Abstract:
The paper outlines some of the broad architectural implications of the modularity thesis, and reports on an attempt to test for them. The method involved analysing 472 functional magnetic resonance imaging experiments in eight cognitive domains to discover which brain regions co-operated with which others, under what conditions. The results indicate that the same brain regions contribute to functions across various cognitive domains, but in each domain co-operate with one another in different patterns. This does not appear to be compatible with the modularity thesis. The paper discusses the implications of the finding for the best approach to the design and implementation of intelligent systems in general, and of language-using robots in particular. Implications for the best approach to analysing and modelling cognitive functions will also be discussed.Keywords: modularity; functional connectivity; functional decomposition; cognitive modelling; neural redeployment
