Because understanding pictures is a significant aid to readers, this paper explores research on picture interpretation. The paper describes the complexity of the process and states that the ability to interpret pictures seems to proceed from the simple to the complex: from concrete experiences with pictures to the abstract interpretation of in-depth clues. It also discusses the abstract concepts necessary for interpreting pictures (depth perception, perspective, the horizon line, and three dimensionality), and explains how picture interpretation is developed from the exposure to different types of pictures, beginning with simple, direct, clear pictures and progressing to more complex ones that include depth clues, aerial views, and cartoons. The paper lists guidelines for presenting pictures to children and points out that children allowed to draw or paint pictures learn to translate their own and other people's efforts. The paper concludes with ways teachers can help children understand pictures, and explains how a discussion of a drawing can reinforce the child's interest in art, picture interpretation, and English use all at one time.
