在正常发育的10个月大的婴儿中，研究了观察到的和母亲评定的恐惧行为和额叶脑电图（EEG）不对称性的个体差异。EEG记录在休息基线，以及在陌生人的方法，面具介绍，玩具蜘蛛介绍。母亲完成了婴儿行为问卷。对于面具介绍，基线和任务右额叶脑电图不对称性以及母亲的评级预测恐惧行为在面具任务。对于陌生人接近，控制基线不对称后，任务相关的右额叶脑电不对称预测陌生人接近过程中的恐惧行为。在控制基线不对称性后，任务相关的右额叶脑电图不对称性有预测玩具蜘蛛演示期间恐惧的趋势。在控制了基线和任务EEG后，母亲的气质报告仅增加了一个恐惧任务的预测的唯一方差。在多种情况下评估恐惧揭示了婴儿恐惧的特定背景的个体差异。
Individual differences in observed and maternal-rated fear behaviors and frontal electroencephalogram (EEG) asymmetry were examined in normally developing 10-month-old infants. EEG was recorded during resting baseline, as well as during stranger approach, mask presentation, and toy spider presentation. Mothers completed the Infant Behavior Questionnaire. For mask presentation, baseline and task right frontal EEG asymmetry as well as maternal ratings predicted fear behavior during the mask task. For stranger approach, task-related right frontal EEG asymmetry predicted fear behavior during stranger approach after controlling for baseline asymmetry. There was a trend for task-related right frontal EEG asymmetry to predict fear during presentation of a toy spider after controlling for baseline asymmetry. Maternal report of temperament only added unique variance to the prediction of one fear task after controlling for baseline and task EEG. Assessing fear in multiple situations revealed context-specific individual differences in infant fear.
