Eye contact is an area for development in many individuals with social skills vulnerabilities, including the majority of such, who are not on the autistic spectrum.
Interesting statement that I'd like to hear more about. My DD has poor eye contact which I notice in these situations:
1) With us when emotions are running high (not an issue when things are positive or neutral)
2) With adults in authority or adults she does not know well. This can be VERY noticable.
I never see it with other children--ever. I have also seen the "referencing" behavior discussed, but only with parents.
