While physiological reactivity to and appraisal of emotional faces is often studied \nusing static images, this study aimed to enhance ecological validity by using live face models. \nParticipants (N = 25) viewed a face model through a liquid crystal screen (LCS) that revealed \nsad, angry, or neutral expressions. Skin conductance response (SCR) and facial \nelectromyography (EMG) were recorded, along with behavioral measures of emotion \nrecognition and perceived intensity. \nHigher SCR to sad and neutral faces was associated with better recognition accuracy of sad \nexpressions. A trend also suggested that stronger SCR was linked to greater perceived intensity \nof sad faces. EMG responses varied by emotion: zygomatic activity was highest during sad and \nneutral faces, while corrugator activity was lowest during angry faces. Notably, greater EMG \nactivity to neutral expressions \u2014 both zygomatic and corrugator \u2014 was linked to a worse \nrecognition accuracy of neutral faces. \nNo significant differences were found between participants with higher versus lower anxiety \nand depression symptoms in either physiological responses or behavioral outcomes. \nThese findings suggest that individual physiological reactivity, rather than symptom severity, \nmay support or interfere with accurate emotional face recognition and appraisal \u2014 particularly \nfor sad and neutral expressions.
