Discussions of this nature are especially interesting to me for
personal reasons.
I was born premature. No useful vision in right eye, very poor
vision in left eye. Left ear is "tin ear", right ear only goes
up to 5000 hz. Diagnosed with cerebral palsy early on.
Yet, you'd never know it. I have perfect pitch and can 'hear"
octaves far higher than my ears have EVER been capable of
hearing. [hearing test at 4 yrs old caps my hearing at 5000 hz,
as has every test since then, and I'm 43 year old now).
Glasses correct my vision to be good enough and I see in cyclops
vision instead of overlapping images. [they're side-by-side
making an entire field of vision].
So, I judge nearness by size comparison rather than some special
kind of "popping out" special effect, which I've never had.
So the nature of processing within my own self has been
fascinating from the time I was young. It's also what gave me a
great affinity to computers early on; I could relate to parts
going bad as I had some that were different than other people's.
Yet, I never felt handicapped or incapable. nor is it
noticeable. I credit early physical/occupational therapy between
the ages of 3-5 years old, allowing me to enter regular school
and obviously, I must have a 'mild case' - if I indeed have it
at all [no way to know without a brain scan]; but if nothing
else, the "input" issue... as well as output issue (corrected
stutter when I was 8 - I'm FULLY CONSCIOUS of every part of
every word when I speak to avoid going "um" or stuttering)...
has given me a strong introspective notion of the "inner
computing mechanisms" going on as it relates to my systems as a
whole.
