The Writing Center
TO WRITING RESEARCH PAPERS
This style sheet is intended only as an overview and does not cover
all aspects of the APA style. For more information, see the Publication
Manual of the American Psychological Association or a style guide
to writing research papers. The Writing Center has these and other resources
on hand, and Writing Center tutors can help you to use them.
Always ask your mentor which style to use before you begin to write your paper.
The APA style refers to the method of writing research papers recommended by the American Psychological Association. The APA style is used in the social sciences and is governed by two basic ideas. The first is that a scientific paper attempts to show something that has already been proven true, so it calls for the past or present perfect tense when you cite the work of others. Second, the year of publication is important, so you need to feature it immediately after any named source in the text.
Smyth (1972) found that children often studied while watching television.
Williams and Maier (1994) have defined a new theory of cognition.
Use the present tense for generalizations and personal comments. Use the past or present perfect tenses only to introduce the work of cited sources.
Evidence of the rise of the heroin use exists for every age group, even children. Burroughs and Bruce (1996) reported on five incidents of heroin overdose in the under 10 age group.
Basic APA Facts
Plagiarism is the use of the words and/or ideas of another person without acknowledging the source. Plagiarism is generally grounds for failure of a course and can lead to dismissal from college. To avoid plagiarism, acknowledge your sources with in-text citations and a reference page. Enclose direct quotations in quotation marks or otherwise indent them from the body of your text. If you use another person's idea or paraphrase another person's words, be sure to use your own language and style of writing — don't simply rearrange the words. Use an in-text citation to acknowledge the source, then list on a reference page the publications or sources from which you obtained your citations. For more detailed information on plagiarism and how to avoid it, see the handout available at the GVC Writing Center.
Cite the first appearance of another person's words and/or ideas by introducing the quotation or paraphrase with the author's name. After the first appearance, cite the author's name either within the text of your writing or within the parenthetical citation immediately following the cited passage. Always use the last name of the author/authors and the year of publication. The year of publication always follows the name of the cited/quoted authority. Note that commas separate items within parentheses. Following are some examples of in-text citation methods in the APA style.
In his study of the effects of alcohol on the ability to drive, Smith (1991) showed that the reaction times of participating drivers were adversely affected by as little as a twelve ounce can of beer.
If you don't use the author's name in the text, place it within the parenthetical citation with the date.
A recent study of the effects of alcohol on the ability to drive showed that as little as twelve ounces of beer adversely affected the reaction time of participating drivers (Smith, 1991).
Provide a page number when you use an exact quotation. Use quotation marks. Use the singular "p." or the plural "pp." to indicate page number(s).
In his study on the effects of alcohol on drivers, Smith (1991, p. 104) stated that "participants who drank twelve ounces of beer with a 3.5% alcohol content reacted, on average, 1.2 seconds more slowly to an emergency braking situation than they did when they had not ingested alcohol."
As an alternative, place the page number within parentheses at the end of the quotation. If you do so, remember to place the date immediately after the author's name.
In his study on the effects of alcohol on drivers, Smith (1991) stated that "participants who drank twelve ounces of beer with a 3.5% alcohol content reacted, on average, 1.2 seconds more slowly to an emergency braking situation than they did when they had not ingested alcohol" (p. 104).
Indent a direct quotation of 40 or more words five spaces from the left margin. If the quotation includes more than one paragraph, indent the first line of succeeding paragraphs five more spaces (ten spaces total). Don't use quotation marks, and be sure to double space the quotation as well as your own writing.
In her study of adult patterns of television watching, Roberts (1996) reported the following behaviors:
Response behaviors exhibited by participants who watched television without any other persons present in the viewing room included imitating the facial expressions and hand movements of television characters as well as talking to individual characters. Affective behaviors included exhibitions of anger such as shouting and throwing magazines at the television.
Such behaviors were less evident behaviors in participants who watched television in groups of three. Instead, participants in group watching were more likely to interject critical or humorous comments regarding the content of particular television programs.
If you're citing an author who's been quoted in another book or article, use the original author's name in the text, and cite in parentheses the source in which you found the quotation.
Behavior is affected by situation. As Wallace (1972) postulated in Individual and Group Behavior, a person who acts a certain way independently may act in an entirely different manner while the member of a group (cited in Barkin, 1992, p. 478).
When citing a work with two, three, four, or five authors within the text of the paper, name them all in the first entry, e.g., (Smith, Andrews, & Lawrence 1995). After the first entry, cite only the first author's name followed by "et al.," for example, (Smith, et. al., 1995).
When citing a work with six or more authors, name only the first author followed by et. al., for example, (Fredericks, et. al., 1995). If the author is not given, use the first word or two of the title in the parenthetical citation.
Massachusetts state and municipal governments have initiated several programs to improve public safety, including community policing and after school activities ("Innovations," 1997).
If "Anonymous" is specified as the author, treat it as if it were a real name: (Anonymous, 1996). In the bibliographic references, also use the name Anonymous as author.
The Reference Page
You must always have a reference page as well as in-text citations to avoid plagiarism. The Reference Page immediately follows the text of the paper. Items on the reference page are listed alphabetically. Begin the first line of a reference at the left margin (i.e., do not indent the first line as you did in the body text). All subsequent lines for a reference should be indented one-half inch this is sometimes known as an "outdent" or "hanging indent"). APA has a second format that uses normal (one-half inch) indents on the first line of a reference, then left justifies subsequent lines to the left margin. This format is only for documents being submitted for publishing. Student papers should always use the first (hanging indent) format. For the reference page, use the running head and page number, then center the title "References" two lines below.
List the author's last name first with initial of the first name; year of publication in parentheses; title of book underlined (capitalize only the first word of the title and of any subtitle, and all proper nouns); the edition (if any) in parentheses; place of publication; and publisher. Omit the words Publishing Company and Inc. from the publisher's name. Use one space after periods and other punctuation.

Whereas you might not always be able to supply all the above information, follow the general APA format for the specific type of source you are citing (journal, article, chapter, book, etc.). Include all necessary information to allow the reader to access the source material.
The APA style requires an abstract, an 80 to 120 word summary of the contents of the paper that immediately follows the title page. Be sure to ask your mentor whether or not s/he requires an abstract. The abstract should include the purpose, thesis, and conclusions of your paper and be accurate, self-contained, concise, coherent, and readable. Do not use a paragraph indentation for the abstract. The abstract requires a separate page and immediately follows the title page.
APA format requires a title page that establishes a running head. Ask your Mentor if you need to provide a title page for your paper.
Each successive page will then have the running head "Addiction" followed by the page number in the upper right-hand corner.
