Active Avoidance: Neural Mechanisms and Attenuation of Pavlovian Conditioned Responding.
Patients with anxiety disorders often experience a relapse in symptoms after exposure therapy. Similarly, threat responses acquired during Pavlovian threat conditioning often return after extinction learning. Accordingly, there is a need for alternative methods to persistently reduce threat responding. Studies in rodents have suggested that exercising behavioral control over an aversive stimulu...
متن کاملExtinction of responding maintained by timeout from avoidance.
The resistance to extinction of lever pressing maintained by timeout from avoidance was examined. Rats were trained under a concurrent schedule in which responses on one lever postponed shock on a free-operant avoidance (Sidman) schedule (response-shock interval = 30 s) and responses on another lever produced 2 min of signaled timeout from avoidance on a variable-ratio 15 schedule. Following ex...
متن کاملEffects of inescapable shock upon subsequent escape and avoidance responding.
Exposure of dogs to inescapable shocks under a variety of conditions reliably interfered with subsequent instrumental escape-avoidance responding in a new situation. Use of a higher level of shock during instrumental avoidance training did not attenuate interference; this was taken as evidence against an explanation based upon adaptation to shock. Ss curarized during their exposure to inescapab...
متن کاملAvoidance responding in dogs trained in symmetrical or asymmetrical go, no-go differentiation.
The acquisition and the consolidation processes of avoidance responding in go, no-go differentiation with asymmetrical and symmetrical reinforcement procedures were studied in 49 male mongrel dogs. Differentiation training procedures with asymmetrical and symmetrical reinforcement were contrasted by the occurrence of painful shock on negative trials. The quality of conditioned stimuli and their...
متن کاملVisual avoidance in phobia: particularities in neural activity, autonomic responding, and cognitive risk evaluations
We investigated the neural mechanisms and the autonomic and cognitive responses associated with visual avoidance behavior in spider phobia. Spider phobic and control participants imagined visiting different forest locations with the possibility of encountering spiders, snakes, or birds (neutral reference category). In each experimental trial, participants saw a picture of a forest location foll...
