In an effort to resolve this question, we tested a large group of children on both a free-choice task and an instructed task using hierarchical local–global stimuli. We find that although children with autism showed a reduced preference to report global properties of a stimulus when given a choice, their ability to process global properties when instructed to do so is unimpaired. These findings support prior claims that people with ASD show a disinclination, not a disability, in global processing, and highlight the broader question of whether other characteristics of autism may also reflect disinclinations rather than disabilities.

Multiple Object Tracking in Autism Spectrum Disorders / Kami KOLDEWYN in Journal of Autism and Developmental Disorders, 43-6 (June 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-6 (June 2013) . - p.1394-1405 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.
