The Language Learning and Processing Lab studies the acquisition, processing and representation of language. We focus on two fundamental questions: what does it mean to know language and how is this knowledge acquired? We study the learning mechanisms used by children and adults in learning first and second languages; the mechanisms involved in language processing; and the various factors - cognitive and environmental - that influence children's linguistic development. We also ask how our learning mechanisms impact the way languages are structured and change over time. We do our work in the University and at our Living Lab in the Bloomfield Science Museum.
