A visual evoked affective experiment is designed and carried out to collect the electroencephalogram(EEG)data labeled with anger and relaxation emotion states. Twenty-one healthy college students(female 9, male 12) are employed to stimulate emotion by different affective pictures. Event-Related Spectral Perturbation(ERSP) is used to discover the pronounced features of anger tendency prediction in the time-frequency domain. ERSP maps exhibit that there is a difference between the female and male group, which is statistically significant within the 150-250 ms and 350-450 ms time range of alpha band. The male group is more susceptible to anger than female group, while the female group is faster in emotional regulation than the male group.These feature values could be used to identify the tendency of angry emotion, which can provide certain reference basis for further research on the predict the tendency of aggressive behavior.展开更多
