Which statement accurately describes the role of the environment in behavior therapy's success?

• A. It is influenced by the environment; success depends on control of environmental factors
• B. It is driven only by internal motivation
• C. It relies on dream content
• D. It ignores external factors

Answer: (D)

Behavior is understood as a product of environmental contingencies, and success in behavior therapy comes from changing those surroundings to shape what a person does. By arranging reinforcement for desired behaviors, removing reinforcers for undesired ones, and using techniques like modeling, exposure, or skill training within a structured environment, therapists influence behavior directly through external factors. That focus on observable actions and the external setup is why the environment’s control over contingencies is central to the approach. Concepts like internal motivation, dream content, or ignoring external factors don’t fit this framework, since they either emphasize internal states or disregard the environmental triggers and consequences that behavior therapy targets.
