发展性面孔失认症（DP）患者的面部识别能力受损。理论上，DP可能涉及面部记忆受损，面部感知受损，或两者兼而有之。所有的儿童和成人dp患者都存在记忆缺陷。所有的儿童，但不到一半的成年人有面部知觉受损。认知模型提出，人脸识别是通过一系列离散的阶段完成的，包括面部结构的感知表征，以及面部信息的编码和检索。这意味着受损的面部识别可能是由于面部感知、面部记忆或两者兼而有之。对获得性面孔失认症、自闭症谱系障碍和正常人脸识别发展的研究支持人脸感知和人脸记忆是不同过程的观点，但这种区别在发展性面孔失认症（DP）中很少得到关注。为了解决这一问题，我们测试了儿童和成人DP患者的面部感知和面部记忆。根据定义，面部记忆在DP中受损，因此所有参与者都存在记忆缺陷。然而，我们发现所有的孩子，只有一半的成年人有面部知觉受损。因此，来自成人的结果表明，面部知觉和面部记忆是可分离的，而来自儿童的结果没有提供这种分离的证据。重要的是，我们的发现提出了DP在儿童期和成年期有质的不同的可能性。我们讨论了这一发展模式的理论解释，并得出结论，纵向研究对于更好地理解面部知觉和面部记忆缺陷的发展轨迹是必要的。
Individuals with developmental prosopagnosia (DP) have impaired face recognition. In theory, DP could involve impaired face memory, impaired face perception, or both. Memory deficits were present in all of our child and adult DPs. All children, but less than half of the adults had impaired face perception. Cognitive models propose that face recognition is accomplished through a series of discrete stages, including perceptual representation of facial structure, and encoding and retrieval of facial information. This implies that impaired face recognition can result from failures of face perception, face memory, or both. Studies of acquired prosopagnosia, autism spectrum disorders, and the development of normal face recognition support the idea that face perception and face memory are distinct processes, yet this distinction has received little attention in developmental prosopagnosia (DP). To address this issue, we tested the face perception and face memory of children and adults with DP. By definition, face memory is impaired in DP, so memory deficits were present in all participants. However, we found that all children, but only half of the adults had impaired face perception. Thus, results from adults indicate that face perception and face memory are dissociable, while the results from children provide no evidence for this division. Importantly, our findings raise the possibility that DP is qualitatively different in childhood versus adulthood. We discuss theoretical explanations for this developmental pattern and conclude that longitudinal studies are necessary to better understand the developmental trajectory of face perception and face memory deficits in DP.
