I've never thought of researching this as a sensory issue, just figured I had lousy depth perception-although my opthamalogist tells me my vision is now corrected. They did do a test to see how well I perceived points of light at increasing distance from the center of my visual field, to determine my range of visual field. Interesting result. I have a complete field of vision-but not on the first pass. I have to "learn" how to find the area being stimulated quickly enough to report with confidence that i saw it. There's a time lag. A small one-but enough to be dangerous. I do not drive.
Actually, there's more than one reason I don't drive, and they may be relevant to what you're talking about. Number one, I get lost. Not on foot or on a bike, or almost never. And even when I do I don't panic. But in a car-too fast, too much stimulation...turns out I was never really paying attention when I was riding by in a car...or maybe I can't, not on the highway. I used to think I just had lousy spatial relations skills-after all, I failed college algebra. Then my brother reminded me I probably failed college algebra because one: my instructor didn't speak english two: I didn't go to class three: one reason I was missing class was I was meeting with the cops and getting medical tests and treatment after being raped at the beginning of that semester. So. Scratch
college algebra as an evidentiary link. After all, I did fine in algebra, geometry, algebra II, and trig in high school. Did great with the math in chemistry in physics-I love math with an actual point.
So maybe it's a combination of factors. It's the sensory thing-as in too much stimulation. It's the fact that I, at least, seem to find processing unpredictable visual stimuli somewhat difficult. Finding the edges of things and such...I don't think these are depth perception so much as boundary perception issues. Sometimes it's hard to focus because there are too many edges...am I making sense?
