One of my inspirations in my research on the minds of people with Autism is Temple Grandin. She has a couple of books published, one is called "Thinking in Pictures." As an adult with Autism, she writes about how her mind works and how others with Autism think. There was recently an HBO movie made about her, starring Claire Danes (which I hope to watch over break, if my kids will nap at the same time for me). I found this video clip of her speaking at a TED function via The Art Teacher's Guide to the Internet. The video is a little long-20 minutes, but will give you a sample of what she talks about in her book, and I assume her movie. If you're interested in how children on the Autism Spectrum think it's a good place to start.
