The second feature to note is dimension. Normal children tend to make two-dimensional representations of objects in a canonical' format and then add any salient features. In other words they have a basic representational format for a person or a house or a ship or whatever and then add on particular details that specify that particular view of the person, house, or ship. It is only much later that a child is prepared to deform its canonical representation. Most people indeed continue to make canonical representations throughout adult life. The anomalous droughts man on the other hand is quite prepared to draw from a single viewpoint and does not seem concerned at all about the ambiguity that might result from something that is assumed to be of concern to the normal child artist.
