hi mnmom23
I remember when trying to figure out my 2E son that it mentioned "distracted with self" vs. "distracted by external stimuli" in one of the davidson articles that dealt with differentiating gifted from gifted plus aspergers (in addition to a whole bunch of other distinctions)..It said that chidlren with aspergers tend to be more internally distracted. Also, if you don't already have it, a great resource for figuring out what the second "E" is in "2E" is the Eide's book called "The Mislabeled Child"..very detailed explanation of all the disorders and how they can all look like one another. Also I don't want to suggest i think he has aspergers but i remember this discussion of types of distractions and thought it might be relevent to you.
