Abstract: The present study examined hand preference in Macaca radiata based on the results of the tube task and reach task method. The Macaca radiata in the wild environment always used the same hand, whereas, in some conditions, the monkeys used both hands at less frequency. The statistical comparison between the Macaca radiata group of right - hand users versus left - hand users for the tube task and reach task revealed significant differences with variable HI scores. The real values of HI score in hand preference of male and female individuals showed significant differences. The number of male monkeys showing a left - handed preference did not significantly differ in all study sites. The female macaque individuals predominantly used their left hand to pick up food from tubes.
