中国人微渐变情绪面孔库的建立及分析评估

The Establishment,Analysis and Evaluation of Chinese Micro-morphing Facial Emotion System

建立一套基于中国人相同面孔的同一类型情绪的愉悦度渐变序列的表情图组系统,为中国人情绪障碍研究提供一套本土化的情绪面孔微渐变的标准刺激材料。方法:要求20名被试表演7种基本情绪(开心、悲伤、厌恶、恐惧、愤怒、惊奇、平静),且每种基本情绪要表现出高、中、低3个强度等级,拍摄每个被试每种情绪不同强度的面部表情图片。另选84名评定者对这些图片进行情绪类型的判断和唤醒度、愉悦度、优势度评分,然后将同一面孔的同类情绪图片分在同一组内,再按愉悦度高低排序。结果:获得相同面孔的不同情绪类型图组共78组,每组包含同一个人从平静表情到不同愉悦度某类情绪的序列表情图片,其中开心表情20组、愤怒表情15组、悲伤表情18组、厌恶表情10组、惊奇表情14组、恐惧表情1组,共计图片603张,每张图片都有对应的认同率及情绪唤醒度、愉悦度、优势度评分。结论:中国人情绪面孔微渐变图组系统为情绪认知研究提供了更灵敏的标准化的表情刺激材料。

To develop a localized set of standard stimulus material of micro-morphing facial emotion system which shows the valence sequence of a particular emotional type,and each sequence is based on the same face.20 participants were asked to perform 7 types of basic emotion(happiness,anger,sadness,disgust,surprise,fear,and calm),and each type of basic emotion includes high,moderate and low intensity.Another 84 participants were recruited to judge the emotion type and rate their arousal,valence,dominance.Classify the same emotional pictures of the same face into the same group,and then sort in order of valence.A total of 78 groups of different emotion types of the same face were obtained,and each group contained the same person’s sequential expression pictures ranging from calm to certain emotion with different valence,which included 20 happy groups,15 angry groups,18 sad groups,10 disgust groups,14 surprise groups and 1 fear group.Each of these 603 picture has its corresponding arousal,valence,dominance and identity rate.The Chinese micro-morphing facial emotion system developed in this study has good reliability and validity and can be used as a more sensitive set of standardized emotional stimuli.
