Intersubjectivity and Understanding Motor Intentions: Evidence From Autism and Williams Syndrome

The main aim of this study was to better our understanding of what and why comprehension in ASD by comparing performance of younger children with low-functioning autism, children with WS and children with TD matched for mental age on a behavioral task. This would allow to evaluate whether impairment in motor intention understanding during the observation of simple motor acts: (a) proved to be different in ASD and in WS on comparable groups; (b) would present in ASD a similar developmental pattern to the one found in previous studies.
