Brief Report: Altered Horizontal Binding of Single Dots to Coherent Motion in Autism / Nicole DAVID in Journal of Autism and Developmental Disorders, 40-12 (December 2010)
[article]
Titre : Brief Report: Altered Horizontal Binding of Single Dots to Coherent Motion in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Nicole DAVID, Auteur ; Michael ROSE, Auteur ; Till R. SCHNEIDER, Auteur ; Kai VOGELEY, Auteur ; Andreas K. ENGEL, Auteur Année de publication : 2010 Article en page(s) : p.1549-1551 Langues : Anglais (eng) Mots-clés : Apparent motion Bistable perception Binding Interhemispheric communication High-functioning autism Index. décimale : PER Périodiques Résumé : Individuals with autism often show a fragmented way of perceiving their environment, suggesting a disorder of information integration, possibly due to disrupted communication between brain areas. We investigated thirteen individuals with high-functioning autism (HFA) and thirteen healthy controls using the metastable motion quartet, a stimulus consisting of two dots alternately presented at four locations of a hypothetical square, thereby inducing an apparent motion percept. This percept is vertical or horizontal, the latter requiring binding of motion signals across cerebral hemispheres. Decreasing the horizontal distance between dots could facilitate horizontal percepts. We found evidence for altered horizontal binding in HFA: Individuals with HFA needed stronger facilitation to experience horizontal motion. These data are interpreted in light of reduced cross-hemispheric communication.

Titre : Impairments in multisensory processing are not universal to the autism spectrum: no evidence for crossmodal priming deficits in Asperger syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Nicole DAVID, Auteur ; Till R. SCHNEIDER, Auteur ; Kai VOGELEY, Auteur ; Andreas K. ENGEL, Auteur Année de publication : 2011 Article en page(s) : p.383-388 Langues : Anglais (eng) Mots-clés : Asperger syndrome high-functioning autism multisensory processing crossmodal priming local processing Index. décimale : PER Périodiques Résumé : Individuals suffering from autism spectrum disorders (ASD) often show a tendency for detail- or feature-based perception (also referred to as “local processing bias”) instead of more holistic stimulus processing typical for unaffected people. This local processing bias has been demonstrated for the visual and auditory domains and there is evidence that multisensory processing may also be affected in ASD. Most multisensory processing paradigms used social-communicative stimuli, such as human speech or faces, probing the processing of simultaneously occuring sensory signals. Multisensory processing, however, is not limited to simultaneous stimulation. In this study, we investigated whether multisensory processing deficits in ASD persist when semantically complex but nonsocial stimuli are presented in succession. Fifteen adult individuals with Asperger syndrome and 15 control persons participated in a visual-audio priming task, which required the classification of sounds that were either primed by semantically congruent or incongruent preceding pictures of objects. As expected, performance on congruent trials was faster and more accurate compared with incongruent trials (crossmodal priming effect). The Asperger group, however, did not differ significantly from the control group. Our results do not support a general multisensory processing deficit, which is universal to the entire autism spectrum.
