Brief Report: Learning Language Through Overhearing in Children with ASD / Rhiannon J. LUYSTER in Journal of Autism and Developmental Disorders, 50-7 (July 2020)
[article]
Titre : Brief Report: Learning Language Through Overhearing in Children with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Rhiannon J. LUYSTER, Auteur ; Sudha ARUNACHALAM, Auteur Article en page(s) : p.2616-2624 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Language Word learning Index. décimale : PER Périodiques Résumé : We explored whether children with autism spectrum disorder (ASD) learn new nouns from overheard speech. Thirteen children (4-5 years) with ASD participated in an Addressed condition, in which they were directly taught a novel label (e.g., toma) for one of three novel objects, and an Overheard condition, in which the objects and label were presented in a conversation between two adults. In both conditions, children were then asked to identify the labeled object (e.g., "find the toma"). Children selected the target novel object at rates above chance in the Addressed condition, and of critical importance, they also did so in the Overheard condition. This suggests that, like TD children, children with ASD may learn from language that is not directed to them.

Titre : Eye-Tracking Measurements of Language Processing: Developmental Differences in Children at High Risk for ASD Type de document : Texte imprimé et/ou numérique Auteurs : Meia CHITA-TEGMARK, Auteur ; Sudha ARUNACHALAM, Auteur ; Charles A. NELSON, Auteur ; Helen TAGER-FLUSBERG, Auteur Article en page(s) : p.3327-3338 Langues : Anglais (eng) Mots-clés : Autism Development Word comprehension Processing speed Eye tracking Index. décimale : PER Périodiques Résumé : To explore how being at high risk for autism spectrum disorder (ASD), based on having an older sibling diagnosed with ASD, affects word comprehension and language processing speed, 18-, 24- and 36-month-old children, at high and low risk for ASD were tested in a cross- sectional study, on an eye gaze measure of receptive language that measured how accurately and rapidly the children looked at named target images. There were no significant differences between the high risk ASD group and the low risk control group of 18- and 24-month-olds. However, 36-month-olds in the high risk for ASD group performed significantly worse on the accuracy measure, but not on the speed measure. We propose that the language processing efficiency of the high risk group is not compromised, but other vocabulary acquisition factors might have lead to the high risk 36-month-olds to comprehend significantly fewer nouns on our measure.

Titre : The integrity of lexical acquisition mechanisms in autism spectrum disorders: A research review Type de document : Texte imprimé et/ou numérique Auteurs : Sudha ARUNACHALAM, Auteur ; Rhiannon J. LUYSTER, Auteur Article en page(s) : p.810-828 Langues : Anglais (eng) Mots-clés : Language Developmental Psychology Pediatrics Children Infants Learning Index. décimale : PER Périodiques Résumé : Research on autism spectrum disorders (ASD) has rapidly expanded in recent years, yielding important developments in both theory and practice. While we have gained important insights into how children with ASD differ from typically developing (TD) children in terms of phenotypic features, less has been learned about if and how development in ASD differs from typical development in terms of underlying mechanisms of change. This article aims to provide a review of processes subserving lexical development in ASD, with the goal of identifying contributing factors to the heterogeneity of language outcomes in ASD. The focus is on available evidence of the integrity or disruption of these mechanisms in ASD, as well as their significance for vocabulary development; topics include early speech perception and preference, speech segmentation, word learning, and category formation. Significant gaps in the literature are identified and future directions are suggested.
