[The behavioral characteristics of rats selected for their learning capacity].
Experiments were conducted in rat strains selected for high (KHA) and low (KLA) levels of the elaboration of conditioned reflex of active avoidance in shuttle box. KHA rats, as compared with the KLA ones, showed considerably higher indices of learning the shuttle avoidance, a greater number of intersignal runs during learning, a higher level of motor activity under open field conditions and its more marked extinction. These data point at the role of both associative and non-associative processes in the formation of active avoidance reflex. During 5 days of reflex training the rats of both strains retained a high level of defecation until the end of the test that pointed at the emotional strain unceasing in spite of the automatization of the reflex.
