MAFFEI, Auteur ; Karen V. CHENAUSKY, Auteur ; Simone V. GILL, Auteur ; Helen TAGER-FLUSBERG, Auteur ; Jordan R. GREEN, Auteur Article en page(s) : p.879-917 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Oromotor functioning plays a foundational role in spoken communication and feeding, two areas of significant difficulty for many autistic individuals. However, despite years of research and established differences in gross and fine motor skills in this population, there is currently no clear consensus regarding the presence or nature of oral motor control deficits in autistic individuals. In this scoping review, we summarize research published between 1994 and 2022 to answer the following research questions: (1) What methods have been used to investigate oromotor functioning in autistic individuals? (2) Which oromotor behaviors have been investigated in this population? and (3) What conclusions can be drawn regarding oromotor skills in this population? Seven online databases were searched resulting in 107 studies meeting our inclusion criteria. Included studies varied widely in sample characteristics, behaviors analyzed, and research methodology. The large majority (81%) of included studies report a significant oromotor abnormality related to speech production, nonspeech oromotor skills, or feeding within a sample of autistic individuals based on age norms or in comparison to a control group. We examine these findings to identify trends, address methodological aspects hindering cross-study synthesis and generalization, and provide suggestions for future research.

Vowel distinctiveness as a concurrent predictor of expressive language function in autistic children / Paul J. SIMEONE in Autism Research, 17-2 (February 2024)  

Public ISBD [article]  inAutism Research > 17-2 (February 2024) . - p.419-431 Titre : Vowel distinctiveness as a concurrent predictor of expressive language function in autistic children Type de document : Texte imprimé et/ou numérique Auteurs : Paul J. SIMEONE, Auteur ; Jordan R. GREEN, Auteur ; Helen TAGER-FLUSBERG, Auteur ; Karen V. CHENAUSKY, Auteur Article en page(s) : p.419-431 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Speech ability may limit spoken language development in some minimally verbal autistic children. In this study, we aimed to determine whether an acoustic measure of speech production, vowel distinctiveness, is concurrently related to expressive language (EL) for autistic children. Syllables containing the vowels [i] and [a] were recorded remotely from 27 autistic children (4;1-7;11) with a range of spoken language abilities. Vowel distinctiveness was calculated using automatic formant tracking software. Robust hierarchical regressions were conducted with receptive language (RL) and vowel distinctiveness as predictors of EL. Hierarchical regressions were also conducted within a High EL and a Low EL subgroup. Vowel distinctiveness accounted for 29% of the variance in EL for the entire group, RL for 38%. For the Low EL group, only vowel distinctiveness was significant, accounting for 38% of variance in EL. Conversely, in the High EL group, only RL was significant and accounted for 26% of variance in EL. Replicating previous results, speech production and RL significantly predicted concurrent EL in autistic children, with speech production being the sole significant predictor for the Low EL group and RL the sole significant predictor for the High EL group. Further work is needed to determine whether vowel distinctiveness longitudinally, as well as concurrently, predicts EL. Findings have important implications for the early identification of language impairment and in developing language interventions for autistic children.
