We review the development and current status of theories of the organisation and representation of conceptual knowledge in the human brain. The currently known facts from optic aphasia, category-specific semantic deficits, and functional neuroimaging are consistent with a framework in which the first-order constraint on the organisation of conceptual knowledge is domain. Data from functional neuroimaging suggests additionally a framework characterised by both domain- and modality-specific constraints. Work in congenital disorders and in apraxia indicate that the content of conceptual knowledge is not exhausted by modality-specific input/output processes. It is concluded that future empirical and theoretical work on the organisation and representation of conceptual knowledge will profit from a reorientation of the problem from the organisation of distinct processing systems to the content of information represented internal to such systems.
我们回顾了人类大脑中概念知识的组织和表示理论的发展和现状。来自失读症、范畴特异性语义缺陷和功能神经影像学的现有事实与一个框架一致，该框架对概念知识的组织的一阶约束是域。来自功能神经影像学的数据还表明了一个以域和模态特异性约束为特征的框架。先天性疾病和失用症的研究表明，概念知识的内容并没有穷尽于模态特异性的输入/输出过程。因此得出结论，未来关于概念知识的组织和表示的实证和理论工作将从组织不同的处理系统的问题重新定向到代表这些系统内部的信息的内容。
