The term high functioning doesn't mean when compared to the rest of society.
It's not comparing toddlers with adults.
It's not comparing disabled ten year olds with non disabled ten year olds.
It's comparing a person, in the case of this thread a ten year old boy with X condition, with other ten year old boys with X (the same) condition. Some will be deemed high functioning and some won't.
Yes, thank you, this is a fantastic way of explaining the comparison of needs. Very eloquently put.
The more I think about functioning labels, the more they confuse me. Oftentimes I'm against functioning labels and then the more I think about the alternatives it really divides me. I disagree with the American model of giving autism levels too because in my childhood and teens you would have classed me as a level 1 autistic or high functioning autistic and now I require significant support to manage my calendar, significant support to manage my medication, significant support to clean, iron, fold, put away, and wear the right clothes, significant support in public to avoid changes to plans and routines or overwhelming environments, significant support with hygeine, but the thing is I can talk, I am hyperverbal and I have the right kind of support so I often look put together, and not at all disabled.
Compared to my cousin who has never talked a day in their life, but can manage their daily living activities pretty independently, copes with changes a lot better than I do, has more traditional obsessions and collections and hyperfocuses, requires support only when speaking is to be expected as they suffer massively with social anxiety around people's misconception that because he can't speak he can't understand what is going on, and he visibly stims more, but he's a right book buff. He loves learning and probably has a whole library of knowledge in his brain.
So you can have autism, without learning disabilities and still be medium or high support needs. Support needs labels are more effective at giving insight to a person's needs. Needs labels don't indicate developmental function though and this is what divides me the more I think about it.
My own little boy is non-verbal but thrives in chaos, has no social anxiety, doesn't visibly stim, makes noises like he's talking such as delayed echolalia and for his peer group actually uses those phrases to roleplay and maintain friendships, has some struggles with transitioning and changes but although his reactions can be intense they're very short lived. Many people that have met us don't even know that we're both autistic. They just see a happy zoomy playful little boy and a really shy mum, but we both have to have quite a lot of daily support especially compared to my non-verbal autistic cousin who is visibly autistic to those who see him.
I have however said myself before that the difference between people with autism that are "high" or "low" functioning is that low functioning people have learning disabilities, and I have changed my position on it as I believe I was wrong. Higher support needs people may have a higher comorbidity rate with learning disabilities especially if they've been high needs since birth, but it isn't necessarily factual. Again, it's another reason why I am so divided on the functioning labels.
I can also see the side of parents with autistic or disabled children who have significant impairments and disabilties preferring functioning labels because their children are high support needs but they're either unlikely to progress developmentally at a rate that will eventually allow them to catch up to their peers, or they've received no support post-diagnosis to better their children's outcomes or even with interventions and therapies, there has noy been or will not be any improvement in functioning and their care needs will either remain the same or need to be increased.
So where as I once felt like I was pretty solidly against high and low functioning, I've actually found myself feeling a bit shaky, and even describing myself to others as medium to high functioning with medium support needs, and my son high functioning with high support needs. I don't think there is or ever will be a perfect way to describe in a simplified way how each persons autism affects them.
