摘　　要：目的 采用静息脑电技术研究正常成年人额叶alpha波偏侧化是否受到年龄因素的影响,同时进一步验证静息脑电alpha波偏侧化作为情绪调节能力指标的稳定性.方法 正常青年人（18～ 25岁）30人,正常中年人（40 ～ 50岁）30人,首先采集脑电,对脑电数据进行离线分析,将最终数据转化成自然对数,然后用SPSS 17.0软件处理,对两组人群进行分析.结果 正常成年人额叶静息脑电Alpha波存在偏侧化（F =6.865,P＜0.05）.青年组与中年组额叶静息脑电在F3/F4点（t=-0.346,P＞0.05）；F7/F8点（t=-0.121,P＞0.05）；FP1/FP2点的偏侧化程度均不存在差异（t=-0.192,P＞0.05）.结论 正常成年人额叶静息脑电偏侧化不受年龄因素影响,额叶静息脑电Alpha波偏侧化作为情绪调节能力的指标在年龄差异上具有一定的稳定性.Objective Using the resting EEG to explore weather the age difference will affect the alpha frontal asymmetry, further validate resting EEG alpha asymmetry stability as indicator of emotion regulation ability. Methods A total of 30 normal young people （18 to 25 years old）and 30 normal middle-aged（40 to 50 years old） , first collected EEG, analyzing the EEG data on off-line, the final data into natural logarithms, then using the SSPS 17.0 software processing, finally the two groups were analyzed. Results Normal adult frontal resting EEG alpha existed asymmetry（ F = 6. 865 ,P 〈 0.05 ）. There was no difference in frontal asymmetry between youth group and the middle-age group. Conclusion Normal adult frontal resting EEG asymmetry is not affected by age factor. There are a certain sta- bility on frontal resting EEG alpha asymmetry as a emotional ability to adjust the indicators in age difference. [,
