Document Summary

Extinction (nonreinforcement of a previously reinforced response, resulting in a decrease in strength of that response) (beh. no longer occurs, baseline level: both a procedure (nonreinforcement) & a process (resulting decrease in strength) Resistance to extinction (extent that responding persists after an extinction procedure has started: fast disappearing response=low resistance to extinction, can be affected by: Partial reinforcement effect (pre) (beh. that"s been maintained on a partial schedule will extinguish slower than beh. on continuous schedule) History of reinforcement (more reinforcers for beh. Amount of deprivation (more deprivation = stronger resistance) Stimulus control (presence of a discriminative stimulus reliably affects the prob of the beh. ) Stimulus generalization (operant response to be emitted in the presence of a stimulus that is similar to a sd) Generalization gradient (image of strength of responding in the presence of stimuli that are similar to the sd and vary along a continuum: steep gradient=less generalization.
