With all due respect, I must disagree. It depends on the level of disconnectedness. Some autistics are as disconnected as someone with schizophrenia. (This is why in the past, many with austism where labeled as schizophrenic).
You cannot beat or cajole or teach or manipulate or use any amount of behaviour modification on someone who is severely disconnected.
When I was young, I was severally disconnected. Attempts to discipline me did end up in the discipliner getting very angry and I was abused on many occasions.
I was very capable of being "good," if I had not been forced into situations I did not understand where people demanded WAY more of me than I was capable.
The trouble arises when NO ONE can assess how capable we are, but THE PERSON WITH AUTISM -----and we are routinely not trusted.
If I say I am overwhelmed and cannot make the bed right now, the smirk sets in, the attitude the OP displayed in all its unsettling glory. He KNOWS the kid is capable and so do half the posters....because THEY WERE.
Well I was not, and I defend the little ones who cannot see it, are not being "bad," are totally overwhelmed just having to get out of bed and face music and sounds and cold and heat and people demanding and food that hurts to eat and pain and smells and people touching them......all within the first 15 minutes of the day!!
And not even knowing others are not feeling this horror till many, long, horrible years have past, filled with abuse, demands, cruelty, hits, eye rolls, backs of the hands, slaps to the face, bullying, teasing, misunderstanding, social isolation, abuse in various forms.........
No wonder one of the major causes of death with those with autism is suicide.
I agree with
@rollerskate . If home is not the safe place, well, no where else is going to be a kind and gentle place for an autistic.
