Classical vs. Operant Conditioning

Classical and Operant Conditioning, discovered by Ivan Pavlov and B.F. Skinner, respectively, are similar as well as different in many ways. Classical Conditioning is a form of learning where why someone responds in a certain way to something is studied. In Operant Conditioning, however, studies how different stimuli affect a behavior. Classical Conditioning looks into why someone reacts to something, but not how it changes along with different reactions to the behavior, like Operant Conditioning does. Classical Conditioning was also discovered before Operant Conditioning, so B.F. Skinner had the possibilty to read about Pavlov's theory before developing his own.
