Answer:

D. Cognition is unobservable.

Brief Explanations:

Behaviorists focus on observable behaviors. Cognition (mental processes like thoughts) is internal and not directly observable. So, behaviorists, who rely on observable data for their theories, are unlikely to include unobservable cognition as part of learning. Options A is incorrect as cognition was studied before behaviorism. Option B is wrong as behaviorist theories aren't disproven by cognition. Option C is false as cognition does affect behavior (e.g., a thought can lead to an action).
