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.

Physical development of hyperactive boys / Rob MCGEE in Developmental Medicine & Child Neurology, 27-3 (June 1985)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 27-3 (June 1985) . - p.364-368 Titre : Physical development of hyperactive boys Type de document : Texte imprimé et/ou numérique Auteurs : Rob MCGEE, Auteur ; Phil A. SILVA, Auteur ; John BIRKBECK, Auteur Année de publication : 1985 Article en page(s) : p.364-368 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Anthropometric data were collected on groups of seven-year-old Dunedin (New Zealand) boys, identified as hyperactive-only, aggressive-hyperactive, aggressive-only and non-aggressive/non-hyperactive. Measures taken included stature, weight, skeletal maturity, mid-upper arm circumference, triceps and subscapular fatfolds and body-mass index. The hypothesis that hyperactive-only boys would show delayed maturation, as indicated by lower bone-age, was not confirmed. However, these boys had significantly smaller mid-upper arm circumference, triceps fatfold and body-mass index than the other groups. The results suggest that body leanness may discriminate 'pure' hyperactive boys from aggressive-hyperactive boys.
