APA style
|
The Publication Manual of the American Psychological Association, Fifth Edition |
American Psychological Association (APA) style is a widely accepted format for writing research papers, particularly for social science manuscripts and
theses. APA style specifies, for example, the names and order of headings, formatting and organization of
citations and
references, and the arrangement of
tables,
figures,
footnotes, and
appendices.
APA style officially refers to
The Publication Manual of the American Psychological Association, a book of over 400 pages now in its fifth edition (ISBN 1-55798-791-2). It is published by the
American Psychological Association, which is the main scholarly organization for academic
psychologists in the
United States. A well-known alternative approach is the
MLA style manual.
Although adopting certain aspects of APA style may be resented by some authors, it is widely agreed that it serves a useful purpose. Uniform style across journals helps readers to navigate and access material more efficiently. Scholars who experience uncertainty when writing may find the
Manual a useful guide. For example, the "political correctness" sections of the manual discourage authors from writing prose that is abusive to women and minorities. Scholarly journals that require APA style sometimes let their authors deviate from it when it would increase clarity.
Following APA style, headings are used to organize articles and give them a hierarchical structure. APA style prescribes a specific format for headings (from one to five levels) within an article. They are referred to on page 113 of the 5th edition of the Publication Manual using the following level numbers:
*Level 5: CENTERED UPPERCASE HEADING
*Level 4:
Indented, italicized, lowercase paragraph heading ending with a period.*Level 3:
Flush Left, Italicized, Uppercase and Lowercase Side Heading*Level 2:
Centered, Italicized, Uppercase and Lowercase Heading*Level 1: Centered Uppercase and Lowercase Heading
According to APA style, if an article has:
*One level: use Level 1 headings
*Two levels: use Level 1 (superordinate) and Level 3 (subordinate) headings
*Three levels: use Level 1,
Level 3 and
Level 4 (from superordinate to subordinate)
*Four levels: use Level 1,
Level 2,
Level 3 and
Level 4 (from superordinate to subordinate)
*Five levels: use Level 5, Level 1,
Level 2,
Level 3 and
Level 4 (from superordinate to subordinate)
No guidelines are provided for articles with six or more levels of headings. Note that APA style does not permit preceding numbers or letters for the headings.
Reference citations in text are those which are referenced within a passage of text in the body of an article. APA style defines that a reference section may only include articles which are cited within the body of an article. This is the distinction between a document having a
Reference section and a
Bibliography which may incorporate sources which may have been read by the authors as background but not referred to or included in the body of a document.
APA follows a number of rules for formatting in-line citations, the following is not an exhaustive list as it does not cover quotations, nor all scenarios that may arise when referring to an article or document. Hopefully, it is enough to get a feel for how it is used.
*Single Author, Book, Journal, Published article, conference proceedings.: Format should be Author's last name (no initials) followed directly by a comma, then the year of publication. You may choose not to use enclosing brackets around the authors' names and refer to the article as part of a natural sentence (year should however normally remains enclosed). The same holds for multiple authors.
Social representations theory posits that reified scientific knowledge that exists at the boundaries of a given society, will be interpreted in meaningful and often simplified forms by the majority (Pauling, 2005).
Alternatively
Pauling (2005) posits that...
*Two Authors, Book, Journal, Published article, conference proceedings. Authors should be presented in order that they appear in the published article. If they are cited within closed brackets, use the ampersand (&) symbol between them. If not enclosed in brackets then use expanded "and".
Social representations theory posits that reified scientific knowledge that exists at the boundaries of a given society will be interpreted in meaningful and often simplified forms by the majority (Pauling & Liu, 2005).
Alternatively
Pauling and Liu (2005) posit that...
* Three or More Authors, Book, Journal, Published Article, Conference proceedings. At this point ambiguities and problems over various journals' interpretations and enforcement of various APA styles and editions becomes apparent. With three or more authors, it is expected that the first reference to an article contains all authors. Subsequent citations in the same document may refer to the article by the principal author only plus "et al." The general format is Author 1, Author 2, ... Author N & Author N + 1, normally in the order they appear in the publication, but sometimes listing the principle author, then the others in alphabetical order. The number of authors required for invoking the "et al. rule" is also often misused and misunderstood. (Note the reference section must contain ALL authors)

*Multiple publications same author
If an author has multiple publications which you wish to cite, you use a semi colon (;) to separate the years of publication in chronological order (oldest to most recent). If the publications occur in the same year, then you must denote this, using a suffix "a" or "b" is common (note you must also ensure that the "year field" in the reference section also contains the same suffix). For multiple authors, follow the same rules.
...majority (Pauling, 2004; 2005)
Alternatively...
Pauling (2004; 2005) suggests that...
*Multiple publications different authors
Follow the rules above as for same author, using a semicolon to separate articles. Citation should first be in Alphabetical order of the Author, then chronological.
...majority (Alford, 1995; Pauling, 2004; 2005; Sirkis, 2003)
The APA style guide asserts that bibliographies and other lists of names should be ordered by surname first, and mandates inclusion of surname prefixes. For example, "Martin de Rijke" should be sorted as "de Rijke, M.". For electronic references, websites and articles online for example, the APA Style website asserts some basic rules. The first is to direct readers specifically to the source material and the second is to provide references that work.
