The mission of the lab is to foster research in child language development and disorders. The disorder that is primarily studied is Specific Language Impairment (SLI). Although all aspects of the SLI condition can be studied within this lab, our work often focuses on these children’s difficulties with vocabulary and grammar. Many who work in this lab are also interested in children’s acquisition of different Louisiana dialects of English and the impact of these dialects on theoretical models of language development and disorders, language testing, and academic achievement. Language development of children reared in poverty and the role of prevention services for low-income families are other areas of research that we actively pursue.
