Optimization of research instrumental activity during exposure to a low-intensive conditioned stimulus

Research activity of rats is determined by the intensity of conditioned stimulus and probability of initially accidental correct performance of instrumental reaction during training in an arbitrary environment. If the values of this probability are unfavorable for training, attenuation of the intensity of conditioned stimulus causes a decrease in the research activity as a result of deterioration of conditions of information. By contrast, the values of probability of accidental correct performance of the reaction optimal for training promote a higher information significance of each research reaction, this decreasing the relationship between research activity and intensity of conditioned stimulus.[PUBLICATION ABSTRACT]
