Ultra-Rapid Categorization of Meaningful Real-Life Scenes in Adults With and Without ASD / Steven VANMARCKE in Journal of Autism and Developmental Disorders, 46-2 (February 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-2 (February 2016) . - p.450-466 Titre : Ultra-Rapid Categorization of Meaningful Real-Life Scenes in Adults With and Without ASD Type de document : Texte imprimé et/ou numérique Auteurs : Steven VANMARCKE, Auteur ; Ruth HALLEN, Auteur ; Kris EVERS, Auteur ; Ilse NOENS, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur Année de publication : 2016 Article en page(s) : p.450-466 Langues : Anglais (eng) Mots-clés : Catégorisation  Autism spectrum disorder  Vision research  Ultra-rapid categorization  Theory of mind  Reverse hierarchy theory Index. décimale : PER Périodiques Résumé : In comparison to typically developing (TD) individuals, people with autism spectrum disorder (ASD) appear to be worse in the fast extraction of the global meaning of a situation or picture. Ultra-rapid categorization [paradigm developed by Thorpe et al. (Nature 381:520–522, 1996)] involves such global information processing. We therefore tested a group of adults with and without ASD, without intellectual disability, on a set of ultra-rapid categorization tasks. Individuals with ASD performed equally well as TD individuals except when the task required the categorization of social interactions. These results argue against a general deficit in ultra-rapid gist perception in people with ASD, while suggesting a more specific problem with the fast processing of information about social relations.

Gist perception in adolescents with and without ASD: Ultra-rapid categorization of meaningful real-life scenes / Steven VANMARCKE in Research in Autism Spectrum Disorders, 29-30 (September–October 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 29-30 (September–October 2016) . - p.30-47 Titre : Gist perception in adolescents with and without ASD: Ultra-rapid categorization of meaningful real-life scenes Type de document : Texte imprimé et/ou numérique Auteurs : Steven VANMARCKE, Auteur ; Lotte VAN ESCH, Auteur ; Ruth VAN DER HALLEN, Auteur ; Kris EVERS, Auteur ; Ilse NOENS, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.30-47 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Vision research  Ultra-rapid categorization  Theory of mind  Reverse hierarchy theory  Developmental effects Index. décimale : PER Périodiques Résumé : Abstract Previous research has suggested the presence of a reduced preference to report and spontaneously interpret the global properties of a scene picture in adults with Autism Spectrum Disorder (ASD). Contrary to what is seen in typically developing (TD) participants, gist perception in ASD seems to occur mostly in a more explicit manner with focused attention. The current study used a set of non-social and social ultra-rapid categorization tasks to investigate gist perception in adolescents with and without ASD. When we instructed the participants to rapidly identify briefly presented object or scene information, we found that adolescents with ASD performed worse than TD participants. These findings complemented our previous study on ultra-rapid categorization in adults with or without ASD, in which no group-level differences in gist perception were observed. When categorization specifically entailed the fast processing of socially salient information, both adolescents and adults with ASD performed worse than TD participants. The combination of these results suggests an age-dependent improvement in general categorization ability but more long-lasting difficulties in rapid social categorization in individuals with ASD. We suggest that the poorer general performance of adolescents with ASD results from a less efficient rapid processing of global semantic structure.
