How do literate minds differ from illiterate minds? (not talking about intelligence, I mean externalised thot)?

You should see the cat scans and mris on this. It is amazing at the difference in brain activity and when you through emotion in there it is really fascinating. Illiterate people have just as many big and small emotions as the next guy and this sets off a completely different area in the brain. National geographic recently did an article on it and psychologists have been examining it for centuries. Just because some one is illiterate tho doesn't mean they don't have the thoughts of how to build an engine or perform cpr or other higher thought process, they just have a different if not difficult way of expressing it.
