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 کاملPavlovian Control of Escape and Avoidance.
To survive in complex environments, animals need to have mechanisms to select effective actions quickly, with minimal computational costs. As perhaps the computationally most parsimonious of these systems, Pavlovian control accomplishes this by hardwiring specific stereotyped responses to certain classes of stimuli. It is well documented that appetitive cues initiate a Pavlovian bias toward vig...
متن کاملConditioned stimulus determinants of conditioned response form in Pavlovian fear conditioning.
Four experiments using barpress conditioned suppression in rats found that tone evoked more freezing (immobility) than did light. Still, tone and light appeared to have similar conditioned value as assessed by suppression in Experiments 1, 2, and 3, and by blocking, second-order conditioning, and overconditioning assays in Experiments 1, 2, and 3, respectively. Experiment 4 arranged for tone to...
متن کاملSome factors involved in the stimulus control of operant behavior.
The stimuli which are present when an operant is reinforced modify the subsequent frequency of emission of the response. For example, if a hungry pigeon is reinforced with food when it pecks a translucent key upon which a monochromatic light is projected, it will subsequently peck most rapidly when the light is of the same wavelength. Guttman (3) has reported that a difference of 2 millimicrons...
متن کاملInterdependence of measures in pavlovian conditioned freezing.
Pavlovian conditioned freezing is an intensively utilized paradigm that has become a standard model of memory and cognition. Despite its widespread use, the interdependence among each measure commonly reported in fear conditioning studies has not been described. Using mice, we examine the relationship of each common freezing measure (Training Baseline, Post-Shock freezing, Contextual Fear, Tone...
