In terms of auditory reading, it's laborious for me to "sound out" an entire sentence in my mind. When I'm reading as fast as I can without speed-reading, what I'm "hearing" tends to be the most relevant terms in any given sentence.

1. is familiar to me in a lot of ways; I experience something similar when I'm typing, which I call "thinking with my hands." It feels intuitive to imagine that my fingers know what to say, and that my mind is largely apart from that process. (It bothers me that this is intuitive, much like how it bothers me that it's intuitive to think of tension as glow-ey light that flows through one as one breathes in and out, but whatever.) The difference between hand-writing and typing is like the difference between reading back when I needed to sound out words, and what it's like now that I can speed-read and entirely eliminate subvocalizations.

Thinking-with-bodies in general is useful to me. I've found I can remember the entire content of a lecture by looking at a doodle I've done whilst listening to it, even if the lecture in question was years ago. I really, really enjoy the method of loci, and imagine several houses and a garden to keep ideas in order.
