Thanks Grinity

Yes, it is true that at least these children can use their intelligence to compensate better than perhaps otherwise.

I agree it is a little sad - when you see so much potential but there is difficulty accessing it.

I read somewhere that this sort of thing can be likened to a farrari caught in a traffic jam. Increasingly I am thinking that the huge disparity between working memory/ processing on one hand and verbal/performance on the other is perhaps the issue here (particularly WM).
