Perception et imitation du mouvement dans l'autisme : une question de temps

Abstract : An increasing amount of studies demonstrated the existence of biological motion integration deficit in individuals with autism, especially when velocity of movement is high. This type of movements (such as facial and body gestures) is intrinsically involved in social interactions: a rapid visual-motion processing deficit could therefore account for their verbal and non verbal comprehension and social interaction disorders. Previous studies showed that the speed of presentation of facial expressions to children with autism may influence their performance in recognition of these facial expressions, i.e., a slowed down presentation enhances their performance, particularly in those having the more severe autistic disorders. In the present study, we aimed at extending these findings to the field of imitation, i.e., to assess the influence of the speed of presentation of various gestures on the imitative abilities of children and adolescents with autism and normal control subjects. These gestures are meaningless, presented on a computer screen at normal and slowed down speeds by the means of a software especially dedicated to this research. Results show that autistic individuals, especially the more affected ones and those having the lower verbal comprehension level, imitate more poorly than their controls. More importantly, slow dynamic presentations enhance the performance in imitation of the autistic children. These findings may open new lines of interventions in the domain of perceptive and communicative reeducation in autistic individuals.
