ON THE DEGREE OF ASSOCIATION BETWEEN REACTION TIMES IN THE CASE OF DIFFERENT SENSES

(1) Introductory. It seems of interest to investigate on adequate material the relative extent to which a short reaction time depends on the acuteness of the sense concerned, and on what we may term mental briskness. If reaction times to sight and sound depend largely on acuteness of sight and acuteness of hearing the correlations between acuteness and reaction time will be high; if, on the other hand, mentality is the chief factor in reaction time, we should expect a high correlation between reaction times for the different senses. Such is the problem which the present paper proposes to discuss.
