Capgras delusion is the belief that significant others have been replaced by impostors, robots or aliens. Although it usually occurs within a psychiatric illness, it can also be the result of brain injury or other obviously organic disorder. In contrast to patients with prosopagnosia, who cannot consciously recognize previously familiar faces but display autonomic or covert recognition (measured by skin conductance responses), people with Capgras delusion do not show differential autonomic activity to familiar compared with unknown faces. This challenges traditional models of the way faces are identified and presents some epistemological questions concerning identity. New data also indicate that, contrary to previous evidence, covert recognition can be fractionated into autonomic and behavioural/cognitive types, which is consistent with a recently proposed modification of the modal face recognition model.
卡普格拉妄想症是指患者坚信重要他人已被冒名顶替者、机器人或外星人所取代。尽管它通常发生在精神疾病中,但也可能是脑损伤或其他明显的器质性疾病导致的。与面孔失认症患者不同,面孔失认症患者无法有意识地识别以前熟悉的面孔,但会表现出自主或隐蔽的识别(通过皮肤电反应测量),而患有卡普格拉妄想症的人在面对熟悉面孔与陌生面孔时,不会表现出不同的自主神经活动。这对传统的面孔识别方式模型提出了挑战,并引发了一些关于身份认同的认识论问题。新数据还表明,与之前的证据相反,隐蔽识别可以细分为自主型和行为/认知型,这与最近提出的对面孔识别模态模型的修改是一致的。
