Oh I have heard about this. I have never seen reports of it in such clarity and it is sickening, but very sadly, it is still happening today.
There is a place in New England (the school is in Rhode Island and the residential homes are in MA) that does this still. It is called now the Judge Rottenburg (not sure of the last name) center. It used to be called BRI or behavior research institute. It was started by Matthew Israel who also worked with Lovaas in these first studies in the posted article. Enough to make one sick isn't it. Gets worse.
It is now name the Judge whatever center after the judge who ruled it should be allowed to stay open. Before my kids were born I was early in my teaching career and I wanted to work with special needs children, particularly severe special needs and autism. I called on an add in the newspaper and went for an interview at this place called BRI. I had NO idea what it was when I went. Needless to say when they called me back I declined stating I could not work in a place like that.
I ended up working in a different residential school. In hindsight though the place I went was much more humane, thier practices still make me quite uncomfortable now that I know more. HOwever, my husband also worked at this residential school where I worked. He had a coworker on his team that had worked briefly at BRI and the stories he told were horrific.
How that can even be remotely close to legal to do to a human being is beyond my imagination. But it does still happen. As parents we really have to be vigilant and part of that is knowing what is out there.
