ABSTRACT
This chapter focuses on the question of how contexts control performance in the presence of fear-evoking conditioned stimuli (CSs). One possibility is that a CS may retain some associative strength, but be behaviorally "silent" because its strength lies below some behavioral threshold. Few models assume that the associative strength of a CS is linearly mapped onto behavior. The basic fear-renewing effect of shifting the context after extinction is consistent with the results that have been obtained with other conditioning paradigms. In general, the author had found so little evidence that would unequivocally support the event-memory model's account of extinction that must question the utility of adding new mechanisms to it to patch it up. The associationist assumes that memory can be understood by an analysis into basic units that are related to one another by a set of basic relations that concatenate to form the structure underlying complex behaviors.
