To test this, researchers looked at 2 different learning techniques, massed practice and distributed practice.

为了验证这一点，研究人员研究了两种不同的学习技巧，集中练习和分散练习。

Distributed practice forces you to do this repeatedly, while creating necessary space in between.

分散练习迫使你重复进行这样的过程，同时在两者之间创造必要的间隔。

In fact, the only two things out of the 10 that showed up as high utility, that was practice testing and distributed practice or space repetition.

事实上，这 10 件事中只有两件事表现出高实用性，那就是练习测试和分布式练习或空间重复。

Distributed practice is when you spread the learning process out over several shorter sessions, by studying the same thing each time, you actually absorb the information, so you can recall it whenever necessary.

分散练习就是当你把学习过程分散到几个较短的阶段，每个阶段都学习同样的东西，你真正地吸收了信息，那么你就可以随时回忆起来。
