[Concerning a conflict nature of the "spatial delayed response" test].
Neuropsychological analysis of rats' performance of the spatial delayed response (SDR) in different testing conditions revealed a conflict nature of the indirect variation of the SDR task. It was found that the execution of the response based on the image short-term memory interferes with the response differentiation acquired during learning the rule of indirect SDR performance, i.e., during acquisition of the spatial discrimination. It is evident that the maximization of conditions, which promote the acquisition of response differentiation (additional training of animals for spatial discrimination), makes it difficult to perform the indirect variation of the SDR task, while the minimization of these conditions facilitates the correct task performance.
