Cerebellum, Language, and Cognition in Autism and Specific Language Impairment / Steven M. HODGE in Journal of Autism and Developmental Disorders, 40-3 (March 2010)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 40-3 (March 2010) . - p.300-316 Titre : Cerebellum, Language, and Cognition in Autism and Specific Language Impairment Type de document : Texte imprimé et/ou numérique Auteurs : Steven M.

MCGRATH, Auteur ; Shelly D. STEELE, Auteur ; Gordon J. HARRIS, Auteur Année de publication : 2010 Article en page(s) : p.300-316 Langues : Anglais (eng) Mots-clés : Autism Specific-language-impairment Cerebellum Broca’s-area Asymmetry Index. décimale : PER Périodiques Résumé : We performed cerebellum segmentation and parcellation on magnetic resonance images from right-handed boys, aged 6–13 years, including 22 boys with autism [16 with language impairment (ALI)], 9 boys with Specific Language Impairment (SLI), and 11 normal controls. Language-impaired groups had reversed asymmetry relative to unimpaired groups in posterior-lateral cerebellar lobule VIIIA (right side larger in unimpaired groups, left side larger in ALI and SLI), contralateral to previous findings in inferior frontal cortex language areas. Lobule VIIA Crus I was smaller in SLI than in ALI. Vermis volume, particularly anterior I–V, was decreased in language-impaired groups. Language performance test scores correlated with lobule VIIIA asymmetry and with anterior vermis volume. These findings suggest ALI and SLI subjects show abnormalities in neurodevelopment of fronto-corticocerebellar circuits that manage motor control and the processing of language, cognition, working memory, and attention.

Spatial Working Memory Deficits in Autism / Shelly D. STEELE in Journal of Autism and Developmental Disorders, 37-4 (April 2007)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 37-4 (April 2007) . - p.605-612 Titre : Spatial Working Memory Deficits in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Shelly D. STEELE, Auteur ; Nancy J. MINSHEW, Auteur ; Beatriz LUNA, Auteur ; John A. SWEENEY, Auteur Année de publication : 2007 Article en page(s) : p.605-612 Langues : Anglais (eng) Mots-clés : High-functioning-autism CANTAB Executive-function Frontal-lobes Cognition Neuropsychology Index. décimale : PER Périodiques Résumé : Previous studies have reported working memory deficits in autism, but this finding has been inconsistent. One possibility is that deficits in this domain may be present only when working memory load exceeds some limited capacity. High-functioning individuals with autism performed the CANTAB computerized test of spatial working memory. Individuals with autism made more errors than a matched group of typically developing controls on this task, and were less likely to consistently use a specific organized search strategy to complete the task. Overall, these results demonstrate reduced spatial working memory abilities in autism, and extend previous findings by demonstrating that these deficits are significant when tasks impose heavier demands on working memory.
