Consolidation of CS and US representations in associative fear conditioning.
Much attention has been paid to the associative processes that are necessary to fuse together representations of the various components of an episodic memory. In the present study, we focus on the processes involved in the formation of lasting representations of the individual components that make up a fear-conditioning episode. In one-trial contextual fear conditioning experiments, weak condit...
متن کاملThe conditioning theory of fear-acquisition: a critical examination.
The conditioning theory of fear-acquisition is outlined and the supporting evidence and arguments presented. It is argued that the theory lacks comprehensiveness and is also inadequate in other respects. Six arguments against acceptance of the theory are advanced. People fail to acquire fears in what are theoretically fear-evoking situations (e.g. air raids). It is difficult to produce conditio...
متن کاملLearning strategies during fear conditioning.
This paper describes a model of fear learning, in which subjects have an option of behavioral responses to impending social defeat. The model generates two types of learning: social avoidance and classical conditioning, dependent upon (1) escape from or (2) social subordination to an aggressor. We hypothesized that social stress provides the impetus as well as the necessary information to stimu...
متن کاملAmygdala and hippocampal activity during acquisition and extinction of human fear conditioning.
Previous functional magnetic resonance imaging (fMRI) studies have characterized brain systems involved in conditional response acquisition during Pavlovian fear conditioning. However, the functional neuroanatomy underlying the extinction of human conditional fear remains largely undetermined. The present study used fMRI to examine brain activity during acquisition and extinction of fear condit...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
