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.
