The pattern of frontal activation as measured by the ongoing electroencephalogram (EEG) may be a marker for individual differences in infant and adult disposition to respond with either positive or negative affect. We studied 48 4-year-old children who were first observed in same-sex quartets during free-play sessions, while making speeches, and during a ticket-sorting task. Social and interactive behaviors were coded from these sessions. Each child was subsequently seen 2 weeks later when EEG was recorded while the child attended to a visual stimulus. The pattern of EEG activation computed from the session was significantly related to the child's behavior in the quartet session. Children who displayed social competence (high degree of social initiations and positive affect) exhibited greater relative left frontal activation, while children who displayed social withdrawal (isolated, onlooking, and unoccupied behavior) during the play session exhibited greater relative right frontal activation. Differences among children in frontal asymmetry were a function of power in the left frontal region. These EEG/behavior findings suggest that resting frontal asymmetry may be a marker for certain temperamental dispositions.
通过持续脑电图（EEG）测量的额叶激活模式可能是婴儿和成人在以积极或消极情绪做出反应的性情方面个体差异的一个标志。我们研究了48名4岁儿童，他们首先在自由玩耍环节、演讲时以及在票据分类任务中以同性四人小组的形式被观察。从这些环节中对社交和互动行为进行编码。两周后，每个孩子在观看视觉刺激时记录脑电图时再次接受观察。从该环节计算出的脑电图激活模式与孩子在四人小组环节中的行为显著相关。表现出社交能力（高度的社交发起和积极情绪）的孩子表现出相对更强的左额叶激活，而在玩耍环节表现出社交退缩（孤立、旁观和无所事事的行为）的孩子表现出相对更强的右额叶激活。儿童额叶不对称的差异是左额叶区域功率的一个函数。这些脑电图/行为研究结果表明，静息额叶不对称可能是某些气质性情的一个标志。
