In its early years, critics held that the empiricism of cognitive psychology was incompatible with its acceptance of internal mental states.

The school of thought arising from this approach is known as cognitivism. Cognitive psychology has also influenced the area of Cognitive Behavioral Therapy(CBT) where the combination of cognitive and behavioral psychology are used to treat a patient.

Also emphasizing that it is a "point of view" that postulates the mind as having a certain conceptual structure. Neisser's point of view endows the discipline with a scope beyond high-level concepts such as "reasoning" that other works often espouse as defining psychology. Neisser's definition of "cognition" illustrates this well: The term "cognition" refers...
