The measurement of intelligence : $b an explanation of and a complete guide for the use of the Standard revision and extension of the Binet-Simon intelligence scale
REMARKS. At first thought it would seem that the demands made by this
test upon intelligence could not be very great. Sound associations
between words may be contrasted unfavorably with associations like those
of cause and effect, part to whole, whole to part, opposites, etc. But
when we pass from _a-priori_ considerations to an examination of the
actual data, we find that the giving of rhymes is closely correlated
with general intelligence.
The 9-year-olds who test at or above 10 years nearly always do well in
finding rhymes, while 9-year-olds who test as low as 8 years seldom
pass. When a test thus shows high correlation with the scale as a whole,
we must either accept the test as valid or reject the scale altogether.
While the feeble-minded do not do as well in this test as normal
children of corresponding mental age, the percentage successes for them
rises rapidly between mental age 8 and mental age 10 or 11.
Closer psychological analysis of the processes involved will show why
this is true. To find rhymes for a given word means that one must hunt
out verbal associations under the direction of a guiding idea. Every
word has innumerable associations and many of these tend, in greater or
less degree, to be aroused when the stimulus word is given. In order to
succeed with the test, however, it is necessary to inhibit all
associations which are not relevant to the desired end. The directing
idea must be held so firmly in mind that it will really direct the
thought associations. Besides acting to inhibit the irrelevant, it must
create a sort of magnetic stress (to borrow a figure from physics) which
will give dominance to those associative tendencies pointing in the
right direction. Even the feeble-minded child of imbecile grade has in
his vocabulary a great many words which rhyme with _day_, _mill_, and
_spring_. He fails on the test because his verbal associations cannot be
subjugated to the influence of a directing idea. The end to be attained
does not dominate consciousness sufficiently to create more than a faint
stress. Instead of a single magnetic pole there is a conflict of forces.
The result is either chaos or partial success. _Mill_ may suggest
_hill_, and then perhaps the directing idea becomes suddenly inoperative
and the child gives _mountain_, _valley_, or some other irrelevant
association. The lack of associations, however, is a more frequent cause
of failure than inability to inhibit the irrelevant.
