Electrophysiological results. On the Y-axis the amplitude (microvolts); on the X-axis the time (milliseconds). All CNV depicted in the figure represent the average of the nine electrodes considered (i.e. F3, FZ, F4, C3, CZ, C4, P3, PZ, P4) and dotted rectangular area represent the early (between 1000 and 2000 ms) and late (between 3000 and 4000 ms) CNV. A Direct comparison of the CNV after red and green cues in the no-social group. B Direct comparison of the CNV after red and green cues in the social group. *P < 0.05; **P < 0.01
