Nobel price in 1904 • Notices “mental secretions” -anticipated responses of the animals becoming familiar to the setting. • Studied these “mental secretions” -they become what we know as “conditioned reflex”. Next Important concepts Pavlov brought us • The whole notion of conditioned reflex • Concepts of generalization, differentiation, excitation, inhibition, higher level conditioning • Concept of experimental neurosis Next Pavlov today? • Visit the Pavlov Institute of Physiology in Russia Next Who influenced Watson? • Reacts against Wundt and James -and their followers such as John Dewey • Infuenced by Loeb (tropisms) and Henry Donaldson (white rat neurology) -studied the myelinization of white rat nervous system & consequent changes in the complexity of their behavior. • Pavlov Next Watson’s main contributions • Official founder of behaviorism as an independent and valid approach to psychology • Is a radical behaviorist • Introduces the notion of conditioned emotional response (little Albert) • Three emotions: fear, rage, love -all emotional life built on those • Applies this to advertising Next B. F. Skinner Who influenced him? • Bertrand Russel’s (a British philosopher) discussion of J. B. Watson’s book on behaviorism. (Then, Watson himself) • H.G. Wells article on G. Bernard Shaw and Pavlov (Then Pavlov himself) Next What were Skinner’s main contributions? • Developed the Skinner box as a way to study operant behavior. • Important concepts: operant conditioning, reinforcement, contingencies of reinforcement, reinforcement schedules, discrimination learning, programmed instruction. • Developed the social implications of his theory. Next A Skinner page by undergraduate students • http://www.wabash.edu/depart/psych/Cours es/Psych97A/STUDENT%20PROJECTS/S kinner/hammondk/ Next Today’s Walden Two • Los Horcones, a Skinnerian utopian community existing today. • Twin Oaks, an intentional community with Skinnerian roots -more eclectic today, though it has maintained the Walden Two governance system and labor credit system.
