An implementation of Bruce and Young's (1986) functional model of face recognition is used to examine patterns of covert face recognition previously reported in a prosopagnosic patient, PH. Although PH is unable to recognize overly the faces of people known to him, he shows normal patterns of face processing when tested indirectly. A simple manipulation of one set of connections in the implemented model induces behaviour consistent with patterns of results from PH obtained in semantic priming and interference tasks. We compare this account with previous explanations of covert recognition and demonstrate that the implemented model provides the most natural and parsimonious account available. Two further patients are discussed who show deficits in person perception. The first (MS) is prosopagnosic but shows no covert recognition. The second (ME) is not prosopagnosic, but cannot access semantic information relating to familiar people. The model provides an account of recognition impairments which is sufficiently general also to be useful in describing these patients.
采用布鲁斯和扬（1986年）人脸识别功能模型的一个实施方案，来研究之前在面孔失认症患者PH身上所报告的隐蔽人脸识别模式。尽管PH无法完全认出他认识的人的面孔，但在间接测试时，他表现出正常的面部处理模式。对已实施模型中的一组连接进行简单操作，会产生与在语义启动和干扰任务中从PH获得的结果模式一致的行为。我们将这种解释与之前对隐蔽识别的解释进行比较，并证明已实施的模型提供了现有最自然、最简洁的解释。还讨论了另外两名在人物感知方面存在缺陷的患者。第一个（MS）是面孔失认症患者，但没有表现出隐蔽识别能力。第二个（ME）不是面孔失认症患者，但无法获取与熟悉的人相关的语义信息。该模型提供了一种识别障碍的解释，其通用性足以用于描述这些患者。
