Variance

IMO, there is sufficient evidence from diverse cultures to lend additional support to a basically neurological basis for the attributes observed on the spectrum. However, I still have a lot of questions.

As a sociologist, I have become interested in exploring possible social structural or cultural contributory factors, but I have not seen much in the literature on that subject. Most of the pre-1980s stuff on autism, etc. is psychodynamic and Freudian.

I also don’t know if Emil Kraepelin’s recent resurrection in the DSM-III, DSM-III-TR, DSM-IV, and DSM-IV-TR explains all the variance either.
