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.

SENSE TRAINING INFLUENCES INCREASE OF EFFICIENCY.--With the
training of the senses the possibility of increased efficiency
increases. As any sense becomes trained, the minimum visable is
reduced, and more accurate impressions become possible.[10] They
lead to more rapid work, by eliminating time necessary for judgment.
The bricklayer develops a fineness of touch that allows him to
dispense with sight in some parts of his work.

SELECTIVE POWER OF SENSES DEVELOPED.--James defines the sense
organs as "organs of selection."[11] Scientific Management so trains
them that they can
