It’s well-known that being bilingual has obvious advantages. Some of which are that it allows you to take advantage of new experiences new conversations. 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.
We took a group of children in the United States, ages 4 to 6, from different linguistic backgrounds, and presented them with a situation in which they had to consider someone else’s perspective to understand her meaning. For example, an adult said to the child: “Ooh, a small car! Can you move the small car for me?” Children could see three cars — small, medium and large — but were in position to observe that the adult could not see the smallest car. Since the adult could see only the medium and large cars, when she said “small” car, she must be referring to the child’s “medium.”
We found that bilingual children were better than monolingual children at this task. If you think about it, this makes intuitive sense. Interpreting someone’s utterance often requires attending not just to its content, but also to the surrounding context. What does a speaker know or not know? What did she intend to convey? Children in multilingual environments have social experiences that provide routine practice in considering the perspectives of others: They have to think about who speaks which language to whom, who understands which content, and the times and places in which different languages are spoken.
Interestingly, we also found that children who were effectively monolingual yet regularly exposed to another language — for example, those who had grandparents who spoke another language — were just as talented as the bilingual children at this task. It seems that being raised in an environment in which multiple languages are spoken, rather than being bilingual per se, is the driving factor.
