INFANT COMPETENCE: BEHAVIOR AND ELECTROPHYSIOLOGY

大量早产儿将进入学习障碍期 然而，很多人会有好的结果。 而且 一定数量的有良好病史的新生儿将成为学习 禁用. 医学变量的统计检查尚未 区分能力较强和能力较弱的婴儿。 我们有 制定了婴儿行为和电生理指标 功能（BEAM）旨在解决神经行为问题 整合，以便为从新生期开始的预测提供基础 到上学的年龄。 我们现在已经研究了，在新生期，98 足月和早产新生儿无神经损伤， 发现1）高度一致的婴儿行为亚组，2）高度一致的婴儿行为亚组， 一致的婴儿电生理亚组，和3）令人印象深刻的 行为与电生理群体状态的对应关系。 这 这一发现有力地支持了我们的假设，即新生儿的功能是 通过我们的两种方法评估，可以分为稳定的亚组。 的 现在的问题是：1）98名研究婴儿能否被分组， 9个月数据时的行为和电生理预测 点（将在我们目前的补助金03年完成）？ 2)才能 测量确定了人群中行为功能的子类别 遭受了已知的神经损伤，即脑室内损伤， 出血（IVH）。 3)功能集群成员关系是否一致 从新生儿到9个月大的婴儿 4)我们能识别出 预测98名健康人的功能能力模式 研究学龄前阶段的婴儿， 电生理学？ 在未来的研究中，我们计划进一步随访 以及IVH儿童。 成功识别模式 功能能力的评估将提供（1）预测的基准， (2)更有效地利用稀缺干预措施的目标 资源

A large number of infants born prematurely will enter the learning disabled population, yet, a significant number will have good outcomes. Moreover, a certain number of neonates with good medical histories will become learning disabled. Statistical examination of medical variables has not discriminated more competent from less competent infants. We have developed measures of infant behavior (APIB) and electrophysiological functioning (BEAM) designed to get at issues of neuro-behavioral integration so as to provide a basis for prediction from the newborn period to the school age years. We have now studied, in the newborn period, 98 full term and preterm newborns free of neurological impairment and have found 1) highly consistent behavioral subgroupings of infants, 2) highly consistent electrophysiological subgroupings of infants, and 3) impressive correspondence of behavioral to electrophysiological group status. This finding strongly supports our hypothesis that newborn functioning as assessed by our 2 methods can be classified into stable subgroups. The questions at hand now are: 1) Can the 98 study infants be subgrouped and predicted behaviorally and electrophysiologically at the 9 months data point (to be completed in the 03 year of our current grant)? 2) Can our measures identify subcategories of behavioral functioning in a population having suffered a known neurological insult, namely, intraventricular hemorrhage (IVH). 3) Is there consistency of functional cluster membership from the newborn to the 9 months period in this group? 4) Can we identify and predict patterns of functional competence of the current 98 healthy study infants at the preschool period, behaviorally and electrophysiologically? In future studies we plan further follow-up of the healthy as well as the IVH children. Successful identification of patterns of functional competence will provide (1) a benchmark for prediction and (2) a target for more efficient utilization of scarce intervention resources.
