Language Development (COMD 2339)
Theories and descriptions of typical development of language from infancy through adolescence.
Dr. Castilla-Earls' current research is oriented to a) find grammatical markers of language impairments that are accurate and stable across various levels of bilingual proficiency, b) examine current assessment practices in monolingual and bilingual children, and c) promote the systematic use of research-based practices in clinic and educational settings.
