I. In-Text Citations
A. Citing Direct Quotations
- Direct quotes include the author’s last name, followed by the date of publication and the page number. For example: "In 2006, a study showed that robots can learn patterns of behavior from movements and emotional signals around them” (Pope, 2007, p. 27).
- If the author’s name is mentioned in a signal phrase, the name should be followed by the year of the publication to which the citation belongs. The citation should be followed by its page number. For example: Pope (2007) mentioned that “robots can learn patterns of behavior from
movements and emotional signals around them” (p. 27).
B. Citing Paraphrased or Summarized Information
When citing paraphrased or summarized information from a source, only the author and year of publication are necessary, although the page number may be added optionally. For example:
Pope (2007) mentioned that robots can learn to respond emotionally.
In APA style, the Reference Page lists only those sources directly cited in the text of the paper rather than all background sources. The page should be labeled References and appear at the end of the paper. After the first line of each reference entry, the rest of the reference should be indented five to seven spaces from the left. Reference entries should appear in alphabetical order according to the last name of the first author of each publication. Two works by the same author should appear in the chronological order in which they were published. Although the following examples are single-spaced, the Reference Page should be double-spaced, including individual entries.

Single Author (last name first, followed by initials):

A page header should appear in the upper right-hand corner of each page, starting with the title page. Include a 1-2 word summary title of the paper, followed by five spaces, and then the page number.
