Developed by the American Psychological Association, this style is most widely used for research papers in psychology and social sciences.
Citing a source in this style consists of two parts:
See How to Format In-Text Citations, How to Format the Reference List, and the Examples in the left navigation for details.
For more detailed information see Publication Manual sections 6.11-6.21.
An in-text citation provides your reader with two pieces of information:
Myrick (2015) examined the guilty pleasures of watching Internet cats.
Viewing online cats could help to regulate emotions, much like pet therapy in real life (Myrick, 2015).
(Hinsch & Sheldon, 2013)... Hinsch and Sheldon (2016) found....
(Nabi, Finnerty, Domschke, & Hull, 2006) ..... Nabi et al. (2006) demonstrated ....
(J. Moher, 2012 )
(M. Moher & Feigenson, 2013)
Children with bipolar disorder are treated in similar ways as adults (National Institute of Mental Health, 2015).
Polls show that black workers approve of labors unions more than white workers ("Black Workers Matter," 2016).
For more detailed information see Publication Manual sections 6.03-6.10.
When paraphrasing, APA style does not require page numbers in the in-text citation. However, authors are encouraged to include page numbers if it will help the reader locate the relevant information in longer texts. Consult with your professor regarding the need for page numbers for paraphrased information.
For direct quotations, the author, year and page number must be included. The page number can be given in parentheses at the end of the exact quotation or incorporated into the in-text citation.
Newman (1994) concluded "sibling conflict is so common that its occurrence is taken for granted" (p. 123).
Such findings have prompted one researcher to conclude, “Sibling conflict is so common that its occurrence is taken for granted” (Newman, 1994, p. 123).
For direct quotations from sources without page numbers, use paragraph numbers, if visibly numbered in the document. Otherwise, use the heading name and count the number of paragraphs after the heading to the paragraph containing the quotation.
(Smith, 2016, para. 1)
(Lee 2015, Discussion section, para. 4)
The reference list provides the full details on the sources you used in the research for your paper.
Each entry should include the following reference components:
See the examples in the left navigation for the required elements for each type of source. Continue reading below for details on formatting each reference component and ordering the reference list.
