What We See When We Read

To be honest I think I read entire books without even considering what colour a person's hair is, how tall they are, what shape their nose is.

key passage:
"The debate was resolved by Francis Galton, a fascinating man who among other achievements invented eugenics, the "wisdom of crowds", and standard deviation. Galton gave people some very detailed surveys, and found that some people did have mental imagery and others didn't. The ones who did had simply assumed everyone did, and the ones who didn't had simply assumed everyone didn't, to the point of coming up with absurd justifications for why they were lying or misunderstanding the question. There was a wide spectrum of imaging ability, from about five percent of people with perfect eidetic imagery to three percent of people completely unable to form mental images."
I don't have strong mental imagery, and it's actually a problem for me when reading some fiction... Some authors love putting in long, detailed, descriptions of characters.
That's incredibly boring to me, and I just skip those pages.
I've found that people with very strong visual imagery love anagrams, because they can actually visualize and rotate the letters. And to me, that's basically a super power.
I suspect that if verbal descriptions of faces were a constant part of society, that our ability to imagine faces based on authors' descriptions (using that shared vocabulary) would be much better. I also wonder what experience police sketch artists, like the one who drew Anna Karenina, have when reading books, as they probably think about this sort of thing much more frequently.
As a sidenote, it may seem like I'm appealing to the now somewhat discredited Sapir-Whorf hypothesis, but I'm only saying that our lack of vocabulary constrains what we express, not that it constrains our cognition.
Personally, when I read I do visualize things, but I don't have strong visualizations for people's faces, much like mcjiggerlog elsewhere commented.
I do have a very general idea of what main characters looks like, in particular about whether they are young, middle-aged or old, and about their hair color. When I see a movie adaptation, this always clashes with my preconceived idea. "No, no, the character was older and had black hair!"
I'd attempted to read The Fellowship of the Ring a few times as a kid, but never got into it. I watched the movie before I started it in earnest, and I feel I was kind of cheated by all of the visuals I wasn't able to conjure up myself. For that reason, some of my favourite parts of the book were those that were cut from the movie, such as Tom Bombadil and the Barrow-downs.
Thankfully, I went on to read The Two Towers and The Return of the King well before the movies were released, and enjoyed them much more because I got to inject a lot more of my imagination into them.
From a writer's point of view, maybe it is fun to put a lot of details about the world they are trying to describe in a very detailed way.
