REGIONAL BRAIN FUNCTION AND EMOTIONAL REACTIVITY

描述（申请人摘要）：本项目提出使用 多种生理学方法：1）开发客观测量 情感反应的特质样模式，2）为了更好地理解 情绪时程个体差异之间的关系 反应，以及情绪体验背后的神经基质。 尽管情绪研究的主体越来越多，但很少有客观的，非自我报告的 情感体验的诱导是存在的，但做的工作很少。 研究对情绪激发物的反应的时间过程。 的时间 情绪的过程可能是理解的一个非常重要的变量 情感风格的个体差异。 例如， 经历负面情绪的时间越长，可能越容易变得焦虑， 郁闷. 为了实现第一个目标，制定一个客观的衡量标准， 特质情感反应，情绪调节惊吓的稳定性 将对反应进行评估，以确定该范例是否适合 可靠性作为一个类似于性状的指标。 第二个目标，理解 情绪的计时，将使用具有极端不对称性的主题， 额叶EEG激活（先前显示与状态和特质相关 影响），以检查皮质和 皮质下脑激活（用FMR1测量） 充满感情的照片

DESCRIPTION (Applicant's abstract): This project proposes the use of multiple physiological methods to: 1) develop an objective measure of trait-like patterns of affective responding, and 2) to better understand the relations between individual differences in the time course of emotional reactions, and the neural substrates underlying emotional experience. Despite the growing body of emotion research, few objective, non-self-report induces of emotional experience exist, and very little work has been done examining the temporal course of responses to an emotion elicitor. The time course of emotions may be a very important variable in understanding individual differences in affective style. For example, individuals who experience negative emotions longer may be more likely to become anxious or depressed. To address the first goal, developing an objective measure of trait affective responding, the stability of the emotion-modulated startle response will be assessed to determine whether this paradigm shows suitable reliability for use as a trait -like index. The second goal, understanding the chronometry of emotions, will use subjects with extreme asymmetry of frontal EEG activation (shown previously to be related to state and trait affect) to examine individual differences in the time course of cortical and subcortical brain activation (measured with FMRl) in response to affectively-laden pictures.
