關於睡眠狀態下的人類大腦活動仍有許多待我們研究的地方，不過夢也許能給我們提供一些相關線索。本文探討大腦學習外語的方式及夢裡用外語交流對語言學習有何意義。
詞匯：language learning 語言學習
It is often said that if we dream in a foreign language, it’s a sign that we are making progress in learning that language. But is it true?
Before we can look at multilingual dreams, first we need to look at sleep. The link between sleep and language can be applied to how we learn any language, including our mother tongue. Even adults still learn about one new word every two days in their first language, but, if we are going to have a firm grasp of that new word, we need to link it to our existing knowledge. And in order to do that, we ‘need to have some sleep’, says Gareth Gaskell, a psychology professor at the University of York.
It’s during sleep that the integration of old and new knowledge happens. At night, one part of our brain – the hippocampus – takes whatever new information it soaked up in the day, and passes it on to other parts of the brain to be stored. The role that dreams play in this night-time learning process is still being studied, but ‘it’s entirely possible that during multilingual dreams, the brain is trying to connect two languages’, says Marc Züst, researcher at the University Hospital of Old Age Psychiatry and Psychotherapy in Bern, Switzerland.
So having multilingual dreams could mean that our brain is trying to master a new word or phrase, for example, but it could also have an emotional significance. Danuta Gabryś-Barker, a professor of psycholinguistics at the University of Silesia in Poland, suggests that multilingual dreams can express ‘fears and desires‘ around learning a foreign language, including the wish to be a native-like speaker or to be accepted within a certain community.
We clearly still have a lot to learn about multilingual dreams, but one thing seems certain: if you’re trying to learn a new language, you should definitely sleep on it.
