The review highlights the potential of using FACS to compare mechanisms responsible for facial behaviors across species and to study facial behavior recognition in nonhuman subjects. By utilizing FACS-rated images in awake neuroimaging experiments, researchers can identify brain mechanisms responsible for recognizing expressions across mammalian species, which deepens our understanding of nonverbal social communication evolution.
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.
