What are the differences between hand eye coordination and reflexes? So when one catches a ball, they must have a specific level of hand eye coordination and reflex / reactions in order to be able to catch the ball. What aspect of catching a ball is related to hand eye coordination and what aspect of it is related to reflexes / reactions? How would having good hand eye coordination help with catching a ball and how would having good reflexes help with catching the ball? Or are they both one and the same thing without any differences?
