Abstract:

There are no significant differences attributable to direction of movement in the case of either one- or two-handed movements. The time required to execute the first phase of a movement primary-movement time is, in general, longer for two-handed than for one-handed movements. The time spent in executing the fine, secondary adjustments following the initial gross approaches primary movements to the desired point was less for two hands than for one, the difference being highly significant at the 40 cm. point. The data obtained for two-handed movements on average speed and maximum speed of movement indicate that in both instances the two-handed movements are slower than the one-handed movements when made over comparable distances.
