Effects 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 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 کاملEscape and avoidance conditioning in human subjects without their observation of the response.
An invisibly small thumb-twitch increased in rate of occurrence when it served, via electromyographic amplification, to terminate or postpone aversive noise stimulation. Subjects remained ignorant of their behavior and its effect. Their cumulative response curves resembled those obtained in similar work with animals. Other subjects, informed of the effective response, could not produce it delib...
متن کاملFailure to escape traumatic shock.
Dogs which had 1st learned to panel press in a harness in order to escape shock subsequently showed normal acquisition of escape/ avoidance behavior in a shuttle box. In contrast, yoked, inescapable shock in the harness produced profound interference with subsequent escape responding in the shuttle box. Initial experience with escape in the shuttle box led to enhanced panel pressing during ines...
متن کاملEscape from shock versus escape from shock accompanied by a visual stimulus in rats.
Two groups of 15 rats each were trained in a shuttle box to escape foot-shock either unsignalled or presented in compound with a visual cue: darkness. The visual cue presented in shock compartment amplifies the behavioral tendency actually prevailing in the response repertory of the rat. During the 1st session the compound enhanced the species-specific flight resulting in shortening of the rat'...
