for example, is reported in the following format: t (18) = 3.57, p < .001, where 18 is the number of degrees of freedom (N – 2 for an independent-groups t test). For a correlation: r (32) = -.52, p < .001, where 32 is the number of degrees of freedom (N – 2 for a correlation). For a one-way ANOVA: F (2, 18) = 7.00, p < .001, where 2 represents the between and 18 represents df within Remember that if a finding has a p value greater than .05, it is “nonsignificant,” not “insignificant.” For nonsignificant findings, still provide the exact p values. For correlations, be sure to report the r 2 value as an assessment of the strength of the finding, to show what proportion of variability is shared by the two variables you’re correlating. For t- tests and ANOVAs, report eta 2 .
• Report exact p values to two or three decimal places (e.g., p = .042; see p. 114 of APA manual).  However, for p-values less than .001, simply put p < .001.
• Following the presentation of all the statistics and numbers, be sure to state the nature of your finding(s) in words and whether or not they support your hypothesis (e.g., “As predicted …”). This information can typically be presented in a sentence or two following the numbers (within the same paragraph). Also, be sure to include the relevant means and SDs.
• It may be useful to include a table or figure to represent your results visually. Be sure to refer to these in your paper (e.g., “As illustrated in Figure 1…”). Remember that you may present a set of findings either as a table or as a figure, but not as both. Make sure that your text is not redundant with your tables/figures. For instance, if you present a table of means and standard deviations, you do not need to also report these in the text. However, if you use a figure to represent your results, you may wish to report means and standard deviations in the text, as these may not always be precisely ascertained by examining the figure. Do describe the trends shown in the figure.
• Do not spend any time interpreting or explaining the results; save that for the Discussion section.

Discussion (labeled, centered, bold)

The goal of the discussion section is to interpret your findings and place them in the broader context of the literature in the area. A discussion section is like the reverse of the introduction, in that you begin with the specifics and work toward the more general (funnel out). Some points to consider:

• Begin with a brief restatement of your main findings (using words, not numbers). Did they support the hypothesis or not? If not, why not, do you think? Were there any surprising or interesting findings? How do your findings tie into the existing literature on the topic, or extend previous research? What do the results say about the broader behavior under investigation? Bring back some of the literature you discussed in the Introduction, and show how your results fit in (or don’t fit in, as the case may be). If you have surprising findings, you might discuss other theories that can help to explain the findings. Begin with the assumption that your results are valid, and explain why they might differ from others in the literature.
• What are the limitations of the study? If your findings differ from those of other researchers, or if you did not get statistically significant results, don’t spend pages and pages detailing what might have gone wrong with your study, but do provide one or two suggestions. Perhaps these could be incorporated into the future research section, below.
• What additional questions were generated from this study? What further research should be conducted on the topic? What gaps are there in the current body of research? Whenever you present an idea for a future research study, be sure to explain why you think that particular study should be conducted. What new knowledge would be gained from it?  Don’t just say, “I think it would be interesting to re-run the study on a different college campus” or “It would be better to run the study again with more participants.” Really put some thought into what extensions of the research might be interesting/informative, and why.
• What are the theoretical and/or practical implications of your findings? How do these results relate to larger issues of human thoughts, feelings, and behavior? Give your readers “the big picture.” Try to answer the question, “So what?

Final paragraph: Be sure to sum up your paper with a final concluding statement. Don’t just trail off with an idea for a future study. End on a positive note by reminding your reader why your study was important and what it added to the literature.

References (labeled, centered, not bold)

Provide an alphabetical listing of the references (alphabetize by last name of first author). Double-space all, with no extra spaces between references. The second line of each reference should be indented (this is called a hanging indent and is easily accomplished using the ruler in Microsoft Word). See the APA manual for how to format references correctly.

Examples of references to journal articles start on p. 198 of the manual, and examples of references to books and book chapters start on pp. 202. Digital object identifiers (DOIs) are now included for electronic sources (see pp. 187-192 of APA manual to learn more).

Journal article example: [Note that only the first letter of the first word of the article title is capitalized; the journal name and volume are italicized. If the journal name had multiple words, each of the major words would be capitalized.] 

