The study of patients with various types of brain damage has revealed that different part of the brain are associated with ( i.e. control) different functions. In other words, it is possible to localize different functions in the brain as indicated in functions in the brain as indicated in figure I.
A language disorder resulting from brain damage is called aphasia, and a notable point is that this sort of brain damage almost always occurs in the left side of the brain (the left hemisphere). Damage to similar areas in the right hemisphere usually gives rise to entirely different deficits that have little to do with language. Aphasics who lose their language completrely are said to suffer from global aphasia and while in many cases the brain damage is extensive enough to affect other intellectual faunctions sometimes patients retian a good many of the cognitive capacitites they had before the injury . In particular, although these patients are unable to produce or understand language, they can often solve intellectual puzzeles which don’t rely on language.
As we have seen, Chomsky Claims that linguistic competence is the product of a species – specific innate language faculty , remaining intact , which we have just described , is exactly what we might expect on the supposision that the language faculty is an autonomous and innate cognitive capacity.
