Document Summary
Using successive approximations to reach target behaviour. Rewarding remotely related behaviour, stricter criterion over time. Continuous- reward behaviour every time it occurs. Partial- reward the behaviour only sometimes when it occurs. Partial reinforcement is preferred; partial reinforcement extinction; superstition stems from this: ratio schedules. Provide reward after a number of responses. Fixed ratio- getting a reward after a fixed number of responses. Variable ratio- reward varies after number of responses. Provide reward after a period of time (only if the response has occurred) Fixed interval- amount of time passed stays fixed. Variable interval- amount of time passed varied. Fixed interval example- a biweekly pay schedule. Post reinforcement pause- occurs in a fixed interval; after reward people/animals take a short break before continuing the task. Scalloping effect- reward is followed by a long break; responding increases. Latent learning: learning that occurs that isn"t evident when it happens, evidence/example. One trial per day; dv: # of errors.
