Deficits in gestural joint-attention behaviors are a prominent feature of young autistic children. Attempts to explain these deficits have called upon the metarepresentational deficit hypothesis (Baron-Cohen, 1988; Leslie & Frith, 1988). However, developmental research suggests that joint-attention skills emerge prior to the cognitive capacity for metarepresentation. Thus, the metarepresentational hypothesis does not appear to provide a parsimonious explanation of autistic joint-attention deficits. An alternative model is proposed that attempts to explain these deficits in terms of the combined negative impact of developmental disturbances in affective, as well as cognitive, processes.
