The Benefits of Being Bilingual

At one time being bilingual was thought to slow down brain development, although it is now known to have many benefits. Aside from professional and social benefits, studies show that the process of learning a second language actually strengthens some areas of the brain.

To start off with, a study done at the University of British Columbia shows that babies exposed to two languages before birth don’t confuse the languages. Moreover, it showed that the effort it takes to keep the languages separate improves perception.

The benefits aren’t only for people who grow up bilingual, however. Anyone who learns a second language during their lifetime will have certain advantages. For one, Swedish scientists found that the brain grows during language learning, particularly the area where memories are created.

Not only does the brain grow, but language learners also improve in many areas. They are good at multitasking while paying detailed attention to each task. Additionally they strengthen their math skills, listening skills, ability to focus, problem-solving skills, reading and vocabulary in their native language, and their memory increases. In the area of math, a study done at the University of Washington shows that bilinguals solve new math problems half a second faster than monolinguals.

Language learning also has huge benefits for old age. Brian Gold of the University of Kentucky did a study comparing the ability of bilingual seniors and monolingual seniors to do an attention-switching task. Usually this skill fails with age. However the bilingual seniors performed better than the monolinguals, and their brains worked less hard and more efficiently.

Neuroscientists (神经系统科学家) think that having more brainpower at an older age helps protect us from Alzheimer’s. Current medication for Alzheimer’s only delays it for 6-12 months, while learning a new language delays it for 4-5 years. Again, this is not only for people who learn a second language from birth. Even if you don’t learn another language until after middle age it helps. Language learning keeps your brain active and “fit”.
