In this Yale lecture from Everyday Parenting: The ABCs of Child Rearing, Dr. Alan Kazdin explains modeling, learning by example, as a powerful way parents can shape their children's behavior. Kazdin distinguishes intentional, systematic modeling from the everyday, accidental modeling parents do without realizing it, and shows how deliberately demonstrating a desired behavior can be more effective than instruction alone. The lecture offers practical guidance on how to model behavior clearly and consistently so children are more likely to imitate it. It builds on the course's earlier lessons on antecedents, shaping, and simulation, adding modeling as another evidence-based technique in Kazdin's behavioral toolkit for everyday parenting.
