面部动作编码系统（FACS）是用于通过描述面部肌肉的运动来识别和标记面部表情的广泛使用的协议。FACS用于客观地测量面部表情的频率和强度，而不对这些肌肉运动赋予任何情感意义。相反，流式细胞仪将面部表情分解为最小的可辨别的运动，称为动作单元。每一个动作单元都能在面部外观上产生明显的变化，比如眉毛提升或鼻子皱纹。当观看静止图像或视频时，FACS编码器可以识别存在于面部上的动作单元。心理学研究已经使用FACS来检查各种研究问题，包括社会情感发展，神经精神障碍和欺骗。在本报告中，我们提供了一个概述的FACS和行动单位，其作为一种措施的可靠性，以及它是如何被应用于心理学研究的一些关键领域。
The Facial Action Coding System (FACS) is a widely used protocol for recognizing and labelling facial expression by describing the movement of muscles of the face. FACS is used to objectively measure the frequency and intensity of facial expressions without assigning any emotional meaning to those muscle movements. Instead FACS breaks down facial expressions into their smallest discriminable movements called Action Units. Each Action Unit creates a distinct change in facial appearance, such as an eyebrow lift or nose wrinkle. FACS coders can identify the Action Units which are present on the face when viewing still images or videos. Psychological research has used FACS to examine a variety of research questions including social-emotional development, neuropsychiatric disorders, and deception. In the course of this report we provide an overview of FACS and the Action Units, its reliability as a measure, and how it has been applied in some key areas of psychological research.
