本研究的目的是考虑效价、运动方向（即，接近/撤回），和唤醒对单侧皮质病变患者的面部情绪感知。我们还研究了病变侧，部位和大小对情绪感知的影响。受试者为30名右半球损伤（RHD）和30名左半球损伤（LHD）的男性患者，局灶性病变主要限于额叶、颞叶或顶叶。患者组在人口统计学和临床神经学变量方面具有可比性。研究人员测试了受试者对四种面部表情的照片进行匹配的能力：快乐、悲伤、恐惧和愤怒。总体而言，RHD患者在感知面部情绪方面比LHD患者明显受损。病变侧，而不是网站，与运动方向和效价尺寸。相对于LHD患者，RHD患者在处理消极和退缩情绪方面存在特定缺陷;积极/接近情绪没有组间差异。病灶大小与情绪感知的准确性无显著相关性。
The purpose of this study was to consider the effects of valence, motoric direction (i.e., approach/withdrawal), and arousal on the perception of facial emotion in patients with unilateral cortical lesions. We also examined the influence of lesion side, site, and size on emotional perception. Subjects were 30 right-hemisphere-damaged (RHD) and 30 left-hemisphere-damaged (LHD) male patients with focal lesions restricted primarily to the frontal, temporal, or parietal lobe. Patient groups were comparable on demographic and clinical neurological variables. Subjects were tested for their ability to match photographs of four facial emotional expressions: happiness, sadness, fear, and anger. Overall, RHD patients were significantly more impaired than LHD patients in perceiving facial emotion. Lesion side, but not site, was associated with motoric direction and valence dimensions. RHD patients had specific deficits relative to LHD patients in processing negative and withdrawal emotions; there were no group differences for positive/approach emotions. Lesion size was not significantly correlated with accuracy of emotional perception.
