TOPIC:  BEHAVIOURAL AND NEUROBIOLOGICAL MECHANISMS OF EXTINCTION IN PAVLOVIAN AND INSTRUMENTAL LEARNING

 

 

Abstract: Pavlovian and instrumental learning are two fundamental forms of learning that contribute to behavior in a variety of ways, in

both human and non-human animals. In Pavlovian extinction, repeated presentation of a signal without its reinforcer weakens behavior

evoked by the signal; in instrumental extinction, repeated occurrence of a voluntary action without its reinforcer weakens the strength of the

actions. In both cases, contemporary research at both the behavioural and neural levels of analysis has been guided by a set of extinction

principles that were first generated by research conducted at the behavioral level. Both Pavlovian and instrumental extinction are at

least partly controlled by a form of context-specific inhibitory learning, and both involve a neural circuit including the hippocampus and the

medial prefrontal cortex.

 

Dr. Travis Todd graduated from the University of Winnipeg where he worked in the Doug Williams lab. He subsequently completed a PhD with Mark Bouton at the University of

Vermont. Travis won a National Research Service Award from the National Institute of Mental Health and is currently a Postdoctoral Fellow in the David Bucci lab at Dartmouth College. Read
