Referencing Style (APA) for Writing Papers


Referencing will follow the APA (American Psychological Association) style.  A list of all journals used should be included at the end of the report (also APA style).  Only this style of referencing is acceptable.


·       APA journals use the author-date method of citation; that is, the surname of the author and the year of publication are inserted in the text at the appropriate point:


            Smith (1993) compared reaction times

            In a recent study (Smith, 1993) of reaction times


·       When a work has more than two authors and fewer than six authors, cite all authors the first time the reference occurs; in subsequent citations include only the surnamen of the first author followed by “et al.” (not underlined and with no period after “et”) and year:


            Williams, Jones, Smith, Bradner and Torrington (1995) found <first citation>

            Williams et al. (1995) found <subsequent citations>

            In a recent study (Williams et al., 1995), it was found that...


·       Join the names in a multiple-author citation in running text by the word and.  In parenthetical material, in tables and in the reference list, join the names by an ampersand (&):


   James and Ryerson (1991) demonstrated.

   has been demonstrated (James & Ryerson, 1991).


·       List two or more works by different authors who are cited within the same parentheses in alphabetical order by the first author’s surname.  Separate the citations by semicolons.


            Several studies (Dorow & O’Neal, 1989; Mullaney, 1988; Talpers, 1991)...


·       To cite a specific part of a source, indicate the page, chapter, figure, table or equation at the appropriate point in the text.  Always give page numbers for quotations.  Note that the words, page and chapter are abbreviated in such text citations:


            (Czapiewski & Ruby, 1988, p.10)

            (Wilmarth, 1990, chap. 3)

Referencing Web Site Material


The variety of material available on the Web, and the variety of ways in which it is structured and presented, can present challenges for creating usable and useful  references. Regardless of format, however, authors using and citing Internet sources should observe the following two guidelines:


1.     Direct readers as closely as possible to the information being cited; whenever possible, reference specific documents rather than home or menu pages.


2.     Provide addresses that work.


At a minimum, a reference of an Internet source should provide a document title or  description, a date (either the date of publication or update or the date of retrieval), and an address (in Internet terms, a uniform resource locator, or URL). Whenever possible, identify the authors of a document as well.

Citations in Text of Electronic Material


            To cite a specific part of a source, indicate the page, chapter, figure, table, or equation at the  appropriate point in text. Always give page numbers for quotations.  Note that the words page and chapter are abbreviated in such text citations:


                  (Cheek & Buss, 1981, p. 332)


                  (Shimamura, 1989, chap. 3)


            For electronic sources that do not provide page numbers, use the paragraph number, if available, preceded by the paragraph symbol or the abbreviation para. If neither paragraph nor page numbers are visible, cite the heading and the number of the paragraph following it to direct the reader to the location of the material.
