Abstract
A comparison of the toy play behavior and use of body of 30 autistic and 30 normal children between the ages of 2 and 7 was made by use of a maternal questionnaire. The questionnaire was designed to yield a descriptive profile of age-appropriate play behavior and ritualistic behavior generally found to be characteristic of the autistic child. Exact probability tests on each of the 47 items of the questionnaire indicated significant differences (p < .05) between groups, the normal Ss demonstrating more age-appropriate play behavior and the autistic more ritualistic behavior. Validity of the questionnaire was examined by comparing items from the questionnaire to similarly defined items in a structured observation study of autistic, normal, and retarded children. 14 autistic Ss were available for both studies. Consistency in toy-play behavior of autistic children was indicated as measured by the two techniques. Differences in toy-play behavior of normal and autistic samples were definitely indicated; a questionnaire technique gave high agreement with observation, providing a useful and efficient method for measuring toy-play behavior; further refinement of the questionnaire seems appropriate.
