An Analysis of Extinction-Cue Features in the Reduction of Operant Behavior Relapse

The Psychological Record - The present free operant conditioning experiments with rats examined the impact of manipulating different traits of an extinction-cue on ABA renewal. All rats were...     

Experiencing extinction within a task makes nonextinguished information learned within a different task context-dependent

In two experiments with rats, we analyzed the effect of experiencing extinction in one task on the context specificity of a new association learned within a different task. Rats were trained to run in a runway for water in Task 1, and received taste aversion conditioning in Task 2 (the tasks were reversed in Exp. 2). Half of the rats received conditioning and extinction of Task 1 in Context A, whereas the other half received no extinction. Then all animals received training in the alternate task in Context B, prior to testing in Context C. When they were tested in Context C, Task 2 performance was attenuated if Task 1 had been extinguished prior to Task 2. These results are similar to those we have reported in humans, and consistent with the idea that extinction prompts attention to contexts, regardless of whether or not the contexts were involved in extinction.
