本文比较了帕金森病（PD，n = 12）患者和年龄匹配的健康对照者（n = 12）的自发和摆姿势表情。PD患者的面部表情的强度和数量预计会减少自发但不构成的表情。情绪刺激是从电影中选择的视频剪辑，持续时间2-5分钟，旨在引起幸福，悲伤，恐惧，厌恶或愤怒的感觉。使用Ekman和弗里森（1978）的面部动作编码系统（FACS）对面部运动进行编码。此外，参与者在9点Likert量表上评估他们的情绪体验。PD组在观看电影时的整体面部反应明显低于对照组。当将患有更严重疾病的PD参与者与患有轻度疾病的参与者和对照组进行比较时，发现了预测的X组条件（自发与姿势）对微笑强度的相互作用效应。相比之下，两组的情绪体验评分相似。抑郁症与情绪评分呈正相关，但与面部活动的测量无关。自发的面部表情似乎是选择性地影响PD，而构成的表达和情感体验保持相对完整。(JINS，1996，2，383-391.）
Abstract Spontaneous and posed emotional facial expressions in individuals with Parkinson's disease (PD, n – 12) were compared with those of healthy age-matched controls (n = 12). The intensity and amount of facial expression in PD patients were expected to be reduced for spontaneous but not posed expressions. Emotional stimuli were video clips selected from films, 2–5 min in duration, designed to elicit feelings of happiness, sadness, fear, disgust, or anger. Facial movements were coded using Ekman and Friesen's (1978) Facial Action Coding System (FACS). In addition, participants rated their emotional experience on 9-point Likert scales. The PD group showed significantly less overall facial reactivity than did controls when viewing the films. The predicted Group X Condition (spontaneous vs. posed) interaction effect on smile intensity was found when PD participants with more severe disease were compared with those with milder disease and with controls. In contrast, ratings of emotional experience were similar for both groups. Depression was positively associated with emotion ratings, but not with measures of facial activity. Spontaneous facial expression appears to be selectively affected in PD, whereas posed expression and emotional experience remain relatively intact. (JINS, 1996, 2, 383–391.)
