Worldwide, there are more children who grow up learning multiple languages than children learning only one. And yet monolingualism is often taken as a starting point, for example in school. Research by linguist Elly Koutamanis shows that the two languages of a bilingual child are always active in their brain. "A child can benefit from this bilingual knowledge at school." Koutamanis will receive her Ph.D. on language interaction in bilingual children on 22 March.
