The Children's Nonword Repetition Test (CNRep) was given 39 children with persistent language impairment (LI), 13 with a history of having received speech-language therapy (resolved LI), and 79 controls, all aged from 7 to 9 years. The children with LI were twins who had participated in a previous genetic study. Children with resolved LI, as well as those(More)
Language and literacy skills were assessed in 83 8 1/2-year olds whose language development had been impaired at 4 years of age. Provided that language problems had resolved by age 5 1/2 years, literacy development was normal, but many of the children who still had verbal deficits at 5 1/2 years of age did have reading difficulties and persisting oral(More)
The literacy skills of 56 school leavers from the Bishop and Edmundson (1987) cohort of preschoolers with specific language impairment (SLI) were assessed at 15 years. The SLI group performed worse on tests of reading, spelling, and reading comprehension than age-matched controls and the literacy outcomes were particularly poor for those with Performance IQ(More)
This study investigated the link between expressive phonological impairments, phonological awareness, and literacy. Previous investigations of literacy skills in children with speech impairments have given mixed results; here we considered whether presence of additional language impairments or severity of the speech impairment was an important prognostic(More)
Phonological skills, language ability, and literacy scores were compared for four groups: 19 children with mild-to-moderate sensorineural hearing loss (SNH), 20 children with specific language impairment (SLI), 20 controls matched on chronological age to the SNH group (CA), and 15 controls matched on receptive vocabulary level to a subset of the SLI group(More)
Children with diagnoses of either autism or Asperger's syndrome were matched on measures of verbal mental age with nonautistic control children. They were tested on their abilities to process both facial and nonfacial stimuli. There were no significant differences between the low ability autistic and control groups, but the high ability autistic and(More)
This paper reports a longitudinal follow-up of 71 adolescents with a preschool history of speech-language impairment, originally studied by Bishop and Edmundson (1987). These children had been subdivided at 4 years into those with nonverbal IQ 2 SD below the mean (General Delay group), and those with normal nonverbal intelligence (SLI group). At age 5;6 the(More)
OBJECTIVE Autism is a diagnostic spectrum of variable severity, with significant comorbidity. No existing standardized interview measures autistic features dimensionally. The authors aimed to develop a parental autism interview that could be administered to unselected clinical and general population samples that measures both symptom intensity and(More)
Three groups of right-handers were identified using the Edinburgh Handedness Inventory. Exclusive strong right-handers (Rs: N = 18) reported that they always used the right hand for eight or more of the 10 activities, and usually used the right hand for the remainder. Exclusive weak right-handers (Rw: N = 15) usually used the right hand for three or more(More)
