As the basis of the preliminary study on the lateral dominance of human hand capabilities, this study examines the hypotheses as follows; whether 10 hand digits may have different reaction times in a choice reaction task; and whether reaction times may differ between the left and right hands or not. A choice reaction experiment was conducted to obtain a data on each hand digit reaction time which is the time from the beginning of a stimulus to the beginning of the reaction to it. Twenty one male, right handed college students served as the subjects. The subject placed his 10 digits on the 10 switches which correspond to the horizontally located LED lamps used as a stimulus. The data indicates that the mean reaction times are different in hand digits. The ANOVA and Duncan's multiple range test reveal the significant differences in the subjects and in hand digits but not in hands. The shortest time is observed in the left and right little fingers while the longests are the left and right middle fingers. The thumb, index, and ring fingers have longer times, respectively between the two extremes. The shortest time of the little fingers and the insignificant difference between the hands may require a further speculation of experimental methods.
