THE SOCIAL COGNITION AND COOPERATION LAb
Kristin L. Leimgruber, Ph.D.
Principal Investigator, Lab Director
In the Social Cognition and Cooperation Lab, we strive to understand the psychology underlying human cooperation.
As humans, we cooperate more often, on a larger scale, and with more partners than any other being on Earth. Investigating the aspects of human behavior that set us apart from other species not only sheds light on the social cognitive abilities responsible for our uniqueness, but also provides a roadmap to promoting cooperation and generosity in our communities. In the Social Cognition and Cooperation Lab, we conduct studies with adults and children between the ages of 3 and 6 to gain insight into the psychology of cooperation over the course of the lifespan.
