The more languages you speak, the easier it is for the brain to learn more

TOKYO, Japan — For those of us confined to knowing just one language, learning an additional dialect can feel impossible. Many bilinguals, however, marvel at the language skills of multilinguals (individuals fluent in three or more languages). Interestingly, a new Japanese study reports the collection of ground-breaking neurological evidence indicating lingual skills are additive. In other words, the more languages you speak, the easier it will be to learn another.

These findings potentially explain why one person fluent in English and Spanish may be in awe of someone who can speak German, Russian, and English. Meanwhile, that trilingual individual can’t believe it when he or she meets someone else who can speak German, Italian, French, English, and Russian.

“The traditional idea is, if you understand bilinguals, you can use those same details to understand multilinguals. We rigorously checked that possibility with this research and saw multilinguals’ language acquisition skills are not equivalent, but superior to those of bilinguals,” says study co-author Professor Kuniyoshi L. Sakai from the University of Tokyo in a release.

Researchers measured the brain activity of 21 bilingual and 28 multilingual study participants as each person attempted to decipher words and sentences written and spoken in Kazakh — a language no participant was familiar with at all. All subjects were native Japanese speakers, with most also being fluent in English. Some of the multilingual participants could speak up to five languages including Chinese, Russian, Korean, and German.

A ‘lost’ first language can influence how your brain processes sounds

Offering further proof of the impressionable nature of the newborn brain, researchers studying the influence of early language have discovered a life-long impact.

In a paper published this week in Nature Communications, scientists from McGill University and the Montreal Neurological Institute explain how even brief exposure to language permanently wires how our brains process sounds and second languages later in life. So even if you can’t remember a lick of the French your parents spoke to you as a newborn, that brief exposure to the dialect makes your brain’s handling of a second language different from someone who has spoken or heard only one language.
