Awareness of Language in Children Who Have Reading Difficulties: Historical Comparisons in a Longitudinal Study / Peter BRYANT in Journal of Child Psychology and Psychiatry, 39-4 (May 1998)
[article]
Titre : Awareness of Language in Children Who Have Reading Difficulties: Historical Comparisons in a Longitudinal Study Type de document : Texte imprimé et/ou numérique Auteurs : Peter BRYANT, Auteur ; Terezinha NUNES, Auteur ; Miriam BINDMAN, Auteur Année de publication : 1998 Article en page(s) : p.501-510 Langues : Anglais (eng) Mots-clés : Language disorder spelling disorder school children language learning reading spelling Index. décimale : PER Périodiques Résumé : We look at the awareness of grammatical distinctions in children with reading difficulties, and at their ability to use this awareness in order to learn about the conventional spellings for morphemes like ”ed“ at the end of past verbs. Using longitudinal methods we show that, initially, children who are to become poor readers are actually better in this aspect of spelling and also in grammatical awareness tasks than younger children of the same reading level: but they are worse than these other children in tasks that tax their knowledge of phonologically based letter-sound correspondences. Later on, however, the poor readers lose their initial advantages in the conventional spelling of morphemes. We conclude that poor readers are initially held back by a failure to learn about letter-sound correspondences, and that this deprives them of successful reading experience, which in turn hampers the growth of their grammatical awareness and their learning how to spell morphemes.

Titre : Predictors of Cognitive Test Patterns in Autism Families Type de document : Texte imprimé et/ou numérique Auteurs : S. E. FOLSTEIN, Auteur ; Susan L. SANTANGELO, Auteur ; S. E. GILMAN, Auteur ; Joseph PIVEN, Auteur ; Rebecca LANDA, Auteur ; Janet E. LAINHART, Auteur ; J. HEIN, Auteur ; M. WZOREK, Auteur Année de publication : 1999 Article en page(s) : p.1117-1128 Langues : Anglais (eng) Mots-clés : Autistic disorder cognition genetics intelligence language reading disorder spelling disorder Index. décimale : PER Périodiques Résumé : In a case-control study of cognitive performance, tests of intelligence, reading, spelling, and pragmatic language were administered to the parents and siblings of 90 community-ascertained probands with autism (AU group) and to the parents and siblings of 40 similarly ascertained probands with trisomy 21 Down syndrome (DS group). The two samples were comparable for age and parents' education; both groups were well-educated and had above-average intelligence. AU parents scored slightly but significantly lower on the WAIS-R Full Scale and Performance IQ, on two subtests (Picture Arrangement and Picture Completion), and on the Word Attack Test (reading nonsense words) from the Woodcock-Johnson battery. There were no differences between AU and DS siblings. As in earlier studies, AU parents, more often than DS parents, reported a history of early language-related cognitive difficulties; we were not able to replicate this in siblings. AU parents who reported such difficulties scored significantly lower on Verbal IQ, spelling, and the nonsense reading test. AU parents without a history of early language-related cognitive difficulties often had a Verbal IQ that exceeded Performance IQ by more than one standard deviation. AU siblings with early language-related difficulties had similar findings: lower Verbal IQ, poorer spelling, and poorer reading scores, compared to AU siblings without such a history. Parents with a positive history also scored worse on a measure of pragmatic language, the Pragmatic Rating Scale, but not on measures of social-related components of the broader autism phenotype. We propose that cognitive differences in a subset of autism family members are manifestations of the language-related component of the broader autism phenotype, and separate from the social-related component. This is consistent with the hypothesis that there are several genes that may interact to cause autism which segregate independently and have distinguishable manifestations in family members. The hypothesis would be further supported by finding different patterns of genetic loci linked to autism in families where one or both parents has language difficulties.
