This research strand focuses on the neurocognitive and neurolinguistic study of individual multilingualism and (professional) multilingual communication across the lifespan and the effect that societal multilingualism, including multilingual policies or education, have on the development of the multilingual individual. This research strand combines four methodological approaches to study multilingualism: (1) behavioural studies to measure multilingual behaviour (e.g. language switching) in terms of speed and accuracy; (2) neuroimaging studies (e.g. fMRI) to visualize the mental processes underlying multilingual behaviour; (3) clinical studies to assess the impact of language impairment (e.g. primary progressive aphasia) and aging in multilingual populations; (4) large-scale survey and observation studies to investigate multilingual policies and education and their effect on the multilingual child.
