Mottron, Dawson and associates' paper out since last year......

..... and I've only just found out. Have you read this? Covers autism Asperger syndrome, sensory perception, savantism, synaesthesia, hyperlexia, perfect pitch, all the interesting stuff. Sadly most of the paper is in technical language that I can scarcely comprehend, but that isn't too much of a deterrent to a housewife know-it-all. "Plausibly, these apparently different phenomena develop through a veridical mapping mechanism whereby perceptual information is coupled with homological data drawn from within or across isomorphic structures." Ay? 

The argument that there is a link between autism/Asperger syndrome and synaesthesia is sure to jar some rings in the synaesthesia community, which is gratifying, but the citing of journal papers about Daniel Tammet as a case study, and the description of him as a case of co-occurring autism and synaesthesia is quite disappointing.
