This study examined nonword repetition performance in a population-based sample of school-age children. A total of 581 second graders who were participating in a longitudinal, epidemiologic investigation of specific language impairment (SLI) were administered the Nonword Repetition Task (NRT) developed by Dollaghan & Campbell (1998). Performance was(More)
PURPOSE Children with language impairment (LI) often perform below the level of typically developing peers on measures of both processing speed and working memory. This study examined the relationship between these 2 types of measures and attempted to determine whether such measures can account for the LI itself. METHOD Fourteen-year-old children with LI(More)
PURPOSE To examine concurrently and retrospectively the language abilities of children with specific reading comprehension deficits ("poor comprehenders") and compare them to typical readers and children with specific decoding deficits ("poor decoders"). METHOD In Study 1, the authors identified 57 poor comprehenders, 27 poor decoders, and 98 typical(More)
The purpose of this study was to investigate the impact of speaking rate variations in the linguistic input provided to children during a novel word learning task. Thirty-two school-age children participated in this investigation, including 16 children with specific language impairment (SLI) and 16 normal language (NL) controls matched on mental age (MA).(More)
Children with specific language impairment (SLI) are known to display persistent difficulties with inflectional morphology--in particular, the overuse of unmarked grammatical forms (i.e., zero-marking). Yet, several recent studies have shown that English-speaking children with SLI, like their normal language peers (NL), demonstrate a considerable degree of(More)
Standardized calibrated severity scores (CSS) have been created for Autism Diagnostic Observation Schedule, 2nd edition (ADOS-2) Modules 1-4 as a metric of the relative severity of autism-specific behaviors. Total and domain CSS were created for the Toddler Module to facilitate comparison to other modules. Analyses included 388 children with ASD age 12-30(More)
This study characterized early language abilities in toddlers with autism spectrum disorders (n = 257) using multiple measures of language development, compared to toddlers with non-spectrum developmental delay (DD, n = 69). Findings indicated moderate to high degrees of agreement among three assessment measures (one parent report and two direct assessment(More)
This study examined the longitudinal associations between parent verbal responsiveness and language 3 years later in 34 toddlers with a diagnosis of an autism spectrum disorder. Parent-child play samples were coded for child engagement and communication acts and for parent verbal responsiveness. Measures of responsive verbal behaviors were used to predict(More)
PURPOSE This study presents an analysis of language skills in individuals with Noonan syndrome (NS), an autosomal dominant genetic disorder. We investigated whether the language impairments affecting some individuals arise from deficits specifically within the linguistic system or whether they are associated with cognitive, perceptual, and motor factors.(More)
Constructive comprehension abilities were compared in a group of 12 language-disordered children (second graders) and two groups of children acquiring language normally (12 second graders matched to the language-disordered subjects on nonverbal cognitive skills and 12 kindergartners matched on language comprehension). Differences were examined in(More)
