Successive positive contrast in one-way avoidance learning.
The main finding of these experiments was a positive contrast effect in one-way avoidance learning. Experiment 1 showed that increasing safety time during one-way avoidance training led to improved performance, surpassing that of a control group that had received the high reward (safe time) from the beginning of training. Experiment 2 showed that a similar positive contrast effect occurred when...
متن کاملThe effects of scopolamine hydrobromide on one-way and two-way avoidance learning in rats.
-Previous studies have shown certain striking similarities between the behavioral effects produced by some anticholinergic drugs and the effects produced by hippocampal destruction. To investigate this parallel more thoroughly, scopolamine hydrobromide w a s administered to rats in one-way and two-way active avoidance learning situations. The drugged animals showed improved learning of the two-...
متن کاملFacilitatory effects of electrical stimulation of the hippocampus on a one way active avoidance response in cats.
Effects of a low intensity electrical stimulation of the hippocampus (HiSt) on acquisition, performance and retention of a one-way active avoidance response (AAR) were studied in four groups of cats. The animals were first trained in avoiding an electric foot-shock signalled by a CS (500 Hz tone) presentation and then they were tested or retention until the response extinguished. The HiSt was a...
متن کاملThe effect of ECS on one-trial avoidance learning.
In a recent article, Coons and Miller (1960) raise the question as to whether previous studies which have purported to show that ECS induces a retrograde amnesia can be accounted for by ECS-induced fear of the goal. In the present study 5s were given a single ECS after making a response which was punished by shock to the feet. In a similar study, Pearlman, Sharpless, and Jarvik (1959) have show...
متن کاملselecting an optimum configuration of urban one-way and two-way streets using genetic algorithms
optimization is an important methodology for activities in planning and design. the transportation designers are able to introduce better projects when they can save time and cost of travel for project by optimization methods. most of the optimization problems in engineering are more complicated than they can be solved by custom optimization methods. the most common and available methods are he...
