A neuroscientist explains how being bilingual makes your brain more robust

Summary

Mariano Sigman, a neuroscientist and author, discusses the benefits of raising children in a bilingual environment. He highlights that bilingualism enhances cognitive control, which is a crucial brain function that helps with attention, persistence, and managing multiple tasks. Sigman emphasizes that bilingual children tend to have better cognitive abilities, leading to improved performance in school, better job prospects, and overall healthier lives. Contrary to misconceptions, bilingualism does not delay linguistic development but instead promotes intelligence and broadens cultural understanding.
