Peer reviewed Peer reviewed

Winterbauer, Neil E.; Bouton, Mark E. – Learning and Motivation, 2011
Three experiments with rat subjects examined resurgence of an extinguished instrumental response using the procedure introduced by Epstein (1983) with pigeons. There were three phases: (1) initial acquisition of pressing on a lever (L1) for pellet reward, (2) extinction of L1, and (3) a test session in which a second lever (L2) was inserted,…

Occasional Reinforced Responses during Extinction Can Slow the Rate of Reacquisition of an Operant Response
Peer reviewed Peer reviewed

Woods, Amanda M.; Bouton, Mark E. – Learning and Motivation, 2007
Three experiments with rats examined reacquisition of an operant response after either extinction or a response-elimination procedure that included occasional reinforced responses during extinction. In each experiment, reacquisition was slower when response elimination had included occasional reinforced responses, although the effect was…

Context and Behavioral Processes in Extinction

Bouton, Mark E. – Learning & Memory, 2004
This article provides a selective review and integration of the behavioral literature on Pavlovian extinction. The first part reviews evidence that extinction does not destroy the original learning, but instead generates new learning that is especially context-dependent. The second part examines insights provided by research on several related…
