Research suggests that the growing numbers of bilingual speakers may have an advantage that goes beyond communication: It turns out that being bilingual is also good for your brain…
The idea that children exposed to two languages from birth become confused or that they fall behind monolingual children is a common misconception, says Janet Werker, a psychologist at the University of British Columbia who studies language acquisition in bilingual babies.
“Growing up bilingual is just as natural as growing up monolingual,” said Werker, whose own research indicates babies of bilingual mothers can distinguish between languages even hours after birth.
“There is absolutely no evidence that bilingual acquisition leads to confusion, and there is no evidence that bilingual acquisition leads to delay,” she said.
Werker and other researchers say the evidence to the contrary is actually quite strong. Instead of holding you back, being bilingual, they say, may actually be good for you.
