My DD did the WPPSI 6 months ago, her three lowest scores were coding (10, she refused to do more than two of each example) and Picture Concepts and Completion, both of which she scored 13s. The rest of her scores were 17s (actually I think there was one 16).
It always seemed odd to me that DD#2 (both my DDs in fact) struggled most with these particular subtests, when i would have said their visual spatial skills were higher than their verbal.
DD#2 learned the alphabet as a 2yr old but did not learn to read until actively taught starting 6 months ago (at 4yrs9mths). She's learned to decode quickly and easily and is well ahead of her class, but continues to have trouble with reversals, keeping track of where she is up to and would refuse to even look at books with fonts she didn't like, small text or text over pictures. So I took her off to a behavioral optometrist yesterday and sure enough she has eye coordination, convergence, tracking and focus issues. I am a bit suspicious of BOs finding problems with every child they see, but I went for a reason and he was able to easily demonstrate for me the way that one of her eyes was flicking around trying to lock on when he asked her to focus on an object. I am also reassured that he is recommended glasses first and a short series of therapy sessions only if the glasses aren't enough.
My question is, does anybody know enough about these two WPPSI/WISC subtests and these visual issues to know if there was a likely impact on her test results? I know that visual issues can be complex and will not have equal impact on all visual skills. The BO did say that her problem would not cause her any issues with certain tasks (watching TV, craft were two he named). I know that when my eldest saw an OT two years ago she scored really highly on some visual based tasks and very low on others, he said he could tell she was great at Where's Wally but couldn't read. So I realise that the issues DD#2 has may have no bearing what so ever on the skills needed for those subtests but I am curious.
