PURPOSE Although mean length of utterance (MLU) is a useful benchmark in studies of children with specific language impairment (SLI), some empirical and interpretive issues are unresolved. The authors report on 2 studies examining, respectively, the concurrent validity and temporal stability of MLU equivalency between children with SLI and typically developing children. METHOD Study 1 used 12...

Purpose This sentence processing experiment examined the abilities of children with specific language impairment (SLI) and children with typical language development (TD) to establish relations between pronouns or reflexives and their antecedents in real time. Method Twenty-two children with SLI and 24 age-matched children with TD (7;3-10;11 [years;months]) participated in a cross-modal pictu...

Specific language impairment (SLI) occurs when children present language maturation, at least 12 months behind their chronological age in the absence of sensory or intellectual deficits, pervasive developmental disorders, evident cerebral damage, and adequate social and emotional conditions. The aim of this study was to classify a group of children according to the subtypes of SLI and to correl...

Specific language impairment (SLI) is a multifactorial neurodevelopmental disorder which occurs unexpectedly and without an obvious cause. Over a decade of research suggests that SLI is highly heritable. Several genes and loci have already been implicated in SLI through linkage and targeted association methods. Recently, genome-wide association studies (GWAS) of SLI and language traits in the g...

OBJECTIVE For phenotyping specific language impairment (SLI) in kindergarten children in clinical practice and research issues, we need a valid diagnostic method for dichotomous classification (language impaired, normal developing). PATIENTS AND METHODS 27 kindergarten children belonged to SLI-group, 36 to control-group. The diagnostic accuracy of a composed language test battery was examined...
