  结果显示: 分裂型特质的总分(r = .81, p < .01)及其三个维度(r_values > .71, p_values < .01)均有较高的跨时间稳定性;不同频段的脑电功率具有一定程度的稳定性(r = .44, p < .01),且低频波的稳定性高于高频波;分裂型特质的总分和不同维度得分分别与不同频段的额叶脑电不对称性呈负相关。

  第一次测量中,分裂型特质的总分与beta2(r = -.35, p < .05)和 gamma(r = -.38, p < .01)有关联。分维度看,这种关联主要存在于人际性维度和无组织性维度(图1)。三个月后的第二次测量中,分裂型特质的总分则与额叶theta频段(r = -.36, p < .05)和alpha频段(r = -.38, p < .05)的不对称性存在关联。分维度看,这种关联主要存在于认知-知觉性和无组织性维度(图2)。

  此外,研究发现额叶beta2和gamma的不对称性与被试言语流畅度呈负相关(beta2: r = -.31, p < .01; gamma: r = -.34, pBG视讯网 < .05)。
