gth, methods of measurement under
psychology. This, for at least two most important reasons, which
will actually improve him as a measurer, i.e.--

1. The student will discover, in the books on experimental
psychology and in the "Psychological Review," a marvelous array of
results of scientific laboratory experiments in psychology, which
will be of immediate use to him in his work.

2. He will receive priceless instruction in methods of
measuring. No where better than in the field of psychology, can one
learn to realize the importance of measurements, the necessity for
determination of elements for study, and the necessity for accurate
apparatus and accuracy in observation.

Prof. George M. Stratton, in his book "Experimental Psychology
and Culture,"--says "In mental measurements, therefore, there is no
pretense of taking the mind's measure as a whole, nor is there
usually any immediate intention of testing even some special faculty
or capacity of the individual. What is aimed at is the measurement
of a limited event in consciousness, such as a particular perception
or feeling. The experiments are addressed, of course, not to the
weight or size of such phenomena, but usually to their duration and
intensity."[2]

The emphasis laid on a study of elements is further shown in the
same book by the following,--"The actual laboratory work in
time-measurement, however, has been narrowed down to determining,
not the time in general that is occupied by some mental action, but
rather the shortest possible time in which a particular operation,
like discrimination or choice or association or recognition, can be
performed under the simplest and most favorable circumstances.[3]
The experimental results here are something like speed or racing
records, made under the best conditions of track and training. A
delicate chronograph or chronoscope is used, which marks the time in
thousandths of a second."

MEASUREMENT IN PSYCHOLOGY RELATED TO MEASUREMENT IN
MANAGEMENT.--Measurement in psychology is of importance to
measurement in management not only as a source of information and
instruction, but also as a justification and support. Scientific
Management has suffered from being called absurd, impractical,
impossible, over-exact, because of the emphasis which it lays on
measurement. Yet, to the psychologist, all present measurement in
Scientific Management must appear coarse, inaccurate and of
immediate and passing
