Features of participation of spatial memory in choice reactions of white rats.

A study was made of the behavior of rats preliminarily trained to return to the same reinforcement site when that site was changed periodically. It was determined that after finding the new reinforcement site, the rats are able to optimize their behavior to correspond to the new location. Optimization of behavior consisted in shifting the direction of the course toward the new location of reinforcement and (or) in selective shifts before the blinds to correspond to the locations of obtaining reinforcement in the experiment. The increased role of the working memory and of the apparatus of probable prediction in selection is proposed as the basis for optimization of behavior.
