Here's the minimum amount of categories I'd have used in a poll like this:
Sensory/perceptual.
Cognitive.
Movement.
Executive function. (Might just do a single movement/EF category, might not. I am not comfortable with the EF concept but don't know a better term. It's just poorly defined buzzwords make me uncomfortable.)
Emotional.
Social.
Communication.
Possibly some kind of category dealing specifically with things like compulsions, which don't comfortably fit any other category and have serious effects on many autistic people.
Autistic people's differences seem to me to be divided into perception, thinking, and action, as well as the interactions between the three. This is of course an arbitrary division and one area of difference can affect all three at the same time.
Donna Williams divides autistic people's difficulties into problems of connection, problems of tolerance, and problems of control. All of which van affect perceptions, thoughts, and responses to the world.
Either way, it's hard to know where to draw dividing lines, especially for people like me who can see how artificial and distorting categories can be (which is part of why I have trouble summarizing and shortening my writing).
I think if I was going to explain my own autistic traits to someone else, I'd go for something like...
1. A description of the way I perceive the world around me, and how I do and don't handle thought, etc.
2. I'd probably steal as usual that wonderful little chart describing movement issues affecting perception, movement, complex actions, thoughts, language, feelings, and memories.
3. Effects of growing up without as many of the normal experiences that shape nonautistic people's lives, and of having developmental stages that are scrambled, delayed, skipped, etc. compared to nonautistic people's stages.
Anyway, most of these ways of dividing up autism are pretty artificial. Like, the same single issue can cause problems in communication, socialization, emotions, movement, thinking, and perception. So dividing it up this way is mostly about effects, not causes. But talking about causes is messy and difficult in other ways.
