Abstract
In most individuals, there is a significant difference in hand dominance and this suggests that sensorimotor tasks, such as reaction time, would demonstrate a difference in performance tasks conducted with dominant versus non-dominant hand. In this study, comparisons were made between the reaction time of the dominant to the nondominant hand, the reaction time of the male participants to that of the female participants, the reaction time variability of the dominant hand of the male participants to that of the dominant hand of female participants, and finally the reaction time variability of the nondominant hand of the male participants to that of the female participants. The study was conducted virtually with participants performing a set of instructions emailed to them. The results demonstrated that the reaction time of the dominant hand was faster than that of the nondominant hand in all participants, the reaction time of the male participants was faster than that of the female participants, the reaction time variability of the dominant hand was higher in male than in female participants, and lastly, the reaction time variability of the nondominant hand was lower for the male than in the female participants.
