Impairments in the identification of facial and vocal emotional expression were demonstrated in a group of patients with ventral frontal lobe damage who had socially inappropriate behaviour. The expression identification impairments could occur independently of perceptual impairments in facial recognition, voice discrimination, or environmental sound recognition. The face and voice expression problems did not necessarily occur together in the same patients, providing an indication of separate processing. Poor performance on both expression tests was correlated with the degree of alteration of emotional experience reported by the patients. There was also a strong positive correlation between the degree of altered emotional experience and the severity of the behavioural problems (e.g. disinhibition) found in these patients. A comparison group of patients with brain damage outside the ventral frontal lobe region, without these behavioural problems, was unimpaired on the face expression identification test, was significantly less impaired at vocal expression identification and reported little subjective emotional change. The expression identification deficits in ventral frontal patients may contribute to the abnormal behaviour seen after frontal lesions, and have implications for rehabilitation.
一组患有腹侧额叶损伤且存在社交不适当行为的患者表现出面部和声音情感表达识别能力受损。这种表达识别障碍可能独立于面部识别、语音辨别或环境声音识别方面的感知障碍而出现。面部和声音表达问题不一定会在同一患者中同时出现,这表明存在独立的处理过程。两项表达测试的表现不佳与患者报告的情感体验改变程度相关。情感体验改变程度与这些患者中发现的行为问题(如去抑制)的严重程度之间也存在很强的正相关。一组在腹侧额叶区域以外有脑损伤但没有这些行为问题的患者作为对照组,在面部表情识别测试中未受损,在声音表情识别方面受损明显较轻,并且报告的主观情感变化很小。腹侧额叶患者的表达识别缺陷可能导致额叶损伤后出现的异常行为,并对康复有影响。
