Brief Report: Reduced Grouping Interference in Children with ASD: Evidence from a Multiple Object Tracking Task / Kris EVERS in Journal of Autism and Developmental Disorders, 44-7 (July 2014)
[article]
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.

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.

Titre : Typical perceptual organization in autism: Perceptual grouping and spatial distortion Type de document : Texte imprimé et/ou numérique Auteurs : R. AVRAAM, Auteur ; N. BINUR, Auteur ; B. S. HADAD, Auteur Article en page(s) : p.1623-1635 Langues : Anglais (eng) Mots-clés : autism gestalt principles grouping implicit local global processing perceptual organization Index. décimale : PER Périodiques Résumé : The extensive literature on global-local processing in people with autism spectrum disorder (ASD) has recently shifted from arguing for a processing impairment among those with ASD to positing an attenuated preference for global processing. One suggestion is that the fast extraction of the global gist is less efficient in ASD, in contrast to the superior attention-driven processing of local elements. To examine this claim of attenuated global processing, the present study tested how perceptual grouping affected the global organization of visual scenes, specifically testing the claim of less mandatory, more optional global processing in ASD. Participants judged the distance between grouped and ungrouped elements in displays in which illusory distortions were inherent in configurations exemplifying the Gestalt principles of organization. Results from six experiments manipulating different Gestalt cues showed a consistent pattern, indicating that for individuals with ASD, as for typically developed (TD) individuals, grouping processes are organizational in nature, incorporating the grouping of related elements while parsing these from other unrelated elements. This parsing is accompanied by distortions in the spatial relationships perceived in the visual scene. ASD participants exhibited an overall larger tendency to overestimate the distances, but they also demonstrated typical perceptual organization processes that were robust and mandatory and, as in neurotypicals, affected the perception of the whole scene. Autism Res 2019. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: It is known that individuals with autism spectrum disorder (ASD) perceive the world in a different way than their typically developed (TD) peers. While TD individuals exhibit strong bias toward processing the global structure of visual scenes, individuals with ASD exhibit enhanced perception of the local elements. We showed that when the local and global levels are not competing, individuals with autism demonstrate robust global organization that operates even when not directly instructed.

Yet, methodological differences between studies have led to inconsistent findings. To distinguish between accounts based on local bias or global deficit, we present a simple task that has previously revealed dissociable local/global impairments in neuropsychological patients. Autistic and typical children copied corner elements, arranged in a square configuration. Grouping cues were manipulated to test whether global properties affected the accuracy of reproduction. All children were similarly affected by these manipulations. There was no group difference in the reproduction of local elements, although global accuracy was negatively related to better local processing for autistic children. These data speak against influential theories of visuospatial differences in autism.
