Which term in the behavior definition includes covert mental events such as thinking and imagining?

• A. Behavior
• B. Response
• C. Action
• D. Cognition

Answer: (A)

Covert mental events like thinking and imagining are included in behavior because, in behavior analysis, behavior is the broad umbrella for what a person does, encompassing both observable actions and private events. This view treats thoughts and mental processes as part of the person’s overall activity, even though we measure mainly what can be observed. So the term that encompasses those covert events within the behavior definition is behavior. A single observable instance, such as a specific response, is just one example of behavior. An action is a movement or act, but doesn’t capture the broader range including private events. Cognition refers specifically to thinking processes themselves, not the general label used to describe all of a person’s activities.
