DS's visual spatial ability doesn't seem to translate to his own body and where it is in space. So he could be holding a tray of food that is at a 45 degree angle with everything about to drop on the floor and he doesn't even notice. DD is good with "individual" sports like gymnastics or swimming but doesn't seem to have the processing speed necessary to do well with most sports with balls. So by the time her brain becomes aware that the ball is space X and she needs to do Y, the ball is somewhere else. The exception being maybe golf, where the ball doesn't move til you hit it. It would be interesting to do a study on people who are good athletes and if it correlates to processing speed, visual-spatial ability, etc. and which sports relate to which abilities.
