Sensing emotion in humans by using a response in facial skin blood flow

我们认为脸和面部颜色与各种情绪有关，因为使用脸的语言表达很多。然后我们测试了面部皮肤血液流动对情绪有特定反应的假设。研究对象观看了唤起快乐、悲伤、恐惧、惊讶和恐惧的视频，然后我们测量了面部皮肤的血流量。额头、鼻子、脸颊和嘴唇的皮肤血流无特异性反应。研究结果可能表明，目前还很难从面部皮肤血流反应来判断一个人的情绪。如果可以的话，应该有必要使用更强的刺激来唤起情绪的变化。

We supposed that face and facial color are related to various emotions, since there are many expressions of language using face. Then we tested the hypothesis that facial skin blood flow shows specific response to emotion. Subjects watched videos evoking happiness, sadness, fear, astonishing and fear, then we measured facial skin blood flow. No specific response was obtained in skin blood flow in forehead, nose, cheek and lips. The results may suggested a difficulty judging one's emotion from facial skin blood flow responses as yet. It should be necessary to use stronger stimulus evoking a change in emotion, if we can.
