DESCRIPTION (provided by applicant): Human sociability depends fundamentally on our ability to communicate and comprehend non-verbal affective information. It is easy to appreciate the importance of facial expression to the human experience by simply observing an infant's rapid response to a smiling parent. The goals of the first study proposed are the following: (1) to document developmental change in facial affect discrimination beginning at the age of 4 years old; and (2) utilizing functional magnetic resonance imaging (fMRI), the relationship between developmental changes in the neural architecture underlying facial affect discrimination and developmental change in the ability to discriminate facial affect will be delineated. Taken together these studies will provide critical information regarding normal developmental change in the neural and cognitive/perceptual systems devoted to processing affective information. The final study proposed will utilize fMRI to understand developmental change in a fundamental form of nervous system plasticity, i.e. habituation. Attenuation of brain activity following repeated exposure of a stimulus, the signature of habituation, in the neural systems mediating affective experience may be an important indicator of the fidelity of the human affective processing system. These studies have broad implications for our understanding of childhood onset psychiatric disorders, and certain neurodevelopmental disorders, e.g. autism, which grossly impair social and affective behaviors.

描述（由申请人提供）：人类的社交能力从根本上取决于我们沟通和理解非语言情感信息的能力。只需观察婴儿对微笑的父母的快速反应，就很容易理解面部表情对人类体验的重要性。第一项研究的目标如下：（1）记录从 4 岁开始的面部情感辨别的发展变化； (2)利用功能磁共振成像（fMRI），将描绘面部情感辨别背后的神经结构的发育变化与辨别面部情感的能力的发育变化之间的关系。总的来说，这些研究将提供有关致力于处理情感信息的神经和认知/感知系统正常发育变化的关键信息。拟议的最终研究将利用功能磁共振成像来了解神经系统可塑性基本形式的发育变化，即习惯化。在介导情感体验的神经系统中，反复受到刺激后大脑活动的减弱（习惯化的特征）可能是人类情感处理系统保真度的重要指标。这些研究对于我们理解儿童期发病的精神疾病和某些神经发育障碍（例如神经发育障碍）具有广泛的意义。自闭症，严重损害社交和情感行为。
