Interesting, not heard this theory before. Can you explain further? Spatial awareness of actions above the eye line is one of the last areas of proprioception to develop in juniors (usually around 8 or 9 years of age - which is why learning to serve is tougher than hitting a ground when you learn as a kid), but I've not heard that processing outside information is faster vhen the object is above the eyeline?
