Well, it could be both. I have a dd like that - very visual-spatial, but also went through VT for eye tracking issues and OT for SPD (the OT inadvertantly helped the VT tremendously - long story. The OT was combined with listening therapy and took place in an OT gym.) A few years later, I am left wondering whether there is some visual perception issue in her brain - based on what happened in her last IQ test - since her eyes work together pretty well now. (Remind me please, next time we have a post-test conference, to bring a tape recorder so I can remember why I think this...)
