title: Self-ratings of physical attractiveness in a competitive context: when males are more sensitive to self-perceptions than females.
abstract: The authors investigated sex differences in the ratings of physical attractiveness in a competitive context. Participants in an Ultimatum Game experiment offered to split a sum of money with their opponents who could either accept or reject the offers; subsequently, physical attractiveness ratings (both self-ratings and of the other) were obtained. The authors found that male participants rated themselves higher on physical attractiveness when facing male opponents than when facing female ones; there was no such difference for the female participants. Furthermore, male participants' self-ratings of physical attractiveness were higher than the ratings provided by their corresponding male opponents. The authors discuss these findings using the tenets of evolutionary psychology pertaining to as male intra-sexual rivalry in competitive contexts.
