Abstract
The category knowledge and receptive language skills of 16 autistic, mentally retarded, and normal children were assessed. The autistic children's knowledge of function, form, and color categories was comparable to that of the mental- age- matched mentally retarded and normal comparison groups. Category knowledge and receptive language were more closely associated for mentally retarded and normal children than for autistic children. The findings indicate that category knowledge is not sufficient for the development of receptive language in autistic children.
