Extinction
| Question | Answer |
|---|---|
| extinction | withholding reinforcement for a previously reinforced response |
| effects of extinction | decreases in the behavior |
| characteristics of extinction | extinction burst operant variability emotional responses |
| extinction burst | the target behavior may increase in frequency, duration, or magnitude at first when the reinforcer no longer follows it |
| operant variability | the topography (form) of the behavior may change when the original form is no longer reinforced |
| emotional responses | emotional behavior such as attacking and crying may occur when the target behavior is no longer followed by the reinforcer |
| spontaneous recovery | the behavior occurs again sometime later after it had been eliminated with extinction a phenomenon, not a characteristic of extinction |
| variations of extinction | effect: the response has decreased/extinguished due to no longer producing a reinforcer procedure: implementation of the technique, withholding the reinforcer |
| the partial reinforcer effect | behavior is less resistant to extinction following continuous reinforcement compared to intermittent reinforcement. |
| using schedules to teach behavior | continuous reinforcement (CRF) schedule thinning |
| schedule thinning | gradually change the schedule from CSF to an intermittent schedule, improves resistance to extinction, if you move to quickly, you can produce ratio strain (extinction) |
| extinction prerequisite | function (cause) of behavior |
| functional assessments | identify the reinforcer of a given bx control reinforcer (1) deliver it contingent on adaptive behavior (2) challenging when? what function? |
| procedural variations of extinction | extinction of positively reinforced behavior extinction of negatively reinforced behavior |
| extinction of positively reinforced behavior | the positive reinforcer is no longer delivered following the behavior |
| extinction of negatively reinforced behavior | the aversive stimulus is no longer removed following the behavior |
| behavior maintained by positive reinforcement (sr+) | do not present the positive reinforcement if absent discontinue the positive reinforcement if present |
| behavior maintained by negative reinforcement (sr-) | do not terminate ongoing stimulation do not relay presentation of stimulation |
| behavior maintained by automatic SR | modify source of stimulation so R does not produce it modify some feature of the response so it does not produce reinforcement |
| factors that facilitate extinction | historical factors EXT-related factors other procedures combined with EXT |
| basic process of the PRE | discrimination contact with the contingencies |
| advantages of extinction | simplest, most direct method of behavior reduction plays a major role in discrimination training |
| disadvantages of extinction | some Sr are difficult to identify or eliminate possibly slow acting potential side effects does not directly produce an alternative behavior |
