refers to a hypothesized structure in the human brain (anatomical module) or cognitive system (functional module) that some psycholinguists (e.g., Steven Pinker) claim contains innate capacities for language. According to Jerry Fodor the sine qua non of modularity is information encapsulation; that is, the module is immune from information from other sources not directly associated with language processing There is currently ongoing debate about this in the field of cognitive science and neuroscience.
