Traitement musical dans les troubles du spectre autistique : déficit du traitement global ou surfonctionnement des traitements perceptifs ?

Abstract : This research aimed to explore musical processing in individuals with an autistic spectrum disorder. This question has been tackled by exploring global and local processing in the framework of the two main cognitive theories of autism: i) the weak central coherence theory and ii) the enhanced perceptual processing theory. These two theories postulate a bias toward local processing in autism which originates either from i) a global processing deficit or ii) enhanced perceptual capacities. Through ten studies, we confronted these two theories by manipulating global and local processing of music. We also explored auditory perception in autistic people and its impact on higher musical processing. Globally, our research highlights a greater implication of perceptual processes in musical processing, giving support to the enhanced perceptual processing theory. In addition, some of our results point to a central cognitive mechanism in autism: the mechanism of veridical mapping.
