Form Test of the CPM
almost universally applicable method of demonstrating
the problems is to present each in the form of a board
with a part removed, and for the options from which a
choice has to be made to be available on movable pieces,
each of which fits the space in the board. Those taking
the test can be shown that each piece fits the gap in
the board but that only one completes the pattern. By
placing a selected piece in position, people can see the
results of their judgement The inbuilt training in the
method of working teaches them to be careful, without
altering the number of problems they are capable of solving
by direct inference.
Board Form of the Test can be demonstrated satisfactorily
to persons of almost any race speaking any language. It
is also one of the few tests which can be used satisfactorily
with people who are suffering from partial paralysis,
deafness or defective speech, and which will give a consistent
reliable and psychologically valid estimate of their present
capacity for rational judgement regardless of their specific
the ages of 3 and 6 years, a child's interest and attention
are usually too mobile, and output of intellectual activity
too capricious, for any mental test to give a highly reliable
prediction of subsequent intellectual development. For
this reason, it is doubtful if the results obtained with
the Board Form of the Test have, with infants, greater
prognostic value than the results obtained with other
mental tests. There is reason to think, however, that
the results obtained with the Board Form of the Test are
psychologically valid as far as they assess a child's
present output of intellectual activity, whatever his
or her knowledge and education.
routine work with very young children, for the clinical
assessment of intellectual deficiency or deterioration,
and for cross-cultural studies, the Board Form of the
Test has obvious advantages. For some psychological enquiries,
it has also the advantage over the Book Form of the Test
in that solutions by trial and error can be observed,
recorded, and compared with solutions by direct perception
and inference. Solutions by the former method can be kept
separate from solutions by the latter. To evaluate the
results, they need not be included in the total score
on the Test. By omitting them, the results obtained when
the Board Form of the Test is used can be satisfactorily
equated with the results obtained when the Book Form of
the Test is used.
from the circumstances already indicated, the Board Form
of the Test is chiefly useful for psychological research.
For this purpose it has two merits: it overcomes the limitations
of both a "pencil and paper" test and a "performance"
test, and it also makes it possible to record easily and
accurately the successive judgements a person acts on
in attempting to solve a progressive series of problems.
In this way information is obtained concerning the mental
operations involved and the kinds of error made in problem
