Spontaneous facial expression of emotion was studied in two groups of right (N = 23) and left (N = 39) brain-damaged patients and in a control group of normal subjects (N = 28). To elicit emotions four short movies, constructed to produce positive, negative or neutral emotional responses, were used. The method used to assess the facial expression of emotions was the Facial Action Coding System. Brain-damaged patients showed less facial responses to emotional stimuli than normal controls, but no difference was observed between subjects with right and left-sided lesions either with global or disaggregated data analyses, inconsistent with the hypothesis of a specialization of the right hemisphere for facial emotional expressions. An unexpected difference was observed in response to the unpleasant movie. Both normal controls and left brain-damaged patients often averted their gaze from the screen when unpleasant material was displayed, whereas right brain-damaged patients rarely showed gaze aversion. This finding suggests that the degree of emotional involvement or manner of coping with stressful input may be reduced as a result of right brain damage.
对两组右脑损伤患者（N = 23）和左脑损伤患者（N = 39）以及一组正常受试者对照组（N = 28）的自发面部情绪表达进行了研究。为了引发情绪，使用了四部短片，这些短片旨在产生积极、消极或中性的情绪反应。用于评估情绪面部表情的方法是面部动作编码系统。脑损伤患者对情绪刺激的面部反应比正常对照组少，但无论是进行整体数据分析还是分类数据分析，右侧和左侧病变的受试者之间均未观察到差异，这与右半球对面部情绪表达具有专门化功能的假设不一致。在观看不愉快的影片时观察到了一个意外的差异。当展示不愉快的画面时，正常对照组和左脑损伤患者经常将目光从屏幕上移开，而右脑损伤患者很少表现出目光回避。这一发现表明，右脑损伤可能会导致情绪参与程度或应对压力性输入方式的降低。
