This thread has been very helpful to me. I just had a look at DS7's WISC IV report done last year (when he was 6) - his WM is at 150 or >99.9%. I'm so puzzled because he can't seem to remember about capitalizing or writing full stops, and he has some problems with remembering instructions, at least with me.
Recently, he did a cognitiveMap test and his Auditory Memory score was very good too. And then the tester told me what he did - he'd drum out the digits with his fingers and keep repeating so that he could sort them out. He has some system to keep short term memory for numbers! I think it's because he hates to write math workings down and he's therefore compensating (?). But with daily verbal instructions or things he doesn't care for, the underlying capability shows through. So despite the scores, he does have issues.
Would anyone know of how to improve auditory memory?
