有一项研究是用鸽子进行的：实验中，研究人员试图把 MSR 归结为条件反射，也就是说，他们声称在镜子里认出自己的能力是可以习得的。

There was a study using pigeons, where researchers attempted to reduce MSR to a matter of conditioning, that is, they claimed that the ability to recognize oneself in a mirror could be learned.

“不管什么时候，只要看到街上有排队的，条件反射似的我就也想去排，因为我知道那里肯定也有我们家需要的东西，”王老先生这么说。

"Whenever I saw a queue on the street I had a conditioned response to queue, because I knew that there must be something my family needed," Wang said.

说“你好”的时候，是不可能不面带微笑的，而且能一个传给另一个，正如敲击膝盖引起的条件反射。

It's impossible to say hello without smiling. One leads to the other just as a tap causes a knee jerk.
