Two-tailed Pearson correlation analyses between the mean amplitude of LPP and RT were performed at the group level in order to explore if there were functional connections between one's brain activity and behavioral performance. It showed significant negative correlation between LPP amplitude and RT in NP (r = −0.381, p = 0.041), but no significant correlations between them in ZP (r = −0.102, p = 0.600), and LP (r = −0.320, p = 0.091).
