Brief Report: Visuospatial and Spoken Language Recall in Autism: Preliminary Findings / Kelly L. COBURN in Journal of Autism and Developmental Disorders, 52-6 (June 2022)
[article]
Titre : Brief Report: Visuospatial and Spoken Language Recall in Autism: Preliminary Findings Type de document : Texte imprimé et/ou numérique Auteurs : Kelly L. COBURN, Auteur ; Diane L. WILLIAMS, Auteur Article en page(s) : p.2831-2837 Langues : Anglais (eng) Mots-clés : Autism Communication Multimodal Recall Spoken language Visuospatial Index. décimale : PER Périodiques Résumé : Challenges to verbal encoding may affect the ability of autistic individuals to express their ideas. Therefore, visuospatial expression may represent a person's knowledge and skills more accurately than spoken language. To test this hypothesis, we asked seven autistic adults to linguistically retell and visuospatially reenact several animated clips. On average, visuospatial responses contained more correct elements than spoken responses. The level of intention of the three stimulus categories did not systematically affect response accuracy. Participants who produced visuospatial responses before spoken responses and those who had watched a greater number of stimuli assigned higher intentionality to shapes in the animations that were designed to elicit mentalizing. The modality used for expression may affect accuracy of responses by autistic individuals.

WATSON, Auteur ; Warren LAMBERT, Auteur Article en page(s) : p.1254-1270 Langues : Anglais (eng) Mots-clés : Autism Spoken language Useful speech Predictors Nonverbal Longitudinal Index. décimale : PER Périodiques Résumé : Eighty-seven preschoolers with autism spectrum disorders who were initially nonverbal (under 6 words in language sample and under 21 parent-reported words said) were assessed at five time points over 16 months. Statistical models that accounted for the intercorrelation among nine theoretically- and empirically-motivated predictors, as well as two background variables (i.e., cognitive impairment level, autism severity), were applied to identify value-added predictors of expressive and receptive spoken language growth and outcome. The results indicate that responding to joint attention, intentional communication, and parent linguistic responses were value-added predictors of both expressive and receptive spoken language growth. In addition, consonant inventory was a value-added predictor of expressive growth; early receptive vocabulary and autism severity were value-added predictors of receptive growth.

Titre : Behavioral predictors of improved speech output in minimally verbal children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Karen CHENAUSKY, Auteur ; A. NORTON, Auteur ; Helen TAGER-FLUSBERG, Auteur ; G. SCHLAUG, Auteur Article en page(s) : p.1356-1365 Langues : Anglais (eng) Mots-clés : autism spectrum disorder intonation longitudinal data analysis minimally verbal spoken language Index. décimale : PER Périodiques Résumé : We investigated the relationship between eight theoretically motivated behavioral variables and a spoken-language-related outcome measure, after 25 sessions of treatment for speech production in 38 minimally verbal children with autism. After removing potential predictors that were uncorrelated with the outcome variable, two remained. We used both complete-case and multiple-imputation analyses to address missing predictor data and performed linear regressions to identify significant predictors of change in percent syllables approximately correct after treatment. Baseline phonetic inventory (the number of English phonemes repeated correctly) was the most robust predictor of improvement. In the group of 17 participants with complete data, ADOS score also significantly predicted the outcome. In contrast to some earlier studies, nonverbal IQ, baseline levels of expressive language, and younger age did not significantly predict improvement. The present results are not only consistent with previous studies showing that verbal imitation and autism severity significantly predict spoken language outcomes in preschool-aged minimally verbal children with autism, but also extend these findings to older minimally verbal children with autism. Autism Res 2018, 11: 1356-1365. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We wished to understand what baseline factors predicted whether minimally verbal children with autism would improve after treatment for spoken language. The outcome measure was change in percentage (%) syllables approximately correct on a set of 30 two-syllable words or phrases. Fifteen were both practiced in treatment and tested; the remainder were not practiced in treatment, but only tested, to assess how well children were able to generalize their new skills to an untrained set of words. Potential predictors tested were sex, age, expressive language, phonetic inventory (the number of English speech sounds repeated correctly), autism severity, and nonverbal IQ. Phonetic inventory and (for some children) autism severity predicted children's posttreatment improvement. Nonverbal IQ and expressive language ability did not predict improvement, nor did younger age, suggesting that some older children with autism may be candidates for speech therapy.

Titre : Minimally Verbal School-Aged Children with Autism Spectrum Disorder: The Neglected End of the Spectrum Type de document : Texte imprimé et/ou numérique Auteurs : Helen TAGER-FLUSBERG, Auteur ; Connie KASARI, Auteur Année de publication : 2013 Article en page(s) : p.468-478 Langues : Anglais (eng) Mots-clés : behavioral intervention intervention early intervention intervention school age pediatrics spoken language minimally verbal ASD alternative and augmentative communication eye-tracking Index. décimale : PER Périodiques Résumé : It is currently estimated that about 30% of children with autism spectrum disorder remain minimally verbal, even after receiving years of interventions and a range of educational opportunities. Very little is known about the individuals at this end of the autism spectrum, in part because this is a highly variable population with no single set of defining characteristics or patterns of skills or deficits, and in part because it is extremely challenging to provide reliable or valid assessments of their developmental functioning. In this paper, we summarize current knowledge based on research including minimally verbal children. We review promising new novel methods for assessing the verbal and nonverbal abilities of minimally verbal school-aged children, including eye-tracking and brain-imaging methods that do not require overt responses. We then review what is known about interventions that may be effective in improving language and communication skills, including discussion of both nonaugmentative and augmentative methods. In the final section of the paper, we discuss the gaps in the literature and needs for future research.

WATSON, Auteur Article en page(s) : p.301-310 Langues : Anglais (eng) Mots-clés : autism spoken language vocabulary useful speech minimally verbal longitudinal Index. décimale : PER Périodiques Résumé : We tested the relative levels (i.e., age equivalencies) of concurrent cross-modality (receptive and expressive) vocabulary and the relative strength of the longitudinal, cross-modality associations between early and later vocabulary sizes in minimally verbal preschoolers with ASD. Eighty-seven children participated. Parent-reported vocabulary was assessed at four periods separated by 4 months each. Expressive age equivalent scores were higher than receptive age equivalent scores at all four periods. Cross-lagged panel analysis was used to rule out common, but trivial, explanations for differences between the longitudinal associations of interest. Key associations were tested across intervals that varied from 8 to 12 months. In two of the three tested panels, the associations between early expressive vocabulary size and later receptive vocabulary size were stronger than the associations between early receptive vocabulary size and later expressive vocabulary size, providing evidence that is consistent with the hypothesis that expressive vocabulary size drives receptive vocabulary size in minimally verbal preschoolers with ASD.
