BEING bilingual has some obvious advantages. Learning more than one language enables new conversations and new experiences. But in recent years, psychology researchers have demonstrated some less obvious advantages of bilingualism, too. For instance, bilingual children may enjoy certain cognitive benefits, such as improved executive function — which is critical for problem solving and other mentally demanding activities. Now, two new studies demonstrate that multilingual exposure improves not only children’s cognitive skills but also their social abilities. One study from my developmental psychology lab — conducted in collaboration with the psychologists Boaz Keysar, Zoe Liberman and Samantha Fan at the University of Chicago, and published last year in the journal Psychological Science — shows that multilingual children can be better at communication than monolingual children.(more)
