Quo Vadis Modularity in the 1990s?

Abstract

Our commentary on these four interesting articles will focus on two issues. First, we ask whether the notion of modularity is doing any work for theorists in the 1990s. Despite our theoretical leanings, we strongly prefer Fodorís (1983) precise definition of a module. Once one weakens Fodorís criteria, as these four papers do in various ways, then the notion of modularity becomes loosely descriptive rather than retaining the strong theoretical base that leads to precise predictions about what can or cannot interact with what in the human brain. Second, even when one relaxes Fodorís criteria to create a weaker notion of modularity, we argue that, given everything that is now known about postnatal neocortical development, it is more likely that modularity is the outcome of development rather than its starting state.
