Abstract: 　The hand preference of 20 Sichuan golden monkeys (Rhinopithecus roxellana) was studied during their food reaching. In this small sample, population level lateralization was not found, even though half of them showed strong right hand preference. Age effect was not significant even though the incidence of hand preference was higher in adults than in young. Similarly,these monkeys did not exhibit sex-related difference in the direction and strength of hand preference. We suggest that the hand preference of Sichuan golden monkeys should be further studied in a large sample of animals, involving in complex tasks used.
