Effects of emotional word valence on ERPs. (A) The upper panel depicts the grand mean ERP waveforms from GFP, central (Cz), and parietal (P3 and P4) electrodes, elicited by emotionally positive, negative, and neutral words. The word was presented at 0 ms. (B) The lower panel shows the scalp distributions (standard amplitude subtraction) of the differences between positive and neutral words and between negative and neutral words and, further, the distribution of ERPs to neutral words within the 400–700-ms interval after the word.
