The Developmental Psychopathology Lab conducts research to understand how children develop behavior problems as well as positive adjustment. We have been particularly interested in externalizing behavior problems, such as aggressive, disruptive, and noncompliant behavior. We focus on the development of self-regulation skills and the consequences of children’s self-regulation skills (or deficits) for their school readiness. The goal of our lab is to improve understanding about how children develop behavior problems from a very early age (3–7 years).
