I looked online for some articles on autism, specifically autistic savants, and I found this so far.

Going along with what I asked in class regarding whether or not autistic people are not tricked by illusions, because they only see specific details of what they are observing instead of interpreting the whole and jumping to a conclusion. The article states:
"Autistic children differ from non-autistic children in another way. Normal kids find it frustrating to copy a picture containing a visual illusion, such as M. C. Escher's drawing in which water flows uphill. Autistic children don't. That fits with Snyder's idea that they're recording what they see without interpretation and reproducing it with ease in their own drawings. "
The article goes on to talk about the difference in perception and how it can stimulate the brain in a different way and can help you see it in a whole new light. The example was how some art students are taught how to draw using a mirror or drawing the negative space of an object instead of the object.
