I agree that low processing speed is not necessarily a problem per se. Especially where these are solidly average scores. Working memory is more interesting, as that is a striking difference between the subtests. Might have something to do with the diagnosis of attentional weaknesses. I am most interested in the substantial difference between picture concepts and the other two PRI subtests, as, if not for this low score, his WISC results (at least in the PRI) would be much more like his WPPSI results. In general, his abstract reasoning skills appear to be higher than his concrete skills (Similarities vs vocabulary, matrix reasoning vs picture concepts). The similarities-picture concepts difference is also highly unusual. It's almost as if combining verbal and visual information in problem-solving is more challenging for him than tackling either one on its own. Do you find that to be the case IRL?