Ebner-Priemer, U. W., & Trull, T. J. (2009). Ecological momentary assessment of mood disorders and mood dysregulation. Psychological Assessment, 21, 463-475. doi:10.1037/a0017075

Book chapter example: [Note that only the first letter of the first word of both the chapter title and book title are capitalized.]

Stephan, W. G. (1985). Intergroup relations. In G. Lindzey & E. Aronson (Eds.), The handbook of social psychology (3 rd ed., Vol. 2, pp. 599-658). New York: Random House.

Book example: Gray, P. (2010). Psychology (6 th ed.). New York: Worth

Table There are various formats for tables, depending upon the information you wish to include. See the APA manual. Be sure to provide a table number and table title (the latter is italicized). Tables can be single or double-spaced.

Figure If you have more than one figure, each one gets its own page. Use a sans serif font, such as Helvetica, for any text within your figure. Be sure to label your x- and y-axes clearly, and make sure you’ve noted the units of measurement of the DV. Underneath the figure provide a label and brief caption (e.g., “Figure 1. Mean evaluation of job applicant qualifications as a function of applicant attractiveness level”). The figure caption typically includes the IVs/predictor variables and the DV. Include error bars in your bar graphs, and note what the bars represent in the figure caption: Error bars represent one standard error above and below the mean.

In-Text Citations: (see pp. 174-179 of APA manual) When citing sources in your paper, you need to include the authors’ names and publication date.

You should use the following formats:

• When including the citation as part of the sentence, use AND: “According to Jones and Smith (2003), the…”
• When the citation appears in parentheses, use “&”: “Studies have shown that priming can affect actual motor behavior (Jones & Smith, 2003; Klein, Bailey, & Hammer, 1999).” The studies appearing in parentheses should be ordered alphabetically by the first author’s last name, and should be separated by semicolons.
• If you are quoting directly (which you should avoid), you also need to include the page number.
• For sources with three or more authors, once you have listed all the authors’ names, you may write “et al.” on subsequent mentions. For example: “Klein et al. (1999) found that….” For sources with two authors, both authors must be included every time the source is cited. When a source has six or more authors, the first author’s last name and “et al.” are used every time the source is cited (including the first time). 

Secondary Sources

“Secondary source” is the term used to describe material that is cited in another source. If in his article entitled “Behavioral Study of Obedience” (1963), Stanley Milgram makes reference to the ideas of Snow (presented above), Snow (1961) is the primary source, and Milgram (1963) is the secondary source.

Try to avoid using secondary sources in your papers; in other words, try to find the primary source and read it before citing it in your own work. If you must use a secondary source, however, you should cite it in the following way:

Snow (as cited in Milgram, 1963) argued that, historically, the cause of most criminal acts... The reference for the Milgram article (but not the Snow reference) should then appear in the reference list at the end of your paper.

Using Biometrics to Evaluate Visual Design

Jane Lisa Dekker

Art Department, Northern California Valley State University

UXAD 272: Strategic Web Design

Professor Juan Liu, PhD

January 29, 2020

      A vast amount of research has been conducted regarding the importance of visual design, and its role as a mediator of user’s experience when browsing a site or interacting with an interface. In the literature, visual design is one aspect of website quality. Jones and Kim (2010) define website quality as “the perceived quality of a retail website that involves a [user’s] perceptions of the retailer’s website and comprises consumer reactions towards such attributes as information, entertainment/enjoyment, usability, transaction capabilities, and design aesthetics” (p. 632).  They further examined the impact web quality and retail brand trust has on purchase intentions. Additional research examining e-commerce sites has shown web quality has an impact on both initial and continued purchase intention (Kuan, Bock, & Vathanophas, 2008), as well as consumer satisfaction (Lin, 2007). Moreso, research on the relationship between visual design and perceived usability (Stojmenovic, Pilgrim, & Lindgaard, 2014) has revealed a positive correlation between the two. As users’ ratings of visual quality increase, their ratings of perceived usability follows a similar trend. Although this research spans various domains, the reliance on self-report measures to gauge concepts like visual design and web quality is prevalent throughout much of the literature.

