As someone with a horrible working memory, holy moly that must be awesome!
I don't think I have ever seen a WM that high.
I know, and it definitely shows. I'm amazed at the things she's able to remember. Where it really shows is when she does multi-step math problems in her head that I would normally have to work out on paper. For instance, she can do 3 and 4 digit subtraction problems working left to right in her head. I honestly don't know how she does it.
We used to wonder if she had ADD because of the daydreaming in kindergarten and 1st but now I think it was just boredom.
