Atypical sound discrimination in children with ASD as indicated by cortical ERPs / Aurélie BIDET-CAULET in Journal of Neurodevelopmental Disorders, 9-1 (December 2017)
[article]
Titre : Atypical sound discrimination in children with ASD as indicated by cortical ERPs Type de document : Texte imprimé et/ou numérique Auteurs : Aurélie BIDET-CAULET, Auteur ; Marianne LATINUS, Auteur ; S. ROUX, Auteur ; J. MALVY, Auteur ; Frédérique BONNET-BRILHAULT, Auteur ; N. BRUNEAU, Auteur Article en page(s) : p.13 Langues : Anglais (eng) Mots-clés : Auditory Autism Development Ftpv Speech Voice Index. décimale : PER Périodiques Résumé : BACKGROUND: Individuals with autism spectrum disorder (ASD) show a relative indifference to the human voice. Accordingly, and contrarily to their typically developed peers, adults with autism do not show a preferential response to voices in the superior temporal sulcus; this lack of voice-specific response was previously linked to atypical processing of voices. In electroencephalography, a slow event-related potential (ERP) called the fronto-temporal positivity to voice (FTPV) is larger for vocal than for non-vocal sounds, resulting in a voice-sensitive response over right fronto-temporal sites. Here, we investigated the neurophysiological correlates of voice perception in children with and without ASD. METHODS: Sixteen children with autism and 16 age-matched typically developing children heard vocal (speech and non-speech) and non-vocal sounds while their electroencephalographic activity was recorded; overall IQ was smaller in the group of children with ASD. ERP amplitudes were compared using non-parametric statistical tests at each electrode and in successive 20-ms time windows. Within each group, differences between conditions were assessed using a non-parametric Quade test between 0 and 400 ms post-stimulus. Inter-group comparisons of ERP amplitudes were performed using non-paired Kruskal-Wallis tests between 140 and 180 ms post-stimulus. RESULTS: Typically developing children showed the classical voice-sensitive response over right fronto-temporal electrodes, for both speech and non-speech vocal sounds. Children with ASD did not show a preferential response to vocal sounds. Inter-group analysis showed no difference in the processing of vocal sounds, both speech and non-speech, but significant differences in the processing of non-vocal sounds over right fronto-temporal sites. CONCLUSIONS: Our results demonstrate a lack of voice-preferential response in children with autism spectrum disorders. In contrast to observations in adults with ASD, the lack of voice-preferential response was attributed to an atypical response to non-vocal sounds, which was overall more similar to the event-related potentials evoked by vocal sounds in both groups. This result suggests atypical maturation processes in ASD impeding the specialization of temporal regions in voice processing.

THILLAY, Auteur ; Emmanuelle HOUY-DURAND, Auteur ; S. ROUX, Auteur ; Aurélie BIDET-CAULET, Auteur ; Frédérique BONNET-BRILHAULT, Auteur ; Magali BATTY, Auteur Article en page(s) : p.3377-3386 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Visual evoked potentials Pattern-reversal paradigm Sensory symptoms Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is characterized by atypical visual perception both in the social and nonsocial domain. In order to measure a reliable visual response, visual evoked potentials were recorded during a passive pattern-reversal stimulation in adolescents and adults with and without ASD. While the present results show the same age-related changes in both autistic and non-autistic groups, they reveal a smaller P100 amplitude in the ASD group compared to controls. These results confirm that early visual responses are affected in ASD even with a simple, non social and passive stimulation and suggest that they should be considered in order to better understand higher-level processes.