Although some self-report scales are validated within the literature, there are still issues with the use of self-report questionnaires. One is the reliance on the honesty of the participant. This tends to be more of an issue in studies related to questionnaires that measure characteristics of the participant, rather than objective stimuli. More relevant to this study is the issue of introspection and memory. Surveys are often distributed after a task is completed, and its accuracy is dependent on the ability of the participant to remember their experience during the study. Multiple research studies have shown that human memory is far from static. This can

be dangerous if a researcher chooses to solely rely on self-report methods to test a hypothesis. We believe these self-report methods in tandem with biometric methods can help ensure the validity of the questionnaires, and provide information beyond the scope of self-report scales.

Research Questions

      We know from previous research that the quality of websites mediates many aspects of e-commerce, and provides insight as to how consumers view the webpages in general.  However, simply knowing a webpage is perceived as lower quality doesn’t give insight as to what aspects of a page are disliked by a user. Additionally, it’s possible that the user is misremembering aspects of the webpage or being dishonest in their assessment. Using eye tracking metrics, galvanic skin response, and facial expression measures in tandem with a scale aimed at measuring visual design quality has a couple of identifiable benefits. Using both can potentially identify patterns amongst the biometric measures and the questionnaire, which would strengthen the validity of the results. More so, the eye tracking data has the potential to identify patterns amongst websites of lower or higher quality.

If found, these patterns can be used to evaluate particular aspects of a page that are impacting the quality of a webpage. Overall, we are interested in answering two questions:

Research Question 1 : Can attitudinal changes regarding substantial website redesigns be captured using biometric measures?

Research Question 2 : How do biometric measures correlate with self-reported measures of visual appeal?

      Answering these questions has the potential to provide a method of justification for design changes, ranging from minor tweak to complete rebrands. There is not an easy way for companies to quantitatively analyze visual design decisions. A method for doing so would help companies evaluate visual designs before implementation in order to cost-justify them. To this end, we hope to demonstrate that biometric measurements can be used with questionnaires to verify and validate potential design changes a company or organization might want to implement.

      By examining data from test subjects during a brief exposure to several websites, we hoped to explore the relationship between the self-reported evaluation of visual design quality and key biometric measurements of a subject’s emotional valence and arousal. Subjects were exposed to ten pairs of websites before and after a substantial visual design change and asked to evaluate the website based on their initial impressions of the site’s visual design quality using the VisAWI-S scale, as shown in Table 1.  

During this assessment we collected GSR, facial expressions (limited by errors in initial study configuration), pupillary response, and fixation data using iMotions software coupled with a Tobii eye tracker, Shimmer GSR device, and Affdex facial expression analysis toolkit. This data was analyzed, in Table 2, to discover relationships between the independent and dependent variables, as well as relationships between certain dependent variables.

How to Write a Research Paper in APA Format — A Complete Guide

Completed your research experiments and collated your results? Does it feel like you have crossed a major hurdle in your research journey? No, not even close! What lies next is — publishing your research work for it to reach the science world! The process of publishing a research paper is so intricate, if you miss one aspect, you could end up struggling with revisions and reworks or getting a rejection! Thus, there is a necessity of following an exceptional mode of writing. The APA style research format comes to a researcher’s rescue.

This article discusses how to effortlessly write an APA style research paper and how it is necessary to understand the basic elements of APA style research paper in order to write an article in APA style research format.

Table of Contents

What Is APA Style?

The APA format is the official style of American Psychological Association (APA) and is commonly used to cite sources in psychology, education and social sciences. APA research paper format is widely used in the research publishing industry.

Students and researchers usually get confused with various research paper writing formats and are unclear about the requirements from the research publication journals. Therefore, the best way to deal with beginning to write a research paper is to first know the journal’s requirement and then follow the guidelines accordingly.

Though the reference section may change over the course of time, the information related to the other sections in APA research paper format is similar and could be referred to, for writing an exemplary research paper.

Guidelines for APA Style Paper (7th edition)

An APA style research format is different as compared to a term paper, a creative writing paper, a composition-style paper, or a thought paper. Throughout the paper you need to apply these guidelines while writing the paper –

Page Layout:

Type the content and keep double-space on standard-sized paper (8.5” x 11”), with 1” margins on all sides.

