This study examined the association of chronological age (CA) with syntax and vocabulary comprehension in 102 children and adolescents with mental retardation. Results indicated that intelligence scores accounted for 55% and 29% of the variability of syntax and vocabulary scores, respectively. Introduction of CA into the regression equation…

This study used a performance-based model to investigate the impact of discourse demands on the pattern of morphosyntactic deficits exhibited by 10 children with specific language impairments (SLI). Findings suggest distinct deficit profiles for subgroups of children with SLI differing in receptive language abilities, not evident when syntactic…

The syntactic development of preschoolers (n=22) who later became disabled readers was compared to that of similar children who became normal readers. Expressive and receptive syntactic abilities were examined from age 30 to 60 months. The dyslexic group was poorer on all measures until age five, when both groups exhibited similar syntactic…
