There is a lot of rubbish written about the lateralization of brain function. The book you're reading appears to be infected by some of it. Easy to use antidote here.

You mentioned three books in the six posts you made so far, and all of them are a bit on the nose in one way or another. If they were recommended by some individual or school, I suggest you steer clear of them in future and find help from someone with a more rigorously scientific approach to the issues you're trying to learn about.
