Speech and Hearing Sciences Faculty Publications and Presentations

Background

Languages vary in their syntactic (e.g. word order in sentences), lexical (e.g. presence of specific word classes), and morphological (e.g. inflectional or derivational forms of words) properties. This cross-linguistic variation in language typology influences the manifestation of agrammatic symptoms. However, most theoretical models of agrammatism are based on English and a few European languages, limiting their generalizability. This narrow focus neglects the rich syntactic, lexical and morphological variations available in languages globally. Clinically, the lack of language-specific characteristics of agrammatic impairments limits translational potential for precise and improved diagnosis. The Aphasia in South Asian Languages (ASAL) project addresses this …
