No great surprises there, although it was a little unexpected that some of the prodigies had such low IQ scores.  
I'd be interested to learn more about what differentiates non-Asperger prodigies from HG+ non-prodigies with similar gifts in working memory.  Domains with a real-time performance component, such as music performance, would obviously benefit from additional gifts in processing speed.  I wonder how much our areas of interest are informed by relative difficulties or advantages in certain areas, which we don't tend to notice consciously.  Thanks for posting.
