How children learn to draw realistic pictures

Children of ages 5 to 17 years were given a real scene to draw from a fixed viewpoint. Their drawings were classified according to the type of drawing system used, and given a score for the number of correct representations of occlusion by overlap. Six classes of drawing system used were identified, and it was found that with increasing age children were able to use an increasingly complex type of system. This development appeared to take place in discrete stages and covered the whole age range tested. Increase in the ability to use overlap as a pictorial device appeared to be continuous; below the age of 9 few children made use of overlap, and rapid learning took place between the ages of 10 and 12. It is argued that the use of these two pictorial devices requires different abilities; and that learning to use a particular type of drawing system does not depend directly on perception or on learning culturally determined stereotypes but in its demands on creative ability closely resembles the acquisition of language.
