[Comparative characteristics of psychoemotional patterns in Albino and Wistar rats].
Analysis of psychoemotional behavioral component in Albino and Wistar rats during solving a cognitive task showed that intra-population differences were determined by the relationship between passive and active forms of unconditioned reactions. Quick-learning rats from both populations were characterized by the dominance of active forms of psychoemotional reactions over the course of training. The learning process in slow-learning rats was accompanied mainly by passive emotional manifestations, whereas active reactions dominated at the stage of habit realization. Passive forms of manifestations prevailed over active forms over the course of training in both Albino and Wistar rats which failed to solve the task. The interpopulational psychoemotional differences were quantitative and depended only on the learning styles. Wistar strain was characterized by a decreased percent of animals which were able to solve a cognitive task (40% versus 80% in Albino rats), affective flatness and decreased tolerance to information loadings.
