I am an NT diagnosed with ADD in middle school, and having personality traits commonly found in autistic-spectrum people (my father said I was really Spock's daughter and not his, but appropriately, that would make me 3/4ths Human), and who has a friend with AS from whom I heard about this place. I actually kind of envy autism-spectrum people - most of the high-functioning autism/AS folks I hear about sound smarter than I am, and they have very unique and independent minds and very intense focus. I can have intense focus intermittently, but I don't feel like I ever obtain much expertise on anything, and wish I could re-spark some more passion for the stuff I'm studying in school (but I wouldn't be surprised if Aspies also have motivation problems)
My user name is a tribute to my essential non-autisticness. See, I was reading Temple Grandin's Animals in Translation, and was looking at the bathroom wallpaper at my grandparents' vacation home, and started seeing angry ghosts and puppy dogs in the vine pattern. Then, I noticed another section of wallpaper in which I wasn't seeing the same angry ghosts and puppy dogs, although I could see other ghosts in it. I pondered and puzzled, and protested that the wallpaper looked the SAME everywhere! Eventually, after maybe 20 minutes or some other inordinately long time, I finally got the idea of comparing a specific feature, the bunches of grapes, between the "normal" and "freak" sections of wallpaper, and I discovered that the "freak" section was upside down. From what I'd just read about autism - at least the HFA variety that Temple Grandin has - my experience was NT squared: hallucinating/filling in vague holistic patterns that aren't there, and being painfully slow to notice the essential details. Were I on the autistic spectrum (or HFA at least), none of that probably would have happened. Temple's right: we NTs are in our own little world. Can't see the trees for the forest. Other non-autistic traits include a lack of sensory oversensitivities and scramblings, lack of a need for rituals and sameness (although I may do many routine things out of convenience), and a much smaller than average head.
I find the subject of cognitive and perceptual variation among people and its implications to be a fascinating one. I might share more thoughts I've had about cognition and perception and the like at other times. I'm always up for some interesting note-trading. I enjoy talking about myself, something I probably have in common with a lot of you folks.
