Although most of this discussion isn't/doesn't "click" for me......too many "vague" subjects, i.e. not "concrete" or factual (?) enough for me, and would probably end up resulting in me analyzing this discussion for many moons.........it does prompt me to comment on a few things:
This makes social interaction a conscious activity, as opposed to an unconscious one. Instead of speaking and acting naturally, you must think and then act. Should I look you in the eyes, should I speak, should I laugh? These are questions I guess you seldom consider consciously.
Yep........this is EXACTLY my experience.....always.
I think the computer metaphor works here too. The brain is a massively parallell computer. At any given time, lots of signals are going from lots of synapses to lots of other synapses. The part that takes the most energy is the conscious part. NTs keep a background process for social behavior. It's always in the semi-conscious area of the brain, and does most of the social processing. This is where the autistic brain diverges: the background process does a lot less, and so the conscious part must do much more. This does give a certain kind of power, in that you get to exercise a lot more control over your social actions, because you do them consciously. That's the good news. The bad news is that it's not optional. You have to do it consciously, because if you don't, you won't function at all.
Yep......I use the computer "analogy" when describing my brain/mind often. I like and use analogies often; although, I don't get metaphors most of the time (even my 17 year old son has commented to me because I obviously didn't "get it" somehow or it didn't compute in my mind, "Mom, that's a metaphor. Don't you know what a metaphor is?" Well, I had to say "I guess not!") I can sort of understand intellectually what it is and means, and MIGHT recognize one once in a while, strictly because I keep looking up the meaning of the word "metaphor" in the dictionary; but as a rule, metaphors escape me unless I stop to extremely analyze what someone is saying to me, and oftentimes in social interactions, I don't have that kind of time to do that. Over the years, I have strictly "memorized" specific often-used metaphors, though, so I can recognize some during social interactions with NTs.
I do however have a gift for turning literal meanings into humor, if I do say so myself, but in this case it's entirely optional.
Ok, I learned to do that, too. Mainly to "cover" for my social, language and communication inadequacies. If I don't understand something, usually as a result of my extreme literal interpretations (which I found out about after many years of being told I do that), I find a way to look at the communication I am in the middle of in a humorous manner........I think I do this mainly by picking out "words" within the conversation that I did understand and doing "wordplay", as I call it, with those words. Hard to explain. And normally, the way in which I do that is to orally mention how/what that word conjures up "visually" in my mind. NTs seem to think that is hilarious. Laughter is contagious, as they say. Even for auties, I believe.
And who was it who mentioned something about all of this being exhausting (can't find it right now).............I do want to mention that I tried (again) to explain that to a couple of my NT acquaintances just this week! Somehow, I am unable to make myself understood, I guess, about how exhausting it really and truly is! I watched as an NT acquaintance of mine looked off into the distance (her eyes sort of went upward) when she was attempting to understand, I guess. She said she just didn't understand that, though. Why something this "simple" would be so exhausting. I have explained many times how MUCH of what I say and do (even everyday body movements, etc.) are conscious thoughts, not "automatic". It took many years of practice and study, too.
