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.
研究了婴儿气质的某些特征是否可能与静息额叶激活的不对称性个体差异有关。记录了13名正常10个月大婴儿左右额叶和顶叶头皮区域的脑电图。然后在母婴短暂分离期间观察婴儿的行为。与未哭泣的婴儿相比,那些因母婴分离而哭泣的婴儿在之前的基线期表现出更大的右侧额叶激活。额叶激活不对称可能是对应激事件反应阈值和对特定情绪易感性个体差异的一种与状态无关的标志物。
