To write the correct reference citations in the body of the text for the given references, you need to follow the appropriate citation style, such as APA or MLA, as per your requirements. Here's an example using APA style:

A number of earlier studies have consistently found similar results (Hayes & Larson, 2006; Hayes, 2007; Hayes & Stone, 2009; Hayes & Thomas, 2011).

In this APA style citation format:
- When there are two authors, list both their last names in the same order as they appear in the original publication separated by an ampersand (&).
- When there are three or more authors, list the first author's last name followed by "et al." (meaning "and others") after a comma.

Please note that this is just an example for APA style. If you require a different citation style, the format may vary.
