Irena-- Interesting. My son is "high avg" for digit span which is low comparatively but miles above both our PSI subtests. (His working memory is only a tad over one SD below his VCI.) This despite his very clear ADHD profile and diagnosis as well as his Dyspraxia. I usually find your son right in line with mine so I find this difference curious and wonder what is the functional difference between them that creates that variance. It's got my curiosity working. Thanks for sharing this.
