Autonomic and Electrophysiological Evidence for Reduced Auditory Habituation in Autism / T. K. GANDHI in Journal of Autism and Developmental Disorders, 51-7 (July 2021)
[article]
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. SINHA, Auteur Article en page(s) : p.2218-2228 Langues : Anglais (eng) Mots-clés : Adolescent Autistic Disorder/physiopathology Case-Control Studies Child Female Galvanic Skin Response Habituation, Psychophysiologic/physiology Humans Magnetoencephalography Male Perception/physiology Young Adult Autism Gsr Habituation Hypersensitivities Meg Index. décimale : PER Périodiques Résumé : It is estimated that nearly 90% of children on the autism spectrum exhibit sensory atypicalities. 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.

Titre : Associations Between Language Development and Skin Conductance Responses to Faces and Eye Gaze in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Steven D. STAGG, Auteur ; Robert DAVIS, Auteur ; Pamela HEATON, Auteur Article en page(s) : p.2303-2311 Langues : Anglais (eng) Mots-clés : Language delay Galvanic skin response Language onset Autism spectrum disorder Faces Eye-gaze Index. décimale : PER Périodiques Résumé : Attention to social stimuli is associated with language development, and arousal is associated with the increased viewing of stimuli. We investigated whether skin conductance responses (SCRs) are associated with language development in autism spectrum disorder (ASD): a population that shows abnormalities in both attention to others and language development. A sample of 32 children with ASD (7–15 year; M = 9 year) was divided into two groups, based on language onset histories. A typically developing comparison group consisted of 18 age and IQ matched children. SCRs were taken as the participants viewed faces. SCRs differentiated the ASD group based on language onset and were associated with abnormal attention to gaze in infancy and subsequent language development.

Titre : The relationship between autism symptoms and arousal level in toddlers with autism spectrum disorder, as measured by electrodermal activity Type de document : Texte imprimé et/ou numérique Auteurs : Emily Barbara PRINCE, Auteur ; Elizabeth S KIM, Auteur ; Carla A. WALL, Auteur ; Eugenia GISIN, Auteur ; Matthew S GOODWIN, Auteur ; Elizabeth SCHOEN SIMMONS, Auteur ; Kasia CHAWARSKA, Auteur ; Frederick SHIC, Auteur Article en page(s) : p.504-508 Langues : Anglais (eng) Mots-clés : ASD electrodermal activity galvanic skin response language naturalistic environment play skin conductance toddlers Index. décimale : PER Périodiques Résumé : Electrodermal activity was examined as a measure of physiological arousal within a naturalistic play context in 2-year-old toddlers (N?=?27) with and without autism spectrum disorder. Toddlers with autism spectrum disorder were found to have greater increases in skin conductance level than their typical peers in response to administered play activities. In the autism spectrum disorder group, a positive relationship was observed between restrictive and repetitive behaviors and skin conductance level increases in response to mechanical toys, whereas the opposite pattern was observed for passive toys. This preliminary study is the first to examine electrodermal activity levels in toddlers with autism spectrum disorder during play-based, naturalistic settings, and it highlights the potential for electrodermal activity as a measure of individual variability within autism spectrum disorder and early development.
