One of the bits of evidence that supports this is that when people are trying to solve a problem, they, um, typically have increased muscular activity in the throat region.

一个能证明这一点的证据就是，当人们试图解决某个问题时，他们喉部的肌肉活动常常会增加。

That is, if you put electrodes on the throat and measure muscle potential—muscle activity—you discover that when people are thinking, like if they're diligently trying to solve a problem, that there is muscular activity in the throat region.

如果你把电极放在喉咙上然后测量肌肉电位——肌肉活动——你会发现当人们思考的时候，比如他们试图解决某一个问题时，在喉部有肌肉活动。
