中国面部表情视频系统的初步建立

目的：建立本土化的中国面部表情视频系统（ehinese facial expression video system，CFEVS）以增加情绪研究的取材范围。方法：录制强度分为三等级的喜悦、悲伤、惊奇、恐惧、愤怒、厌恶及中性（无表情及咀嚼动作两种）等面部表情视频片段，经两轮粗选后，请50名中国大学生对剩余视频片段的表情类型、愉悦度、唤醒度及表演者的长相进行自我报告式评定。将表情类型、愉悦度、唤醒度一致性高且表情类型与愉悦度相一致的片段纳入CFEVS，做分布分析，同时分析评测者性别、表演者长相对愉悦度、唤醒度分值的影响。结果：纳入CFEVS的喜悦表情男18女43共61个，悲伤表情男23女28共51个，无表情中性男13女17共31个，咀嚼中性男7女17共24个。散点图显示CFEVS在愉悦度及唤醒度上分布较为广泛。方差分析表明评测者性别及表演者长相对视频片段的愉悦度、唤醒度的影响与其表情类型有关。结论：本研究初步建立了一个拥有喜悦、悲伤及中性表情的CFEVS，并发现评测者的性别及表演者的长相可影响实验结果。

The Primary Development of Chinese Facial Expression Video System

Objective:To develop the Chinese Facial Expression Video System (CFEVS) for future emotion research.Methods: Different facial expression video slices of happiness, sadness, surprising, fear, anger, disgust at three levels of intensity and neutral (including non-emotional and chewing) were recorded. After twice preliminary screening, 50 Chinese university students were asked to rate the category, valence, arousal of the residual video slices and the appearance of actors and actresses by self-report. Those video slices with high consistency of category, valence, arousal and with concordance of category and valence were collected to make up of CFEVS. The effects of raters' gender and performers' appearance on valence and arousal were analyzed. Results: 61 happy faces (18 male' and 43 female'), 51 sad faces (23 male' and 28 female'), 30 non-emotional neutral (13 male' and 17 female') and 24 chewing neutral (7 male' and 17 female') were recruited in CFEVS. Scatter plot showed that the score distribution on the dimension of valence and arousal was wide in CFEVS and the results of ANOVA indicated the effects of raters' gender and performers' appearance on the scores of valence and arousal were correlated with expressional category. Conclusion: The Chinese Facial Expression Video System has been preliminarily developed though need to be refined, and the gender of raters and the appearance of performers are perhaps important influencing factors to the results of emotional research.
