微笑是如何控制我们所有人的

In the image at right, Duchenne applies electrodes to his cooperative subject in order to stimulate the contraction of the smile muscle (zygomaticus major) that pulls the corners of the mouth up when we smile. His subject is clearly enjoying this. Duchenne's jolt of electricity activates the smile muscle around the mouth, but the gentleman's eyes are also smiling, as seen by the creases formed just to the side of his eyes so the happiness comes from inside. When Duchenne first applied the electricity, only the smile muscle around the mouth was activated; he realized that it didn't look like a true, natural smile, so he told this gentleman a joke to make his eyes smile as well.

在右边的图片上，杜氏对他的合作的实验对象运用电极，以刺激微笑肌（主要是颧肌）的收缩，它在我们微笑时拉起我们的嘴角使其上扬。他的实验对象显然正在享受这个。杜兴的电流激活嘴周围的微笑肌肉，但这位绅士的眼睛也在笑，从只在眼睛周围形成的褶皱中透出了快乐。当杜氏首次运用电流时，只有嘴周围的微笑肌肉被激活;他意识到它看起来并不像一个真正的，自然的微笑，所以他给这位先生讲了个笑话，使他的眼睛也笑了。

Paul Ekman, who led the scientific investigation of facial expressions in the twentieth century, has shown that Duchenne was right. Few of us can fake an eye smile. If you're sitting across from a new business associate and he smiles at you but you're still not sure if you should sign off on a new business venture, look at those little lines around the outside of his eyes. If they wrinkle up like crow's feet, then his smile is a real signifier of pleasure or happiness. The absence of smiling eyes should alert you that your new associate's smile is not necessarily as friendly as it looks.
