Horne JW (2000) Keep your eye off the ball. Nature Neuroscience, 3(12):1236    
The frequently heard coach's advice, "Keep your eye on the ball", may not be the best approach, suggests a new study on page 1236 of this issue*. The authors used the cricket batsman's challenge (how to react to a fast-approaching ball) to address how athletes use visual cues to produce rapid and accurate motor responses. Previous theories proposed that a batsman must use direct visual measurements, such as image expansion or the rate of change of binocular disparity, to predict the ball's trajectory. However, given that the batsman has only a fraction of a second to monitor such visual cues, it has been controversial whether these parameters could be measured accurately enough to guide the correct response
