本文评估了大脑前部区域的静息脑电(EEG)不对称性是否可以预测对情绪激发剂的情绪反应。研究人员记录了32名成年女性的基线脑电，然后让学生观看预先选择好的电影片段，以引发积极或消极的情绪。额叶静息阿尔法功率不对称显著预测了对CLIPS反应的自我报告的整体负面情绪，并预测了整体正面情绪和负面情绪之间的差异。对离散情绪的分析表明，额叶不对称与对电影的恐惧反应之间存在很强的联系。在测量基线脑电时，影响与SS情绪分级无关。静止性前部不对称可能是个体情感性反应倾向的状态独立指标。
This article assessed whether resting electroencephalographic (EEG) asymmetry in anterior regions of the brain can predict affective responses to emotion elicitors. Baseline EEG was recorded from 32 female adults, after which Ss viewed film clips preselected to elicit positive or negative affect. Resting alpha power asymmetry in the frontal region significantly predicted self-reported global negative affect in response to clips and predicted the difference between global positive and negative affect. Analyses of discrete emotions revealed a strong relation between frontal asymmetry and fear responses to films. Effects were independent of Ss mood ratings at the time at which baseline EEG was measured. Resting anterior asymmetry may be a state-independent index of the individual's predisposition to respond affectively.
