Fig 2.
The ERP grand-average waveforms and topographic maps of N2 and early frontal LPP.
(A) Fz, FCz and Cz were selected for N2 (shaded 210–280 ms time window) and LPP (shaded 380–480 ms) waveforms to compare among “attractive”, “unattractive” and “attractive minus unattractive” face conditions. (B) The bars for attractive and unattractive faces of the N2, early frontal LPP, N2 difference, LPP difference topographic maps range from -1.5μV to 6.5μV, -1μV to 6.5μV, -0.7μV to 0.7μV and -0.5μV to 1.5μV respectively.

Fig 3.
The ERP grand-average waveforms and topographic map of FRN.
(A) Fz, FCz, and Cz were selected for FRN (shaded 260–320 ms) waveforms to compare fair and unfair offers in the two face conditions. (B) The bar for four offer conditions of FRN topographic map ranges from -5.5μV to 6μV.
Fig 4.
The ERP grand-average waveforms and topographic map of P300.
(A) CPz and Pz were selected for P300 (shaded 460–560 ms) waveforms to compare fair and unfair offers in the two face conditions. (B) The bar for four offer conditions of P300 topographic map ranges from -4.5μV to 6.5μV.
