Teaching Under Scientific Management Trains the Senses. — Scientific Management, in teaching the man, aims to train all of his senses possible. Not only does each man show an aptitude for some special sense training, [9] but at certain times one sense may be stronger than another; for example, the sense of hearing, as is illustrated by the saying, "The patient in the hospital knoweth when his doctor cometh by the fall of his footsteps, yet when he recovereth he knoweth not even his face." At the
time that a certain thing becomes of interest, and becomes particularly interesting to one sense, that sense is particularly keen and developed.
Scientific Management cannot expect, without more detailed psychological data than is as yet available, to utilize these periods of sense predominance adequately. It can, and does, aim to utilize such senses as are trained, and to supply defects of training of the other senses.
Such Training Partially Determines the Quality of the Work. — The importance of sense training can scarcely be overestimated. Through his senses, the worker takes in the directions as to what he is to do, and on the accuracy with which his senses record the impressions made upon them, depends the mental model which he ultimately follows, and the accuracy of his criticism of the resulting physical object of his work. Through the senses, the worker sets his own task, and inspects his work.
