PSYB45H3 Chapter 12: Chapter 12 Summary
Document Summary
Drl schedule in which reinforcer presented only if particular response occurs at low rate. Limited-responding drl specifies max. responses during interval (if some behaviour tolerable) Spaced-responding drl specific behaviour not occur during interval, after interval instance of behaviour required for reinforcement. Dr of zero responding (dro) reinforcer presented only if response doesn"t occur during interval aka differential reinforcement of other responding (reinforcer for some other behaviour) Inappropriate classroom behaviour, thumbsucking, skinpicking, motor and vocal tics, self-injurious behaviour. When behaviour should be eliminated and there is no danger that procedure will lead to reinforcement of undesirable alternative behaviour. Dro size gradually increased (until behaviour rare or mini. reinforcement needed) Dr of incompatible behaviour (dri) withholding reinforcers for target and reinforcing incompatible response (incompatible: the two can"t occur together, must choose one or other) Choose appropriate behaviour to strengthen that is incompatible. Dr of alternative behaviour (dra) extinction of problem behaviour combined with reinforcing a topographically dissimilar behaviour (not necessarily incomparible)
