My son ,9,was just diagnosed with Autism. All my kids draw very well,better than most of their peers(but not as well as yours,wow!)
My husband and I met in art school. All my family(myself,parents,brother,husband) we're all visual thinkers. Up until recently I thought that was the norm.
Besides telling you how impressed I am with your son's drawings and hope he's still practicing art,I was just wondering to myself,if artists have a greater chance of having children with Autism or even having undiagnosed Autism themselves.
I have Temple Grandin's movie about her life, and have read several of her books. She has been able to express the world of some autistic children and adults. It was like a revelation to begin to understand that everyone does not see the world the same; that for some, the world as we live it is a jumble of confusion.
The story you tell of Max is as enlightening; and not all autism is of the same degree. Those pictures by the way, are far better than I have ever been able to produce. To have learned and established the language of pictures must have been, maybe still is, very difficult for your family.
We are not taught that language, the emphasis is on what the meaning of is, is.
What pictures do we use for so much of our usual communications? For the sentence I just wrote? Two remarkable stories here.
