Whereas the third, Humanistic, is more concerned with the uniqueness of the individual.

The behavioral perspective was first introduced through the studies of Russian physiologist, Ivan Pavlov. While studying digestion in dogs, Pavlov realized that the dogs had begun to associate certain sights or sounds with being fed (Davis and Palladino, p. 25).

This linking of two unrelated stimuli, to elicit a specific reflexive reaction or UCR (unconditioned response), is an example of a learned behavior.

This belief that only observable behavior should be the main focus of psychology was continued by the works of John B. Watson and B.F. Skinner. Watson believed that thinking, feeling, or consciousness should not be considered because it was not observable (Davis and Palladino, p. 195). They believed that learning was a permanent change in behavior caused only by environmental factors or consequences.
