Autonomic and Electrophysiological Evidence for Reduced Auditory Habituation in Autism / T. K. GANDHI in Journal of Autism and Developmental Disorders, 51-7 (July 2021)

Titre : Autonomic and Electrophysiological Evidence for Reduced Auditory Habituation in Autism Type de document : Texte imprimé et/ou numérique Auteurs : T. K. GANDHI, Auteur ; K. TSOURIDES, Auteur ; N. SINGHAL, Auteur ; A. CARDINAUX, Auteur ; W. JAMAL, Auteur ; D. PANTAZIS, Auteur ; M. KJELGAARD, Auteur ; P.

What aspects of sensory processing are affected in autism? Although sensory processing can be studied along multiple dimensions, two of the most basic ones involve examining instantaneous sensory responses and how the responses change over time. These correspond to the dimensions of 'sensitivity' and 'habituation'. Results thus far have indicated that autistic individuals do not differ systematically from controls in sensory acuity/sensitivity. However, data from studies of habituation have been equivocal. We have studied habituation in autism using two measures: galvanic skin response (GSR) and magneto-encephalography (MEG). We report data from two independent studies. The first study, was conducted with 13 autistic and 13 age-matched neurotypical young adults and used GSR to assess response to an extended metronomic sequence. The second study involved 24 participants (12 with an ASD diagnosis), different from those in study 1, spanning the pre-adolescent to young adult age range, and used MEG. Both studies reveal consistent patterns of reduced habituation in autistic participants. These results suggest that autism, through mechanisms that are yet to be elucidated, compromises a fundamental aspect of sensory processing, at least in the auditory domain. We discuss the implications for understanding sensory hypersensitivities, a hallmark phenotypic feature of autism, recently proposed theoretical accounts, and potential relevance for early detection of risk for autism.

HASKINS, Auteur ; M. KJELGAARD, Auteur ; P. SINHA, Auteur Article en page(s) : p.3153-3164 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Autistic Disorder Child Cognition Electroencephalography Habituation, Psychophysiologic Humans Audition Autism Hyper and hypo-sensitivity Sensory habituation Vision Index. décimale : PER Périodiques Résumé : Autism is strongly associated with sensory processing difficulties. We investigate sensory habituation, given its relevance for understanding important phenotypic traits like hyper- and hypo-sensitivities. We collected electroencephalography data from 22 neuro-typical(NT) and 13 autistic(ASD) children during the presentation of visual and auditory sequences of repeated stimuli. Our data show that the ASD children have significantly reduced habituation relative to the NT children for both auditory and visual stimuli. These results point to impaired habituation as a modality-general phenomenon in ASD. Additionally, the rates of habituation are correlated with several clinical scores associated with competence along diverse phenotypic dimensions. These data suggest that the sensory difficulties in autism are likely to be associated with reduced habituation and are related to clinical symptomology.
