The Comparative Cognition Laboratory is a part of the Department of Psychological and Brain Sciences at The University of Iowa. Our research concerns the experimental investigation of cognitive processes in adaptive behavior, with an overarching interest in comparing cognition in humans and nonhuman animals. Specific research topics include: category learning, cognitive flexibility, and same-different conceptualization. The evidence that we collect constantly surprises us and forces us to view human cognition in a fresh light.
