Human vision is "foveated". This means we only have high visual acuity in a tiny portion of our field of view, with really crappy acuity just a few degrees off of our line of sight. The reason we don't perceive the world as fuzzy in the periphery is that we constantly scan our "pencil of acuity" over the scene and build up a mental image with the data acquired during scanning. Everybody's vision works this way, neurotypical or not.
I feel like my thinking is similarly "foveated", in that I tend to focus on one thing at a time, really grokking that thing, but failing to notice anything else. Does anybody else feel that way?
