This is a request for an ADAMHA, Research Scientist Development Award, Level II. The purpose of this proposal is to allow the Principal Investigator to develop his career in mental health research. This will be done by extending the current research areas of the PI to new ones furthering collaboration of the PI with several researchers in the mental health and alcoholism field, and providing for continuing professional development of the research. The objectives of the research goals are to study the development of sustained, endogenous attention in young infants, and to relate developmental trends in sustained attention to concurrent heart rate (HR) changes. The specific aims are: 1) To study the selectivity of sustained attention in relation to other visual systems;. 2) To study information processing occurring during sustained attention; 3) To extend the study of heart-rate-defined visual attention phases to new stimuli and naturalistic stimulus conditions. These aims form the major goals of the proposed RSDA support. Two secondary aims of the Research Scientist Development award are to establish collaborative relationships. These aims are: 4) To study attentional dysfunctions in Respiratory Distress Syndrome and Fetal Alcohol Syndrome infants, and to develop an animal model of attentional dysfunctions; 5) To improve methodological and measurement characteristics involved in the measurement of respiratory sinus arrhythmia (RSA; variability in heart rate occurring at the respiration frequency). The research covers basic research in the development of sustained attention in infants The research on sustained attention may provide a "model preparation" for the development of attentional disabilities found in hyperactive, autistic, and retarded children. The new collaborative projects of the PI will begin to explore the application of the sustained attention research to infants with attention pathologies. Professional development and the acquisition of new knowledge by the PI will be furthered by direct participation in this research. This RSDA application is particularly relevant to the goals and programs in the Behavioral Sciences Research Branch, of the Division of Basic Sciences, at the National Institute of Mental Health.

这是获得Adamha，研究科学家发展奖的要求， II级。 该提议的目的是允许校长 研究人员发展了他在心理健康研究领域的职业。 这会 可以通过将PI的当前研究领域扩展到新的来完成 在心理上与几位研究人员的PI合作进一步合作 健康和酒精中毒领域，并为继续专业的专业人士提供 研究的发展。 研究目标的目标是 研究年轻人的持续内源性注意的发展 婴儿，并将持续关注的发展趋势与 并发心率（HR）改变。 具体目的是：1）学习 相对于其他视觉的持续关注的选择性 系统; 2）研究持续期间发生的信息处理 注意力; 3）扩展心率定义的视觉注意力的研究 新刺激和自然主义刺激条件的阶段。 这些目标 构成拟议的RSDA支持的主要目标。两个次要目标 研究科学家发展奖是建立合作的 关系。 这些目的是：4）研究注意力障碍 呼吸窘迫综合征和胎儿酒精综合征婴儿，以及 发展注意力障碍的动物模型； 5）改进 涉及的方法和测量特征 呼吸窦性心律不齐的测量（RSA；心脏变异性 呼吸频率下发生的速率）。 该研究涵盖了基本 研究婴儿持续关注的研究 对持续关注的研究可能会为 在多动，自闭症中发现的注意力障碍的发展， 和智障的孩子。 PI的新合作项目将 开始探索持续关注研究的应用 患有注意病理的婴儿。 专业发展和 PI获取新知识将被直接促进 参与这项研究。 此RSDA申请特别是 与行为科学研究中的目标和计划有关 基础科学司的分支机构 心理健康。