You should indent the first line of every paragraph 0.5 inches

Include a page number on every page.

You could use an accessible font like Times New Roman 12pt., Arial 11pt., or Georgia 11pt.

APA Research Paper Sections

The APA research paper format is based on seven main components: title page, abstract, introduction, methods, results, discussion, and references. The sections in APA-style paper are as follows:

1. Title Page

As per the APA research paper format, the title should be between 10-12 words and should reflect the essence of the paper. After writing the title, write your name followed by name of the college. Furthermore, create a page header using the “View Header” function in MS Word and on the title page include a running head — a short title that appears at the top of pages of published articles (flush left) and page number on the same line (flush right). The running head should not exceed 50 characters, including punctuation and spacing. Moreover, you could use the toolbox to insert a page number, so that it automatically numbers each page.

2. Abstract

Abstract should contain no more than 120 words , and should be one paragraph written in block format with double spacing. Additionally, state the topic in a sentence or two. Also, provide overview of methods, results, and discussion.

APA Style – Abstract in APA Style

3. Introduction

An introduction of APA research paper format is the most difficult section to write. A good introduction critically evaluates the empirical knowledge in the relevant area(s) in a way that defines the knowledge gap and expresses your aim for your study and why you conducted it. However, the challenge here is to keep the reader’s interest in reading your paper.

A good introduction keeps readers engaged with your paper. For writing an interesting introduction, researchers should introduce logical flow of ideas which will eventually lead to the research hypothesis . Furthermore, while incorporating references into your introduction, do not describe every single study in complete detail. Summarize the key findings from the article and do not quote from the articles, instead paraphrase the content .

The method section in APA research paper format is straightforward. However, the protocol and requirements should be mentioned precisely. The goal of this section is to describe your study and experiments in detail, so that there is no issue in reproducibility of results and other researchers could duplicate your methods effectively.

This section includes Materials and/or Apparatus and Experiments/Procedures/Protocols. Furthermore, keep the procedures brief and accurate, and make sure to read through so as to not repeat the steps or avoid redundancy.

In this section, you could describe how you analyzed the data and explain your findings. If your data analyses are complex, then break the section into subsections, ideally a subsection for each hypothesis and elaborate the subsections by using statistical analysis and including tables or figures to represent results visually. Most importantly, do not share interpretation of the results here. You can interpret and explain the results in the discussion section.

6. Discussion

Results are interpreted and understood in this section. Discussion section helps understand the research hypothesis better and places the results in the broader context of the literature in the area. This section is the reversal of introduction section, wherein you begin with the specifics and explain the general understanding of the topics.

In discussion, you start with a brief of your main findings, followed by explaining if your research findings support your hypothesis. Furthermore, you could explain how your findings enhance or support the existing literature on the topic. Connect your results with some of the literature mentioned in the introduction to bring your story back to full circle. You could also mention if there are any interesting or surprising findings in your results. Discuss other theories which could help you justify your surprising results.

Explain the limitation of your study and mention all the additional questions that were generated from your study. You could also mention what further research should be conducted on the topic and what are the knowledge gaps in the current body of research. Finally, mention how your results could relate to the larger issues of human existence and highlight “the big picture” for your readers.

7. References

Provide an alphabetical listing of the references. Do not keep extra spaces between references and double-space all the references. The second line of each reference should be intended. You could refer to the examples (mentioned below) to know how to format references correctly.

I. Journal Article:

Only first letter of the first word of the article title is capitalized; the journal name and volume are italicized. If the journal name had multiple words, each of the major words are capitalized.

Example: Ebner-Priemer, U. W., & Trull, T. J. (2009). Ecological momentary assessment of mood disorders and mood dysregulation. Psychological Assessment, 21 , 463-475. doi:10.1037/a0017075

II. Book Chapter:

Only the first letter of the first word of both the chapter title and book title are capitalized.

Example: Stephan, W. G. (1985). Intergroup relations. In G. Lindzey & E. Aronson (Eds.), The handbook of social psychology (3rd ed., Vol. 2, pp. 599-658). New York: Random House.

