PS261 Chapter Notes - Chapter 7: Demand Curve
Document Summary
Focus on how instrumental contingencies constrain an animal"s natural behavioural tendencies. The consummatory response theory: reinforcerss = special kinds of stimuli, consummatory response theory: many reinforcers like food + water elicited species-typical unconditional. Could strengthen an instrumental response responses i. e. licking, chewing, swallowing. The premack principle: had problem w consummatory response theory idea cons. Responses different from instrumental responses: according to premack the only thing that distinguishes consummatory responses from instrumental responses is the freq with which each of these would occur at baseline, predications: If animal gets to do h after doing l, l will increase relative to baseline. If animal gets to do l after doing h, h will not increase relative to baseline. It was the rats internal stat that determined which of the 2 responses were the reinforcing one. If opportunity to engage in specific response is restricted, this is the crucial ingredient in reinforcement. Important for instrumental conditioning because all procedures involve restricting4 a response.
