Want Sharper Memory, Take a Nap
The latest research found that if you take a daytime nap, and you might awaken with a more sharper memory. That’s what occurred in a new napping study that involved thirty-three undergraduate students. At first, the students took three different tests of their short-term memory.
The first test, they had to learn and memorize pairs of uncorrelated words, such as “alligator” and “cigar.” In other test, they had to navigate and remember a maze shown on a computer display. And in the last test, the students had to re-create a complex drawing onto a piece of paper, and then sketch the drawing from memory.
Next, half of the students take daytime nap for about forty-five minutes, while other students watched TV. Lastly, all of the students repeated the three memory tests. Napping boosted scores on the word-pair test, but not the other two tests.
A closer view the test scores shows that on all three tests, students with the highest scores before napping were the ones with the biggest gains in their post-nap test scores. So if they didn’t actually absorb information before their nap, naps did not as if by magic make the information bury in.
Matthew Tucker, PhD, and William Fishbein, PhD, report their findings in today’s edition of Sleep. Tucker and Fishbein work in the psychology department of the City College of the City University of New York.
