N200 condition effect. N200 waveforms were averaged from the 20 subjects, and we pooled the data from F1, Fz, F2, FC1, FCz, FC2, C1, Cz, and C2 electrodes. (A) Grand-averaged ERP waveforms in the frontal regions with three electrodes (Fz, FCz, and Cz); (B) Line chart of the mean and standard error of the N200 amplitude across the 2 (prominent logo vs no logo) by 2 (genuine brand vs counterfeit brand) conditions. (C) Topographic maps of four conditions for N200 amplitude. The N200 comparison of the four conditions (genuine brand with a prominent logo, genuine brand without a logo, counterfeit brand with a prominent logo, and counterfeit brand without a logo).
