The organisation of conceptual knowledge in the brain: The future's past and some future directions.
نویسندگان
چکیده
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.

متن کاملKnowledge Translation in Healthcare – Towards Understanding its True Complexities; Comment on “Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation”
This commentary argues that to fully appreciate the complexities of knowledge transfer one firstly has to distinguish between the notions of “data, information, knowledge and wisdom,” and that the latter two are highly context sensitive. In particular one has to understand knowledge as being personal rather than objective, and hence there is no form of knowledge that a-priori is more authoritat...
