Disturbed Interplay Between Mid- and High-Level Vision in ASD? Evidence from a Contour Identification Task with Everyday Objects / Kris EVERS in Journal of Autism and Developmental Disorders, 44-4 (April 2014)

Evidence from a Contour Identification Task with Everyday Objects Type de document : Texte imprimé et/ou numérique Auteurs : Kris EVERS, Auteur ; Sven PANIS, Auteur ; Katrien TORFS, Auteur ; Jean STEYAERT, Auteur ; Ilse NOENS, Auteur ; Johan WAGEMANS, Auteur Année de publication : 2014 Article en page(s) : p.801-815 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD)  Visual perception  Object identification  Weak central coherence theory  Enhanced perceptual functioning hypothesis  Bottom-up versus top-down  Gabor  Local versus global processing Index. décimale : PER Périodiques Résumé : Atypical visual processing in children with autism spectrum disorder (ASD) does not seem to reside in an isolated processing component, such as global or local processing. We therefore developed a paradigm that requires the interaction between different processes—an identification task with Gaborized object outlines—and applied this to two age groups of 6-to-10 and 10-to-14 year old children with and without ASD. Event history analyses demonstrated an identification disadvantage in the ASD group, which remained quite stable during the temporal unfolding of the outline. The typically developing group particularly outperformed the ASD group when more complex contours were shown. Together, our results suggest that the interplay between local and global processes and between bottom-up and top-down processes is disturbed in ASD.
