Looking deeper: Extradyadic behaviors,jealousy, and perceived unfaithfulness in hypothetical dating relationships

This report expands on past research dealing with extradyadic (ED) relations in dating relationships by examining behaviors beyond those of a strictly sexual or romantic nature that college-age men and women consider to be unfaithful. Undergraduates (N= 219) from a U.S. university rated a hypothetical partner's ED sexual behavior, sexual fantasies, romantic attachments, flirting, group, and dyadic social activities including a member of the other gender outside the primary dating relationship as a function of relationship stage. Men and women rated all the ED behaviors as jealousy provoking except group social activities, and rated all the behaviors as unfaithful except dyadic and group social activities. Women reported greater jealousy than did men in response to a hypothetical partner's sexual fantasies, romantic attachments, and flirting behavior. Women also reported a hypothetical partner's romantic attachments and flirting behavior as more unfaithful than did men. Results are discussed in terms of support for evolutionary theory and the need to acknowledge environmental factors in examining gender differences.
