In this lecture from Yale's Everyday Parenting: The ABCs of Child Rearing, Dr. Alan Kazdin introduces simulation, a technique that helps children practice desired behaviors by turning them into fun, pretend games or role-play situations rather than only addressing behavior in the heat of the moment. Kazdin explains how rehearsing calmer responses in a low-stakes, playful setting can reduce the frequency and intensity of tantrums when real triggers arise. The lecture provides practical guidance on setting up simulation exercises at home and pairing them with the reinforcement techniques covered earlier in the course. It continues the ABCs of Child Rearing sequence, adding simulation to antecedents and shaping as tools parents can use to proactively support better behavior.
