Learn In Your Sleep, Researchers Say

U.S. researchers suggest sleeping can help us remember things we have just learnt. A team from Northwestern University report that a 90-minute nap can help people learn a new skill. The article on their research is published in the June edition of the journal "Nature". The scientists say: "Information acquired during waking can be reactivated during sleep, promoting memory stabilization." Test volunteers practised musical tunes before and after a short sleep. During the nap, the researchers played one of the tunes the volunteers had practised, but not the other. The team found that the participants made fewer errors when playing the melody that had been played while they slept.

Study co-author Dr Paul J. Reuber points out the research might not work with learning a foreign language while you sleep. He said: "The critical difference is that our research shows that memory is strengthened for something you've already learned." He added: "Rather than learning something new in your sleep, we're talking about enhancing an existing memory by re-activating information recently acquired." However, Dr Reuber did say there were possibilities for language learners: "If you were learning how to speak in a foreign language during the day, for example, and then tried to reactivate those memories during sleep, perhaps you might enhance your learning," he said.
