How can a boy who learns as easily as breathing and doesn't forget ANYTHING get such low working memory and processing speeds??
The WMI really is a test of short-term auditory memory. Gifted kids often have amazing long-term memories, but their short term memories for uninteresting facts (like a string of numbers) may or may not be fabulous. I wouldn't assume that his memory is poor based upon a lower WMI. With raw scores of 13 and 12, I'd guess that it falls around the 80 percentile, although that would be a rough guess on my behalf. Am I way off on that?
If more testing were done, would the SB5 be a more useful instrument?
Like a pp said, my understanding is that the SB5 favors mathematically inclined kids and generally nets lower overall scores than the WISC-IV. Deborah Ruf considers scores in the low 120s to be gifted on the SB5, FWIW.
