Plus, DS HATES being put on the spot or feel like he's being quizzed. Even if I ask him math questions that are obvious, he will sometimes refuse to answer. He apparently acted kind of silly while taking the WISC and was actually up and pacing around the room which is not like him at all (he does things like that when anxious)....I'm surprised he did as well on it as he did. I just can't see him defining vocabulary words for a stranger with more than one or two words, and it has nothing to do with his verbal knowledge, it's just something that he wouldn't want to do. HOwever if they asked the same questions on the computer and gave it to him in multiple choice format (even if there were 10 answer choices), he'd probably do great. It doesn't make sense to me that he scores so well for reading comprehension (school computerized testing over the 99th percentile) if his verbal IQ is average.
