几个案例研究的结果表明，双侧杏仁核损伤会损害面部表情中的情绪识别，特别是恐惧。然而，一项研究没有发现这种损害，而且，一般来说，由于采用的刺激和任务不同，很难进行跨研究的比较。在一项合作研究，以促进这种比较，我们在这里报告的识别情感面部表情的9名受试者双侧杏仁核损伤，使用敏感和定量评估。与对照组相比，受试者作为一个群体在识别恐惧方面显着受损，尽管个人表现从严重受损到基本正常不等。大多数受试者除了恐惧外，还在几种负面情绪上受损，但没有受试者在识别快乐表情方面受损。对反应一致性的分析表明，对恐惧的识别受损不能简单地归因于将恐惧误认为另一种情绪。虽然目前还不清楚为什么有些杏仁核受损的受试者在我们的任务中没有受损，但总体上，结果与杏仁核在触发与面部表情发出的威胁和危险信号相关的知识方面起着重要作用的想法一致。(C)1999爱思唯尔科技有限公司。保留所有权利。
Findings from several case studies have shown that bilateral amygdala damage impairs recognition of emotions in facial expressions, especially fear. However, one study did not find such an impairment, and, in general, comparison across studies has been made difficult because of the different stimuli and tasks employed. In a collaborative study to facilitate such comparisons, we report here the recognition of emotional facial expressions in nine subjects with bilateral amygdala damage, using a sensitive and quantitative assessment. Compared to controls, the subjects as a group were significantly impaired in recognizing fear, although individual performances ranged from severely impaired to essentially normal. Most subjects were impaired on several negative emotions in addition to fear, but no subject was impaired in recognizing happy expressions. An analysis of response consistency showed that impaired recognition of fear could not be attributed simply to mistaking fear for another emotion. While it remains unclear why some subjects with amygdala damage included here are not impaired on our task, the results overall are consistent with the idea that the amygdala plays an important role in triggering knowledge related to threat and danger signaled by facial expressions.
