Welcome!

Welcome to the Emotion Development Lab (EDL) at the Pennsylvania State University. EDL was established in 2001 under the direction of Dr. Kristin Buss at the University of Missouri. The lab is currently located at Penn State's University Park campus and is affiliated with the Department of Psychology's developmental and child clinical training programs (see the department web page for more information). Our research involves understanding the complex systems involved in the development of emotions, temperament, and personality in infants, toddlers, and young children. We are interested in understanding early emerging individual differences in social-emotional behaviors and the consequent developmental trajectories of different types of behavior.
