How Language and Cognition Come Together in the Developing Bilingual Brain

Early life experiences impact children’s cognition and brain development. In this talk, I propose that bilingualism provides children with experiences that alter how the brain is functionally organized. The work uses functional near-infrared spectroscopy (fNIRS) to measure brain activity during attentional control tasks in bilingual and monolingual school-age children and infants. I demonstrate that the brain regions necessary for language processing interact with, and re-organize, attentional mechanisms in the bilingual brain, and that these changes derive from dual-language experiences. To conclude, I outline how these changes may be driven from social interactions, and how they may support socio-emotional development and academic success.
