Neural Correlates of Sensory Hyporesponsiveness in Toddlers at High Risk for Autism Spectrum Disorder / David M. SIMON in Journal of Autism and Developmental Disorders, 47-9 (September 2017) 

Public ISBD [article]  in Journal of Autism and Developmental Disorders > 47-9 (September 2017) . - p.2710-2722 Titre : Neural Correlates of Sensory Hyporesponsiveness in Toddlers at High Risk for Autism Spectrum Disorder Type de document : texte imprimé Auteurs : David M.

Younger siblings of individuals with ASD are at a greatly elevated risk of a future diagnosis of ASD, but little is known about the neural basis of sensory responsiveness patterns in this population. Younger siblings (n?=?20) of children diagnosed with ASD participated in resting electroencephalography (EEG) at an age of 18 months. Data on toddlers’ sensory responsiveness were obtained using the Sensory Experiences Questionnaire. Correlations were present between hyporesponsiveness and patterns of oscillatory power, functional connectivity, and signal complexity. Our findings suggest that neural signal features hold promise for facilitating early identification and targeted remediation in young children at risk for ASD.

Plasticity of temporal binding in children with autism spectrum disorder: A single case experimental design perceptual training study / Jacob I. FELDMAN in Research in Autism Spectrum Disorders, 74 (June 2020) 

Public ISBD [article]  in Research in Autism Spectrum Disorders > 74 (June 2020) . - p.101555 Titre : Plasticity of temporal binding in children with autism spectrum disorder: A single case experimental design perceptual training study Type de document : texte imprimé Auteurs : Jacob I.

WALLACE, Auteur ; Tiffany G. WOYNAROSKI, Auteur Article en page(s) : p.101555 Langues : Anglais (eng) Mots-clés : Autism  Multisensory integration  Perceptual training  Audiovisual  Plasticity Index. décimale : PER Périodiques Résumé : Background Many children with autism spectrum disorder (ASD) demonstrate atypical responses to multisensory stimuli. These disruptions, which are frequently seen in response to audiovisual speech, may produce cascading effects on the broader development of children with ASD. Perceptual training has been shown to enhance multisensory speech perception in typically developed adults. This study was the first to examine the effects of perceptual training on audiovisual speech perception in children with ASD. Method A multiple baseline across participants design was utilized with four 7- to 13-year-old children with ASD. The dependent variable, which was probed outside the training task each day using a simultaneity judgment task in baseline, intervention, and maintenance conditions, was audiovisual temporal binding window (TBW), an index of multisensory temporal acuity. During perceptual training, participants completed the same simultaneity judgment task with feedback on their accuracy after each trial in easy-, medium-, and hard-difficulty blocks. Results A functional relation between the multisensory perceptual training program and TBW size was not observed. Of the three participants who were entered into training, one participant demonstrated a strong effect, characterized by a fairly immediate change in TBW trend. The two remaining participants demonstrated a less clear response (i.e., longer latency to effect, lack of functional independence). The first participant to enter the training condition demonstrated some maintenance of a narrower TBW post-training. Conclusions Results indicate TBWs in children with ASD may be malleable, but additional research is needed and may entail further adaptation to the multisensory perceptual training paradigm.
