Which theory operates on the "stimulus-response principle", meaning all behaviors are caused by external stimuli?

• A. Psychoanalytic theory
• B. Behaviorist theory
• C. Humanistic theory
• D. Cognitive theory

Answer: (B)

The stimulus-response principle is the core idea of behaviorist theory. It holds that observable behavior is triggered directly by external stimuli in the environment, and learned through interactions with those stimuli and the consequences that follow. Classic conditioning (associating a neutral stimulus with a meaningful one) and operant conditioning (behavior shaped by reinforcement or punishment) show how external factors shape responses. This emphasis on outward, measurable behavior and environmental influence distinguishes behaviorism from other approaches that focus on internal thoughts, unconscious motives, or personal growth.
