Lattal, Kennon – Facets of Operant Extinction – Operant extinction is a cluster of procedures, all of which reduce the targeted response often while generating other responses. Procedures for reducing operant responses that have been laleled extinction include the removal of the reinforcer, removal of the response-reinforcer relation, and rendering ineffective the reinforcer used to establish the responses. These different procedures are differentially effective in both eliminating the targeted response and in generating other responses. These generative effects include operant response bursts, spontaneous recovery, response induction, generalization, and recurrence phenomena such as reinstatement and resurgence. This tutorial reviews the varied effects of extinction on an operant behavior; compares such effects to those of other procedures such as reinforcing other responses, punishment, satiation; and critiques historical and contemporary research on those topics.
