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)

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.

According to the research on the influence of resources on mate selection, the amount of financial resources affects an individual’s choice of "luxuries" and "necessities" among mate selection cues, while the amount of time resources affects cue diversity. However, for a long time, researchers only paid attention to the impact of financial resources and ignored the role of time resources. Therefore, this paper draws lessons from the relevant research on the influence of time on decision-making and proposes to study mate (...) selection from the perspective of decision-making. Additionally, current research concerning the influence of resources on the choice of a spouse focuses more on results and neglects to examine the process. Therefore, based on the relevant theories, this paper makes several theoretical assumptions regarding the influence mechanism of resource availability on mate choice decisions, gender differences and the actor-partner effect.
