1) Th.e reaction time of the avoidance movement of jumping off toward a given place, which was regarded as an indicator of the quickness of movement of the group of muscles of the lower limbs, was measured and compared with the quickness of these of the upper limbs. 2) The reaction time of movement of placing one's hand from one to the other of the two pushing-plates, by pushing which the electric circuits were closed, was measured. The reaction time of the commencement of the movement was similar to the simple reaction time, and its correlation with age was not high. The time taken to place one's hand on the other plate tended to be a little longer with subject of middle and high ages. 3) The dispersion of the values of reaction time of both the commencement and the termination of movement when measured repeatedly was similar to that of the simple reaction time, but the dispersion of the difference between these two kinds of reaction times, that is, that of the time taken to move one's hand was smaller than that of the simple reaction time. 4) Concerning one-step jumping aside to the right hand side, the reaction time of the commencement of movement under the condition that the legs were moved one by one was longer than the simple reaction time, and was also longer than that of the simultaneous movement of the both legs. The reaction time of both the commencement and the termination of movement was longer with higher ages, and was longer with women than with men. This relation was more evident in the successive movement of each legs than in the simultaneous one. The frequency distribution curve obtaind by repeating the measurement of the reaction time of jumping off showed a nearly normal distribution curve. The correlation between the reaction time of hand movement and that of jumping off was not so high.
