It would be nice to see a more extensive study of the score distributions for this kind of test. My hypothesis is that the score distribution for NT's will be more clustered around a specific value whereas the AS scores will be more widely distributed. In other words someone with AS is more statistically more likely to score very low but a large number also score normal or above normal.
I think you're correct! AS/HFA may not all score the same. I found a peer-review journal article from Simon Baron-Cohen's website. It listed the standard deviations for both the AS/HFA and the control groups, and the AS/HFA group has more deviation on the eye test. One thing I found interesting, the standard deviations for the Autism Quotient test is about the same in all the groups, but the SD for the Eyes Test is greater in the AS/HFA group.
Because of my curiosity, I went to
http://autismresearchcentre.com/tests/e ... _adult.asp , clicked "The 'Reading the mind in the eyes' test revised version: A study with normal adults, and adults with Asperger Syndrome or High-Functioning autism" and found a distribution on page 245.
If you're interested more about those on the spectrum recognizing emotional states, there are more downloadable peer review studies on that webpage.
