The perception of social and mechanical causality in young children with ASD / Elizabeth RAY in Research in Autism Spectrum Disorders, 1-3 (July/September 2007)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 1-3 (July/September 2007) . - p.266-280 Titre : The perception of social and mechanical causality in young children with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth RAY, Auteur ; Anne SCHLOTTMANN, Auteur Année de publication : 2007 Article en page(s) : p.266-280 Langues : Anglais (eng) Mots-clés : Autism Perceptual-causality ASD Index. décimale : PER Périodiques Résumé : This study investigated perceptual causality in launch and reaction events in children with ASD (CA = 8.4, VMA = 5.1) and mental age matched controls with typical development and learning difficulties. This is of interest because difficulties with global processing in autism suggest that individuals with ASD may not ‘see’ causal Gestalts in general, and specific difficulties with reaction perception could be related to difficulties with TOM. Participants matched pictures depicting mechanical and psychological cause and non-causality to computer animated launch and reaction events and delayed control events. Children with ASD showed the typical response to reaction events, matching them with the picture for psychological cause, but they were impaired in launch perception compared to control participants. We discuss the possibility that event duration may be the critical difference between the causal events. The information allowing identification of a reaction is conveyed over a longer time frame (600 ms here) than in launching (21 ms here). This may allow for the deployment of global processes and/or attentional shifts in reaction, but not launch perception.

Unimpaired Perception of Social and Physical Causality, but Impaired Perception of Animacy in High Functioning Children with Autism / Sara CONGIU in Journal of Autism and Developmental Disorders, 40-1 (January 2010)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 40-1 (January 2010) . - p.39-53 Titre : Unimpaired Perception of Social and Physical Causality, but Impaired Perception of Animacy in High Functioning Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Sara CONGIU, Auteur ; Elizabeth RAY, Auteur ; Anne SCHLOTTMANN, Auteur Année de publication : 2010 Article en page(s) : p.39-53 Langues : Anglais (eng) Mots-clés : High-functioning-autism Perceptual-causality Perceptual-animacy Index. décimale : PER Périodiques Résumé : We investigated perception of social and physical causality and animacy in simple motion events, for high-functioning children with autism (CA = 13, VMA = 9.6). Children matched 14 different animations to pictures showing physical, social or non-causality. In contrast to previous work, children with autism performed at a high level similar to VMA-matched controls, recognizing physical causality in launch and social causality in reaction events. The launch deficit previously found in younger children with autism, possibly related to attentional/verbal difficulties, is apparently overcome with age. Some events involved squares moving non-rigidly, like animals. Children with autism had difficulties recognizing this, extending the biological motion literature. However, animacy prompts amplified their attributions of social causality. Thus children with autism may overcome their animacy perception deficit strategically.
