检查婴儿气质的某些特征是否可能与静息额叶激活不对称性的个体差异有关。记录了 13 名 10 个月大婴儿左右额叶和顶叶头皮区域的脑电图。然后在短暂的母亲分离期间观察婴儿的行为。与不哭泣的婴儿相比，那些因母亲分离而哭泣的婴儿在之前的基线期间表现出更大的右额叶激活。额叶激活不对称可能是对压力事件的反应阈值和对特定情绪的脆弱性的个体差异的状态独立标记。
Examined whether certain features of infant temperament might be related to individual differences in the asymmetry of resting frontal activation. EEG was recorded from the left and right frontal and parietal scalp regions of 13 normal 10-month-old infants. Infant behavior was then observed during a brief period of maternal separation. Those infants who cried in response to maternal separation showed greater right frontal activation during the preceding baseline period compared with infants who did not cry. Frontal activation asymmetry may be a state-independent marker for individual differences in threshold of reactivity to stressful events and vulnerability to particular emotions.
