Try searching for Atwood or Grandin. I don't know what kind of research sociology entails. Also, just try searching "Asperger*" (asterisk isn't a typo) as a keyword into your school library's search engine. Try under articles, or books, or both. It's better to start simple, I think. Try neurodevelopment or neuro deveolopment or neurological development. There are a lot of co-morbids with AS and you might want to look into those, too, OCD, Torette's, ADHD, and the like. Again, neuro development. Hope this helps!
