Although numerous studies have investigated emotion regulation, the physiological responses and neural substrates of positive emotion regulation remain unclear. To address this question, we explored the effect of reappraisal on subjective experience, zygomatic electromyography (zEMG) response, and blood oxygen level response, using the same materials across three independent experiments. Behaviorally, up-regulating positive emotion increased the valence, arousal, and zEMG response, whereas down-regulating positive emotion decreased the valence, but not arousal or the zEMG response.
