项目摘要

The purpose of the research is whether there are any cultural differences in facial recognition among Asian people. Asian people are regarded as non-dialectic culture in which mixed facial expressions of positive and negative feelings are commonly used, while the European and American people are in dialectic culture where only distinct emotional expressions are used in personal communicationThis research was composed of four experiments. In the first experiment, 24 cards of facial expressions of an average Japanese man are used for stimuli, which were composed of 2 sets of 6 distinct emotional expressions and 2 sets of mixed facial expressions. Five Japanese students and three Chinese students were asked to sort the face cards into 6 emotional status; anger, sorrow, joy and happiness, disgust, dislike and anxiety, and surprise. The Japanese students answered 100 % correct on happy expression, and almost perfectly sorted cards into correct facial expressions. On the other hand, Chinese … More students were able to sorted cards correctly only happy and angry faces, but not others facial expression, especially mixed cards.In the second experiment, 139 Japanese students were asked to write down what kind of feeling 26 facial expressions were indicated when they were presented faces on the projector screen. On the screen, blank were shown for 2 seconds and facial stimuli were presented for 5 seconds. They were told to look at the face stimulus, and write down the number which indicated the on a sheet of paper. The students answered on smile faces with 98 % correct, and on other faces with more than 60 % correct.In the third experiment, using the same stimuli, students living in Brazil were asked to participate in the same experiment as the second experiment. They answered 66 % correct on happy and surprise, but less than 15 % correct on other expressions.In the fourth experiment, brain blood circulations of 3 Japanese students and 3 Chinese students were measured using fNIRS. As the results, no big blood circulation was occurred among right temporal lobe where worked for facial recognition among Japanese students, but distinctive increase of blood circulation was recognized among Chinese students.In conclusion, facial expression of the mixed of positive and negative feelings among the Japanese were hard to recognize for Chinese people even though they were recognized in the same Non-dialectic culture, moreover for the Brazilianwhere positive and negative facial expressions were distinct in personal communication. So, in order to have better communication, Japanese people need to make their face clearly to express their feelings. Otherwise, foreigners are very likely not to understand how they feel at all.

这项研究的目的是研究亚洲人在面部识别方面是否存在文化差异。亚洲人被认为是非辩证文化，通常使用积极和消极情绪的混合面部表情，而欧洲人和美国人则处于辩证文化中，在个人交流中只使用不同的情绪表情。在第一个实验中，使用24张日本普通男性的面部表情卡作为刺激，由2组6种不同的情绪表情和2组混合的面部表情组成。5名日本学生和3名中国学生被要求将面部卡片分成6种情绪状态；愤怒，悲伤，喜悦和幸福，厌恶，不喜欢和焦虑，以及惊讶。日本学生对快乐表情的回答100%正确，并且几乎完美地将卡片分类为正确的面部表情。更多的学生能够正确地分辨出快乐和愤怒的面孔，而不能正确地分辨出其他的面部表情，尤其是混合的面孔。在第二个实验中，139名日本学生被要求写下当他们在投影仪屏幕上看到面孔时所表现出的26种面部表情。在屏幕上，空白显示2秒，面部刺激显示5秒。他们被要求观察面部刺激，并在一张纸上写下表示刺激的数字。学生们回答微笑面孔的正确率为98%，回答其他面孔的正确率超过60%。在第三个实验中，使用相同的刺激，居住在巴西的学生被要求参加与第二个实验相同的实验。他们对“高兴”和“惊讶”的回答正确率为66%，但对其他表情的回答正确率不到15%。在第四项实验中，使用近红外光谱测量了3名日本学生和3名中国学生的脑血液循环。结果显示，日本学生的右颞叶的血液循环并不大，而中国学生的血液循环明显增加。综上所述，日本人的积极情绪和消极情绪混合的面部表情即使在同一种非辩证法文化中也很难被中国人识别出来，而巴西人的积极情绪和消极情绪在个人交流中是截然不同的。所以，为了更好的交流，日本人需要用清晰的表情来表达自己的感受。否则，外国人很可能根本无法理解他们的感受。少
