The aim of this study was to explore how people's sexual history affects their attractiveness. Using an Internet survey, 188 participants rated their willingness to engage in a relationship with a hypothetical individual with a specified number of past sexual partners, ranging from 0 to 60+. The effect of past partner number was very large. Average willingness ratings initially rose as past par...

We used data from the National Survey on Violence against Women in France carried out in 2000 on a representative sample of 6,970 women to compare the social characteristics of women who had sex with women (WSW) and women who had sex only with men (WSM). The WSW were more likely to be of a high socio-economic level and living in large cities. They were more frequently unmarried, without childre...

Effect of sexual dimorphism and averageness on the judgment of facial attractiveness was investigated. Participants (n=114) rated attractiveness of 96 facial photographs with neutral expressions. Principal component analyses were conducted on 80 facial feature points standardized via the generalized Procrustes method. Local regression analysis was used to obtain the distribution of attractivene...

Sexual selection theory and parental investment theory have guided much of the evolutionary psychological research on human mating. Based on these theories, researchers have predicted and found sex differences in mating preferences and behaviors. Men generally prefer that their long-term partners are youthful and physically attractive. Women generally prefer that their long-term partners have e...

Because sexual assault is often defined in terms of nonconsent, many prevention efforts focus on promoting the clear communication of consent as a mechanism to reduce assault. Yet little research has specifically examined how sexual consent is being conceptualized by heterosexual college students. In this study, 185 Midwestern U.S. college students provided responses to open-ended questions add...

Previous researchers have documented that the color red enhances one's sexual attraction to the opposite sex. The current study further examined the moderating role of sexual dimorphism in red effects. The results indicated that red enhanced men's sexual attraction to women with more feminine facial characteristics but had no effect on ratings of perceived general attractiveness. Red clothing a...

and other publications on women’s health and fitness in relation to their serving in the military services, this issue never seems to be laid to rest. Australian Defence Force policy supports the employment of women in traditionally male-dominated, previously exempted areas of military service, with the exception of direct combat.1 In spite of this, many of the obstructive arguments still exist...

The impact of types of social connectedness-family, other adult, and school-on suicide ideation and attempts among all youth, the relative impact of each type, and effect modification by sexual orientation was assessed. Data were from the 2007-2009 Milwaukee Youth Risk Behavior Surveys. Multivariable logistic regression analyses calculated the risk of suicide ideation and attempts by sexual ori...

Few sex differences in regret or counterfactual thinking are evident in past research. The authors discovered a sex difference in regret that is both domain-specific (i.e., unique to romantic relationships) and interpretable within a convergence of theories of evolution and regulatory focus. Three studies showed that within romantic relationships, men emphasize regrets of inaction over action (...
