In English, tones do not change the meaning of words, but in Mandarin, they do. Regardless, bilingual babies learn languages faster than monolingual babies.
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.
