Inflectional morphology in high-functioning autism: Evidence for speeded grammatical processing / Matthew WALENSKI in Research in Autism Spectrum Disorders, 8-11 (November 2014)
[article]
Titre : Inflectional morphology in high-functioning autism: Evidence for speeded grammatical processing Type de document : Texte imprimé et/ou numérique Auteurs : Matthew WALENSKI, Auteur ; Stewart H. MOSTOFSKY, Auteur ; Michael T. ULLMAN, Auteur Article en page(s) : p.1607-1621 Langues : Anglais (eng) Mots-clés : Autism Language Morphology Past tense Procedural memory Basal-ganglia Index. décimale : PER Périodiques Résumé : Autism is characterized by language and communication deficits. We investigated grammatical and lexical processes in high-functioning autism by contrasting the production of regular and irregular past-tense forms. Boys with autism and typically developing control boys did not differ in accuracy or error rates. However, boys with autism were significantly faster than controls at producing rule-governed past-tenses (slip-slipped, plim-plimmed, bring-bringed), though not lexically dependent past-tenses (bring-brought, squeeze-squeezed, splim-splam). This pattern mirrors previous findings from Tourette syndrome attributed to abnormalities of frontal/basal-ganglia circuits that underlie grammar. We suggest a similar abnormality underlying language in autism. Importantly, even when children with autism show apparently normal language (e.g., in accuracy or with diagnostic instruments), processes and/or brain structures subserving language may be atypical in the disorder.

Titre : Syntax and Morphology in Danish-Speaking Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Cecilia BRYNSKOV, Auteur ; Inge-Marie EIGSTI, Auteur ; Meta JØRGENSEN, Auteur ; Sanne LEMCKE, Auteur ; Ocke-Schwen BOHN, Auteur ; Peter KRØJGAARD, Auteur Article en page(s) : p.373-383 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Vocabulary Syntax Morphology Sentence repetition Early language delay Index. décimale : PER Périodiques Résumé : The current study examined delays in syntax and morphology, and vocabulary, in autism spectrum disorder (ASD). Children ages 4–6 years with ASD (n?=?21) and typical development (n?=?21), matched on nonverbal mental age, completed five language tasks. The ASD group had significant delays in both syntax and morphology, and vocabulary measures, with significant within-group heterogeneity; furthermore, syntactic and morphological measures were impaired even for subgroups matched on vocabulary. Children in the ASD group without early language delay showed syntactic and morphological impairment, with intact performance on vocabulary and sentence repetition. Findings indicate that syntactic and morphological impairments are a significant concern for high-functioning children with ASD, and may be overlooked if language evaluation focuses exclusively on vocabulary.

Many cognitive, behavioural and biological features associated with ASC also occur on a continuum in the general population. The aim of the present study was to examine subthreshold levels of autistic traits and facial morphology in non-autistic individuals. Facial asymmetry was measured using three-dimensional facial photogrammetry, and the Autism-spectrum Quotient was used to measure autistic-like traits in a community-ascertained sample of young adults (n?=?289). After accounting for covariates, there were no significant associations observed between autistic-like traits and facial asymmetry, suggesting that any potential facial morphology differences linked to ASC may be limited to the clinical condition.

Thirteen monolingual and thirteen bilingual children with ASD without intellectual disability, were compared on standardized measures of vocabulary and morphology. Findings revealed that bilingual children performed in the average monolingual range on a standardized receptive vocabulary test and slightly below the average range on a standardized morphological task in their dominant language. Prior work indicates that bilingual exposure is not detrimental for early language development in children with autism. The current findings suggest that at school age, bilinguals with ASD show similar language development patterns as those described in the literature on typically-developing bilinguals.

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.

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.
