The Cognitive and Social Development (CSD) Lab at Penn State, directed by Dr. Liben, houses research and teaching activities related to the way that individuals develop over their lifetimes. At the core, our projects are aimed at understanding how developmental progress comes about. We study progress in the cognitive arena — such as how people think about and represent their environments with maps, or in the social arena — such as how individuals develop identities and beliefs about social-group categories such as gender and race.
