Dissertation Title: Cognitive adaptations for calibrating welfare tradeoff motivations, with special reference to the emotion of shame
Universidad de Buenos Aires, Argentina, 2002, Anthropology
I am an evolutionary psychologist conducting research on the psychology of sociality. I combine methods, theories, and concepts drawn from the cognitive sciences and evolutionary biology to explore and map the evolved design of social emotions and their underlying motivational systems. I have multiple lines of cross-cultural evidence on shame, pride, compassion, and envy, and their roles in altruism, cooperation, social exclusion, and conflict. I am also working to map the system that regulates how much weight one individual places on the welfare of another. I conduct research on how these emotions and motivations regulate political and moral attitudes, and how they shape communication. The methods I use include experimental economic games, decision-making tasks, priming methods, cross-cultural and ethnographic data collection, large-scale representative surveys, and anthropometry.
