I don't mean to offend anyone but I think it depends on the child, their age etc and I do not mean to undermine anyone else's experience by sharing mine.
'Normalising' is not the same as 'treating' Dudes. Yes, obviously you treat someone with a medical problem with drugs.
But we are talking about behaviour and a neurological difference. I completely understand and accept that there are children whose communication skills or behavioural stims etc create an extreme barrier to their daily function and so stop them achieving their potential.
I wholly accept the great gains that can be made with ABA for children, particularly, young children who can be taught and can learn skills which seemed wholly impossible without such intervention.
I wholly accept that. I really do.
However, for a ten year old, able Aspie who is able to communicate how he feels and why things are difficult to him, I found the model very 'normalising'.
So, for example, when being in the classroom was extremely difficult for him, and he wanted to sit outside but a little out of sight of the group, he had a consultant (ex Tree House) tell him he was being 'controlling' and that he had to do what his teacher said. This consultant said 'anxiety' was just a word and they did not use such judgments but he was equally happy to talk of DS as 'tantrumming' or being 'non-compliant' which are value laden.
He had no strategy to deal with this and spent no time talking to DS about what was happening. His drive was - what did the teachers want to happen and that is what DS must do. If he didn't like it, he was 'tantrumming' or being controlling and this needed to be stamped out.
I can't tell you how damaging to a highly anxious child this approach is as it takes no account of the emotional or cognitive side of a child's development.
It just seemed too easy to gloss over the reasons for the problems by forcing behavioural change irrespective of the consequences. But why? Compliance isn't an end in itself, it is a state of being which allows other things to happen, e.g. learning. But if a child can't learn because he can't cope with school (and some can't) forcing compliance leads straight to one type of change in behaviour - school refusal.
There are other ways to skin a cat.
This is the second ABA consultant I have used and both have been very similar and unable to vary an approach which may be effective on a young child with one for an older one.
This may not be your experience but it was mine.
