EEG ASYMMETRY AND SOCIAL BEHAVIOR IN 4 YEAR OLD CHILDREN

最近的数据表明，同龄人的互动是 发展正常的社会关系和社交技能。超过了 在过去的几年里，我们的研究主要集中在 幼儿行为维度与学龄前儿童社会行为的关系 了解脑电不对称性的中介作用。我们还有 在普通人群中研究了发展的连续性和 与行为抑制和社交相关的不连续性 戒烟。我们已经报道过，社交退缩是一种行为 儿童早期社交焦虑和社交退缩的标记物 孩子们在与孩子的互动中缺乏自信和能力 同伴们。在过去的五年里，我们还执行了一些 研究表明，年轻人表现出的情感行为 在新的社会环境中，儿童在一定程度上与特定的 额部脑电不对称的模式。而且，我们已经记录了具体的 婴儿的气质模式与孤僻和压抑有关 在学龄前阶段的行为。具体地说，我们发现 额部脑电不对称模式的个体差异是 与情感反应的效价和儿童的 倾向于以亲社会或孤僻的方式回应同龄人。这个 本申请中提出的研究旨在扩展我们的发现 幼儿行为维度与学龄前儿童关系的研究 对脑电中介作用的理解与社会行为 不对称。 目前的拨款将集中在两个独立的儿童样本上，这些儿童 在四个月大的时候被选为特定的行为 被认为与行为抑制有关的特征。 在两个队列(N=72)和(N=120)中的受试者分别在9岁、14岁、 和24个月大的婴儿。在每个年龄段，行为反应的测量 新奇的事件被记录下来。在每个年龄段，脑电活动(EEG) 是从每个受试者身上记录下来的。我们建议在以下情况下看到这两个队列 孩子们只有四岁。到那时，每个孩子都会被看到 两次。一次和另外三个人在同性四重奏的演奏环节中，还有一次 分别在何时记录脑电。基于我们之前的工作 四岁时的未经挑选的儿童样本，我们认为婴儿 气质和额部脑电不对称性预测社交退缩和 四岁时的社交能力。

Recent data suggest that peer interaction is an important force in the development of normal social relationships and social skills. Over the past number of years our research has focussed on the relations between dimensions of infant behavior and preschool social behavior with an understanding of the mediating role of EEG asymmetry. We have also studied, within the general population, the developmental continuities and dis-continuities associated with behavioral inhibition and social withdrawal. We have reported that social withdrawal is a behavioral 'marker' of social anxiety in early childhood and that socially withdrawn children are less confident and competent in their interactions with peers. Over the past five years we have also performed a number of studies which suggest that the affective behavior displayed by young children in novel social situations is, in part, associated with specific patterns of frontal EEG asymmetry. And, we have documented that specific patterns of infant temperament are associated with withdrawn and inhibited behavior during the preschool period. Specifically, we have found that individual differences in the pattern of frontal EEG asymmetry are associated with the valence of affective response and the child's disposition to respond in a pro-social or withdrawn manner to peers. The research proposed in this application is designed to extend our findings on the relations between dimensions of infant behavior and preschool social behavior with an under-standing of the mediating role of EEG asymmetry. The current grant will focus on two independent samples of children who were each selected at four months of age for specific behavioral characteristics thought to be associated with behavioral inhibition. Subjects in two cohorts (N=72) and (N=120) have been seen at ages 9, 14, and 24 months of age. At each age, measures of behavioral response to novel events were recorded. At each age, brain electrical activity (EEG) was recorded from each subject. We propose to see these two cohorts when children are four years of age. At that time each child will be seen twice. Once with three others in a same sex quartet play session and once individually when EEG will be recorded. Based upon our previous work with an unselected sample of children at age four, we believe that infant temperament and frontal EEG asymmetry will predict social withdrawal and social competence at four years of age.
