This document discusses modeling as a psychotherapy technique based on observational learning. It summarizes that modeling involves demonstrating desired behaviors for a client to imitate. The key processes of observational learning are attentional processes, retention processes, motor production processes, and motivational processes. Modeling can be presented live, symbolically through video/film, or through covert imagery. Imitation and vicarious learning are forms of modeling that can result in acquisition, strengthening, or weakening of behaviors. Factors like successful consequences, similarity between model and observer, behavior complexity, attention, context, repetition, and feedback impact modeling effectiveness.
