The Information also describes cases of the effect of traditional literacy on complexity/abstraction of thought.
He claims that literacy is nearly a prerequisite for things like zeroth-order logical reasoning and understanding of abstract shapes. Two examples he gives:
- Some illiterate people are told that all bears in the north are white, that Greenland is a country in the north, then they are asked what colours bears in Greenland have. They answer, "Different regions have differently coloured bears. I haven't been to Greenland. But I have seen a brown bear."
I would have said, "Based on the information you gave me, I would guess white."
- When shown a rectangle and asked what shape it is some illiterate answer things like "a door" or "a playing card" but struggle to find things doors and playing cards have in common.
I go to the abstract shapes immediately when I'm shown drawings by my son. It's almost at a point where it feels like my logical/abstract reasoning stands in the way of creativity.

But I don't know how much this is personality (I happen to have a knack for logical/abstract reasoning and I happened to learn to read when I was very young) and how much is an effect of reading. After all, anthropologists are great at the concrete rather than abstract, but maybe they get lots of training in it. I've also heard the Japanese are better at it.
TFA clearly postulates it has more to do with the kind of vocabulary, or maybe it's on an increasing scale with more language.
