Bilingualism: Language and Cognition is a quarterly peer-reviewed academic journal of linguistics focusing on the study of multilingualism, including bilingual language competence, perception and production, bilingual language acquisition in children and adults, neurolinguistics of bilingualism (in normal and brain-damaged populations), and non-linguistic cognitive processes in bilinguals. The journal is published by Cambridge University Press and was co-established by François Grosjean in 1998.
