Which term is a form of behaviorism that seeks to understand all human behavior including private events?

• A. METHODOLOGICAL BEHAVIORISM
• B. MENTALISM
• C. RADICAL BEHAVIORISM
• D. IMITATION

Answer: (A)

Radical behaviorism includes private events—thoughts, feelings, and internal sensations—as part of the scope of behavior to be understood and explained. B.F. Skinner argued that these private events, while not directly observable by others, are still behaviors that can be analyzed in terms of their functional relationships with environmental contingencies, just like public actions. This expansion allows a single, cohesive account of all human behavior, not just what can be seen.

Methodological behaviorism, in contrast, focuses only on publicly observable behavior and does not treat private events as subject to behavioral analysis. Mentalism relies on internal mental states to explain behavior rather than a behavior-analytic framework. Imitation is a specific process studied within behavior analysis, but it does not characterize a form of behaviorism that claims to explain all private and public behavior.

Therefore, the term that seeks to understand all human behavior, including private events, is radical behaviorism.
