在快速球类运动中，击球手在球的整个飞行过程中不会将视线与球对齐；相反，他们使用预测性眼球运动策略，这有助于提高他们的拦截技能水平。现有的研究声称：(1)棒球和板球击球手无法追踪球，因为球的移动速度太快，眼睛无法追踪，因此(2)击球手在击球的那一刻没有——可能也不可能——看球。然而，到目前为止，还没有研究调查过真正的精英击球手的目光。我们检查了两位世界上最好的板球击球手的眼睛和头部运动，发现这两种说法都不适用于这些击球手。值得注意的是，击球手将头部的旋转与球的运动结合在一起，确保球相对于他们的头部保持一致的方向。为此，只要击球手转动他们的头，保持眼睛不动，球就可以被追上。相反，我们展示了优秀的击球手使用独特的眼球运动策略，通常依靠两次预测扫视来预测(i)球反弹的位置，以及（ii）击球的位置，确保他们在击球时可以将目光投向球。这些特定的头眼运动策略在促进拦截专业知识方面发挥着重要的功能作用。
Hitters in fast ball-sports do not align their gaze with the ball throughout ball-flight; rather, they use predictive eye movement strategies that contribute towards their level of interceptive skill. Existing studies claim that (i) baseball and cricket batters cannot track the ball because it moves too quickly to be tracked by the eyes, and that consequently (ii) batters do not – and possibly cannot – watch the ball at the moment they hit it. However, to date no studies have examined the gaze of truly elite batters. We examined the eye and head movements of two of the world’s best cricket batters and found both claims do not apply to these batters. Remarkably, the batters coupled the rotation of their head to the movement of the ball, ensuring the ball remained in a consistent direction relative to their head. To this end, the ball could be followed if the batters simply moved their head and kept their eyes still. Instead of doing so, we show the elite batters used distinctive eye movement strategies, usually relying on two predictive saccades to anticipate (i) the location of ball-bounce, and (ii) the location of bat-ball contact, ensuring they could direct their gaze towards the ball as they hit it. These specific head and eye movement strategies play important functional roles in contributing towards interceptive expertise.
