采用原位时间遮挡范式，考察了拦截任务中知觉-动作耦合与预期技能之间的关系。熟练的和新手板球击球手被要求在四种感知-动作耦合增加的平衡反应条件下预测球向他们投掷的方向：(I)言语，(Ii)仅下半身移动，(Iii)全身移动(无球棒)，和(Iv)带球棒的全身移动(即，通常的击球反应)。研究发现，当反应基于无球飞行或早期球飞行信息时，熟练的但不是新手的预期作为耦合函数而改善，与口头预测相比，即使是需要最低程度的身体运动来提高预期的反应也是如此。最重要的是，使用球拍的全身运动比不使用球拍的同等运动更能引起人们的期待。这一结果突显了要求和/或进行棒球拦截的机会在引起技术差异以进行预期方面可能起到的重要作用。结果验证了使用与自然操作环境密切相关的实验条件和任务要求的重要性，以充分揭示专家优势的本质。皇冠版权所有(C)2010由爱思唯尔出版。保留所有权利。
The relationship between perception-action coupling and anticipatory skill in an interceptive task was examined using an in-situ temporal occlusion paradigm. Skilled and novice cricket batsmen were required to predict the direction of balls bowled towards them under four counterbalanced response conditions of increasing perception-action coupling: (i) verbal, (ii) lower-body movement only, (iii) full-body movement (no bat), and (iv) full-body movement with bat (i.e., the usual batting response). Skilled but not novice anticipation was found to improve as a function of coupling when responses were based on either no ball-flight, or early ball-flight information, with a response requiring even the lowest degree of body movement found to enhance anticipation when compared to a verbal prediction. Most importantly, a full-body movement using a bat elicited greater anticipation than an equivalent movement with no bat. This result highlights the important role that the requirement and/or opportunity to make bat-ball interception may play in eliciting skill differences for anticipation. Results verify the importance of using experimental conditions and task demands that closely reflect the natural performance environment in order to reveal the full nature of the expert advantage.
