Abstract

This study examined the inability of autistic children to comprehend backward pointing. Backward pointing refers to when an experimenter points in the direction behind a child's back. The comprehension of backward pointing was assessed as a precursor to language. To examine the joint attention function, the experimenter pointed at bubbles because the children showed interest in bubbles. Experiment I involved 53 infants (5 months to 1 year 8 months). Participants in Experiment II were 23 autistic children. The results demonstrated that autistic children with mental age of 13 months and above were as capable of comprehending pointing as were the infants. However unlike the infants, the autistic children could not produce intentional behaviors related to sharing. Deficits in establishing joint attention among the autistic children appeared to be related to the concept of others as intentional agents who possess independent psychological states such as interest in objects.
