How Willing Are You to Accept Sexual Requests from Slightly Unattractive to Exceptionally Attractive Imagined Requestors?

 In their classic study of differences in mating strategies, Clark and Hatfield (1989, Journal of Psychology and Human Sexuality, 2, 39–54) found that men and women demonstrated a striking difference in interest in casual sex. The current study examined the role of an imagined requestor’s physical attractiveness (slightly unattractive, moderately attractive, and exceptionally attractive) on men’s and women’s willingness to accept three different requests (go out, come to apartment, go to bed) as reflected in answers to a questionnaire. We tested two hypotheses with a sample of 427 men and 443 women from three countries. Hypothesis 1 states that men, relative to women, will demonstrate a greater willingness to accept the “come to apartment” and “go to bed” requests but not the “go out” request for all three levels of requestor attractiveness. This  hypothesis reflects Clark and Hatfield’s main findings. Hypothesis 2 states that the physical attractiveness of a potential partner will have a greater effect on women’s than on men’s willingness to accept all three requests, and particularly for the explicit request for casual sex. The results partially supported Hypothesis 1 and fully supported Hypothesis 2. The discussion highlights limitations of the current research and presents directions for future research.

 Rape is a traumatic event with severe consequences for women. Therefore, women may have evolved
psychological mechanisms that motivate them to avoid circumstances linked with rape. We present the development and initial psychometric assessment of an inventory designed to assess women’s rape avoidance behaviors. In Study 1 (N = 99), we conducted an act nomination procedure to identify specific behaviors for inclusion in a preliminary rape avoidance inventory. In Study 2 (N = 144), we secured performance reports for the behaviors assessed by the inventory. We present the results of principal components analyses and the construction of the rape avoidance inventory (RAI). We identified four components of women’s rape avoidance behaviors as assessed by the RAI: avoid strange men, avoid appearing sexually receptive, avoid being alone, and awareness of surroundings/defensive preparedness. We demonstrate that, as predicted, performance of rape avoidance behaviors is negatively associated with a measure of interest in and pursuit of short-term sex. We conclude that the RAI is a useful tool for future research on rape avoidance and rape prevention
