The reason is not fully known, but it probably has to do with a need to restore overused brain circuits and consolidate the learning experience. “If they set it aside, get a good night’s sleep, then return to the task, they are able to get through the routine more easily,” he says. As an example, he cites the efforts of a pianist or gymnast working on a difficult passage or routine that they cannot master after hours of practice. Such findings “have important implications for learning real-life skills, including those involved with sports, playing a musical instrument, dancing, and even recovering motor functions after brain damage,” Walker believes. The longer they slept, the better they performed. She and her colleagues trained volunteers to perform a difficult visual task, then tested the trainees after they had no sleep, a 30-minute “power” nap, or a one-hour snooze. It seems as though the brain continues to learn after practicing stops, and this learning only occurs during sleep.”Īnother study, by Harvard psychology researcher Sara Mednick, backs up his conclusion. “However, a good night’s sleep after practice could be the key to perfection. “Our research demonstrates that, after a certain time, further practice may not make someone perfect at a motor task,” Walker concludes. But those retested after a good night’s sleep averaged a significantly higher 20 percent improvement in finger speed without a loss of accuracy. Those trained in the morning and re-tested 12 hours later improved their performance by an unimpressive 2 percent. Walker and his colleagues then re-tested the key-strokers 12 hours later after they did or did not sleep. After 12 minutes, they became relatively good at the task. He trained people to tap a complex series of keys on a computer keyboard as quickly as possible. That’s according to research led by Matthew Walker, an instructor in psychiatry at Harvard Medical School. Practice makes perfect, but you can get perfect faster by sleeping on it. ![]()
