Grand averages according to the making-choices stages. The first row contains grand averages (N2 on electrode Fz and P3 on electrode Pz) for trusting decision, separated by happy, angry, and neutral faces of female or male trustees. The second row contains grand averages (N2 on electrode Fz and P3 on electrode Pz) for distrusting decision, separated by happy, angry, and neutral faces of female or male trustees. Vertical lines indicate the time windows that were quantified for statistical analyses. The topographic maps are also based on these time windows. *: p < 0.05.
