I think you're right. There seems to be two sorts of attention in the mind, narrowly focused attention and broad diffuse attention. I see the goal of meditation not so much as alternating between the two modes but rather like balancing them and running them both in parallel. This entire video is really excellent, but see particularly this bit here, where Iain McGilchrist describes the concept. [this video]

That question has a very complex and complicated answer, hence why McGilchrist devoted the entire first half of the book to it, I can hardly summarize it here. You might want to watch the RSA Animated talk by McGilchrist: [this video] If this reminds you of Julian Jaynes, then yes, there exists some similarity, but, to quote Wikipedia: "McGilchrist, while accepting Jayne's intention, felt that Jayne's hypothesis was "the precise inverse of what happened" and that rather than a shift from bicameralism there evolved a separation of the hemispheres." In my opinion, it seems like a better question to ask then consists of asking if what McGilchrist describes holds 'all the way down', and I lack an ans

On one such test she had no difficulty giving the correct meaning of sentences containing familiar homophones, demonstrating that her receptive comprehension was significantly better than her expressive language. Genie also did very well at identifying rhymes, both tasks that adult split-brain and left hemisphere

>(The old: left hemisphere math, right art or vice versa has been debunked if I remember correctly) As usual with biology, it's a bit more complicated than the '60s explanation ever revealed to the public. [this video]
