Although robust sex differences are abundant in men and women’s mating psychology, there is a considerable degree of overlap between the two as well. In an effort to understand where and when this overlap exists, the current study provides an exploration of within-sex variation in women’s mate preferences. We hypothesized that women’s intelligence, given an environment where women can use that intelligence to attain educational and career opportunities, would be: (1) positively related to their willingness to engage in short-term sexual (...) relationships, (2) negatively related to their desire for qualities in a partner that indicated wealth and status, and (3) negatively related to their endorsement of traditional gender roles in romantic relationships. These predictions were supported. Results suggest that intelligence may be one important individual difference influencing women’s mate preferences. (shrink)

Several hypotheses on the form and function of sex differences in social behaviors were tested. The results suggest that friendship preferences in both sexes can be understood in terms of perceived reciprocity potential—capacity and willingness to engage in a mutually beneficial relationship. Divergent social styles may in turn reflect trade-offs between behaviors selected to maintain large, functional coalitions in men and intimate, secure relationships in women. The findings are interpreted from a broad socio-relational framework of the types of behaviors that (...) facilitate selective advertisement and investment of reciprocity potential across individuals and within groups of men and women.

Despite a staggering body of research demonstrating sex differences in expressed emotion, very few theoretical models (evolutionary or non-evolutionary) offer a critical examination of the adaptive nature of such differences. From the perspective of a socio-relational framework, emotive behaviors evolved to promote the attraction and aversion of different types of relationships by advertising the two most parsimonious properties ofreciprocity potential, or perceived attractiveness as a prospective social partner. These are the individual's (a)perceived capacityor ability to provide expedient resources, or to (...) inflict immediate harm onto others, and their (b)perceived trustworthinessor probability of actually reciprocating altruism (Vigil 2007). Depending on the unique social demands and relational constraints that each sex evolved, individuals should be sensitive to advertise “capacity” and “trustworthiness” cues through selective displays of dominant versus submissive and masculine versus feminine emotive behaviors, respectively. In this article, I introduce the basic theoretical assumptions and hypotheses of the framework, and show how the models provide a solid scaffold with which to begin to interpret common sex differences in the emotional development literature. I conclude by describing how the framework can be used to predict condition-based and situation-based variation in affect and other forms of expressive behaviors. (shrink)
