这项研究评估了前脑不对称性的个体差异是否与情绪基本维度的差异有关。 在每2个实验会话，间隔3周，休息脑电图（EEG）活动记录从女性成年人在8 60秒的基线。 平均α功率不对称性在两个会议中提取中额和前颞部网站。 在两个区域中，与表现出稳定和极端相对右前激活的组相比，表现出稳定和极端相对左前激活的组报告了增加的广义积极影响（PA）和减少的广义消极影响（NA）。 额外的相关性分析显示，前不对称和PA和NA之间的强大的关系，特别是在受试者谁表现出稳定的模式，随着时间的推移脑电图激活。 前部不对称与全身反应性的个体差异无关。
This research assessed whether individual differences in anterior brain asymmetry are linked to differences in basic dimensions of emotion. In each of 2 experimental sessions, separated by 3 weeks, resting electroencephalogram (EEG) activity was recorded from female adults during 8 60-s baselines. Mean alpha power asymmetry across both sessions was extracted in mid-frontal and anterior temporal sites. Across both regions, groups demonstrating stable and extreme relative left anterior activation reported increased generalized positive affect (PA) and decreased generalized negative affect (NA) compared with groups demonstrating stable and extreme relative right anterior activation. Additional correlational analyses revealed robust relations between anterior asymmetry and PA and NA, particularly among subjects who demonstrated stable patterns of EEG activation over time. Anterior asymmetry was unrelated to individual differences in generalized reactivity.