Example: Gray, P. (2010). Psychology (6th ed.). New York: Worth

There are various formats for tables, depending upon the information you wish to include. So, be thorough and provide a table number and title (the latter should be italicized). Tables can be single or double-spaced.

Be sure to mention x- and y-axes clearly. Underneath the figure provide a label and brief caption. The figure caption typically includes variables and units of measurements. Also, include error bars in your bar graphs, and note what the bars represent in the figure caption – Error bars represent one standard error above and below the mean.

VI. In-Text Citation:

• Mention the authors’ names and publication date while citing sources in your paper.
• When including the citation as part of the sentence, use AND: “According to Jones and Smith (2003), the…”
• When the citation is written in parentheses, use &: “Studies have shown that priming can affect actual motor behavior (Jones & Smith, 2003; Kiley, Bailey, & Hammer, 1999). The studies in parentheses should appear alphabetically by first author’s last name, and separate it with semicolons.
• You should avoid quoting directly, but in case you do – along with the name and date, include the page number.
• For sources with three or more authors, once you have listed all the authors’ names, you may write “et al.” on subsequent mentions: “Klein et al. (1999) found that…”.
• Meanwhile, when source has six or more authors, the first author’s last name and “et al.” are used every time the source is cited.

VII. Secondary Source:

It is a term used to describe material that is cited in another source. Avoid using secondary sources in your papers. Try to find the primary source and read it before citing in your work. However, if you must mention a secondary source, refer to the APA style paper example below:

Primary source author’s last name (as cited in secondary source author’s last name, year) argued that…

7 Tips for Writing an Error-free APA Style Research Paper

• Although there are exceptions, minimize using first person while writing.
• Avoid including personal statements or anecdotes.
• Although there are exceptions, use past tense while writing.
• Do not use contractions. (e.g., “it does not follow” rather than “it doesn’t follow”)
• Avoid biased language – Be updated with appropriate terminologies, especially if you are writing a paper that includes gender, race, ethnicity, sexual orientation, etc.
• Be certain to cite your sources.
• Try to paraphrase as much as possible, and do not directly quote from source articles.

This article contains only a few aspects of an APA research paper format. There are many APA style rules which can be explored before you begin to write an APA style research paper. Many of the APA research paper format rules are dynamic and subject to change, so it is best to refer to 7 th edition (latest) of the APA Publication Manual and be thorough with every section’s format before writing a research paper.

Frequently Asked Questions

The APA format is the official style of American Psychological Association (APA) and is commonly used to cite sources in psychology, education and social sciences.

APA stands for the American Psychological Association. It is a professional organization that focuses on the field of psychology and related disciplines.

Citing sources in APA format involves specific guidelines for different types of sources. In-text Citations: For a paraphrased or summarized idea from a source, include the author's last name and the publication year in parentheses. Example: (Smith, 2021) Reference List Entry for a Journal Article: Only first letter of the first word of the article title is capitalized; the journal name and volume are italicized. If the journal name had multiple words, each of the major words are capitalized. Example: Ebner-Priemer, U. W., & Trull, T. J. (2009). Ecological momentary assessment of mood disorders and mood dysregulation. Psychological Assessment, 21, 463-475. doi:10.1037/a0017075

The APA (American Psychological Association) style is primarily used by researchers, scholars, and students in the social sciences, including psychology, sociology, education, and related fields. However, the APA style is not limited to these disciplines and is also used in other academic and scientific fields when writing research papers or scholarly articles.

As per the 7th edition of APA citation (published in 2020), the last name and first/middle initials for all authors (up to first 20 authors) are mentioned in the bibliography. If there are 21 or more authors, an ellipsis (but no ampersand) is used after the 19th author, and then the final author’s name is added. Generic format: Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article. Title of Journal, Volume # (issue number), Pages. https://doi.org/xx.xxx/yyyy Example: Ebner-Priemer, U. W., & Trull, T. J. (2009). Ecological momentary assessment of mood disorders and mood dysregulation. Psychological Assessment, 21, 463-475. doi:10.1037/a0017075

When quoting in APA format, you need to properly incorporate and cite direct quotations from sources. Introduce the Quote: Begin with a signal phrase or an introductory statement to lead into the quote. This helps provide context and relevance for the quotation. Provide In-text Citation: Immediately after the closing quotation mark, include an in-text citation that provides the author's last name, publication year, and, if applicable, page number(s) of the quoted material. Example: (Smith, 2021, p. 25) Cite the Source in the Reference List: Include a corresponding entry in the reference list for the source you are quoting. The format for the reference list entry depends on the type of source being quoted (e.g., book, journal article, website).

