Measures of EEG spectral power, lateral asymmetry in the frontal and parietal areas, and social behavior with an examiner were analyzed on 166 children, 10 to 12 years old, who were participating in a longitudinal study of the temperamental contributions to social behavior. Loss of 8- to 13-Hz power (alpha band) on the right, compared with the left, frontal area (right frontal active) was most prevalent among children who were classified as high reactive at 4 months and were highly fearful at 14 and 21 months. Second, greater frontal power in the 14- to 30-Hz band (beta) at rest was correlated with the tendency to be right frontal active. Finally, spontaneous talkativeness with an unfamiliar examiner was associated with right frontal activation and high alpha power for boys, but with right frontal activation and high beta power for girls. Right frontal activation is most characteristic of children who begin life with a temperamental bias favoring high reactivity and who develop a fearful reaction to unfamiliar events in the second year of life.
对166名10至12岁参与气质对社会行为影响纵向研究的儿童，分析了脑电图频谱功率、额叶和顶叶区域的横向不对称性以及与检查者的社会行为。与左侧额叶区域相比，右侧8至13赫兹功率（阿尔法波段）丧失（右侧额叶活跃）在4个月时被归类为高反应性且在14个月和21个月时高度恐惧的儿童中最为普遍。其次，静息状态下14至30赫兹波段（贝塔波段）更大的额叶功率与右侧额叶活跃的倾向相关。最后，与陌生检查者自发健谈对男孩而言与右侧额叶激活和高阿尔法功率相关，但对女孩而言与右侧额叶激活和高贝塔功率相关。右侧额叶激活是那些从生命开始就具有倾向于高反应性的气质偏差且在生命第二年对陌生事件产生恐惧反应的儿童的最典型特征。
