DEVELOPMENT OF VISUAL ATTENTION

这是对ADAMHA研究科学家发展奖的请求， 第二级。本建议的目的是允许校长 研究人员将在心理健康研究领域发展自己的事业。这将是 通过将国际和平研究所目前的研究领域扩展到新的领域来实现 进一步加强PI与多名心理学研究人员的合作 健康和酗酒领域，并提供持续的专业人员 研究进展。研究目标的目标是 研究青少年持续的内源性注意的发展 婴儿，并将持续关注的发展趋势与 同时发生心率(HR)变化。具体目标是：1)学习 持续注意相对于其他视觉的选择性 系统；2)研究持续时间内的信息加工 注意；3)扩展心率决定的视觉注意的研究 新刺激和自然刺激条件的阶段。这些目标 形成拟议的RSDA支持的主要目标。的两个次要目标 研究科学家发展奖是为了建立合作 两性关系。这些目标是：4)研究儿童的注意障碍 呼吸窘迫综合征和胎儿酒精综合征，以及 建立注意力障碍的动物模型；5)改进 涉及的方法学和测量特征 呼吸性窦性心律失常的测量(RSA；心脏变异性 发生在呼吸频率上的速率)。该研究涵盖了基本的 婴幼儿持续性注意发展的研究进展 对持续注意的研究可能为研究持续注意提供“模型准备” 注意障碍的发展发现在多动症，自闭症， 还有弱智儿童。国际和平协会的新合作项目将 开始探索持续注意研究在 患有注意力病态的婴儿。专业发展和 私人投资公司将通过直接学习来促进新知识的获得 参与这项研究。这个RSDA应用程序尤其 与行为科学研究的目标和计划相关 美国国立理工学院基础科学分部 心理健康。

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.