13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

Today, we’re excited to share the first two models of the next generation of Llama, Meta Llama 3, available for broad use. This release features pretrained and instruction-fine-tuned language models with 8B and 70B parameters that can support a broad range of use cases. This next generation of Llama demonstrates state-of-the-art performance on a wide range of industry benchmarks and offers new capabilities, including improved reasoning. We believe these are the best open source models of their class, period. In support of our longstanding open approach, we’re putting Llama 3 in the hands of the community. We want to kickstart the next wave of innovation in AI across the stack—from applications to developer tools to evals to inference optimizations and more. We can’t wait to see what you build and look forward to your feedback.

Our goals for Llama 3

With Llama 3, we set out to build the best open models that are on par with the best proprietary models available today. We wanted to address developer feedback to increase the overall helpfulness of Llama 3 and are doing so while continuing to play a leading role on responsible use and deployment of LLMs. We are embracing the open source ethos of releasing early and often to enable the community to get access to these models while they are still in development. The text-based models we are releasing today are the first in the Llama 3 collection of models. Our goal in the near future is to make Llama 3 multilingual and multimodal, have longer context, and continue to improve overall performance across core LLM capabilities such as reasoning and coding.

State-of-the-art performance

Our new 8B and 70B parameter Llama 3 models are a major leap over Llama 2 and establish a new state-of-the-art for LLM models at those scales. Thanks to improvements in pretraining and post-training, our pretrained and instruction-fine-tuned models are the best models existing today at the 8B and 70B parameter scale. Improvements in our post-training procedures substantially reduced false refusal rates, improved alignment, and increased diversity in model responses. We also saw greatly improved capabilities like reasoning, code generation, and instruction following making Llama 3 more steerable.

*Please see evaluation details for setting and parameters with which these evaluations are calculated.

In the development of Llama 3, we looked at model performance on standard benchmarks and also sought to optimize for performance for real-world scenarios. To this end, we developed a new high-quality human evaluation set. This evaluation set contains 1,800 prompts that cover 12 key use cases: asking for advice, brainstorming, classification, closed question answering, coding, creative writing, extraction, inhabiting a character/persona, open question answering, reasoning, rewriting, and summarization. To prevent accidental overfitting of our models on this evaluation set, even our own modeling teams do not have access to it. The chart below shows aggregated results of our human evaluations across of these categories and prompts against Claude Sonnet, Mistral Medium, and GPT-3.5.

Preference rankings by human annotators based on this evaluation set highlight the strong performance of our 70B instruction-following model compared to competing models of comparable size in real-world scenarios.

Our pretrained model also establishes a new state-of-the-art for LLM models at those scales.

To develop a great language model, we believe it’s important to innovate, scale, and optimize for simplicity. We adopted this design philosophy throughout the Llama 3 project with a focus on four key ingredients: the model architecture, the pretraining data, scaling up pretraining, and instruction fine-tuning.

Model architecture

In line with our design philosophy, we opted for a relatively standard decoder-only transformer architecture in Llama 3. Compared to Llama 2, we made several key improvements. Llama 3 uses a tokenizer with a vocabulary of 128K tokens that encodes language much more efficiently, which leads to substantially improved model performance. To improve the inference efficiency of Llama 3 models, we’ve adopted grouped query attention (GQA) across both the 8B and 70B sizes. We trained the models on sequences of 8,192 tokens, using a mask to ensure self-attention does not cross document boundaries.

