Impaired P1 Habituation and Mismatch Negativity in Children with Autism Spectrum Disorder / Francisco J. RUIZ-MARTINEZ in Journal of Autism and Developmental Disorders, 50-2 (February 2020)
[article]
Titre : Impaired P1 Habituation and Mismatch Negativity in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Francisco J. RUIZ-MARTINEZ, Auteur ; Elena I. RODRIGUEZ-MARTINEZ, Auteur ; C. Ellie WILSON, Auteur ; Shu YAU, Auteur ; David SALDANA, Auteur ; Carlos M. GOMEZ, Auteur Article en page(s) : p.603-616 Langues : Anglais (eng) Mots-clés : Auditory P1 Autism Habituation Mismatch negativity Sensory perception Index. décimale : PER Périodiques Résumé : Passive testing of auditory function is an important objective in individuals with ASD due to known difficulties in understanding and/or following task instructions. In present study the habituation to standard tones following deviants and the auditory discriminative processes were examined in two conditions: electronic and human sounds, in a sample of 16 ASD children. ASD children presented a reduced habituation in the P1 component and a decrease in the amplitude of the mismatch negativity indicating a lower auditory discrimination with respect to controls. MMN amplitude was related to sensory sensitivity. Results suggest an increased activation to repeatedly auditory stimulus and a poor auditory discrimination, for both: electronic and human sounds with consequences on the impaired sensory behavior of ASD subjects.

Titre : Exploring Sensory Subgroups in Typical Development and Autism Spectrum Development Using Factor Mixture Modelling Type de document : Texte imprimé et/ou numérique Auteurs : Patrick DWYER, Auteur ; Emilio FERRER, Auteur ; Clifford D. SARON, Auteur ; Susan M. RIVERA, Auteur Article en page(s) : p.3840-3860 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Autistic Disorder Child Child Development Disorders, Pervasive Humans Auditory P1 Auditory event-related potentials (ERPs) Autism Factor mixture modelling Heterogeneity Sensory processing Index. décimale : PER Périodiques Résumé : This study uses factor mixture modelling of the Short Sensory Profile (SSP) at two time points to describe subgroups of young autistic and typically-developing children. This approach allows separate SSP subscales to influence overall SSP performance differentially across subgroups. Three subgroups were described, one including almost all typically-developing participants plus many autistic participants. SSP performance of a second, largely-autistic subgroup was predominantly shaped by a subscale indexing behaviours of low energy/weakness. Finally, the third subgroup, again largely autistic, contained participants with low (or more "atypical") SSP scores across most subscales. In this subgroup, autistic participants exhibited large P1 amplitudes to loud sounds. Autistic participants in subgroups with more atypical SSP scores had higher anxiety and more sleep disturbances.
