EEG ASYMMETRY AND SOCIAL BEHAVIOR IN 4 YEAR OLD CHILDREN

最近的数据表明，同伴互动是一个重要的力量， 发展正常的社会关系和社会技能。 来 过去几年，我们的研究集中在 幼儿行为和学龄前社会行为的维度， 了解EEG不对称的中介作用。我们还 在一般人群中，研究了发展的连续性， 与行为抑制和社交相关的中断 戒断 我们已经报道过社交退缩是一种行为上的 幼儿期社交焦虑的“标记”和社交退缩 孩子们在与他人的互动中缺乏自信和能力。 同龄人 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 儿童在新的社会情况下，部分是与特定的， 额叶脑电不对称的模式我们已经记录了 婴儿的气质类型与孤僻和抑制有关 学前阶段的行为。 具体来说，我们发现， 额叶脑电不对称模式的个体差异是 与情感反应的效价和孩子的 倾向于以亲社会或退缩的方式回应同龄人。 的 本申请中提出的研究旨在扩展我们的发现 幼儿行为维度与学前教育的关系 社会行为与脑电的中介作用 不对称 目前的赠款将集中在两个独立的儿童样本， 在四个月大的时候， 被认为与行为抑制有关的特征。 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。 在每个年龄段，行为反应的测量， 记录了新事件。 在每个年龄段，脑电活动（EEG） 记录了每个受试者的数据。 我们建议看到这两个队列时， 孩子们四岁。届时，每个孩子都将被视为 两次 一次是和另外三个人一起参加同性四重奏， 记录EEG的时间。根据我们以前的工作， 我们对四岁的儿童进行了100%的抽样调查， 气质和额叶脑电不对称将预测社交退缩， 四岁时的社会能力。

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We have reported that social withdrawal is a behavioral 'marker' of social anxiety in early childhood and that socially withdrawn children are less confident and competent in their interactions with peers.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 And, we have documented that specific patterns of infant temperament are associated with withdrawn and inhibited behavior during the preschool period.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are associated with the valence of affective response and the child's disposition to respond in a pro-social or withdrawn manner to peers.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.
