The Effects Of Three Levels Of Social Interaction On The Maintenance Of Sidman Avoidance In Rats, John Lewis Cofer
The Effects Of Three Levels Of Social Interaction On The Maintenance Of Sidman Avoidance In Rats, John Lewis Cofer
Master's Theses
In 1965 Zajonc theorized that the effect of the presence of others was to facilitate the maintenance of a behavior. However, opposite results have been found when rat subjects were tested with shock used as a reinforcer. It was hypothesized that shock elicited aggression interfered with responding, producing performance decrement, rather than facilitation. A wheel-turn Sidman avoidance procedure was used to study maintenance behavior in rats under three levels of social interaction: single subject, two subjects separated by a barrier to prevent shock elicited aggressions (the companion paradigm), and two subjects not separated in the. test chamber (the physical paradigm). …
Differential Assessment Of Retrograde Amnesia Produced By Hypothermia Following One-Trial Avoidance Conditioning, Duane E. Brookhart
Differential Assessment Of Retrograde Amnesia Produced By Hypothermia Following One-Trial Avoidance Conditioning, Duane E. Brookhart
Master's Theses
Two different measures of the retention of avoidance conditioning, frequently used in the investigation of retrograde anmesia (RA), were examined. Rats were given a single training trial on either passive or active avoidance in a conventional black-white discrimination apparatus and step-through latencies were recorded. Task sequence, footshock and hypothermia were experimentally varied across eight groups of subjects. Each S was returned to the experimental apparatus 24 hours after training and given retention tests on both passive and active avoidance tasks. Test trial latencies failed to demonstrate any retention deficits attributable to RA, and both passive and active avoidance test latencies …
