Copying A Diamond

PROCEDURE. On a white cardboard draw in heavy black lines a diamond with
the longer diagonal three inches and the shorter diagonal an inch and a
half. The specially prepared record booklet contains the diamond as well
as many other conveniences.

Place the model before the child with the longer diagonal pointing
directly toward him, and giving him _pen and ink_ and paper, say: "_I
want you to draw one exactly like this._" Give three trials, saying each
time: "_Make it exactly like this one._" In repeating the above formula,
merely point to the model; do not pass the fingers around its edge.

Unlike the test of copying a square in year IV, there is seldom any
difficulty in getting the child to try this one. By the age of 7 the
child has grown much less timid and has become more accustomed to the
use of writing materials.

Note whether the child draws each part carefully, looking at the model
from time to time, or whether the strokes are made in a more or less
haphazard manner with only an initial glance at the original.

After each trial, say to the child: "_Is it good?_" And after the three
copies have been made say: "_Which one is the best?_" Retarded children
are sometimes entirely satisfied with the most nondescript drawings
imaginable, but they are more likely correctly to pick out the best of
three than to render a correct judgment about the worth of each drawing
separately.

SCORING. The test is passed if _two of the three_ drawings are at least
as good as those marked satisfactory on the score card. The diamond
should be drawn approximately in the correct position, and the diagonals
must not be reversed. Disregard departures from the model with respect
to size.

REMARKS. The test is a good one. Age and training, apart from
intelligence, affect it only moderately. There are few adult imbeciles
of 6-year intelligence who are able to pass it, while but few subjects
who have reached the 8-year level fail on it.

This test was located in year VII of the 1908 scale, but was shifted to
year VI in Binet's 1911 revision. The change was without justification,
for Binet expressly states, both in 1908 and 1911, that only half of the
6-year-olds succeed with it. The large majority of investigations have
given too low a proportion of successes at 6 years to warrant its
location at that age, particularly if pen is required instead of pencil.
Location at year VI would be warranted only on the condition that the
use of pencil be permitted and only one success required in three
trials.
