Behaviorism

I started to refresh my mind in theory of motivation. I will start with topic Behaviorism originated by Pavlov, BF Skinner and John Watson.


Behaviorism
Summary: Behaviorism is a worldview that operates on a principle of “stimulus-response.” All behavior caused by external stimuli (operant conditioning). All behavior can be explained without the need to consider internal mental states or consciousness.
Originators and important contributors: John B. Watson, Ivan Pavlov, B.F. Skinner, E. L. Thorndike (connectionism), Bandura, Tolman (moving toward cognitivism)
Keywords: Classical conditioning (Pavlov), Operant conditioning (Skinner), Stimulus-response (S-R)


Behaviorism is a worldview that assumes a learner is essentially passive, responding to environmental stimuli. The learner starts off as a clean slate (i.e. tabula rasa) and behavior is shaped through positive reinforcement or negative reinforcement. Both positive reinforcement and negative reinforcement increase the probability that the antecedent behavior will happen again. In contrast, punishment (both positive and negative) decreases the likelihood that the antecedent behavior will happen again. Positive indicates the application of a stimulus; Negative indicates the withholding of a stimulus. Learning is therefore defined as a change in behavior in the learner. Lots of (early) behaviorist work was done with animals (e.g. Pavlov’s dogs) and generalized to humans.