Training data

To train the best language model, the curation of a large, high-quality training dataset is paramount. In line with our design principles, we invested heavily in pretraining data. Llama 3 is pretrained on over 15T tokens that were all collected from publicly available sources. Our training dataset is seven times larger than that used for Llama 2, and it includes four times more code. To prepare for upcoming multilingual use cases, over 5% of the Llama 3 pretraining dataset consists of high-quality non-English data that covers over 30 languages. However, we do not expect the same level of performance in these languages as in English.

To ensure Llama 3 is trained on data of the highest quality, we developed a series of data-filtering pipelines. These pipelines include using heuristic filters, NSFW filters, semantic deduplication approaches, and text classifiers to predict data quality. We found that previous generations of Llama are surprisingly good at identifying high-quality data, hence we used Llama 2 to generate the training data for the text-quality classifiers that are powering Llama 3.

We also performed extensive experiments to evaluate the best ways of mixing data from different sources in our final pretraining dataset. These experiments enabled us to select a data mix that ensures that Llama 3 performs well across use cases including trivia questions, STEM, coding, historical knowledge, etc.

Scaling up pretraining

To effectively leverage our pretraining data in Llama 3 models, we put substantial effort into scaling up pretraining. Specifically, we have developed a series of detailed scaling laws for downstream benchmark evaluations. These scaling laws enable us to select an optimal data mix and to make informed decisions on how to best use our training compute. Importantly, scaling laws allow us to predict the performance of our largest models on key tasks (for example, code generation as evaluated on the HumanEval benchmark—see above) before we actually train the models. This helps us ensure strong performance of our final models across a variety of use cases and capabilities.

We made several new observations on scaling behavior during the development of Llama 3. For example, while the Chinchilla-optimal amount of training compute for an 8B parameter model corresponds to ~200B tokens, we found that model performance continues to improve even after the model is trained on two orders of magnitude more data. Both our 8B and 70B parameter models continued to improve log-linearly after we trained them on up to 15T tokens. Larger models can match the performance of these smaller models with less training compute, but smaller models are generally preferred because they are much more efficient during inference.

To train our largest Llama 3 models, we combined three types of parallelization: data parallelization, model parallelization, and pipeline parallelization. Our most efficient implementation achieves a compute utilization of over 400 TFLOPS per GPU when trained on 16K GPUs simultaneously. We performed training runs on two custom-built 24K GPU clusters . To maximize GPU uptime, we developed an advanced new training stack that automates error detection, handling, and maintenance. We also greatly improved our hardware reliability and detection mechanisms for silent data corruption, and we developed new scalable storage systems that reduce overheads of checkpointing and rollback. Those improvements resulted in an overall effective training time of more than 95%. Combined, these improvements increased the efficiency of Llama 3 training by ~three times compared to Llama 2.

Instruction fine-tuning

To fully unlock the potential of our pretrained models in chat use cases, we innovated on our approach to instruction-tuning as well. Our approach to post-training is a combination of supervised fine-tuning (SFT), rejection sampling, proximal policy optimization (PPO), and direct preference optimization (DPO). The quality of the prompts that are used in SFT and the preference rankings that are used in PPO and DPO has an outsized influence on the performance of aligned models. Some of our biggest improvements in model quality came from carefully curating this data and performing multiple rounds of quality assurance on annotations provided by human annotators.

Learning from preference rankings via PPO and DPO also greatly improved the performance of Llama 3 on reasoning and coding tasks. We found that if you ask a model a reasoning question that it struggles to answer, the model will sometimes produce the right reasoning trace: The model knows how to produce the right answer, but it does not know how to select it. Training on preference rankings enables the model to learn how to select it.

Building with Llama 3

Our vision is to enable developers to customize Llama 3 to support relevant use cases and to make it easier to adopt best practices and improve the open ecosystem. With this release, we’re providing new trust and safety tools including updated components with both Llama Guard 2 and Cybersec Eval 2, and the introduction of Code Shield—an inference time guardrail for filtering insecure code produced by LLMs.

