Is there a cognitive disorder that is characterized by an inability to categorize? Ideally, I"m trying to find a disorder where someone is unable to categorize even the simplest of things.



For instance, they couldn't call a fern a plant because they have no idea that it belongs to the plant category; or perhaps they couldn't even call a person a human because they cannot conceive of all of us falling under the category of human; and thus cannot stereotype and sees everything individually?
