NYU Study: Seamless Code-Switching

When bilingual people switch languages mid-sentence, a practice known as code-switching, the brain does not treat the shift as unusual. Researchers at New York University found that the brain uses the same mechanism to combine words regardless of whether they come from one language or two. Their study showed that bilingual speakers process mixed-language sentences using the same neural system that builds sentences in a single language. This suggests that code-switching is neurologically seamless for bilingual brains.
