(1) that every subject reacts more rapidly with the left hand;
(2) the eyes had little effect as to changing the speed-rate;
(3) single and double hand-movements were equally rapid.
Some subjects, as A., react more rapidly for the shorter lines, though no clearly marked evidence of this speed-increase is to be noted.
For the head, the results for both eyes opened and closed show the impossibility of separating the optimal or preferred rate of speed on the score of visual assistance or because of direction of head-movement.
There is a close agreement of the subject as to his best speed, and this is independent of special conditions; for example,
A. selects 50-57 beats per minute for 1 cm. and 48-68 for 10 cm.; G. has a preference for 61-66 and 56-71; Hu. rises to 103-125 for 10 cm. and selects 68-82 for 1 cm.; Le. 52-55 for 1 cm. and 45-52 for 10 cm., and so on.
We may say, then, that free rate-choice for head-movements results in a selection of some rate of speed that is not affected by the visual sense or direction of movement, and is strictly individualistic, covering a range of 50-130 beats per minute, and not increasing as the amplitude of movement is reduced.
Turning to individual choice of speed-rate, for the feet it will be seen that
(1) the non-visual records closely correspond as to chosen speed, and there is a less close correspondence of visual speeds;
