Hmmm....maybe I'm a left-hander in disguise! By these definitions, I definitely seem to "act" like a left-hander.

The correlation is certainly possible if it turns out the preemie birth - Asperger's link turns out to be true; a lot of premature babies are left handed (myself included) because the right side of the brain apparently develops faster than the left before birth (or so says my ex-nurse mother) meaning that the right hemisphere, which controls the left side of the body, is more functional at birth.

I also found this quote from a magazine/journal article on the subject: "Extremely premature babies weighing a pound or less at birth -- whose survival is becoming increasingly common -- have been found to have at least one quirk that will remain with them all of their lives: At least one study found they were left-handed more than half the time."

No, righty here. One of my brothers is lefty and NT, the other is righty and NT. No correlation.

I am a right-handed aspie. In my class there's a left-handed kid and he surely doesn't have AS. However, I don't think there's a connection between being left-handed and being an aspie.

I am mostly right-handed. I write with my right hand (always have done) and I cannot write with my left hand at all, even if I tried. The only thing I do with any hand is use a spoon or fork. But I use either hand subconsciously, so I don't know what hand I use more. But I don't relate silly little things like that with being on the spectrum, I just think it's just a me thing.

I have a diagnosis appointment in 2 weeks and one of the screening questions is "Are you left-handed". Make of that what you will.

I also work in an environment comprising 32 engineers, 13 of whom are left-handed. The more astute of you may see that this is way above the norm for left-handedness. As is the engineering/Asperger link.

Once a cop told that when he went through an exam, the examiners have asked if they are left handed because they thought left handers are more clever and analytical. But I didn't understand if this was his interpretation (he was right handed) or they actually thought that. It sounds biased to me.

Don't see how there could be a correlation. Both myself who is right-handed and my daughters who are both left-handed have AS.

Both my children are left-handed and both were born bang on their due dates.

As in my previous post, both my daughters are left-handed, and both are very emotional, the younger has emotional dysregulation so is highly emotional (she has always burst into tears at "sad music" since being really tiny for instance). Emotional dysregulation is a feature of AS, and though being right-handed I have it too. I really don't see the correlation about left-handedness.

Well, I do think that left handers brain might be a bit different because the right hemisphere controls the left side of your body and the left hemisphere, the right side and they have different functions so brain might be considered as a muscle that is active more in the left or in the right. The thickness and the lenght of corpus callosum is important as well. If there's any particularity, it is not determined only by the hand preference, but you can't ignore this factor either.

I've actually researched this:

This study indicates that autistic people may be less likely to be right-handed:

Quote:
The present study reports preliminary data from two unselected samples of carefully diagnosed autistic subjects (children and adults) and an assessment procedure that includes a large sample of items, appropriate for lowerfunctioning autistic subjects, with multiple presentations within and between sessions 1 week apart. The study seeks to determine (1) whether a raised incidence of non-right-handedness exists in these samples (2) if so, what constructs best represent this shift in the handedness distribution (i.e., phenotype and CNS substrate) and (3) whether these handedness phenotypes are associated with different levels of cognitive functioning. The results reveal a dramatic shift away from right-handedness in both autistic samples, due to a raised incidence of two phenotypes, manifest left-handedness and ambiguous handedness. The ambiguously handed, who were postulated to represent substantial bilateral CNS pathology due to early brain injury, were found to have much lower intellectual scores in one of the study samples.

Ah thanks for this. I wonder if this is also the reason for why I never crawled. My lower IQ is probably also due to brain injury I had when I was 3. I wonder if autistic can juggle?
