Impulsivity

Dr. Stevens is an Assistant Professor of Psychology at The University of Nebraska, Lincoln. He received his Ph.D. in Ecology, Evolution, and Behavior at the University of Minnesota in 2002. He then received a Ruth L. Kirschstein National Research Service Award to complete a post-doctoral fellowship in the Psychology Department at Harvard University. From 2006-2011, he was a research scientist in the Center for Adaptive Behavior and Cognition at the Max Planck Institute for Human Development in Berlin, Germany. In addition to being a faculty member in the Department of Psychology, he is also a core faculty member of the Center for Brain, Biology and Behavior. Dr. Stevens' research integrates cognitive and evolutionary perspectives to study decision making in humans and other animals. He uses theoretical, experimental, and comparative methods to model and empirically investigate the cognitive processes organisms use when making decisions. He is currently editor-in-chief of Frontiers in Comparative Psychology.
