Neo-behaviorism

This field agrees with the behaviorist stance that overt behavior is what should be studied, but felt that speculation about abstract concepts was an acceptable method as long as the speculation is investigated after operationally defining terms and forming testable hypotheses.

Edward Chace Tolman 1886-1959

Chose to study purposive behavior in place of Watson’s ‘twitchism’

Used rats to avoid introspection

Cognitive events are intervening variables between environmental events and behavior

Learning is latent until it is needed (3 groups of rats in a maze)

 

Clark Leonard Hull 1884-1952

Hypothetico-Deductive Theory à a series of self-correcting claims which predict empirical relationships

Drive reduction theory of reinforcement à any behavior that reduces a drive is reinforced

Hull’s theory explains little outside of the laboratory

 

Edwin Ray Guthrie 1886-1959

The law of contiguity is the one law of learning (stimuli accompanied by a response will become associated with that response)

One-trial learning à stimuli are linked with responses after the first presentation

 

Burrhus Frederic Skinner 1904-1990

Greatly influenced by Bacon

Mental events are simply responses to physiological events

Studied operant behavior à behavior which is controlled by its outcome

Skinner’s DV was response rate; anything that can change response rate is a reinforcer

Encouraged reinforcement rather than punishment
