Strangers With Benefits: Attraction to Outgroup Men Increases as Fertility Increases Across the Menstrual Cycle.

Research typically reveals that outgroups are regarded with disinterest at best and hatred and enmity at worst. Working from an evolutionary framework, we identify a unique pattern of outgroup attraction. The small-group lifestyle of pre-human ancestors plausibly limited access to genetically diverse mates.

Rejection sensitivity and adolescents' perceptions of romantic interactions.

Rejection sensitivity - the tendency to expect, perceive, and overreact to rejection by others - is linked with individuals' expectations that their romantic partners' behaviors have negative intent, even if, perhaps, such behaviors could be considered neutral when observed by another. The aim of the present study was to test this proposition, derived from rejection sensitivity theory, using a Video-Recall Procedure with adolescent couples in the US (N = 386 adolescents, 50% girls). We examined whether adolescents who were more sensitive to rejection perceived their romantic partners' behaviors as more conflictual than when viewed by trained, third-party observers.
