"My hypothesis is that savants have privileged access to lower level, less-processed information, before it is packaged into holistic concepts and meaningful labels. Due to a failure in top-down inhibition, they can tap into information that exists in all of our brains, but is normally beyond conscious awareness."
It's a high tech version of "Drawing with the Right Side of the Brain".
It's an interesting idea - especially given the neurological literature about acquired (i.e. due to stroke or other neurologic disease) savant or high artistic ability and the neurological findings in individuals with autism. Snyder's theory may also have implications for our understanding of twice-exceptional individuals (gifted with LDs), creative dyslexics, gifted children and adults with overexcitabilities / sensory processing, and the co-occurrence of high creativity and mental illness.
