ABSTRACT
We examine a type of language contact, that which is grounded in bilingualism, and discuss the various experimental methodologies that have been employed to study the consequence of having two languages in a single mind. First, we review central findings in bilingual language processing. Next, we describe the most common behavioural research methods and tools from cognitive neuroscience that have been used to uncover the different levels of language at which cross-language interactions have been observed in bilingual speakers. We conclude with suggestions that we view as critical to advance the study of bilingualism in lab-based contexts.
