Strengthen Existing Memories While You Sleep

Learning during sleep is a long sought goal.   Exciting new research from Northwestern University reveals that you can but there is a hitch. You can only strengthen existing memories not learn something new.

They demonstrated the effect for learning to play a new tune. Subjects practiced learning two new tunes on a key board and then took a 90-minute nap. During the nap they were exposed to one tune but not the other. Upon awakening they committed fewer errors playing the tune they heard while sleeping.

The researcher speculate how this might be applied more broadly:

“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.”

I am interested to hear from readers that have experimented with learning during sleep.  Did you learning any new?
