B.F. Skinner is a name associated with behaviorism, a term referring to a form of conditioning theory such as was developed by Pavlov, Watson, and then Skinner. In considering how human actions and attitudes are formed, behaviorists emphasize the processes by which behavior is formed from the external environment. The classical conditioning paradigm was set forth by Pavlov, who noted that the introduction of a stimulus conditioned certain behavior. Pavlov's approach to conditioning was restricted to a certain range of innate responses. Watson thought we should study only overt behavior and was especially interested in the conditioning of emotions. He saw only three emotions as innate--fear, rage, and love. Watson offered an analysis of conditioning and a means of deconditioning certain behaviors, notably fear. Watson helped make classical conditioning a cornerstone of psychological theory. Skinner offered operant conditioning, a model of behavior based on observation. He was concerned with how environments control behavior and thought that operant behavior rather than respondent behavior played a greater role in life. Operant conditioning became a means of behavior modification. skinner's approach has been highly controversial, with supporters and critics arguing over the meaning of his behaviorist approach and its consequences, especially for the idea of free will. Skinner himself has entered the fray to answer his critics.
Skinner discusses one of the controversial aspects of his theory as he notes that having analyzed how behavior is shaped, he turned to issues of control, meaning how these theories could be applied deliberately to shape behavior. Skinner wrote about his views on the subject of freedom and determinism, he says, and then was bitterly attacked as playing down the role of the individual:
The fact is, I accept the ends of a democratic philosophy, but I disagree with the means which are at the moment ...
