In the recent review by Waller et al. (2020) the authors discuss how the Facial Action Coding System (FACS) can be used to study the evolution of facial behaviors. This is a timely and thought-provoking review which highlights the numerous ways in which FACS could be used to compare the mechanisms responsible for the production of facial behaviors across species. We propose that FACS could also be used to study the recognition of facial behaviors in nonhuman subjects where one of the key challenges is finding suitable stimuli that convey different emotions. By using FACS-rated images in awake neuroimaging experiments, researchers could accurately identify the brain mechanisms responsible for recognizing expressions across mammalian species. This approach would reveal neural homologs and deepen our understanding of how nonverbal social communication has evolved.
在 Waller 等人（2020 年）的近期综述中，作者讨论了面部动作编码系统 (FACS) 如何用于研究面部行为的进化。这是一篇及时且发人深省的综述，强调了 FACS 可以用于比较跨物种产生面部行为的机制的许多方法。我们提出，FACS 也可以用于研究非人类受试者对面部行为的识别，其中一个关键挑战是找到传达不同情绪的合适刺激。通过在清醒神经影像学实验中使用 FACS 评分图像，研究人员可以准确识别负责识别哺乳动物物种表情的大脑机制。这种方法将揭示神经同源物，并加深我们对非言语社会交流如何进化的理解。
