Research in this domain falls into two primary areas: sentence comprehension and language acquisition and processing across the lifespan. The research on comprehension (Jon Brennan, Julie Boland, Richard Lewis) focuses primarily on syntactic parsing and its relationship to lexical and semantic processes. These cognitive processes are studied using multiple experimental techniques (e.g., eye-tracking, reaction time paradigms, electroencephalography/EEG, magnetoencephalography/MEG and functional magnetic resonance imaging/fMRI) and computational modeling. Research in the psychology of language across the lifespan investigates first and second language acquisition and bilingualism in children and adults (Sam Epstein, Carmel O'Shannessy, Acrisio Pires) and the relationships among language, social and cognitive factors in aging (Deborah Keller-Cohen). Faculty from other departments with related interests include Nick Ellis, Susan Gelman, Ioulia Kovelman, Frederick Morrison, Thad Polk, and Twila Tardif (all from Psychology), and Diane Larsen-Freeman (the English Language Institute and School of Education).
