Research Interests:

I am interested in how group-living individuals regulate their social relationships, in particular how they manage aggressive conflict within the context of their various relationships. Much of my research has been carried out with non-human primates however, I am also researching the development of conflict management mechanisms in children and the underlying cognitive mechanisms associated with conflict mitigation and negotiation.

In addition to how primates manage their aggressive conflicts, I have explored how individuals maintain their cooperative relationships through reciprocation and interchange of valuable social services. The complex cognitive skills that may underlie decisions regarding interchange can be evaluated by examining the patterning and timing of interchange.

My research in humans has included investiagtions of mate preferences. I am interested in the adaptive nature of human mate preferences and their plasticity and flexibility in today’s societies. My research has involved projects examining the influence of feminist attitudes on traditional mate preferences and the manipulation of female clothing in response to increased mate competition.
