There are other cases in
which drawings do not
necessarily reflect what is
perceived. Clinical
psychologists and psychiatrists
make use of a diagnostic tool
known as the Bender-Gestalt
test. Many psychologists have
interpreted the errors
individuals make in copying
various geometrical patterns on
this test as perceptual in
origin. For reasons similar to
those given above, it seems to
me to be highly unlikely that
this is the case. Rather, for
unknown reasons, individuals
do not draw what they perceive.
Similar errors of reasoning
were made in the history of
psychology with respect to
memory and drawing. To study
how a figure was remembered,
subjects were asked to draw it
from memory. Later it was
realized that there were better
ways to probe the accuracy of
memory than by a drawing task.
Given these confusions, it is
important to discuss the
relevance of perception to
drawing or painting. As will
become evident, I believe that,
in certain cases, what we draw
does reflect how we perceive.
But from the examples above it
is clear that what we draw is
governed by many factors other
than perceptual ones.
Why is drawing so difficult
for most of us? Why do children
draw the way they do? Why did
good representational
perspective art flower so late
historically? We cannot answer
these questions with any
finality, but I believe that the
psychology of perception can
shed some light on them.
The problems most people
have in drawing are not
primarily ones of motor skill.
After all, most of us can do a
reasonably good job of copying a
triangle, a rectangle, or even a
simple, irregular two-
dimensional shape. The
problems, I believe, are instead
mainly perceptual or cognitive
in nature. Their origins lie in
how we perceive, how we copy
things, how and what we know
about things, and how we
remember things.
