Fragile Spectral and Temporal Auditory Processing in Adolescents with Autism Spectrum Disorder and Early Language Delay / Bart BOETS in Journal of Autism and Developmental Disorders, 45-6 (June 2015)
[article]
Titre : Fragile Spectral and Temporal Auditory Processing in Adolescents with Autism Spectrum Disorder and Early Language Delay Type de document : Texte imprimé et/ou numérique Auteurs : Bart BOETS, Auteur ; Judith VERHOEVEN, Auteur ; Jan WOUTERS, Auteur ; Jean STEYAERT, Auteur Article en page(s) : p.1845-1857 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Auditory processing Hemispheric lateralization Spectral Temporal Pitch Index. décimale : PER Périodiques Résumé : We investigated low-level auditory spectral and temporal processing in adolescents with autism spectrum disorder (ASD) and early language delay compared to matched typically developing controls. Auditory measures were designed to target right versus left auditory cortex processing (i.e. frequency discrimination and slow amplitude modulation (AM) detection versus gap-in-noise detection and faster AM detection), and to pinpoint the task and stimulus characteristics underlying putative superior spectral processing in ASD. We observed impaired frequency discrimination in the ASD group and suggestive evidence of poorer temporal resolution as indexed by gap-in-noise detection thresholds. These findings question the evidence of enhanced spectral sensitivity in ASD and do not support the hypothesis of superior right and inferior left hemispheric auditory processing in ASD.

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.

Titre : In the Eye of the Beholder: Rapid Visual Perception of Real-Life Scenes by Young Adults with and Without ASD Type de document : Texte imprimé et/ou numérique Auteurs : Steven VANMARCKE, Auteur ; Caitlin MULLIN, Auteur ; Ruth VAN DER HALLEN, Auteur ; Kris EVERS, Auteur ; Ilse NOENS, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.2635-2652 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Rapid visual perception Local/global processing Open-encoding Semantic processing Index. décimale : PER Périodiques Résumé : Typically developing (TD) adults are able to extract global information from natural images and to categorize them within a single glance. This study aimed at extending these findings to individuals with autism spectrum disorder (ASD) using a free description open-encoding paradigm. Participants were asked to freely describe what they saw when looking at briefly presented real-life photographs. Our results show subtle but consistent group-level differences. More specifically, individuals with ASD spontaneously reported the presence of people in the display less frequently than TD participants, and they grasped the gist of the scene less well. These findings argue for a less efficient rapid feedforward processing of global semantic aspects and a less spontaneous interpretation of socially salient information in ASD.

[article]
Titre : No Differences in Emotion Recognition Strategies in Children with Autism Spectrum Disorder: Evidence from Hybrid Faces Type de document : Texte imprimé et/ou numérique Auteurs : Kris EVERS, Auteur ; Inneke KERKHOF, Auteur ; Jean STEYAERT, Auteur ; Ilse NOENS, Auteur ; Johan WAGEMANS, Auteur Année de publication : 2014 Article en page(s) : 8 p. Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Emotion recognition problems are frequently reported in individuals with an autism spectrum disorder (ASD). However, this research area is characterized by inconsistent findings, with atypical emotion processing strategies possibly contributing to existing contradictions. In addition, an attenuated saliency of the eyes region is often demonstrated in ASD during face identity processing. We wanted to compare reliance on mouth versus eyes information in children with and without ASD, using hybrid facial expressions. A group of six-to-eight-year-old boys with ASD and an age- and intelligence-matched typically developing (TD) group without intellectual disability performed an emotion labelling task with hybrid facial expressions. Five static expressions were used: one neutral expression and four emotional expressions, namely, anger, fear, happiness, and sadness. Hybrid faces were created, consisting of an emotional face half (upper or lower face region) with the other face half showing a neutral expression. Results showed no emotion recognition problem in ASD. Moreover, we provided evidence for the existence of top- and bottom-emotions in children: correct identification of expressions mainly depends on information in the eyes (so-called top-emotions: happiness) or in the mouth region (so-called bottom-emotions: sadness, anger, and fear). No stronger reliance on mouth information was found in children with ASD.

Titre : Oxytocin receptor gene (OXTR) DNA methylation is associated with autism and related social traits – A systematic review Type de document : Texte imprimé et/ou numérique Auteurs : Matthijs MOERKERKE, Auteur ; Marie-Laure BONTE, Auteur ; Nicky DANIELS, Auteur ; Viktoria CHUBAR, Auteur ; Kaat ALAERTS, Auteur ; Jean STEYAERT, Auteur ; Bart BOETS, Auteur Article en page(s) : 101785 Langues : Anglais (eng) Mots-clés : Oxytocin receptor gene Epigenetics DNA methylation Autism Social behaviour Index. décimale : PER Périodiques Résumé : There is emerging evidence implicating oxytocin receptor gene (OXTR) DNA methylation (DNAm) in social behaviour. This review investigated its association with autism spectrum disorder (ASD) characteristics and related social dimensions, both in individuals with and without ASD. Twelve articles investigating OXTR DNAm in relation to ASD, social perception/cognition and social anxiety were included. We found that hypermethylation is associated with (i) higher quantitative autism traits in adults, reflecting a higher incidence of autism characteristics, (ii) increased brain activity while performing social tasks (indicating a higher need for resources) and (iii) decreased functional connectivity. (iv) Contradictory, hypomethylation was found to be present in children (especially boys) with ASD and was also associated with more social anxiety. While the included studies displayed a large variability, for example in terms of population characteristics, analysed OXTR DNAm regions, and adopted scales/questionnaires, an initial developmental pattern of results emerged, suggesting an association between hypermethylation of OXTR and autism traits in adults. Nonetheless, future studies are warranted to corroborate these initial conclusions.
