People use more facial expressions than thought 人类表情丰富超乎你想象 共有21种表情 When youre feeling one of those combination emotions, like sadly angry or happily disgusted, it shows on your face in a unique way, a new study shows. 据LiveScience网站报道，当人们感受到上述复合情感时，例如悲愤或者又开心又讨厌，这些情感就会以一种特别的方式呈现在脸上。 In fact, there may be at least three times more recognizable human facial expressions than previously thought, the researchers said. 研究人员表示，事实上，可识别的人类面部表情的数量至少是之前所认为的三倍之多。 In a new study, researchers defined 21 facial expressions that we use to convey our emotions, and found that a computer model could tell them apart with a high degree of accuracy by looking for small changes in facial muscles. 在一项新研究中，研究人员定义了21种用于传递感情的面部表情，并发现，借助某种计算模型可以区分面部肌肉的微变化，从而准确分辨这些表情。 Among these facial expressions were the six, long-recognized basic emotions — happy, sad, fearful, angry, surprised and disgusted — but also 15 others, which were a combination of these basic feelings. For example, a person may show that they feel happily surprised, or angrily surprised, said the researchers, calling such feelings compound emotions. 这些表情中，最早为人所知的六种基本情感分别是，喜悦、悲伤、害怕、愤怒、和厌恶。另外15种则是这些基本情感的组合。例如，某人可能表现出惊喜，或者惊怒。研究人员将其统称为复合情感。 This extended library of facial expressions of emotions may be useful in studying human brain and social communication, as well as in the design of computer systems that can communicate with humans, researchers said in their study published today (March 31) in the journal Proceedings of the National Academy of Sciences. 3月31日发表在美国国家科学院院刊上的报告显示，对情感投射的面部表情进行这样的词汇扩充，有助于人脑和社会交流的研究工作、以及与人类交流的计算机系统的设计工作。 Weve gone beyond facial expressions for simple emotions like happy or sad. We found a strong consistency in how people move their facial muscles to express 21 categories of emotions, said study researcher Aleix Martinez, a cognitive scientist and associate professor of electrical and computer engineering at The Ohio State University. That tells us that these 21 emotions are expressed in the same way by n
