Document Summary

Operant conditioning: an increase or decrease in operant response as a function of the consequences that have followed the response. Positive reinforcer: any stimulus or even the increases the probability of an operant when presented. Chapter 4: reinforcement and extinction of operant behavior. Your car will not start, but when you jiggle the ignition key it fired right up. Based on past reinforcement, the operant(cid:357)jiggling the key(cid:357)is likely to be repeated the next time the car will not start. Operant behavior is emitted in the sense that it often occurs without an observable stimulus preceding it. This is in contrast to reflexive responses, which are elicited by a preceding stimulus. Discriminative stimulus (sd): an event or stimulus that precedes an operant and sets the occasion for operant behavior (antecedent stimulus) Change the probability that an operant will be emitted based on a history of differential reinforcement.
