Two tasks were used to assess the processing of whole versus parts of objects in a group of
high-functioning children and adolescents with autism (N=11) and a comparison group of
typically developing peers (N=11) matched for chronological age and IQ. In the first task,
only the children with autism showed a global advantage, and the two groups showed similar
interference between levels. In the second task, the children with autism, despite longer RTs,
showed similar performance to the comparison group with regard to the effect of goodness
on visual parsing. Contrary to expectations based on the central coherence and
hierarchisation deficit theories, these findings indicate intact holistic processing among
persons with autism. The implications of these findings are discussed in relation to
apparently discrepant evidence from other studies.
