Document Summary
Chaining : reinforcing each response with the opportunity to perform the next response. Example at first the rat learns to press a lever when it sees a light, but after accidentally hitting a bell nearby that turns the light on, the rat will learn to ring the bell. Operant generalization an operant response occurs to a new stimulus or situation that is similar to the original. Operant discrimination an operant response will occur to one stimulus, but not another. Every response of a particular type is reinforced. Ratio schedules are based on a certain percentage of reinforced responses. Reinforcement is given after a fixed number of responses (e. g. food after three pulls of lever) Reinforcement is given after a variable number of correct responses, all centered around an average (e. g. slot machine pays on average every 20 pulls) Interval schedules are based on a certain amount of time elapsing between reinforcements.
