In the QMUL language acquisition lab we explore language development across the lifespan, from infancy to early adulthood. We are particularly interested in how growing up in bilingual and linguistically diverse environments impacts language development. Our research explores questions like, how does the home language environment influence the acquisition of a second language? How do children learn to distinguish the speech sounds of their languages? Does the home language influence how children learn new words? To address these questions we use a combination of behavioural and neurological (EEG) measures.
