Anecdotal evidence suggests a relation between impaired spatial (navigational) processing and developmental prosopagnosia. To address this formally, we tested two aspects of topographic processing - that is, perception and memory of mountain landscapes shown from different viewpoints. Participants included nine individuals with developmental prosopagnosia and 18 matched controls. The group with developmental prosopagnosia had no difficulty with topographic perception, but was reliably poorer in the retention of topographic information. Additional testing revealed that this did not reflect a general deficit in visual processing or visual short-term memory. Interestingly, a classical dissociation could be demonstrated between impaired face memory and preserved topographic memory in two developmental prosopagnosics. We conclude that impairments in topographic memory tend to co-occur with developmental prosopagnosia, although the underlying functions are likely to be independent.
轶事证据表明空间（导航）处理受损与发育性面孔失认症之间存在关联。为了正式探讨这一问题，我们测试了地形处理的两个方面，即从不同视角展示的山地景观的感知和记忆。参与者包括9名患有发育性面孔失认症的个体和18名匹配的对照组。患有发育性面孔失认症的组在地形感知方面没有困难，但在地形信息的保留方面明显较差。进一步测试表明，这并非反映出视觉处理或视觉短期记忆方面的普遍缺陷。有趣的是，在两名发育性面孔失认症患者中，可以证明面孔记忆受损与地形记忆保留之间存在经典的分离。我们得出结论，地形记忆受损往往与发育性面孔失认症同时出现，尽管其潜在功能可能是独立的。
