YES! YES! YES! I do this all the time when others are talking! I am not hard of hearing, although it has declined a little from being exposed to loud, blaring music at major family functions a number of times years ago. I had to drive my mother to these functions as she no longer drove. She passed away 8 1/2 years ago, so now I no longer have to go to these loud events. However, I can still hear well enough, but even before I lost a little of my hearing, I did this--for my entire life. I am better able to process what I hear when I can see people speaking. I am definitely a more visual type person where input is concerned. I can usually handle phone conversations okay, but I am able to focus more on the sound then, as there are usually fewer distractions then.
I think we on the spectrum have a number of processing issues. some are more physical-medical, and some appear to be psychological. However, I think at least some of the psychological ones are neurological in basis, so that comes back to a physical-medical cause.
I know that there are researchers looking into the causes of spectrum conditions, and some progress has been made, but it really doesn't help fix anything. I hope that eventually changes, but for us older ones, simply fixing the causes won't leave us knowing how, and able, to function in the NT world. Still, I hope help does come for my younger spectrum mates.
Remember, we on the spectrum are all:
A Different Drummer
If a man does not keep pace with his companions,
Perhaps it is because he hears a different drummer.
Let him step to the music which he hears,
However measured or far away.
--Henry David Thoreau
