微表情是一种短暂的、微弱的、无意识的面部微表情，持续时间往往在0.5s内，能够揭示人类试图隐藏的真实情绪。微表情识别的研究旨在让机器有足够的智能，能够从人脸视频序列中识别人类的真实情绪。然而由于微表情持续时间短、面部肌肉运动强度低，对其进行准确的表征与识别是一项极具挑战性的任务。为了促进心理学领域和计算机视觉领域针对微表情的进一步研究，由拉斯维加斯手机娱乐网站 （CSIG）和中国科学院心理研究所举办、CSIG机器视觉专业委员会、CSIG情感计算与理解专业委员会和中科院青促会心理所小组联合承办，中国科学院心理研究所的王甦菁博士组织一系列云上微表情的学术活动。

第五十五期云上微表情将于2024年08月30日晚上7点进行，由中国科学院心理研究所王甦菁老师团队的李婧婷博士主持。此次讲座邀请到来自辽宁大学心理测试与行为分析实验室的周星辰副教授作主题为“复杂欺骗策略的面部表情特点”的学术报告，欢迎大家关注！

报告题目：An Honest Joker reveals stereotypical beliefs about the face of deception

中文题目：复杂欺骗策略的面部表情特点

报告摘要：Research on deception detection has mainly focused on Simple Deception, in which false information is presented as true. Relatively few studies have examined Sophisticated Deception, in which true information is presented as false. Because Sophisticated Deception incentivizes the appearance of dishonesty, it provides a window onto stereotypical beliefs about cues to deception. Here, we adapted the popular Joker Game to elicit spontaneous facial expressions under Simple Deception, Sophisticated Deception, and Plain Truth conditions, comparing facial behaviors in static, dynamic nonspeaking, and dynamic speaking presentations. Facial behaviors were analysed via machine learning using the Facial Action Coding System. Facial activations were more intense and longer lasting in the Sophisticated Deception condition than in the Simple Deception and Plain Truth conditions. More facial action units intensified in the static condition than in the dynamic speaking condition. Simple Deception involved leaked facial behaviors of which deceivers were unaware. In contrast, Sophisticated Deception involved deliberately leaked facial cues, including stereotypical cues to lying (e.g., gaze aversion). These stereotypes were inaccurate in the sense that they diverged from cues in the Simple Deception condition—the actual appearance of deception in this task. Our findings show that different modes of deception can be distinguished via facial action analysis. They also show that stereotypical beliefs concerning cues to deception can inform behavior. To facilitate future research on these topics, the multimodal stimuli developed in this study are available free for scientific use.
