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.

Multiple Object Tracking Reveals Object-Based Grouping Interference in Children with ASD / Ruth VAN DER HALLEN in Journal of Autism and Developmental Disorders, 48-4 (April 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-4 (April 2018) . - p.1341-1349 Titre : Multiple Object Tracking Reveals Object-Based Grouping Interference in Children with ASD Type de document : texte imprimé Auteurs : Ruth VAN DER HALLEN, Auteur ; Kris EVERS, Auteur ; Lee DE-WIT, Auteur ; Jean STEYAERT, Auteur ; Ilse NOENS, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.1341-1349 Langues : Anglais (eng) Mots-clés : Attention  Autism spectrum disorder (ASD)  Grouping  Interference  Multiple object tracking (MOT)  Vision research Index. décimale : PER Périodiques Résumé : The multiple object tracking (MOT) paradigm has proven its value in targeting a number of aspects of visual cognition. This study used MOT to investigate the effect of object-based grouping, both in children with and without autism spectrum disorder (ASD). A modified MOT task was administered to both groups, who had to track and distinguish four targets that moved randomly amongst four distracters, irrespective of the grouping condition. No group difference was revealed between children with and without ASD: both showed adequate MOT abilities and a similar amount of grouping interference. Implications of the current result are considered for previous MOT studies, the developmental trajectory of perceptual grouping, and the idea of heightened sensitivity to task characteristics in ASD.

Superior Disembedding in Children with ASD: New Tests Using Abstract, Meaningful, and 3D Contexts / Ruth VAN DER HALLEN in Journal of Autism and Developmental Disorders, 48-7 (July 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-7 (July 2018) . - p.2478-2489 Titre : Superior Disembedding in Children with ASD: New Tests Using Abstract, Meaningful, and 3D Contexts Type de document : texte imprimé Auteurs : Ruth VAN DER HALLEN, Auteur ; Rebecca CHAMBERLAIN, Auteur ; Lee DE-WIT, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.2478-2489 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD)  Disembedding  Eft  L-eft  Perceptual organization Index. décimale : PER Périodiques Résumé : Since its initial development, the embedded figures test (EFT) has been used extensively to measure local-global perceptual style. However, little is known about the perceptual factors that influence target detection. The current study aimed to investigate disembedding in children with and without ASD, aged 8-15 years, using the newly developed, stimulus-controlled L-EFT, M-EFT and D-EFT. Firstly, results revealed superior disembedding for children with ASD, irrespective of the type of target or embedding context, although the ASD group took more time in both the M-EFT and D-EFT. Secondly, the number of target lines continuing into the context proved more of a hindrance for the controls. Taken together, these findings provide strong evidence to support the notion of superior disembedding in ASD.
