When a video of someone speaking is paused, the stationary¹ image of the speaker typically appears less flattering than the video, which contained motion. We call this the frozen face effect (FFE).

 

视频中某人正在说话的画面被暂停时，静止画面中的人通常都没有视频播放时动态画面中的人好看。这种现象就叫做“冻脸效应”（FFE）。

 

While researchers aren’t completely certain, one possibility is that, evolutionarily, we’re more accustomed to seeing dynamic faces than static ones. Since it’s easier for our brains to recognize a moving face, and since it requires less work, the result could mean a higher perceived attractiveness.

 

研究人员也不是很确定形成这一现象的原因，不过有一种可能的解释是，人类在进化过程中已经习惯了接收动态的脸部画面。因为大脑更容易识别动态的脸部画面，这一识别过程也不需要费太多精力，所以接收到的动态脸部画面的魅力指数也就要高一些。
