Wren-
I have no idea if this makes sense or not because we're new here! But my DS took the SB-V and I would have expected him to be off the charts in visual-spatial. He's an extremely visual kid, I sometimes think he has a photographic memory. He can also put together any set of legos you give him based on the directions. He's 5 years, 5 months. He's very auditory but on Silverman's description, he has ALL the markers for a visual-spatial learner. Noises, smells, huge ability to read body language. His former teacher said it was "nearly creepy" how good he was able to predict what someone might say, just based on their body language. He even interfered in a teacher squabble because he could tell from across the room they were arguing.

Visual-spatial was his lowest score, by almost 20 points and the one I believe skewed the FSIQ the most because of the massive range.

According to the tester, some areas he just didn't have exposure so he couldn't begin to answer the question. In others, he just didn't understand the perspective he was being asked to use. We were stunned because if you'd asked me, I would have expected him to ceiling in that subtest.

I don't know how to answer your question though... I have no idea if we were just way way off or if his visual-spatial skills actually didn't show up well on the test.
