Researchers presented their newest studies last month at a meeting of the American Association for the Advancement of Science. The latest evidence shows that being bilingual does not necessarily make people smarter. But researcher Ellen Bialystock says it probably does make you better at certain skills. Imagine driving down the highway. There's many things that could capture your attention and you really need to be able to monitor all of them. Why would bilingualism make you any better at that? And the answer, she says, is that bilingual people are often better at controlling their attention -- a function called the executive control system.
