CFK-
i have a question. Does your son have any processing speed issues (like low coding score on WISC?). One of the theories floating around with my son is that his very slow processing speed, combined with giftedness, looked a heck of a lot like HFA or aspbergers. He has a really hard time getting a social situation going, but then is fine once friendships are established. We think his processing is impacting those initial, more difficult, interactions. We are also looking at his auditory processing as his visual/spatial is really incredibly good. So just curious if this might be an issue wiht your DS.
