In a series of 3 experiments, the authors examined the ability of badminton players of different skill levels (12 experts and 12 nonexperts) to anticipate the direction of badminton strokes. Participants viewed either film or point-light displays under a range of temporal or spatial occlusion conditions. World-class players were able to consistently pick up useful predictive information from the advance (precontact) kinematics of both the lower body and the racquet when the motion of those features was presented in isolation, whereas recreational players' use of the same information depended on the concurrent presence of linked segments. Participants' information pickup closely matched key biomechanical changes in the movement pattern being viewed, although, contrary to a common-coding view of perception and action (e.g., W. Prinz, 1997), some important differences were evident between the characteristics of the experts' movement prediction and those of expert movement production.
在一系列3个实验中，作者考察了不同技术水平的羽毛球运动员（12名专家级和12名非专家级）预测羽毛球击球方向的能力。参与者在一系列时间或空间遮挡条件下观看影片或点光显示。当这些特征的运动单独呈现时，世界级选手能够始终如一地从下半身和球拍的提前（接触前）运动学中提取有用的预测信息，而业余选手对相同信息的利用则取决于相连节段的同时存在。参与者的信息提取与所观看运动模式中的关键生物力学变化密切匹配，不过，与感知和行动的共同编码观点（例如，W.普林茨，1997）相反，专家的运动预测特征与专家运动产生的特征之间存在一些明显差异。
