Here is the most interesting finding: In the 24-hour retest—where all subjects had a full night of sleep—those participants who went to bed shortly after learning the words did much better than those who went through an entire day before sleeping.

And this leg up in memory was maintained on subsequent days. So if you need to remember something, try reviewing those notes just before bedtime. Instead of watching that rerun of Seinfeld you already have memorized.

I wonder if it matters that I review the notes on iPhone or iPad (as opposed to paper notes).
