6-minute catnap sharpens memory - Behavior- msnbc.com

A research study shows that napping improves memory. When three groups were told to study a list of words, and afterwards one group was assigned to play video games, and the other two were told to take 6 and 35 minute naps respectively, it was found that “nap takers consistently remembered more words. On average, six-minute nappers remembered one word more than the video game players, while people taking the longer naps remembered two words more.”
