我们报告的情况下，一个病人，A. Z，患有难治性语义处理障碍采用多个口语词-书面词匹配范式，考察了她对地名广义专有名词范畴的理解。除了对时间因素敏感外，A.Z.当从一系列地理位置接近而不是遥远的地方选择目标时，准确识别国家或城市名称的能力明显较差。即使在识别近端和远端的英国城镇时，也观察到地理接近和位置的影响，但不太知名的美国州。这些近距离和远距离的影响归因于在具有共享神经回路的表征中不应性的积累。我们的研究结果揭示了一个以前没有记录的细粒度组织在这个领域的语义空间。有人认为，关于地理邻近的信息不能用纯粹的语言或视觉来编码。因此，我们提出存在一个单独的模块的空间编码信息的概念知识。
We report the case of a patient, A.Z., with a refractory disorder of semantic processing. Using a number of spoken word-written word matching paradigms, her comprehension of the broad proper nouns category of place names was investigated. In addition to being sensitive to temporal factors, A.Z.'s ability to identify country or city names accurately was significantly worse when selecting a target from an array of geographically close rather than distant places. The influence of geographical proximity and location was observed even when identifying proximal and distal English towns, but not with less well-known American states. These close and distant effects are attributed to the build-up of refractoriness in representations with shared neural circuitry. Our findings reveal a previously undocumented level of fine-grain organization in this domain of semantic space. It is argued that information about geographical proximity cannot be encoded in purely verbal or visual terms. Consequently, we propose the existence of a separate module of spatially encoded information within conceptual knowledge.
