Global Motion Perception in Autism Spectrum Disorder: A Meta-Analysis / R. VAN DER HALLEN in Journal of Autism and Developmental Disorders, 49-12 (December 2019)

WAGEMANS, Auteur Article en page(s) : p.4901-4918 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD)  Biological motion  Coherent motion  Meta-analysis  Motion perception Index. décimale : PER Périodiques Résumé : Visual perception in individuals with autism spectrum disorder (ASD) is often debated in terms of enhanced local and impaired global perception. Deficits in global motion perception seem to support this characterization, although the evidence is inconsistent. We conducted a large meta-analysis on global motion, combining 48 articles on biological and coherent motion. Results provide evidence for a small global motion processing deficit in individuals with ASD compared to controls in both biological and coherent motion. This deficit appears to be present independent of the paradigm, task, dependent variable, age or IQ of the groups. Results indicate that individuals with ASD are less sensitive to these types of global motion, although the difference in neural mechanisms underlying this behavioral difference remains unclear.

Multiple Object Tracking Reveals Object-Based Grouping Interference in Children with ASD / R. 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 et/ou numérique Auteurs : R. VAN DER HALLEN, Auteur ; K. EVERS, Auteur ; L. DE-WIT, Auteur ; J. STEYAERT, Auteur ; I. NOENS, Auteur ; J. 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 / R. VAN DER HALLEN in Journal of Autism and Developmental Disorders, 48-7 (July 2018)

VAN DER HALLEN, Auteur ; R. CHAMBERLAIN, Auteur ; L. DE-WIT, Auteur ; J. 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.
