Since Kinsey and his colleagues (Kinsey, Pomeroy, Martin, & Gebhard, 1948; 1953) first began to empirically examine human sexual behavior researchers have found that heterosexual men tend to report having had more sexual partners than heterosexual women. The purpose of the present study was to explore this phenomena using a within subject design. Participants were 124 undergraduate women who completed a packet of surveys on sensitive topics, such as sexuality, and body image, in two conditions: Anonymity Threat Condition: Participants were led to believe that the principle investigator would come in a view their responses while completing the surveys and Bogus Pipeline: Participants were led to believe that they were `hooked-up' to a lie detector. Results found within as well as between subject effects for measures of social desirability and one sexual attitude measure. However, these results did not generalize to the body image measures or sexual behavior questions. / Department of Psychological Science
