Learning Chapter 9: Extinction of Conditioned Behavior

The susceptibility of responding to disruption by manipulations such a pre-session feeding, delivery of free food, or a change in the schedule of reinforcement.

The establishment of a memory in relatively permanent form so that is is available for retrieval a long time after original acquisition.

A schedule of reinforcement in which every occurrence of the instrumental response produces the reinforcer. Abbreviated CRF.

An explanation of the partial reinforcement extinction effect according to which extinction is slower after partial reinforcement than continuous reinforcement because the onset of extinction is more difficult to detect following partial reinforcement.

Reduction of a learned response that occurs because the conditioned stimulus is no longer paired with the unconditioned stimulus. Also, the procedure of repeatedly presenting a conditioned stimulus without the unconditioned stimulus.

Reduction of the instrumental response that occurs because the response is no longer followed by the reinforcer . Also, the procedure of no longer reinforcing the instrumental response.

A reduction of a learned response that occurs because of the passage of time, not because of particular experiences.

A theory of the partial reinforcement extinction effect, according to which extinction is retarded after partial reinforcement because the instrumental response becomes conditioned to the anticipation of frustrative nonreward.

A schedule of reinforcement in which only some of the occurrences of the instrumental response are reinforced. The instrumental response is reinforced occasionally, or intermittently.

Less persistence of instrumental behavior in extinction following extensive training with reinforcement (overtraining) than following only moderate levels of reinforcement training.

The effect is most prominent with continuous reinforcement.

Less persistance of instrumental behavior in extinction following training with a large reinforcer than following training with a small or moderate reinforcer. The effect is most prominate with continuous reinforcement.

The term used to describe greater persistence in instrumental responding in extinction after partial or intermittent reinforcement training than after continuous reinforcement training.

Recovery of excitatory responding to an extinguished stimulus produced by exposure to the unconditioned stimulus.

Recovery of excitatory responding to an extinguished stimulus produced by a shift away from contextual cues that were present during extinction.

A theory of the partial reinforcement extinction effect according to which extinction becomes conditioned to the memory of nonreward.
