“The limits of my language mean the limits of my world.”- Ludwig Wittgenstein, philosopher
Did you know that 56% of all Europeans are bilingual, while Americans and British are at the bottom of the league with only about 20%? Actually, Bill Gates feels “pretty stupid” because he is monolingual, but that certainly did not prevent him from becoming a billionaire!
Numbers and anecdotes aside, being bilingual makes you smarter, according to many research studies. Basically, your brain is more active and your cognitive skills improve as you learn new languages. As an added bonus, you may actually be able to delay the onset of dementia in old age. Here are the main points from the most important studies on the advantages of being bilingual.
Bilinguals are sharper thinkers
Samuel Beckett, the great Irish playwright, is a superb example. Although a native English speaker, he decided to write all his first drafts in French, as he was bilingual. He then translated them back into English. He explained that this forced him out of his usual, predictable writing style habits. Using the second language forced him to be much more critical and aware of what he was writing.
Researchers at the University of Chicago wondered if Beckett was an exceptional case or if bilinguals really are sharper thinkers. Their research showed that bilinguals were indeed less biased in making their decisions and were sharper when having to make choices as to style and selection of vocabulary. They were, in a way, forced to think outside the box. They were also better at making more rational decisions.
Bilinguals have better working memory
Ellen Bialystok is a researcher at York University, Toronto. She and her colleagues set out to show that bilinguals have certain advantages in mental processing. They found that bilinguals are better at switching their attention when multi-tasking and are also better at paying attention in general. It did not matter whether the tasks were connected to language or not.
This type of mental processing is known as executive control. This control plays a vital part in childhood academic achievement which in turn benefits overall health and well-being. The researchers also noticed that bilinguals are better at sifting out irrelevant information since they frequently have to deal with interference from other languages.
Bialystok conducted another study which showed that this great advantage extended well into old age and was a factor in helping to stave off dementia. The faster reaction and better memory of the elderly participants was a marked feature of the bilinguals in the study.
“We have even found that bilinguals with Alzheimer’s disease maintain surprisingly good ability to access names in a non-dominant language.” – Tamar Gollan, University of California, San Diego
Bilinguals have more gray matter
As we know, the more gray matter we have in our brains the better, as it helps us process information we receive, especially for intellectual activity. Researchers at the Georgetown University Medical Center in Washington, DC also found that bilinguals (Spanish/English) had more gray matter in their brains than those who were using English/ ASL (American Sign Language).
“Unlike the findings for the Spanish-English bilinguals, we found no evidence for greater gray matter in the ASL-English bilinguals.” – Dr. Olumide Olulade, lead author of the above study.
The management of two spoken languages was regarded by researchers as being a key factor in the growth of gray matter. It is generally accepted that our brains adapt as a result of new experiences.
They also observed that London taxi drivers have more gray matter too, although that has more to do with their spatial navigation skills rather than knowing two or more languages.
Are you ready to start learning another language?
Most of the research studies indicate that you do not have to be bilingual from childhood. Even learning a second language in later life can give you many of the advantages cited above. It is time to start talking to the world.
