In the coming years, CLS researchers will be working on a major project about bilingual children. One of their goals is to determine the circumstances under which a bilingual child’s two languages influence one another. For example, one of the areas they will be examining is possessives, such as Claire’s cup. A monolingual English-speaking child may typically say Claire’s cup to describe a cup belonging to Claire, but a Dutch-English bilingual child might say the cup of Claire, analogous to the Dutch equivalent de mok van Claire. In the latter case, the structure from one language, Dutch, may influence the other, English. By studying under which conditions cross-linguistic influence occurs, CLS researchers aim to discover the differences and similarities between bilingual and monolingual language development.
