Objective: To study the electrophysiology traits on children temperament. Methods:Three groups of children,with easy temperament (E group),difficult temperament(D group) and slow tepmerament(S group) respectively,were selected and their results of EEG and BEAM were analysed.Results::1 EEG visual analysis showed no significant differences among three groups.2.In slow wave (δ,θ) band three groups had no significant difference in every brain region; In α1 band, the absolute power of D group were lower than that of the other two groups at forehead , central ,parietal and occipital regions in left hemisphere; In α2 band , the absolute power of E group were higher than that of the other two groups in almost every brain regions; In β band ,the absolute power of D group were lower than that of the other two groups at forehead , central ,parietal and occipital regions. Conclusion:Children with different temperament showed different EEG and BEAM features.
