I found this from 1983 of 26 autistic children: https://www.ncbi.nlm.nih.gov/pubmed/6580656
Quote:
Sixty-two percent of the autistic children were non-right-handed compared with 37% of the controls. Left-handedness in autism was associated with an abundance of delayed echolalia. Heredity for left-handedness in some cases, and assumed brain damage and immature patterns of lateralization in others, were considered the cause of non-right-handedness in the autistic children.
There's no left-handedness in my family at all, as far as I know. Maybe there were some lefties that were forced to switch, but I never heard about them. I was right handed right from the beginning, I believe, and thought left-handedness was against the law or something, based on how people reacted when I wanted to experiment with using my left hand. However, I taught myself to be ambidextrous when I was about 8.
