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.

这是对ADAMHA研究科学家发展奖的申请， 二级。 这项建议的目的是让校长 研究员，以发展他的职业生涯在心理健康研究。 这将 通过将PI当前的研究领域扩展到新的领域来完成 进一步合作的PI与几个研究人员在精神 健康和酗酒领域，并提供持续的专业 研究的发展。 研究目标的目的是 研究年轻人持续、内源性注意力的发展 婴儿，并与持续关注的发展趋势， 心率（HR）变化。 具体目的是：1）研究 持续注意力相对于其他视觉的选择性 系统;. 2)为了研究在持续的 3）扩展心率定义的视觉注意的研究 新的刺激和自然的刺激条件的阶段。 这些目标 形成了拟议的RSDA支持的主要目标。两个次要目标 研究科学家发展奖是为了建立合作 关系。 这些目标是：4）研究注意功能障碍， 呼吸窘迫综合征和胎儿酒精综合征婴儿， 建立注意力功能障碍的动物模型; 5）改善 方法和计量特点 呼吸性窦性心律不齐（RSA;心脏变异性）的测量 呼吸频率（respiratory frequency）。 研究内容涵盖基础 婴儿持续注意力发展的研究 对持续注意力的研究可能为 注意力障碍的发展在多动，自闭症， 和弱智儿童 PI的新合作项目将 开始探索持续注意研究在 注意力异常的婴儿 专业发展与 PI获取新知识将通过直接 参与这项研究。 RSDA应用程序特别是 与行为科学研究的目标和计划相关 国家自然科学研究所基础科学处分支 心理健康
