Event‐Related Potentials to Facial Expressions Are Related to Stimulus‐Level Perceived Arousal and Valence

1 Introduction Facial expressions are a critical source of social information, providing details about others' internal states (Keltner et al. 2019). The neural time course of expression processing has been extensively studied using Event-Related Potentials (ERPs) and is often assumed to relate to expressions' perceived valence and arousal (e.g., Calvo, Marrero, et al. 2013; Calvo and Nummenmaa 2016; Durston and Itier 2021; Han et al. 2021; Schupp, Ohman, et al. 2004).

1 INTRODUCTION Adaptive behavior requires the ability to monitor one's actions. Action monitoring is necessary for detecting mistakes and implementing compensatory behaviors (Botvinick et al., 2001; Rabbitt, 1966). As mistakes can coincide with physical, social, or financial costs, individuals tend to be highly motivated to avoid them.

Mass-univariate analysis of scalp ERPs reveals large effects of gaze fixation location during face processing that only weakly interact with face emotional expression | Scientific Reports

Abstract Decoding others’ facial expressions is critical for social functioning. To clarify the neural correlates of expression perception depending on where we look on the face, three combined gaze-contingent ERP experiments were analyzed using robust mass-univariate statistics. Regardless of task, fixation location impacted face processing from 50 to 350 ms, maximally around 120 ms, reflecting retinotopic mapping around C2 and P1 components.
