Event-related EEG oscillatory responses elicited by dynamic facial expression

摘要

Box plots of the Kruskal–Wallis test for scores of the valence, arousal, and FE recognition. Asterisks (*) stands for significant pairwise comparisons. FE: facial expression, SE: standard error, SD: standard deviation. The maximum possible recognition score was four points for each FE. Valence scores and arousal scores ranged from 1 to 9 (negative to positive and low to high excitation, respectively, see Methods for details)
