Auditory-visual misalignment: A theoretical perspective on vocabulary delays in children with ASD / Courtney E. VENKER in Autism Research, 11-12 (December 2018)  

Public ISBD [article]  inAutism Research > 11-12 (December 2018) . - p.1621-1628 Titre : Auditory-visual misalignment: A theoretical perspective on vocabulary delays in children with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Courtney E. VENKER, Auteur ; Allison F. BEAN, Auteur ; S. T. KOVER, Auteur Article en page(s) : p.1621-1628 Langues : Anglais (eng) Mots-clés : attention  auditory  developmental psychology  language  learning  visual Index. décimale : PER Périodiques Résumé : In this commentary, we describe a novel theoretical perspective on vocabulary delays in children with autism spectrum disorder (ASD)-a perspective we refer to as auditory-visual misalignment. We synthesize empirical evidence that: (a) as a result of differences in both social and nonsocial visual attention, the auditory-visual statistics available to children with ASD for early word learning are misaligned; (b) this auditory-visual misalignment disrupts word learning and contributes to the vocabulary delays shown by children with ASD; and (c) adopting a perspective of auditory-visual misalignment has important theoretical and clinical implications for understanding and supporting vocabulary development in children with ASD. Theoretically, the auditory-visual misalignment perspective advances our understanding of how attentional differences impact vocabulary development in children with ASD in several ways. By adopting the point of view of the child, we provide a framework that brings together research on social and domain-general visual attention differences in children with ASD. In addition, the auditory-visual misalignment perspective moves current thinking beyond how misalignment disrupts vocabulary development in the moment, and considers the likely consequences of misalignment over developmental time. Finally, considering auditory-visual misalignment may assist in identifying active ingredients of existing language interventions or in developing new interventions that deliver high quality, aligned input. Future research is needed to determine how manipulating auditory-visual alignment changes word learning in ASD and whether the effects of auditory-visual misalignment are unique to ASD or shared with other neurodevelopmental disorders or sources of language impairment. Autism Research 2018, 11: 1621-1628. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This article describes a new way of thinking about vocabulary delays in children with autism spectrum disorder (ASD). We suggest that children with ASD may have difficulty learning words because their attention is not tuned in to what is most important for learning, creating a mismatch between what they see and what they hear. This perspective brings together research on different types of attentional differences in people with ASD. It may also help us to understand how language interventions work.

Contributions of phonological and verbal working memory to language development in adolescents with fragile X syndrome / E. I. PIERPONT in Journal of Neurodevelopmental Disorders, 3-4 (December 2011)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 3-4 (December 2011) . - p.335-47 Titre : Contributions of phonological and verbal working memory to language development in adolescents with fragile X syndrome Type de document : Texte imprimé et/ou numérique Auteurs : E.

Ted BROWN, Auteur Article en page(s) : p.335-47 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability. Although language delays are frequently observed in FXS, neither the longitudinal course of language development nor its cognitive predictors are well understood. The present study investigated whether phonological and working memory skills are predictive of growth in vocabulary and syntax in individuals with FXS during adolescence. Forty-four individuals with FXS (mean age = 12.61 years) completed assessments of phonological memory (nonword repetition and forward digit recall), verbal working memory (backward digit recall), vocabulary, syntax, and nonverbal cognition. Vocabulary and syntax skills were reassessed at a 2-year follow-up. In a series of analyses that controlled for nonverbal cognitive ability and severity of autism symptoms, the relative contributions of phonological and working memory to language change over time were investigated. These relationships were examined separately for boys and girls. In boys with FXS, phonological memory significantly predicted gains in vocabulary and syntax skills. Further, verbal working memory was uniquely associated with vocabulary gains among boys. In girls with FXS, phonological and working memory skills showed no relationship with language change across the 2-year time period. Our findings indicate that, for adolescent boys with FXS, acquisition of vocabulary and syntax may be constrained by the ability to maintain and manipulate phonological representations online. Implications for the identification and treatment of language disorders in this population are discussed. The present study is the first to identify specific cognitive mechanisms contributing to language growth over time in individuals with FXS.

The relation between parent verbal responsiveness and child communication in young children with or at risk for autism spectrum disorder: A systematic review and meta-analysis / S. R. EDMUNDS in Autism Research, 12-5 (May 2019)  

Public ISBD [article]  inAutism Research > 12-5 (May 2019) . - p.715-731 Titre : The relation between parent verbal responsiveness and child communication in young children with or at risk for autism spectrum disorder: A systematic review and meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : S. R. EDMUNDS, Auteur ; S. T. KOVER, Auteur ; W. L. STONE, Auteur Article en page(s) : p.715-731 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  child  communication  language development  parent-child relations  parents Index. décimale : PER Périodiques Résumé : Among preschool-age children with autism spectrum disorder (ASD) and typically developing children, parents' verbal responsiveness (PVR) has long been shown to predict children's later language ability. However, before the age of three, when language develops most rapidly, the early social communication deficits associated with ASD may impact parents' opportunities to facilitate early language development. The aim of this review was to characterize the relation between PVR and the vocal communication ability of children with or at high risk for ASD early in development. Specifically, we examined whether the relation between PVR and child communication varied by type of PVR and by child diagnostic status, as well as whether interventions increased PVR. A systematic multi-database search yielded 25 empirical studies (804 parent-toddler dyads; 30 effect sizes) that met inclusion criteria and related a variable of PVR to a variable of child vocalization or language. Meta-regression analyses revealed that the relation between PVR and child communication was significant regardless of PVR type or child diagnostic status. To date, interventions targeting both PVR and child communication were found to significantly increase PVR, but not child communication, for these populations. Future research should examine parent-child communication in a transactional, longitudinal manner. In addition, these findings have implications for interventions designed to target parents' responsiveness and child communication. Autism Research 2019, 12: 715-731. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: For families with children under 3 years old who are at risk for or diagnosed with ASD, this study revealed empirical evidence of a robust relation between parents'' verbal responsiveness to their children's play and communication and children's communication ability. This relation is similar to that reported in research on typically developing children. Interventions designed to improve parent-child interaction in children with or at risk for ASD may be effective in increasing parents' responsiveness.
