When we're happy, the corners of our mouths move out and up, our cheeks lift, and the skin around our eyes crinkles.當我們高興的時候,嘴角會向外上揚,臉頰也會提升,眼睛周圍的皮膚會起皺。 Researchers now say that process can be reversed: force the muscles of the face into a smile and it can make you feel a little happier, according to a report published in Nature Human Behavior.然而現在研究人員表示,這一過程可以被逆轉:一份發表在《自然人類行為》上的報告稱,強迫面部肌肉微笑,可以讓你感到更快樂。 The idea that facial expressions might influence our emotional experience, a concept known as the facial feedback hypothesis, has been long debated by psychologists.面部表情可能會影響我們的情緒體驗,這一概念被稱為面部反饋假說,心理學家長期以來對該假說爭論不休。 The mechanics of how smiling might make us feel happier aren't yet known, said the study's lead author, Nicholas Coles, a research scientist at Stanford University.該研究的主要作者、斯坦福大學研究科學家尼古拉斯·科爾斯說,微笑如何讓我們感覺更快樂的機制還不清楚。 One possible explanation is that "if you activate a smile, the peripheral nervous system tells the rest of the system that happiness is happening and it tries to catch up".科爾斯說,一個可能的解釋是,「如果你激活一個微笑,周圍的神經系統就會告訴系統的其他部分,幸福正在發生,並試圖趕上來。」 While the effect isn't strong enough to overcome something intense like depression,但科爾斯補充說,這種效果還不足以戰勝抑鬱等強烈的情緒, it provides useful insight into what emotions are and where they come from, Coles added.但它為了解情緒是什麼以及它們的來源提供了有用的見解。
