ERP results of study 1. A) The ERP grand-average waveforms of five conditions at the FCz electrode; B) the N400 amplitudes (mean ± SE, in μV) for the friend higher, friend lower, and no conflict conditions, as well as the topographical maps for the different wave between conflict and no conflict conditions; (C) the late positive potential (LPP) amplitudes (mean ± SE, in μV) for the desirable, undesirable, and no conflict conditions, as well as the topographical maps for the different wave between desirable and undesirable conditions; D) correlation between strategic mindset the mean N400 amplitude of conflict condition. Since the N400 represents a negative fluctuation, the positive correlation suggests that participants who reported a higher level of strategic mindset tended to exhibit a smaller N400 amplitude; E) correlation between strategic mindset the mean LPP amplitude of desirable condition; F) correlation between strategic mindset the mean LPP amplitude of undesirable condition.
