I am not a Doctor but I play one on the Internet and he is definitely an Aspergers kid. I have a 19 year old with Aspergers and see a lot of my son him. My son does not stem like Ian does. Stemming is his coping tool to keep in control, so that is when you will see repetitive behavior such as rocking and in his case always moving. Most Aspies are very smart and have a focus that they excel at. My son is into Acting. He can pretty much mimic any actor and memorizes lines quickly and with little effort. Aspies are socially awkward and have a difficult time mixing in with the norm. They usually cannot and do not make eye contact. The fascinating thing is that Aspergers kids are socially awkward. This is such of an accomplishment for Ian to be in that house, but I believe it to be his "focus that he excels at" since he has such knowledge of the game. I saw him name all the players in order of their eviction from season one to current. If that isn’t an Aspies kid I don’t know what it is!
