To prevent a partner's infidelity and relationship defection, men perform mate retention behaviors. Some of these mate retention behaviors are high-risk because they decrease the likelihood of infidelity while potentially increasing the likelihood of relationship defection. Although previous research has indicated that mate value may be related to mate retention generally, research has not addressed these cost-inflicting mate retention behaviors specifically. The current research examines the relationship between men's and women's mate values and men's use of partner-directed insults - a specific type of cost-inflicting mate retention behavior. The results from a sample of 158 women indicate that although men's and women's mate values predict men's partner-directed insults, men's mate value is a better predictor than is women's mate value. Women who report that their partners have lower mate value also report that their partners insult them more frequently than women who report that their partners have higher mate value. / by Emily J.

Evolutionary psychology offers a framework for investigating the design of evolved information-processing mechanisms that motivate costly behaviors such as men's partner-directed violence. The current research investigated predictors of and individual differences in men's intimate- partner-directed violence from an evolutionary psychological perspective. The problem of paternity uncertainty is hypothesized to have selected for the emotion of male sexual jealousy, which in turn motivates men's nonviolent and violent mate-retention behaviors. Study 1 documented a hierarchy of behaviors initiated with men's suspicions of partner infidelity leading to men's engagement in frequent non-violent mate-retention behaviors, ending in men's partner-directed violence. Study 2 documented an interaction between men's personality traits and the context of perceived partner infidelity risk to predict men's perpetration of violence. Finally, Study 3 extended Studies 1 and 2 by building a causal cascade model that captures the hierarchy of adaptive behaviors in order of: (1) men's childhood experiences with their parents' parental effort, (2) men's adaptive life history strategies and behavioral self-regulation, (3) men's perceptions of partner infidelity risk, and (4) men's non-violent mate retention behaviors, conclusively predicting men's perpetration of violence in intimate relationships. / by Farnaz Kaighobadi. / Thesis (Ph.D.)--Florida Atlantic University, 2011. / Includes bibliography. / Electronic reproduction.
