The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
This same external stimulus can also lead to an increased response of a conditioned reaction, called disinhibition, when introduced after experimental extinction (when the conditioned response process is independent of the conditioned stimulus). [3] During extinction, the subject has been unconditioned as to not show the conditioned response ...
Counterconditioning is very similar to extinction seen in classical conditioning. It is the process of getting rid of an unwanted response. But in counterconditioning, the unwanted response does not just disappear, it is replaced by a new, wanted response. "The conditioned stimulus is presented with the unconditioned stimulus". [3]
Extinction of a previously conditioned inhibitor The RW model predicts that repeated presentation of a conditioned inhibitor alone (a CS with negative associative strength) results in extinction of this stimulus (a decline of its negative associative value). This is a false prediction.
This theory is given further support by Gorea and Sagi's inducing of extinction-like events in undamaged patients when presented with simultaneous stimuli of different intensities, with the lower intensity stimulus being extinguished by the mere presence of the high intensity stimulus. [7] Extinction frequency may also be affected by reporting ...
Spontaneous recovery is associated with the learning process called classical conditioning, in which an organism learns to associate a neutral stimulus with a stimulus which produces an unconditioned response, such that the previously neutral stimulus comes to produce its own response, which is usually similar to that produced by the unconditioned stimulus.
However, the stimulus–reinforcer relation was enhanced in the red context because the overall rate of food presentation was greater. Consistent with behavioral momentum theory, resistance to presession feeding (satiation) and discontinuing reinforcement in both contexts (extinction) was greater in the red context.
Extinction is the absence of a rewarding stimulus, which weakens behavior. Writing in 1981, Skinner pointed out that Darwinian natural selection is, like reinforced behavior, "selection by consequences". Though, as he said, natural selection has now "made its case," he regretted that essentially the same process, "reinforcement", was less ...
