Blunted facial expressions and diminished expressions of emotional prosody associated with Parkinson's disease (PD) could be attributed to motor rigidity/akinesia. Although impaired recognition of emotional faces and prosody in PD suggests emotional dysfunction is not entirely motor-efferent, comprehension might depend upon imitation with motor feedback. Thus, to learn if patients with PD have an emotional conceptual defect, we examined their ratings for the emotional connotations of words on a 1-9 scale for valence and arousal. When compared to control participants the valence (positive-negative) and arousal (excited-calm) ratings of the PD patients were blunted, but their ratings of the control expense words (expensive-cheap) were not. These blunted emotion ratings suggest that patients with PD have a degradation of their emotional conceptual-semantic system.
与帕金森病（PD）相关的面部表情迟钝和情感韵律表达减弱可能归因于运动僵硬/运动不能。尽管帕金森病患者对情感面孔和韵律的识别受损表明情感功能障碍并不完全是运动传出性的，但理解可能依赖于带有运动反馈的模仿。因此，为了了解帕金森病患者是否存在情感概念缺陷，我们让他们以1 - 9分的量表对单词的情感内涵进行效价和唤醒度评分。与对照组参与者相比，帕金森病患者的效价（积极 - 消极）和唤醒度（兴奋 - 平静）评分较低，但他们对对照费用类单词（昂贵 - 便宜）的评分没有差异。这些减弱的情感评分表明帕金森病患者的情感概念语义系统出现了退化。
