L'autisme : une pathologie du codage temporel ?

Abstract : In this article, we present the final report of a cooperative project that was conducted by a group of clinicians and three groups of researchers belonging to CNRS or University. The aim of this project was to test a novel unifiying hypothesis in autism : are the communicative and interactive disorders in autism correlated with a temporal processing impairment of sensory and motor events. Autistic children and adolescents were tested in three experimental tasks aimed at testing i) motion vision, ii) phonems categorial perception and iii) motor anticipation. Results indicate that performance of autistic subjects is limited comparatively to that of normal control subjects in each task, which suppose that they have difficulties in processing sensory inputs and producing motor outputs online. These difficulties could account for their communicative and interactive impairments. Neurophysiological explanations involving cerebellum are proposed to explain this temporal processing deficit. Reeducational pathways using slowed down visual motion and speech flow are also suggested.
