title: [The volume of reinforcement and the structure of rat behavior in a radial labyrinth].
abstract: In rats choice reaction was elaborated in 12 passages radial labyrinth with different volumes of food only in six of twelve passages. Then the conditions were modified: the first group of rats in the beginning of the experiment was placed to another labyrinth sector, and in the second group the food volume was changed in passages. In new situations in animals of both groups the reaction efficiency temporarily decreased, simultaneously the correction of behaviour structure took place. The character of behavioural tactics (tendencies to visit passages with larger food volume at the beginning of the experiment, spatial-motor asymmetry etc.) is described in dynamics of adaptation to new conditions. Factors determining the rats behaviour structure are discussed.
