EMOTION, FACIAL EXPRESSION, AND ANS ACTIVITY

这两个意象任务，过去的情感体验是重温和 定向面部动作任务，要求受试者产生 面部肌肉动作的特定模式将用于探索（1） 情绪特异性ANS活动和（2）自愿面部运动如何 产生ANS活性。 一组研究将确定ANS是否 由自愿面部运动产生的活动需要视觉反馈， 一个人自己或他人的表达和认知标签， 或者是面部肌肉的本体感受反馈。 另一 一组实验将确定特定于情绪的ANS活动是否 当情绪强度变化时，两种情绪同时发生， 两种情绪相继出现 情绪特异性ANS的证据 模式将与情绪相关的疾病有关，包括 情感泛滥的心理障碍，如抑郁症，和身体 涉及ANS器官系统并与情绪有关的疾病 (e.g.,高血压-愤怒）。 这些发现可能有助于诊断 这些疾病，了解其病因和维护，并跟踪 治疗改善。

Both an imagery task in which past emotional experiences are relived and a directed facial action task in which subjects are requested to produce specific patterns of facial muscular actions will be used to explore (1) emotion-specific ANS activity and (2) how voluntary facial movements can produce ANS activity. One set of studies will determine whether ANS activity generated by voluntary facial movement requires visual feedback on one's own or antoher's expressions and the cognitive labels that may be instigated, or proprioceptive feedback from the facial muscles. Another set of experiments will determine whether emotion-specific ANS activity is preserved when emotion intensity varies, two emotions occur simultaneously, and two emotions occur sequentially. Evidence of emotion-specific ANS patterning would be relevant to emotion-related illnesses, including the affect-flooded psychological disorders such as depression, and the physical disorders that involve ANS organ systems and have been linked to emotion (e.g., hypertension--anger). The findings could be useful in diagnosing such disorders, understanding their etiology and maintenance, and tracking therapeutic improvement.
