Learning the two-hand coordination test

Abstract

Industrial concerns which use the two-hand coordination test usually base their prediction of aptitude on the mean performance of 5-10 trials. When the 5 highest and the 5 lowest men on such scores were given 100 trials, all of them were able to make perfect performances. The resultant learning curves and data lead the author to suggest: (1) that a minimum of 20 trials be given to each applicant and the mean of the last 5 trials instead of the first 5 be used as the normative score and (2) that the rate at which the subject reduces his range of errors per group of 5 trials may be used as a valuable supplement in predicting aptitude for this type of coordination.
