title: Significance of emotional excitation in the mechanisms of spatial short-term memory in lower apes.
abstract: Correlates of variation in the level of emotional tension are studied in long-term experiments on adult monkeys. The simultaneous appearance of the electrodermal response and of a change in the heart rate is shown to reflect more accurately a rise in the level of emotional tension. Continuous recording of autonomic indexes reveals an increase in tension level during the presentation of conditioned signals and the performance of the motor response in the spatial delayed response test program. The emotiogenic structures are thought to influence the specific mechanisms of short-term memory during the presentation of conditioned signals and the performance of food-procuring instrumental behavior.
