DIFFERENTIATION OF VISUAL STIMULI BY MACAQUE AND CHIMPANZEE

In a pilot project, comparative differences in recognition and differentiation of stimuli, associated with one separation symptom, macaque and chimpanzee are established. The differences of temporal parameters of correct and incorrect responses of both monkeys are detected. The study suggests that greater time spent on the selection of the “correct” stimulus by chimpanzees, unlike macaque, is caused by decision-making, and its erroneous response caused by a random solution of the problem.
