Abstract
We report here studies of spatial imprinting on the formation of a cyclical food-procuring skill in a multiple-choice maze in adult DBA/2J C57BL/6J F1 mice in conditions of free choice. In contrast to control mice initially trained in conditions of environmental constancy, the experimental group was exposed to changes in the maze space over the 3 min of 1–2 trials. Control mice were able to solve the food-procuring task after nine experiments, while experimental animals remained at the situational behavior stage, which was inappropriate to the task conditions. The inability to organize the skill on the principle of least action provoked a negative psychoemotional state. The study results showed that spatial information obtained during the period of familiarization with the environment was not only fixed and apparent at the stage of organizing the skill, but also had significant influences on the direction and result of the cognitive process.
