Professor Judge teaches in the Department of Psychology. He is also the Director of the Neuroscience Program and the Animal Behavior Program.

Educational Background

  • Ph.D. Psychology, University of Georgia

Research Interests

My general interests include aggression and conflict resolution behavior in nonhuman primate societies. My specific interests include reconciliation behavior after aggressive conflicts and the conflict management mechanisms primates use to reduce the risk of aggression in conflict-promoting situations, such as crowded conditions. I am also interested in the social cognitive processes that allow primates to exhibit complex patterns of conflict-management behavior. Ongoing projects include reconciliation behavior in hamadryas baboons and the cognitive abilities of capuchin monkeys (social cognition, numerosity, and tool use acquisition).
