PS261 Chapter Notes - Chapter 7: Reinforcement, Devaluation, Hydromorphone
Document Summary
Motivation of response from 2 main perspectives: thorndike: associative structure of instrumental conditioning - associations, skinner: the response allocation approach limiting free flow of activities, pavlovian, molecular individualistic, molar long term, functional perspective. Associative structure of instrumental conditioning: thorndike(pavlov) molecular. Instrumental response (ir) happens in the context of specific environmental stimuli: text message sent. The s-r association and the law of effect. S-r: contextual association between stimuli and instrumental response: law and effect. Thorndike thought: once established, association is solely responsible for occurrence of instrumental. Behaviour (ib: basic impetus = expose to stimulus, assumed reinforcer was not important to the association, but rather was supplemental. Habits = 45% human behaviour: done with no meditation of goal, drugs = s-r. S-o: reinforcement of pairing stimuli with response outcome: mechanism of reward expectancy, can increase response when paired. Assumes 2 distinct types of learning: pavlovian.
