In this discussion, I have
suggested several reasons why
drawing or painting is difficult
and why the productions of
children and of artists of
antiquity contain certain kinds
of "errors." However, I must add
an important disclaimer.
Drawings or paintings that are
poor representations of objects
and scenes by our standards
and expectations of realism
need not be the result of the
perceptual or cognitive
limitations I have suggested;
rather, they may be the result
of an intention or convention
to draw in a particular way.
Perhaps the Egyptians drew
pictures of people the way they
did because they believed that
side views of faces and feet and
frontal views of torsos were the
most informative about the
human body. The lack of
perspective in painting does
not necessarily mean the
absence of the ability to use it.
The realistic aim is not the
only aim in art, and it only
appears here and there in
different cultures and at
different times in history.
Similarly, children are not
always concerned with making
realistic drawings but instead
may be motivated to express
themselves in form and color. It
would be absurd to infer from
PicassoΓÇÖs more abstract
paintings that he could not
draw realistically when some of
his other work shows how great
a master of realistic portrayal
he was when he chose to be. If
one did not know about the
realistic paintings, however,
one might make just that wrong
inference from the abstract
ones.
In this and the preceding
chapters, I have necessarily
referred often to object and
shape (or form) perception.
From this one might draw the
conclusion that such
perception is based solely on
the reception of the shape of
the objectΓÇÖs image on the retina
as given by its contours. As will
be seen in the next chapter,
nothing could be farther from
the truth. Even so simple a
perception as that of a single
two-dimensional shape poses
many difficult problems.
