基于微表情的欺骗检测研究

欺骗在生活中经常出现，为了不被欺骗，寻求欺骗的线索是人们孜孜以求的目标，尤其是当欺骗会带来严重后果的时候（如反恐实践）。在众多欺骗线索中，微表情被认为是一种有效的线索。然而，当前却对微表情在欺骗检测中进行应用存在争议，其可行性、有效性证据知之甚少。本项目拟通过实证研究阐明欺骗与微表情的关系、微表情识别与欺骗检测之间的关系。主要回答微表情在欺骗检测中进行应用亟待解决的三个问题：欺骗是否总是伴随着微表情？微表情识别能力和欺骗检测能力的相关程度有多高？欺骗与微表情以及微表情识别与欺骗检测之间联系背后的认知神经机制是什么？这些科学问题的解决，将进一步深化对微表情这一前人研究较少的心理现象的认识，并为微表情应用到欺骗检测奠定坚实的理论基础。

Deception and lying are popular in daily life. To prevent cheating, people invested many efforts on detecting the cues of deception and lying, especially while deception can cause serious consequences (e.g., anti-terrorism). Among the cues to deception, microexpression is regarded as a valid one. However, little is known about the feasibility and validity of the application of microexpression in the field of deception detection. The current research proposal aims to elucidate the relation between deception and microexpression, and the relation between microexpression recognition and deception detection. The proposed studies will solve three most urgent problems while applying microexpression to detect deception. First, is deception always associated with microexpression? Secondly, how strong is the correlation between microexpression recognition and deception detection? What is the cognitive and neural mechanisms underlying the relation between deception and microexpression, and the relation between microexpression recognition and deception detection? The studies in the current proposal will deepen our understanding of microexpression, and will establish the foundation of applying microexpression to detect deception.
