Maladaptive behavioral consequences of conditioned fear-generalization: a pronounced, yet sparsely studied, feature of anxiety pathology.
Fear-conditioning experiments in the anxiety disorders focus almost exclusively on passive-emotional, Pavlovian conditioning, rather than active-behavioral, instrumental conditioning. Paradigms eliciting both types of conditioning are needed to study maladaptive, instrumental behaviors resulting from Pavlovian abnormalities found in clinical anxiety. One such Pavlovian abnormality is generaliza...
متن کاملDifferent projections of the central amygdaloid nucleus mediate autonomic and behavioral correlates of conditioned fear.
The purpose of the present study was to determine whether lesions of areas projected to by the central amygdaloid nucleus (ACE) would disrupt the classical conditioning of autonomic and/or behavioral emotional responses. The areas studied included 3 projection targets of the ACE: the lateral hypothalamic area (LH), midbrain central gray (CG) region, and bed nucleus of the stria terminalis (BNST...
متن کاملGeneralization of Conditioned Fear and Obsessive-Compulsive Traits
Generalization of conditioned fear refers to the transfer of the conditioned fear response to stimuli that resemble the original conditioned stimulus. Overgeneralization of conditioned fear has been associated with panic disorder and generalized anxiety disorder and may be relevant to obsessive-compulsive (OC) symptoms as well. This study represents the first attempt to determine the degree to ...
متن کاملConditioned Fear Acquisition and Generalization in Generalized Anxiety Disorder.
Abnormal fear conditioning processes (including fear acquisition and conditioned fear-generalization) have been implicated in the pathogenesis of anxiety disorders. Previous research has shown that individuals with panic disorder present enhanced conditioned fear-generalization in comparison to healthy controls. Enhanced conditioned fear-generalization could also characterize generalized anxiet...
متن کاملDevelopmental aspects of fear: Comparing the acquisition and generalization of conditioned fear in children and adults
Most research on human fear conditioning and its generalization has focused on adults whereas only little is known about these processes in children. Direct comparisons between child and adult populations are needed to determine developmental risk markers of fear and anxiety. We compared 267 children and 285 adults in a differential fear conditioning paradigm and generalization test. Skin condu...
