A sample (n=48) of eight-year-olds with specific language impairments is compared with age-matched (n=55) and language matched controls (n=55) on a range of tasks designed to test the interdependence of language and mathematical development. Performance across tasks varies substantially in the SLI group, showing profound deficits in production of the count(More)
Linguistic and cognitive correlates of social skill were examined in a clinically selected sample of children with communication disorders. Thirty-two children aged between 5 and 10 years were assessed using a questionnaire-based sociability scale. Specially designed measures of verbal and visuo-spatial short-term memory span were administered, as well as(More)
A sample of 4,243 residents of Manchester, England and Newcastle-upon-Tyne, England, aged 50 to 93 years, completed the Beck Depression Scale (A.T. Beck, C.H. Ward, M. Mendelson, J. Mock, & J. Erbaugh, 1961) and a battery of 6 different cognitive tests. Beck scores were low, indicating gradations of dysphoria rather than clinical depression. Beck scores did(More)
The number skills of groups of 7 to 9 year old children with specific language impairment (SLI) attending mainstream or special schools are compared with an age and nonverbal reasoning matched group (AC), and a younger group matched on oral language comprehension. The SLI groups performed below the AC group on every skill. They also showed lower working(More)
Six different cognitive tests and the Heck Depression Inventory (BDI) were given to 3,572 active community residents aged 49 to 93 years. Causes of death were ascertained for 443 who died between 36 and 3,903 days later. Subsequent survival predicted test scores during the 3,903 days and independently during Days 36 to 1,826 and Days 1,827 to 3,903. Scores(More)
PURPOSE This study identifies the outcomes and documents the longitudinal life experiences of adults who attended a specialist residential school for children with pervasive and complex developmental communication impairments. METHOD Semistructured interviews were carried out with 26 adult ex-pupils who had attended the school and the parents of 15 of the(More)
The diagnosis of specific language impairment (SLI) requires non-verbal ability to be in the normal range, but little is known regarding the extent to which general reasoning skills are preserved during development. A total of 122 children were tested; 40 SLI, 42 age-matched controls, and 40 younger language-matched controls. Deductive reasoning tasks were(More)
How does cross-linguistic variation in linguistic structure affect children's acquisition of early number word meanings? We tested this question by investigating number word learning in two unrelated languages that feature a tripartite singular-dual-plural distinction: Slovenian and Saudi Arabic. We found that learning dual morphology affects children's(More)
The United Kingdom Medical Research Council and Economic and Social Research Council have funded, since 1982, a longitudinal study of cognitive change in old age carried out on over 6000 volunteers aged between 50 and 96 years and resident in Newcastle-upon-Tyne and Greater Manchester. The Medical Research Council has guaranteed further funding until 1977.(More)
