Vocabulary comprehension in adults with fragile X syndrome (FXS) / A. HOFFMANN in Journal of Neurodevelopmental Disorders, 11-1 (December 2019)
[article]
Titre : Vocabulary comprehension in adults with fragile X syndrome (FXS) Type de document : Texte imprimé et/ou numérique Auteurs : A. HOFFMANN, Auteur ; S. E. KRAUSE, Auteur ; J. WUU, Auteur ; S. LEURGANS, Auteur ; S. J. GUTER, Auteur ; S. S. BLOCK, Auteur ; J. SALT, Auteur ; E. COOK, Auteur ; D. M. MAINO, Auteur ; Elizabeth BERRY-KRAVIS, Auteur Article en page(s) : 25 p. Langues : Anglais (eng) Mots-clés : Adults Cognition Comprehension Fragile X syndrome Language Vocabulary Index. décimale : PER Périodiques Résumé : BACKGROUND: Receptive and expressive vocabulary in adult and adolescent males with fragile X syndrome (FXS) have been shown as significantly lower than their chronological age; however, receptive vocabulary has been considered a strength relative to mental age. This has not been formally examined, however, and data are needed to compare receptive vocabulary with other language skills and with mental age in individuals with FXS. This is especially important as vocabulary measures are sometimes used as a proxy to estimate language ability. METHODS: This preliminary study examined receptive vocabulary, global language, and cognitive skills in 42 adults (33 males and 9 females) with FXS as a portion of the baseline evaluation prior to randomization in a clinical trial of ampakine CX516. The battery of standardized tests addressed receptive vocabulary with the Peabody Picture Vocabulary Test, Third Edition (PPVT-III), receptive and expressive language (termed henceforth as global language) via the Preschool Language Scale, Fourth Edition or the Clinical Evaluation of Language Fundamentals, Third Edition, and non-verbal cognition via the Stanford-Binet Intelligence Scales, Fourth Edition (SB-IV). RESULTS: Results showed (1) significantly higher receptive vocabulary than global language, (2) significantly better receptive vocabulary than non-verbal cognition, (3) equivalent non-verbal cognition and global language, and (4) severity of autism symptomatology was not correlated to receptive vocabulary or global language once non-verbal cognition was removed as factor. The scores from the PPVT-III did not represent the global language skills in our sample of adults with FXS. CONCLUSIONS: Findings from this investigation strongly suggest that the PPVT-III should not be used as a screening tool for language levels or cognitive function in clinical studies since the scores from the PPVT-III were not representative of global language or non-verbal cognitive skills in adults with intellectual disabilities. This finding is critical in order to understand how to evaluate, as well as to treat, language in individuals with FXS. Development of efficient and appropriate tools to measure language, cognition, and behavior in individuals with FXS is essential.

We also examined infant responses to parent gestures and assessed the extent to which parent gesture relates to vocabulary development. Parents of three groups gestured in similar frequencies and proportions. Infants, in turn, responded similarly to parent gestures regardless of the infant's ASD risk and later diagnosis. Finally, parents who gestured more at 12 months had children with better vocabulary at 36 months than parents who gestured less. These findings highlight the importance of examining parent gestures when predicting language development.

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.

NADIG, Auteur Article en page(s) : p.1667-1678 Langues : Anglais (eng) Mots-clés : amount of language exposure autism spectrum disorder bilingualism morphology school-age children vocabulary Index. décimale : PER Périodiques Résumé : Studies of bilingual children with Autism Spectrum Disorders (ASD) have focused on early language development using parent report measures. However, the effect of bilingual exposure on more complex linguistic abilities is unknown. In the current study, we examined the impact of amount of language exposure on vocabulary and morphological skills in school-aged children with ASD who did not have intellectual disability. Forty-seven typically developing children and 30 children with ASD with varying exposure to French participated in the study. We investigated the impact of amount of language exposure, nonverbal IQ, age, and working memory on language abilities via regression analyses. Current amount of language exposure was the strongest predictor of both vocabulary skills (accounting for 62% of the variance) and morphological skills (accounting for 49% of the variance), for both typically-developing children and children with ASD. These findings highlight the central role amount of language exposure plays in vocabulary and morphological development for children with ASD, as it does for typically-developing children. In addition, they provide further evidence that, when provided with adequate language exposure, many children with ASD are capable of acquiring two languages. Autism Research 2018, 11: 1667-1678. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We studied typically developing children and children with ASD living in a bilingual society who had varying exposure to French (ranging from bilinguals to monolinguals). We investigated the impact of amount of language exposure, nonverbal IQ, age, and working memory on their vocabulary and morphological skills. Current amount of language exposure was the strongest predictor of language skills in both groups of children. Findings indicate that when provided with adequate language exposure, many children with ASD are capable of acquiring two languages.

We found that parents in the three groups produced similar numbers of declarative and imperative gestures during a 10-minute parent-child interaction in the lab at 12 months and that 12-month parental declarative gesture use was significantly, positively associated with children's 36-month vocabulary scores. Encouraging parental use of declarative gestures with infants could have important implications for language development.
