The discussion here about differences in our sensory experiences is eye-opening and fascinating.
I was diagnosed as “Asperger syndrome / high-functioning autistic” at the age of 33, almost 10 years ago now. During that time I’ve been advised several times not to reveal that fact to anyone, so this is the first time I’ve written about it in a public forum. You’re all just that welcoming.
For me, sensory overload seems to be the basic cause of most of my divergences from the norm, with several dozen coping mechanisms and work-arounds layered on top to confuse things. I liken it to going through life with everything seeming to be a little brighter, louder, smellier, and just generally more intense than it is for neurotypical people. That applies to internal sensations and emotions as well. It leads to ADHD-like symptoms where it can be difficult to ignore seemingly trivial things in situations with multiple stimuli, i.e. getting distracted by a bug or a bird while talking to someone. It leads to avoidance of loud crowds, parties, and other high-stimulus events, which in turn leads to falling behind in social skills through simple lack of practice. It leads to sustained focus on subjects of interest which would be border-line boring to neurotypical people, but generate just the right level of fascinating details and rewarding puzzles for me. For the past couple of years one of my “special interests” has been identifying spiders on iNaturalist, but I’ve had several others over the course of my life, some of which I return to from time to time.
A very simple model (maybe simplistic), is that every person has a certain amount of incoming information, and a certain level of processing power with which to analyze it. People with severe autism are getting bombarded by more information each second than they can process in one second, so things get missed and lost, seemingly ignored, and there’s no processing power left over for anything else. People on the high-functioning end, like me, have enough processing power to deal with most day-to-day situations, but have trouble in some high-intensity situations, and spend a greater fraction of their processing power on living in the moment. That can lead to a deficit in long-term planning, just from having less left-over processing power to do it with, but can also make it easier to maintain focus and attention in low-intensity situations.
Anyway, I’ve accumulated a lot of thoughts about autism over the years, and it’s really tempting to do even more of an info-dump here, but I’ve at least learned to recognize when I might be going too far and to restrain myself a bit. Thank you, everyone who shared their own issues, and thank you, everyone who has expressed interest without judgement.
