How does the brain process information? In particular, is the cognitive portion of the brain divided up into a number of task-specific ‘modules’, each of which are devoted to a specific task, or is the brain constituted by (one or many) processing units which are flexible in their operation? Modularists, as those in the former camp are called, often appeal to a form of argument which makes use of the idea that certain cognitive characteristics appear to be dissociable from others, such that certain individuals can excel, or struggle, in distinct tasks in ways not necessarily related to the complexity of the task, or proportional to their general intelligence. To this end, Williams Syndrome and – at the other end of the spectrum – SLI are invoked to support a modular conception of language faculties, and autism is sometimes (questionably) invoked in support of the view that the capacity to deploy a theory of mind is modular.
Face-recognition is another commonly-cited, and perhaps less-controversial, candidate for being a modular system. Continue reading “Why Some People Will Never Forget a Face”
