RUSSO, Auteur ; Steven ZECKER, Auteur ; Barbara TROMMER, Auteur ; Julia CHEN, Auteur ; Nina KRAUS, Auteur Année de publication : 2009 Article en page(s) : p.1185-1196 Langues : Anglais (eng) Mots-clés : Autism Cortical-encoding Speech Background-noise Children Evoked-potentials Index. décimale : PER Périodiques Résumé : This study provides new evidence of deficient auditory cortical processing of speech in noise in autism spectrum disorders (ASD). Speech-evoked responses (~100–300 ms) in quiet and background noise were evaluated in typically-developing (TD) children and children with ASD. ASD responses showed delayed timing (both conditions) and reduced amplitudes (quiet) compared to TD responses. As expected, TD responses in noise were delayed and reduced compared to quiet responses. However, minimal quiet-to-noise response differences were found in children with ASD, presumably because quiet responses were already severely degraded. Moreover, ASD quiet responses resembled TD noise responses, implying that children with ASD process speech in quiet only as well as TD children do in background noise.

Neural Processing of Speech Sounds in ASD and First-Degree Relatives / Shivani P. PATEL in Journal of Autism and Developmental Disorders, 53-8 (August 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-8 (August 2023) . - p.3257-3271 Titre : Neural Processing of Speech Sounds in ASD and First-Degree Relatives Type de document : Texte imprimé et/ou numérique Auteurs : Shivani P. PATEL, Auteur ; Molly WINSTON, Auteur ; Janna GUILFOYLE, Auteur ; Trent NICOL, Auteur ; Gary E. MARTIN, Auteur ; Kritika NAYAR, Auteur ; Nina KRAUS, Auteur ; Molly LOSH, Auteur Article en page(s) : p.3257-3271 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Efficient neural encoding of sound plays a critical role in speech and language, and when impaired, may have reverberating effects on communication skills. This study investigated disruptions to neural processing of temporal and spectral properties of speech in individuals with ASD and their parents and found evidence of inefficient temporal encoding of speech sounds in both groups. The ASD group further demonstrated less robust neural representation of spectral properties of speech sounds. Associations between neural processing of speech sounds and language-related abilities were evident in both groups. Parent-child associations were also detected in neural pitch processing. Together, results suggest that atypical neural processing of speech sounds is a heritable ingredient contributing to the ASD language phenotype.
