Have you given him the Meyers-Briggs personality inventory for kids? I mean, some of what you're describing sounds like a more extreme version of my whole household of INTJs. (With the exception of my 4yo extrovert, of course...) Here's the link, if it helps:
http://www.personalitypage.com/cgi-local/build_pqk.cgiActually, the anger usually results in frustration because: he doesn't want to try, he thinks he isn't good at something, something is harder than he expected, someone is doing something better than he is doing it.
Well, frustration at not doing things perfectly and the best of all people in particular is VERY often true of HG+ kids. My DS7 has a very calm demeanor...most of the time. Then he loses at something and he throws a tantrum.
Also, I know that 7yos (and kids in that age range) can be *extremely* competitive in game situations, especially HG+ ones. Case in point: I taught a class on the Vikings/Norse to GT kids in 1-3rd grades, and we played a couple of games. Both times kids nearly came to blows over the games--different kids each time!--even though I was standing right there monitoring things! It was bad enough that I'm considering dropping games from my course completely the next time I teach it. (And BTW, I had an AS kid in the class, but he wasn't one of the kids involved in the conflicts.)
I know I sound like I'm saying your son isn't AS, and that's not really what I'm trying to do. I know almost nothing about AS! Just the little I've picked up here and there. But I guess I could see plenty of other explanations for the things you are describing.
I think your son's inappropriate emotional responses are the ones that most concern me. But as someone who is not AS and who often doesn't "get" the emotions of other people because of my particular personality profile (We INTJs on the Meyers-Briggs are Spock-like, if that tells you how clueless I tend to be about emotional stuff...), the other behavior is certainly problematic in terms of daily life, but it seems to my utterly uneducated-in-AS mind to be not all that abnormal. Just more extreme. But again, maybe we're bordering the spectrum and just don't know it...
One other thought: have you tried keeping a behavior journal for him? I've heard that sometimes you can spot triggers (lack of sleep, food allergies, sensitivities to food dyes or pesticides, etc.) that cause/contribute to troublesome behaviors, and I'm thinking that there may be something like that going on, maybe? (I'm also pretty clueless about this stuff, but it's another potential avenue to explore.)
But of course, feel free to disregard anything I say here! I am totally talking out of my area of expertise, such as that is...
