I'm surprised about the working memory score....there is such a large difference between VCI and WMI, and he's never had problems with his memory or application of knowledge from memory. I'm thinking that it's so low due to anxiety?
Working memory is not all memory. I thought the same thing, my son has excellent memory. And the sub tests my tester did showed that others forms of memory were quite good. Working memory is the ability to store things in short term memory. For example if you are giving a string of numbers 8, 12, 7, 9, 45 and have to repeat them back. Since this is something I don't do well, I'm not surprised my son doesn't do well.
From my thread from yesterday, where I asked for a description of working memory.
A significantly lower score in working memory is one indication for calculating General Ability Index (GAI) as a supplement to Full Scale IQ (FSIQ). Find each occurrence of "working memory" in the 49-page
PDF for info.
