Abstract:
In two experiments with rats, we investigated the effects of using multiple contexts during extinction on renewal of lever-pressing behavior. During the first phase of both experiments, rats were reinforced to press a lever for food in Context A. Then, responses underwent extinction. For half of the animals, extinction sessions were conducted in a single context, whereas the other half received extinction in three different contexts. In Experiment 1, we observed that extinction in multiple contexts eliminated ABC renewal, but had no detectable impact on ABA renewal. Experiment 2 revealed that conducting extended extinction training in multiple contexts attenuated ABA renewal. Theoretical and clinical implications of the present findings are discussed.
