We report the performance of a herpes simplex encephalitis patient, EA, who shows a dissociation between poor performance for living things and spared performance for sensory quality categories, when appropriate measures are taken to control for baseline differences among categories in task difficulty and when we eliminate the contribution of visual processing deficits in the recognition of objects. This pattern of performance is problematic for theories of category-specific deficits that are based on the assumption that these deficits reflect selective damage to modality-specific semantic subsystems but is consistent with domain-specific accounts and theories based on the assumption that the structure of conceptual knowledge reflects the correlational structure among object properties.
我们报告了一位单纯疱疹性脑炎患者EA的表现。当采取适当措施控制任务难度中各类别之间的基线差异，并且消除视觉处理缺陷对物体识别的影响时，该患者在生物类别上表现较差，而在感官质量类别上表现正常，二者存在分离。这种表现模式对于基于特定类别缺陷反映对特定模态语义子系统的选择性损伤这一假设的理论来说是个问题，但与基于概念知识结构反映物体属性之间相关结构这一假设的特定领域解释和理论是一致的。
