This systematic review aimed at exploring gender differences in emotion regulation through electrophysiological measures, focusing specifically on the late positive potential (LPP) during tasks involving cognitive reappraisal and expressive suppression. A thorough search process identified six experimental studies that met the inclusion criteria. These studies utilized varying electrophysiological measures where the most prominent one was the LPP, providing a consistent focus for this review. The results indicate that males generally exhibit lower LPP amplitudes than females in both reappraisal and suppression conditions. However, significant methodological variations across the studies, particularly in electrode placement, time windows, and experimental designs, hinder the ability to draw definitive conclusions about the underlying causes of these differences. Such discrepancies emphasize the need for more standardized research approaches. Future research should strive to minimize these methodological differences and develop a more unified approach to investigating the electrophysiological correlates of gender differences in emotion regulation.
