Brief Report: Coherent Motion Processing in Autism: Is Dot Lifetime an Important Parameter? / Catherine MANNING in Journal of Autism and Developmental Disorders, 45-7 (July 2015)
[article]
Titre : Brief Report: Coherent Motion Processing in Autism: Is Dot Lifetime an Important Parameter? Type de document : Texte imprimé et/ou numérique Auteurs : Catherine MANNING, Auteur ; Tony CHARMAN, Auteur ; Elizabeth PELLICANO, Auteur Année de publication : 2015 Article en page(s) : p.2252-2258 Langues : Anglais (eng) Mots-clés : Vision Motion processing Stimulus parameters Temporal integration Correspondence noise Index. décimale : PER Périodiques Résumé : Contrasting reports of reduced and intact sensitivity to coherent motion in autistic individuals may be attributable to stimulus parameters. Here, we investigated whether dot lifetime contributes to elevated thresholds in children with autism. We presented a standard motion coherence task to 31 children with autism and 31 typical children, with both limited and unlimited lifetime conditions. Overall, children had higher thresholds in the limited lifetime condition than in the unlimited lifetime condition. However, children with autism were affected by this manipulation to the same extent as typical children and were equally sensitive to coherent motion. Our results suggest that dot lifetime is not a critical stimulus parameter and speak against pervasive difficulties in coherent motion perception in children with autism.
