Behavioral experiments were run to study the capacities of Macaca mulatta monkeys to perform cognitive tests of different levels of difficulty presented on a computer touch screen. The task consisted of recognizing the dominant orientation in textures with different levels of ordering. Rates of learning were analyzed, along with the proportions of correct responses and task solution times in relation to task difficulty. The extent of exploratory activity was evaluated in parallel, in terms of reactions to unfamiliar objects (the "reaction to a novel object" test). The proportion of correct responses increased with increases in the ordering of the test images and was comparable with results obtained previously in humans in similar experimental conditions. In monkeys, the index of exploratory activity correlated with the rate of learning and was lower in those animals inclined to distraction of attention, i.e., with longer response times. The results obtained in monkeys allow the neural processes occurring in the human brain on recognition of objects to be modeled, from the encoding of the physical properties of images to decision-taking. The interaction between the level of exploratory activity and the rate of learning allows the "reaction to a novel object" test to be used for selecting potential individuals for participation in behavioral experiments, significantly reducing the time spent on training the monkeys to new tasks.
