PSY 101 Lecture Notes - Lecture 8: Operant Conditioning, Slot Machine, Reinforcement
Document Summary
Stimulus: any sensation that is within our perception (sights, sounds, smells) Conditioned: something acquired, taught, not neutral (eg. drooling at the sound of a bell) The unconditioned stimulus causes the unconditioned response (us -> ur) (tickled -> laugh) Neutral stimulus: causes no response (paper or desk) During acquisition ( to acquire)- repeatedly pair the neutral stimulus with the unconditioned stimulus to elicit an unconditioned response (ns + us -> ur) (bell + food = salvation) After conditioning- the ns becomes the conditioned stimulus (cs); the ur becomes the conditioned response (cr); the us is no longer necessary; and the cs now elicits the cr ( cs -> cr) (bell -> salvation) Large number of ns- us pairings (repetition) (12+) Extinction- subjects unlearn conditioning; done by repeatedly pairing cs with no other stimuli; eventually, cs no longer elicits cr. Cs -> cr; cs + nothing = cr; ns = nothing.
