In recent years there has been an enormous increase of neuroscience research using the facial expressions of emotion. This has led to a need for ethnically specific facial expressions data, due to differences of facial emotion processing among different ethnicities.
FIFTY PROFESSIONAL ACTORS WERE ASKED TO POSE WITH EACH OF THE FOLLOWING FACIAL EXPRESSIONS IN TURN: happiness, sadness, fear, anger, disgust, surprise, and neutral. A total of 283 facial pictures of 40 actors were selected to be included in the validation study. Facial expression emotion identification was performed in a validation study by 104 healthy raters who provided emotion labeling, valence ratings, and arousal ratings.
A total of 259 images of 37 actors were selected for inclusion in the Extended ChaeLee Korean Facial Expressions of Emotions tool, based on the analysis of results. In these images, the actors' mean age was 38±11.1 years (range 26-60 years), with 16 (43.2%) males and 21 (56.8%) females. The consistency varied by emotion type, showing the highest for happiness (95.5%) and the lowest for fear (49.0%). The mean scores for the valence ratings ranged from 4.0 (happiness) to 1.9 (sadness, anger, and disgust). The mean scores for the arousal ratings ranged from 3.7 (anger and fear) to 2.5 (neutral).
We obtained facial expressions from individuals of Korean ethnicity and performed a study to validate them. Our results provide a tool for the affective neurosciences which could be used for the investigation of mechanisms of emotion processing in healthy individuals as well as in patients with various psychiatric disorders.
近年来，神经科学领域使用情绪面部表情的研究呈指数级增长。这导致了对特定种族面部表情数据的需求，因为不同种族之间的面部情绪处理存在差异。
要求 50 名专业演员依次摆出以下面部表情：高兴、悲伤、恐惧、愤怒、厌恶、惊讶和中性。从 40 名演员中挑选了总共 283 张面部表情图片，用于验证研究。在验证研究中，由 104 名健康评分者进行面部表情情绪识别，他们提供情绪标签、效价评分和唤醒评分。
基于结果分析，共选择了 37 名演员的 259 张图像纳入扩展 ChaeLee 韩国情绪面部表情工具，其中演员的平均年龄为 38±11.1 岁（范围 26-60 岁），男性 16 名（43.2%），女性 21 名（56.8%）。一致性因情绪类型而异，高兴的一致性最高（95.5%），恐惧的一致性最低（49.0%）。效价评分的平均值范围从 4.0（高兴）到 1.9（悲伤、愤怒和厌恶）。唤醒评分的平均值范围从 3.7（愤怒和恐惧）到 2.5（中性）。
我们从韩国个体获得面部表情，并进行了一项验证研究。我们的研究结果为情感神经科学提供了一种工具，可用于研究健康个体以及各种精神障碍患者的情绪处理机制。
