分辨真假笑容—LIE to Me 试试看

    它是热播美剧Lie to Me 的原型Paul Ekman教授的一项研究,你可以亲自测试一下自己辨别真假笑容的能力,然后再来阅读下面的文字!(小编我的自大已经被打击了!)

这个研究结果显示,很多人分辨虚假笑容的能力是出奇的差劲。这可能是因为当人不知道别人的真实感受时,人际交往会相对更容易一些。

尽管假笑常常看上去非常类似于真正的微笑,但它们实际上是略有不同,因为它们是由不同的肌肉控制,这些肌肉也同样受大脑的不同神经所控制。

人可以根据自己的意志展露虚假的笑容,大脑的意识部分会创造脑部信号激起脸颊两侧的肌肉收缩,这样的收缩使嘴角朝外。

相反真诚的微笑来自于大脑的无意识部分,自动化的程度较高。当人们感到快乐时,这种情感信号经过大脑加工后传递出来。脸颊部肌肉上提,连带眼部的轮匝肌和眼眶会产生褶皱,眉毛微微下沉。

当人刻意假笑时,眼睛周围有时也出现线条,脸颊上提,眼睛周围的样子看上去也像是真实的笑容。但是仍然有几个关键的迹象帮我们区分出这些不是真正的微笑。例如,当一个微笑是真心的时候,眼睛盖-眼和眉毛之间的肌肉部和眼皮-会向下移,而最后眉毛的也会微微下沉。

科学家区分真正的和假笑利用编码系统被称为面部动作的编码系统(FACS),它由加利福尼亚大学的Paul Ekman教授和肯塔基州大学的Wallace V. Friesen博士共同设计。

 

原文如下:(译者:阎兰)

Most people are surprisingly bad at spotting fake smiles. One possible explanation for this is that it may be easier for people to get along if they don't always know what others are really feeling.

Although fake smiles often look very similar to genuine smiles, they are actually slightly different, because they are brought about by different muscles, which are controlled by different parts of the brain.

Fake smiles can be performed at will, because the brain signals that create them come from the conscious part of the brain and prompt the zygomaticus major muscles in the cheeks to contract. These are the muscles that pull the corners of the mouth outwards.

Genuine smiles, on the other hand, are generated by the unconscious brain, so are automatic. When people feel pleasure, signals pass through the part of the brain that processes emotion. As well as making the mouth muscles move, the muscles that raise the cheeks the orbicularis oculi and the pars orbitalis also contract, making the eyes crease up, and the eyebrows dip slightly.

Lines around the eyes do sometimes appear in intense fake smiles, and the cheeks may bunch up, making it look as if the eyes are contracting and the smile is genuine. But there are a few key signs that distinguish these smiles from real ones. For example, when a smile is genuine, the eye cover fold - the fleshy part of the eye between the eyebrow and the eyelid - moves downwards and the end of the eyebrows dip slightly.

Scientists distinguish between genuine and fake smiles by using a coding system called the Facial Action Coding System (FACS), which was devised by Professor Paul Ekman of the University of California and Dr Wallace V. Friesen of the University of Kentucky.
