It is argued that, while men may be intrasexually more competitive than women, to attract potential mates, men will, more than women, associate with same-sex friends who are attractive to the opposite sex. Therefore, more than women, men will choose more physically attractive and dominant companions in a mating context than in a neutral context. In Study 1 among 262 participants a mating scenario (going to a party) and a neutral scenario (seeing a movie) were developed, and it was shown that the mating scenario did indeed induce more a mating context than the neutral scenario. In Study 2 among 167 participants the hypotheses were tested by examining the preferences for a companion in both scenarios. The findings from Study 2 supported the predictions. In response to the mating as compared to the neutral scenario, men, but not women, found the attractiveness of a companion more important, preferred a more socially dominant companion, and found the social dominance of a companion more important. Men as well as women preferred in general companions who were less attractive than themselves, but preferred a more attractive companion in a mating than in a neutral context. The effects for social dominance were in general more pronounced among individuals high in sociosexual orientation (SOI). To conclude especially mens' attitude towards same sex others in a mating context may be driven by the desire to associate, rather than to compete, with same-sex others who are attractive to the opposite sex.