We’ve also co-developed Llama 3 with torchtune , the new PyTorch-native library for easily authoring, fine-tuning, and experimenting with LLMs. torchtune provides memory efficient and hackable training recipes written entirely in PyTorch. The library is integrated with popular platforms such as Hugging Face, Weights & Biases, and EleutherAI and even supports Executorch for enabling efficient inference to be run on a wide variety of mobile and edge devices. For everything from prompt engineering to using Llama 3 with LangChain we have a comprehensive getting started guide and takes you from downloading Llama 3 all the way to deployment at scale within your generative AI application.

A system-level approach to responsibility

We have designed Llama 3 models to be maximally helpful while ensuring an industry leading approach to responsibly deploying them. To achieve this, we have adopted a new, system-level approach to the responsible development and deployment of Llama. We envision Llama models as part of a broader system that puts the developer in the driver’s seat. Llama models will serve as a foundational piece of a system that developers design with their unique end goals in mind.

Instruction fine-tuning also plays a major role in ensuring the safety of our models. Our instruction-fine-tuned models have been red-teamed (tested) for safety through internal and external efforts. ​​Our red teaming approach leverages human experts and automation methods to generate adversarial prompts that try to elicit problematic responses. For instance, we apply comprehensive testing to assess risks of misuse related to Chemical, Biological, Cyber Security, and other risk areas. All of these efforts are iterative and used to inform safety fine-tuning of the models being released. You can read more about our efforts in the model card .

Llama Guard models are meant to be a foundation for prompt and response safety and can easily be fine-tuned to create a new taxonomy depending on application needs. As a starting point, the new Llama Guard 2 uses the recently announced MLCommons taxonomy, in an effort to support the emergence of industry standards in this important area. Additionally, CyberSecEval 2 expands on its predecessor by adding measures of an LLM’s propensity to allow for abuse of its code interpreter, offensive cybersecurity capabilities, and susceptibility to prompt injection attacks (learn more in our technical paper ). Finally, we’re introducing Code Shield which adds support for inference-time filtering of insecure code produced by LLMs. This offers mitigation of risks around insecure code suggestions, code interpreter abuse prevention, and secure command execution.

With the speed at which the generative AI space is moving, we believe an open approach is an important way to bring the ecosystem together and mitigate these potential harms. As part of that, we’re updating our Responsible Use Guide (RUG) that provides a comprehensive guide to responsible development with LLMs. As we outlined in the RUG, we recommend that all inputs and outputs be checked and filtered in accordance with content guidelines appropriate to the application. Additionally, many cloud service providers offer content moderation APIs and other tools for responsible deployment, and we encourage developers to also consider using these options.

Deploying Llama 3 at scale

Llama 3 will soon be available on all major platforms including cloud providers, model API providers, and much more. Llama 3 will be everywhere .

Our benchmarks show the tokenizer offers improved token efficiency, yielding up to 15% fewer tokens compared to Llama 2. Also, Group Query Attention (GQA) now has been added to Llama 3 8B as well. As a result, we observed that despite the model having 1B more parameters compared to Llama 2 7B, the improved tokenizer efficiency and GQA contribute to maintaining the inference efficiency on par with Llama 2 7B.

For examples of how to leverage all of these capabilities, check out Llama Recipes which contains all of our open source code that can be leveraged for everything from fine-tuning to deployment to model evaluation.

What’s next for Llama 3?

The Llama 3 8B and 70B models mark the beginning of what we plan to release for Llama 3. And there’s a lot more to come.

Our largest models are over 400B parameters and, while these models are still training, our team is excited about how they’re trending. Over the coming months, we’ll release multiple models with new capabilities including multimodality, the ability to converse in multiple languages, a much longer context window, and stronger overall capabilities. We will also publish a detailed research paper once we are done training Llama 3.

To give you a sneak preview for where these models are today as they continue training, we thought we could share some snapshots of how our largest LLM model is trending. Please note that this data is based on an early checkpoint of Llama 3 that is still training and these capabilities are not supported as part of the models released today.

We’re committed to the continued growth and development of an open AI ecosystem for releasing our models responsibly. We have long believed that openness leads to better, safer products, faster innovation, and a healthier overall market. This is good for Meta, and it is good for society. We’re taking a community-first approach with Llama 3, and starting today, these models are available on the leading cloud, hosting, and hardware platforms with many more to come.
