There was this really cool experiment where researchers took participants and had them complete the tower of Hanoi task.

If you've never seen the tower of Hanoi task it's just this kind of test where you have to move rings onto different poles.

如果您从未见过河内塔任务，那就是这种测试，您必须将环移动到不同的杆子上。

Amazingly, when they were retested on the tower of Hanoi test a week later, without any practice in between, their performance improved by 40%.

令人惊讶的是，当他们在一周后再次参加河内塔测试时，中间没有任何练习，他们的表现提高了 40%。

However, if you let them try this tower of Hanoi task the next day right after doing it the day before, but you mess with their REM sleep, no such improvement is seen.

然而，如果你让他们在前一天完成后第二天尝试这个河内塔任务，但你打乱了他们的快速眼动睡眠， 就看不到这样的改善。
