Most people accept that when we speak more than one language, our perception of the world expands and becomes richer. Languages are linked to culture and often have unique meaning, which provide us with a better understanding of our world. We also assume that being bilingual is an advantage in the professional world, opening up opportunities to work for multi-national companies or doing business abroad. But when we speak a second language, there is still another advantage that you might not even know about!
Often called “the bilingual edge”, many language researchers and scientists who have studied the cognitive effects of learning more than one language tend to agree that our brains are affected by it. To what degree, however, and in what way, is still a topic of debate.
In years past, for example, it was commonly believed that bilingual children were at a disadvantage when it came to verbal development and even their IQ score. Today, the opposite belief is more common, and many parents are making sure their children learn a second language from the earliest age. You may know parents who hire foreign nannies or send their children to a language immersion school. These parents are seeking to give their child “the bilingual edge”, which is not just about improving intellectual ability, but also cognitive development.
