We report the case of a woman who displayed impaired object recognition following a severe head injury. Her elementary visual functions were substantially preserved, allowing her a coherent percept. On the other hand, she was impaired in accessing stored knowledge from both visual and verbal input. In particular, she showed a dramatic dissociation between fully preserved access to functional knowledge, and severely impaired access to perceptual knowledge so that she could describe what objects are for, but not how they are. Our findings from this case suggest that different categories of object knowledge are represented independently in separate units within the semantic system.
我们报告了一名女性病例，她在遭受严重头部损伤后出现了物体识别障碍。她的基本视觉功能基本保留，使她能够形成连贯的感知。另一方面，她在从视觉和语言输入中获取存储的知识方面存在障碍。特别是，她在完全保留对功能知识的获取与严重受损的对感知知识的获取之间表现出显著的分离，以至于她能够描述物体的用途，但无法描述其外观。我们从该病例中得出的研究结果表明，不同类别的物体知识在语义系统内的不同独立单元中独立表征。
