Strategies for In-Text Citation
You may word your in-text citation in several different ways to maximize the effectiveness of your writing. The most straightforward method is to include the author's (or authors') last name and the page number(s) following the quotation, idea, or fact you are citing.
There is not a strong correlation between a high GPA and students who began reading at an early age (Kahneman & Klein, 2009).
You may also refer to the author's name in the text of your paper. In this case, cite the date in parentheses following the author's name.
Kahneman & Klein (2009) found that there is not a strong correlation between a high GPA and early readers.
If you are using a direct quotation, include the page number where the quotation can be found.
"The correlation between early reading and graduating GPA is not high" (Kahneman & Klein, 2009, p. 522).

One to Two Authors: Cite each author every time the reference occurs.
The Publication Manual of the American Psychological Association was first published in 1929 (American Psychological Association, 2010).
Three to Five Authors: Cite each author the first time the reference occurs. In subsequent references, cite only the first author followed by "et al." (meaning "and others") and the date.
Example - First Occurence:
A study by Nittrouer, Lowenstein, and Packer (2009) compared the abilities of native English-speaking children and adults.
Example - Subsequent Occurences:
The study found that English-speaking adults performed best (Nittrouer et al., 2009).
Six or More Authors: Cite only the name of the first author followed by "et al." and the date.
