Rouiller Distinction between hand dominance and hand preference in primates: a behavioral investigation of manual dexterity in nonhuman primates (macaques) and human subjects Brain and Behavior 3
The aim of the present study was to confront hand preference (hand chosen in priority to perform a manual dexterity task) and hand dominance (hand with best motor performance) in eight macaques (Macaca fascicularis) and in twenty human subjects (10 left and 10 right handers). Macaca fascicularis do not exhibit a clear hand preference, neither at population level, nor at individual level. For human subjects, hand preference mostly followed the self-assessment of lateralization given by the subjects and the questionnaire. The present study argues for dissociating hand preference and hand dominance, especially in macaque monkeys.
