Thank you Aeh! I did read that it's psychometric qualities aren't as strong as you wrote, which made me wonder. His working memory score on the WISC IV was 123, so high average I believe. Had no idea the norms were so old. To give you more data on the WCST:
Total errors SS 99, 47 percentile
Conceptual Level response SS 95, 37 percentile
Categories completed ss 3 out of 5, >16 highest score possible
I'm also wondering what each executive function test is targeting. Am I right that the D-KES is assessing visual attention, NEPSY - auditory attention, and CPT general sustained attention?
Thank so much - your help is greatly appreciated!!
