(4) errors do not increase or decrease with speed-changes;
(5) the feet are equally accurate.
For individual results:
(1) fatigue-lapses and cases of large error-increases are noted in a number of subjects, both for visual and non-visual records;
(2) further, evidence is available as to the indifference to visual control;
(3) no preference for either foot is to be discovered.
