EMOTION, FACIAL EXPRESSION, AND ANS ACTIVITY

既是重温过去情感经历的表象任务，也是 指导性面部动作任务，要求受试者产生 将使用面部肌肉动作的特定模式来探索(1) 特定于情绪的ANS活动以及(2)自愿面部运动如何 产生ANS活动。一组研究将确定ANS是否 面部自主运动产生的活动需要视觉反馈 自己或她的表情和认知标签，可能是 面部肌肉的刺激或本体感觉反馈。另一个 一组实验将确定特定情绪的ANS活动是否 当情绪强度变化时，两种情绪同时发生， 而两种情绪是相继发生的。情绪特异性ANS的证据 图案化将与情绪相关的疾病相关，包括 情感泛滥的心理障碍，如抑郁，以及身体上的 涉及ANS器官系统并与情绪有关的障碍 (例如，高血压--愤怒)。这些发现可能有助于诊断 这类疾病，了解其病因和维护，并跟踪 治疗上的进步。

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.
