Developmental language delay from three to seven years and its significance for low intelligence and reading difficulties at age seven / Phil A. SILVA in Developmental Medicine & Child Neurology, 25-6 (December 1983)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 25-6 (December 1983) . - p.783-793 Titre : Developmental language delay from three to seven years and its significance for low intelligence and reading difficulties at age seven Type de document : Texte imprimé et/ou numérique Auteurs : Phil A. SILVA, Auteur ; Rob MCGEE, Auteur ; Sheila M. WILLIAMS, Auteur Année de publication : 1983 Article en page(s) : p.783-793 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : A large sample of Dunedin (New Zealand) children was assessed at three, five and seven years to study the prevalence and stability of language delay, and to investigate the association between language delay at each age and low intelligence and reading problems at age seven. The prevalence of specific comprehension delay, specific expressive delay, and general language delay varied from 2.0 to 4.3 per cent. General language delays were the most stable. Every type of language delay at each age, particularly earlier, general and stable delay was associated with a significantly higher prevalence of low intelligence or reading difficulties at age seven than among the total sample.

A longitudinal study of children with developmental language delay at age three: later intelligence, reading and behaviour problems / Phil A. SILVA in Developmental Medicine & Child Neurology, 29-5 (October 1987)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 29-5 (October 1987) . - p.630-640 Titre : A longitudinal study of children with developmental language delay at age three: later intelligence, reading and behaviour problems Type de document : Texte imprimé et/ou numérique Auteurs : Phil A. SILVA, Auteur ; Rob MCGEE, Auteur ; Sheila M. WILLIAMS, Auteur Année de publication : 1987 Article en page(s) : p.630-640 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : A large sample of Dunedin (New Zealand) children were assessed at age three to identify those with language delay. 2.6 per cent were defined as delayed in verbal comprehension only, 2.3 per cent as delayed in verbal expression only, and 2.3 per cent as delayed in both ('general language delay'). Most of these children, and the remainder of the sample, were assessed for intelligence, reading and behaviour problems at ages seven, nine and 11. Those in every language-delay group had significantly lower mean IQs and lower mean reading scores than the remainder of the sample. They also more often had a low IQ or a lower reading score at ages seven and nine and a lower Verbal and Full-scale IQ at 11. The groups with delayed verbal comprehension and general language delay had significantly more behaviour problems than the remainder of the sample. The group with general language delay was consistently the most disadvantaged in later intelligence, reading and behaviour. Two of the language-delay groups (comprehension and general language) had significantly higher scores on a family disadvantage index. The results of this study confirm the importance of early language delay as a predictor of lower than average intelligence and reading ability and increased behaviour problems.

Refractive Error, IQ and Reading Ability: a Longitudinal Study From Age Seven To 11 / Sheila M. WILLIAMS in Developmental Medicine & Child Neurology, 30-6 (December 1988)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 30-6 (December 1988) . - p.735-742 Titre : Refractive Error, IQ and Reading Ability: a Longitudinal Study From Age Seven To 11 Type de document : Texte imprimé et/ou numérique Auteurs : Sheila M. WILLIAMS, Auteur ; Gordon F. SANDERSON, Auteur ; David L. SHARE, Auteur ; Phil A. SILVA, Auteur Année de publication : 1988 Article en page(s) : p.735-742 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Défaut de réfraction, QI et capacité de lecture: étude longitudinale de sept à 11 ans Des enfants provenant d'un échantillon dont les défauts de réfraction cycloplégiques incluaient la myopie, la pré-myopie et l'hypermétropie ont été comparés en termes de QI et d'efficience de lecture avec un groupe d'enfants sans troubles significatifs de réfraction. A l'age de 11 ans, les QI verbaux et de performance étaient élevés chez les enfants porteurs de myopie et de pré-myopie, légèrement inférieurs chez les hypermétropes, par comparaison avec les enfants sans défauts de réfraction. Les différences dans les QI verbaux n'étaient pas attribuables seulement aux différences antérieures, au contraire des différences pour le QI de performance. Aucune différence significative dans les scores d'efficience de lecture n'a été notée à aucun age. Les auteurs concluent que la différence d'aptitude chez les enfants myopes et autres à 11 ans ne sont pas totalement explicables par des différences de milieu social ou de capacités antérieurs.
