Overlearning and frustration effects during extinction of operant responding
The two experiments in this study investigated overtraining effects and frustration effects during extinction of combined runway-barpress responding by albino rats The chain of runway-barpress responding provided discrete ...
Adenalin, sodium amobarbital, and the "Kamin effect"
108 rats were given training in an approach-avoidance spatial conflict situation. Following completion of training, Ss were tested for retention of the avoidance response after intervals of 15 min., 3 hrs., or 24 hrs. ...
Acquisition of a shuttlebox avoidance task with high and low shock following different durations of treatment with dl parachlorophenylalanine
This study investigated acquisition of a shuttlebox avoidance task using high (1.00 ma) and low (0.25 ma) shock levels, following different durations of treatment with dl- parachlorophenylalanine (PCPA), a depletor of brain ...
Discriminative odor cues in the runway; further validation and a method for control
Twenty-four albino rats were tested in a 5' straight alley on a double alternation pattern of reward and non- reward--a pattern which previous work has shown to be impossible for the rat to perform on the basis of internal ...
Genetic strain differences in the opiate abstinence syndrome
Five strains of rats, two outbred (Sprague-Dawley and Holtzman) and three inbred strains (Buffalo, Lewis, and Fisher), received subcutaneous implants of either morphine or placebo pellets. The naloxone-precipitated opiate ...
