Three studies re-tested the relationship between emotional mimicry and emotional contagion from the perspective of epistemic motivation. In experiment 1, participants' electromyography(EMG), event-related potentials, as well as self-reported emotional experience were recorded while watching others' emotion. We found enhanced EMG activity of zygomaticus major (ZM) to happy faces and increased EMG activity of corrugator supercillii (CS) to angry faces. More importantly, amplitude of late positive potential (LPP) was larger when ZM activity to happy faces was high, and when CS activity to angry faces was high, which confirmed the role of emotional mimicry in emotional contagion. Then, epistemic motivation was measured in experiment 2 and manipulated as power in experiment 3, which both found that participants with lower epistemic motivation were more inclined to converge others' emotion via emotional mimicry, with larger increase in amplitude of LPP and self-reported emotional experience under different degree of emotional mimicry.
