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.

Titre : Cognitive flexibility in autism spectrum disorder: Explaining the inconsistencies? Type de document : Texte imprimé et/ou numérique Auteurs : Lien VAN EYLEN, Auteur ; Bart BOETS, Auteur ; Jean STEYAERT, Auteur ; Kris EVERS, Auteur ; Johan WAGEMANS, Auteur ; Ilse L.J. NOENS, Auteur Année de publication : 2011 Article en page(s) : p.1390-1401 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Cognitive flexibility Task-switching Wisconsin Card Sorting Task Disengagement Task instructions Index. décimale : PER Périodiques Résumé : The Wisconsin Card Sorting Task (WCST) is the only cognitive flexibility task that has consistently shown deficits in individuals with an autism spectrum disorder (ASD). As this is the only task characterized by limited explicit task instructions and a high degree of disengagement required to perform the switch, we hypothesized that cognitive flexibility deficits of individuals with ASD might only become apparent in situations fulfilling these requirements. However, the WCST involves various additional cognitive processes besides switching, making it uncertain whether difficulties are indeed due to cognitive flexibility impairments. The aim of this study was to investigate whether individuals with ASD show cognitive flexibility impairments on a more controlled task-switching variant of the WCST, still fulfilling both requirements. We therefore developed such a task and administered it to 40 high-functioning children with ASD and 40 age- and IQ- matched typically developing controls. As predicted, individuals with ASD made more perseveration errors and had a significantly higher switch cost than typically developing controls, but they performed equally well on the control measures.

Titre : Combining strengths and weaknesses in visual perception of children with an autism spectrum disorder: Perceptual matching of facial expressions Type de document : Texte imprimé et/ou numérique Auteurs : Kris EVERS, Auteur ; Ilse L.J. NOENS, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur Année de publication : 2011 Article en page(s) : p.1327-1342 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD) Matching Facial emotional expressions Compensation strategy Weak central coherence Enhanced perceptual functioning Index. décimale : PER Périodiques Résumé : Background
Children with an autism spectrum disorder (ASD) are known to have an atypical visual perception, with deficits in automatic Gestalt formation and an enhanced processing of visual details. In addition, they are sometimes found to have difficulties in emotion processing.
Methods
In three experiments, we investigated whether 7-to-11-year old children with ASD were showing superiorities or deficits in matching tasks that required focusing on faces with an emotional expression. Throughout these experiments, we increased the complexity of the stimuli and tasks demands.
Results and conclusions
In matching faces with emotional expressions, children with ASD were not able to show superior processing of details in any of the three experiments. They were able to compensate their inferior processing of emotions in some of the experiments (e.g., by using a slower, more sequential processing style). However, when stimulus complexity (e.g., dynamic facial expressions) or task demands (e.g., extracting and remembering the relevant stimulus dimension) increased, they were no longer able to do so, and they did show performance deficits.En ligne : http://dx.doi.org/10.1016/j.rasd.2011.01.004 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=125

Evidence from a Contour Identification Task with Everyday Objects Type de document : Texte imprimé et/ou numérique Auteurs : Kris EVERS, Auteur ; Sven PANIS, Auteur ; Katrien TORFS, Auteur ; Jean STEYAERT, Auteur ; Ilse NOENS, Auteur ; Johan WAGEMANS, Auteur Année de publication : 2014 Article en page(s) : p.801-815 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD) Visual perception Object identification Weak central coherence theory Enhanced perceptual functioning hypothesis Bottom-up versus top-down Gabor Local versus global processing Index. décimale : PER Périodiques Résumé : Atypical visual processing in children with autism spectrum disorder (ASD) does not seem to reside in an isolated processing component, such as global or local processing. We therefore developed a paradigm that requires the interaction between different processes—an identification task with Gaborized object outlines—and applied this to two age groups of 6-to-10 and 10-to-14 year old children with and without ASD. Event history analyses demonstrated an identification disadvantage in the ASD group, which remained quite stable during the temporal unfolding of the outline. The typically developing group particularly outperformed the ASD group when more complex contours were shown. Together, our results suggest that the interplay between local and global processes and between bottom-up and top-down processes is disturbed in ASD.
