Children from low-income environments are at increased risk of developing language delays which can negatively affect later academic and social outcomes. As children age, deficits between children with language delays and their typically developing peers continue to widen. In order to prevent future disabilities, efficient early language screening…

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…

Approaches to the analysis of utterance disruptions are reviewed, and a system is proposed for analyzing disruptions in spontaneous language, with four disruption categories (pauses, repetitions, revisions, and orphans). Use of the system is illustrated using language samples from 10 traumatically brain-injured and 10 normally developing speakers…

A study examined the identification of distinct subgroups of learning-disabled young adults based on their ability to generate written language. Two subgroups of learning-disabled college students, the language strong/visually weak (N=22) and the visually strong/language weak (N=10), were identified based on evaluation of 32 essays. Subjects were…
