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)

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.

Moreover, we examined whether indicators of parental well-being promoted resilience of children with ASD. Results showed that the mean change in problems did not differ between children with and without ASD. Importantly, some children showed an increase in problems, while others showed resilience. Parental well-being indicators were not related to resilience among children with ASD. The interindividual variability in responses, particularly among children with ASD, highlights the need for personalized support.

Ensemble perception in autism spectrum disorder: Member-identification versus mean-discrimination / Ruth VAN DER HALLEN in Autism Research, 10-7 (July 2017)

While most studies on ensemble perception investigate this perceptual mechanism in typically developing (TD) adults, more recently, researchers studying perceptual organization in individuals with autism spectrum disorder (ASD) have turned their attention toward ensemble perception. The current study is the first to investigate the use of ensemble perception for size in children with and without ASD (N?=?42, 8–16 years). We administered a pair of tasks pioneered by Ariely [2001] evaluating both member-identification and mean-discrimination. In addition, we varied the distribution types of our sets to allow a more detailed evaluation of task performance. Results show that, overall, both groups performed similarly in the member-identification task, a test of “local perception,” and similarly in the mean identification task, a test of “gist perception.” However, in both tasks performance of the TD group was affected more strongly by the degree of stimulus variability in the set, than performance of the ASD group. These findings indicate that both TD children and children with ASD use ensemble statistics to represent a set of similar items, illustrating the fundamental nature of ensemble coding in visual perception. Differences in sensitivity to stimulus variability between both groups are discussed in relation to recent theories of information processing in ASD (e.g., increased sampling, decreased priors, increased precision).

Gist perception in adolescents with and without ASD: Ultra-rapid categorization of meaningful real-life scenes / Steven VANMARCKE in Research in Autism Spectrum Disorders, 29-30 (September–October 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 29-30 (September–October 2016) . - p.30-47 Titre : Gist perception in adolescents with and without ASD: Ultra-rapid categorization of meaningful real-life scenes Type de document : Texte imprimé et/ou numérique Auteurs : Steven VANMARCKE, Auteur ; Lotte VAN ESCH, Auteur ; Ruth VAN DER HALLEN, Auteur ; Kris EVERS, Auteur ; Ilse NOENS, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.30-47 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Vision research  Ultra-rapid categorization  Theory of mind  Reverse hierarchy theory  Developmental effects Index. décimale : PER Périodiques Résumé : Abstract Previous research has suggested the presence of a reduced preference to report and spontaneously interpret the global properties of a scene picture in adults with Autism Spectrum Disorder (ASD). Contrary to what is seen in typically developing (TD) participants, gist perception in ASD seems to occur mostly in a more explicit manner with focused attention. The current study used a set of non-social and social ultra-rapid categorization tasks to investigate gist perception in adolescents with and without ASD. When we instructed the participants to rapidly identify briefly presented object or scene information, we found that adolescents with ASD performed worse than TD participants. These findings complemented our previous study on ultra-rapid categorization in adults with or without ASD, in which no group-level differences in gist perception were observed. When categorization specifically entailed the fast processing of socially salient information, both adolescents and adults with ASD performed worse than TD participants. The combination of these results suggests an age-dependent improvement in general categorization ability but more long-lasting difficulties in rapid social categorization in individuals with ASD. We suggest that the poorer general performance of adolescents with ASD results from a less efficient rapid processing of global semantic structure.

Hierarchical Letters in ASD: High Stimulus Variability Under Different Attentional Modes / Ruth VAN DER HALLEN in Journal of Autism and Developmental Disorders, 47-6 (June 2017)

The current study focused on stimulus variability and locational uncertainty, while using different attentional modes. Two groups of 44 children with and without ASD completed a divided attention task as well as a global and local selective attention task. The results revealed global-to-local and local-to-global interference in ASD, to the same extent as in the TD group. Both groups struggled with the same type of stimuli (i.e., ignoring the global level information) and performed similar in all three tasks. Future studies on (visual) information processing in ASD should pursue the impact of stimulus noise and trial-by-trial uncertainty further.
