Language development and disorders in autism
Pragmatic language impairment in adults with Parkinson disease
Theoretical basis of clinical language practice
My research focuses on language impairment in children and adults, with a current primary emphasis on autism spectrum disorders and Parkinson disease. I am interested in investigating the source of deficits in communicative competence in populations affected by language impairments. This basic interest has naturally led to an interest in assessment, as well as in the development of effective, evidence-based means of intervention. A primary interest is in the realm of pragmatics, which is the foundation for communicative competence. Most of my work can be seen as applied, but it is grounded in an emergent, functionalist linguistic perspective, which holds that language has evolved for functional reasons, and therefore can best be studied in naturalistic contexts of use. Thus I see clinical research as a direct contributor to theoretical models of language, language development, and disorders, and pragmatics as key to understanding the nature of language.
