This study examined the expression and perception of facial emotion in patients with unilateral cerebrovascular pathology. Subjects were 12 right brain-damaged (RBD), 15 left brain-damaged (LBD) aphasic, and 16 normal control (NC) right-handed males. Expressions were elicited during posed and spontaneous conditions. Both positive and negative emotions were studied. RBDs were significantly impaired, relative to LBDs and NCs, in expressing and perceiving facial emotion. There were no group differences as a function of condition, but there were differences as a function of emotional valence. Qualitative performance differences also were observed. There was no evidence that the ability to produce a particular emotion was related to the ability to identify the same emotion. Overall, these findings support the notion that the right cerebral hemisphere is dominant for expressing and perceiving facial emotion.
本研究调查了单侧脑血管病变患者面部情绪的表达与感知。研究对象为12名右脑损伤（RBD）患者、15名左脑损伤（LBD）失语患者以及16名正常对照（NC）的右利手男性。表情在摆拍和自然状态下诱发。对积极和消极情绪均进行了研究。相对于LBD患者和NC患者，RBD患者在面部情绪的表达和感知方面明显受损。不存在因条件不同而产生的组间差异，但存在因情绪效价不同而产生的差异。还观察到了定性的表现差异。没有证据表明产生特定情绪的能力与识别相同情绪的能力相关。总体而言，这些发现支持了右脑半球在面部情绪的表达和感知中占主导地位这一观点。
