 A defining feature of mental modules, as per Fodor’s (1983) original formulation, is that they are informationally encapsulated. Information contained in each module is encapsulated from other modules and encapsulated from the information available in the cognitive system. Modules have limited cognitive interests and concerns: they operate on a strictly need-to-know basis. Because of their informationally encapsulated limited interests, ToM modules are not informed and updated by the subject’s wider set of background knowledge. It is assumed that modules work better and faster by restricting their concerns to specialized dealings with only certain topics.
