人们通常可以基于另一个人身体运动中可用的视觉信息来预测另一个人动作的结果。我们通过研究守门员如何预测足球中点球的方向来研究这个问题。具体目的是确定用于预测踢脚方向的信息是否最好表征为局部于特定身体段或分布于多个段。在实验1中，我们记录了足球运动员将球踢进球网时的动作。使用一种新的方法来分析运动捕捉数据，我们确定了本地和分布式信息的来源，这些信息是踢方向的可靠指标。在实验2和实验3中，受试者在脚与球接触之前观看踢球者的动作动画，并被指示判断踢球方向。判断是一致的使用分布式信息，与当地信息的可能小的贡献。
People can often anticipate the outcome of another person's actions based on visual information available in the movements of the other person's body. We investigated this problem by studying how goalkeepers anticipate the direction of a penalty kick in soccer. The specific aim was to determine whether the information used to anticipate kick direction is best characterized as local to a particular body segment or distributed across multiple segments. In Experiment 1, we recorded the movements of soccer players as they kicked balls into a net. Using a novel method for analyzing motion capture data, we identified sources of local and distributed information that were reliable indicators of kick direction. In Experiments 2 and 3, subjects were presented with animations of kickers' movements prior to foot-to-ball contact and instructed to judge kick direction. Judgments were consistent with the use of distributed information, with a possible small contribution of local information.
