If you’re hoping to master a piece of music or some other piece of information, listening to it while napping may be the way to go, according to new research conducted at Northwestern University.
Research volunteers learned how to play two artificially generated musical tunes requiring well-timed key presses. Then while the participants took a 90-minute nap, the researchers played one of the tunes that had been practiced, but not the other.
Scientists involved in the study cautioned that this does not prove that foreign language and other “learn while you sleep” recordings actually work. Rather, it shows that you can use stimuli while you sleep to solidify something you’ve already learned. What they didn’t address, however, is whether falling asleep in Algebra class is actually a good thing for high school students.
