15种肢体语言解读 学会这些你也懂“读心术”

12.如果一个人眉头没有向内聚拢上抬，那么他可能没有看上去那么悲伤

Psychologist Paul Ekman uses the term "reliable muscles" for the muscles in the face that you can't contract voluntarily.
心理学家保罗•艾克曼用“可靠的肌肉”来形容人们无法自如控制的面部肌肉。

If you observe a person expressing sadness both verbally and facially, but the inner corners of his eyebrows are not going up and in, he may not be experiecing sadness at all. He's unable to contract these muscles voluntarily despite his best efforts.
如果你发现有人用语言和面部表情表达悲伤，但是他的眉头没有上抬聚拢，那么他可能根本不难过。尽管他已经尽了最大努力，但是他还是无法自如地收缩这些肌肉。
