Nap, Don't Cram, Before Tests

We've heard before that REM sleep is important to solidifying memories and experiences in your brain between days but what if you need to learn something in the morning and then use it the same evening? Jonah Lehrer filters some new research which suggests that mid-day naps which include REM sleep are very effective at bumping your testing results (in word association tests, at least). How much more effective than a pre-nap performance? Try 40%.

I suppose this means that your best bet before a test is not cramming, as usually attempted, but napping. Yet another win for naps. ]
