Description
Summary:	At the process of learning in an 8-arm radial maze the impulsive animals found the reinforced arms and ate the pellets faster, than self-control and ambivalent rats. They committed less working memory errors at the cue memory task, though there was no difference in the rate of learning and a number of errors of reference memory in animals of different groups. During reversion learning at the change of reinforced arms on unre- inforced, and vice versa, the impulsive animals spent less time to enter into the reinforced arms compared to other groups. They had fewer errors of cue working and reference memory, but the rate of learning was the same as in other groups. The date obtained indicate that in the impulsive rats in comparison with the other groups of animals are stronger the general motor activity and better the working memory.
