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 : Investigating Visual–Tactile Interactions over Time and Space in Adults with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Daniel POOLE, Auteur ; Emma GOWEN, Auteur ; Paul A. WARREN, Auteur ; Ellen POLIAKOFF, Auteur Article en page(s) : p.3316-3326 Langues : Anglais (eng) Mots-clés : Autism Visual–tactile interactions Multisensory Selective attention Crossmodal congruency task Temporal Spatial Index. décimale : PER Périodiques Résumé : It has been suggested that the sensory symptoms which affect many people with autism spectrum conditions (ASC) may be related to alterations in multisensory processing. Typically, the likelihood of interactions between the senses increases when information is temporally and spatially coincident. We explored visual–tactile interactions in adults with ASC for the first time in two experiments using low-level stimuli. Both participants with ASC and matched neurotypical controls only produced crossmodal interactions to near simultaneous stimuli, suggesting that temporal modulation is unaffected in the adult population. We also provide preliminary evidence that visual–tactile interactions may occur over greater spatial distances in participants with ASC, which merits further exploration.
