Specific Language Impairment (SLI) is a communication neurodevelopmental disorder that manifests at the age of 3-5 years when child lags his chronological speech development by one year in absence medical, environmental, and psychological risk factors. SLI has been known to be highly heritable. Many studies have demonstrated different genes loci implicated through linkage studies, commonest whi...

Specific language impairment (SLI) is defined as an inability to develop appropriate language skills without explanatory medical conditions, low intelligence or lack of opportunity. Previously, a genome scan of 98 families affected by SLI was completed by the SLI Consortium, resulting in the identification of two quantitative trait loci (QTL) on chromosomes 16q (SLI1) and 19q (SLI2). This was f...

BACKGROUND Much evidence has accumulated to indicate memory deficits in children with specific language impairment. However, most research has focused on working memory impairments in these children. Less is known about the functioning of other memory systems in this population. AIMS This study examined procedural and declarative memory in young children with and without specific language imp...

BACKGROUND The ability of children with Specific Language Impairment (SLI) to use and comprehend closed-class words. AIM Acknowledging the increasing search for the characterization of linguistic performance of this population in different languages, as well as the findings of international literature that stress the difficulty of these children in using closed-class grammatical morphemes, th...

PURPOSE The author examined the influence of sentence type, clause order, and verb transitivity on the accuracy of children's past tense productions. All groups of children, but especially children with specific language impairment (SLI), were predicted to decrease accuracy as linguistic complexity increased. METHOD The author elicited past tense productions in 2-clause sentences from 5- to 8...
