I am no expert in the tests that are administered so hopefully some of the experts here will jump on board. My DS6 is a deep slow thinker. On first glance it looks like he is trying to "beat" the test; however after talking to him about his choices on the test, it seems he is trying to cover up his "weaknesses". Could this be going on with your DS? I also believe that the more creatively-minded see many possibilities for an answer. Example: If there are 2 fruits (apple and orange) and 1 vegetable (tomato) and the question is to circle the 2 that "match", the creative mind gets overwhelmed because he/she thinks "Do they want the red ones? or the fruit? or the ones that grow on trees? or the round ones? etc. You get the jist.
I also could be wrong here but I think the SBV has no timed portions which might be better suited to your deep thinker. Again I am no expert on the tests, I just wish I would have asked for the SBV instead of the WISCIV for my deep thinker who does not do timed tests well at all.
