研究人员测试了10名专业和10名新手棒球击球手在虚拟环境中区分快速球和变速球的能力。他们使用了两种不同的反应模式：（a）非耦合反应，其中击球手口头预测投球类型;（B）耦合反应，其中击球手挥动棒球棒试图击中虚拟球。作者在6种视觉条件下操纵来自投手和球的视觉信息。当反应不耦合时，击球手在预测投球类型方面更准确。在耦合反应中，专家能够更好地使用前100个独立于投手运动学的球飞行。另外。高技术击球手的踏步方式与投手的运动学有关。而他们的挥杆时间与球速有关。这些研究结果表明，特定的任务要求决定是否一个高耦合的感知-行动环境提高预期性能。作者还强调了在表演者的自然环境中进行拦截动作研究的必要性。
The authors examined 10 expert and 10 novice baseball batters' ability to distinguish between a fastball and a change-up in a virtual environment. They used 2 different response modes: (a) an uncoupled response in which the batters verbally predicted the type of pitch and (b) a coupled response in which the batters swung a baseball bat to try and hit the Virtual ball. The authors manipulated visual information from the pitcher and ball in 6 Visual conditions. The batters were more accurate in predicting the type of pitch when the response was uncoupled. In Coupled responses, experts were better able to use the first 100 Ins of ball flight independently of the pitcher's kinematics. In addition. the skilled batters' stepping patterns were related to the pitcher's kinematics. whereas their swing time was related to ball speed. Those findings suggest that specific task requirements determine whether a hi highly Coupled perception-action environment improves anticipatory performance. The authors also high-light the need for research on interceptive actions to be conducted in the performer's natural environment.
