Yes, I think visualization provides the key benefit. When I read something good, my imagination recreates the sights, sounds, smells, and experiences in great detail and tunes out the real world. I lose all awareness of the book's text and everything around me. It's like I "live in the story." This mental state can persist for hours, even in loud environments with high levels of activity around me. After I sleep following some deep reading, I notice a heightened ability to visualize a problem and run mental simulations of potential solutions. It's like I "live in the problem." Interestingly, when I have played video games with similarly high levels of focus, I have not realized work improvement afterwards. In fact, video games seem to degrade my work performance. I think that is because video games generate stress and do not stimulate nearly the same level of mental world-building that good fiction does.
