Multiple Object Tracking in Autism Spectrum Disorders / Kami KOLDEWYN in Journal of Autism and Developmental Disorders, 43-6 (June 2013)
[article]
Titre : Multiple Object Tracking in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Kami KOLDEWYN, Auteur ; Sarah WEIGELT, Auteur ; Nancy KANWISHER, Auteur ; Yuhong V. JIANG, Auteur Article en page(s) : p.1394-1405 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Multiple object tracking Dynamic attention Spatial attention Cognitive development Index. décimale : PER Périodiques Résumé : Difficulties in visual attention are often implicated in autism spectrum disorders (ASD) but it remains unclear which aspects of attention are affected. Here, we used a multiple object tracking (MOT) task to quantitatively characterize dynamic attentional function in children with ASD aged 5–12. While the ASD group performed significantly worse overall, the group difference did not increase with increased object speed. This finding suggests that decreased MOT performance is not due to deficits in dynamic attention but instead to a diminished capacity to select and maintain attention on multiple targets. Further, MOT performance improved from 5 to 10 years in both typical and ASD groups with similar developmental trajectories. These results argue against a specific deficit in dynamic attention in ASD.

Titre : Brief Report: Reduced Grouping Interference in Children with ASD: Evidence from a Multiple Object Tracking Task Type de document : Texte imprimé et/ou numérique Auteurs : Kris EVERS, Auteur ; Lee DE-WIT, Auteur ; Ruth VAN DER HALLEN, Auteur ; Birgitt HAESEN, Auteur ; Jean STEYAERT, Auteur ; Ilse NOENS, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.1779-1787 Langues : Anglais (eng) Mots-clés : Attention Autism spectrum disorder (ASD) Global interference Grouping Multiple object tracking Weak central coherence Index. décimale : PER Périodiques Résumé : This study was inspired by the more locally oriented processing style in autism spectrum disorders (ASD). A modified multiple object tracking (MOT) task was administered to a group of children with and without ASD. Participants not only had to distinguish moving targets from distracters, but they also had to track targets when they were visually grouped to distracters, a manipulation which has a detrimental effect on tracking performance in adults. MOT performance in the ASD group was also affected by grouping, but this effect was significantly reduced. This result highlights how the reduced bias towards more global processing in ASD could influence further stages of cognition by altering the way in which attention selects information for further processing.
