acs: My DS8 had the same issues with the WISC-IV!! He had a 42 point spread between his PRI and the WM, and a 29 point spread between his VCI and WM. I never really gave it a thought since most of the books say that the WM score drags the FSIQ down for most gifted kids. But he is a kid who has a photographic memory for anything that he has ever read or heard. And yet he scored really low on the WM. It made no sense to me.

Very, very, interesting!!

And for what it is worth, my DH has some symptoms of ADD (as do most of the boys in his family... a brother and cousins). But DS can sit and focus on books or building legos for hours at a time and not move a muscle. But if he is bored or unchallenged, then look out!!
