art, the stability of Scientific
Management, because it is based on universal cooeperation. This
provides an intensity and a continuity of interest that would still
hold, even though some particular element might lose its interest.

THIS RELATIONSHIP ALSO PROVIDES FOR ASSOCIATIONS.--The close
relationship of all parts of Scientific Management provides that all
ideas are associated, and are so closely connected that they can act
as a single group, or any selected number of elements can act as
a group.

SCIENTIFIC MANAGEMENT ESTABLISHES BRAIN GROUPS THAT HABITUALLY
ACT IN UNISON.--Professor Read, in describing the general mental
principle of association says, "When any number of brain cells have
been in action together, they form a habit of acting in unison, so
that when one of them is stimulated in a certain way, the others
will also behave in the way established by the habit."[31] This
working of the brain is recognized in grouping of motions, such as
"playing for position."[32] Scientific Management provides the
groups, the habit, and the stimulus, all according to standard
methods, so that the result is largely predictable.

METHOD OF ESTABLISHING SUCH GROUPS IN THE WORKER'S BRAIN.--The
standard elements of Scientific Management afford units for such
groups. Eventually, with the use of such elements in instruction
cards, would be formed, in the minds of the worker, such groups of
units as would aid in foreseeing results, just as the foreseeing of
groups of moves aids the expert chess or checker player. The size
and number of such groups would indicate the skill of the worker.

That such skill may be gained quickest, Scientific Management
synthesizes the units into definite groups, and teaches these to the
workers as groups.

TEACHING DONE BY MEANS OF MOTION CYCLES.--The best group is that
which completes the simplest cycle of performance. This enables the
worker to associate certain definite motions, to make these into a
habit, and to concentrate his attention upon the cycle as a whole,
and not upon the elementary motions of which it is composed.

For example--The cycle of the pick and dip process of
bricklaying is to pick up a brick and a trowel full of mortar
simultaneously and deposit them on the wall simultaneously.[33] The
string mortar method has two cycles, which are, first to pick a
certain number of trowelfuls of mortar and deposit them on the wall,
and then to pick up a corres
