It is not clear whether the critical features used to discriminate movements are identical to those involved in predicting the same movement's effects and consequently, whether the mechanisms underlying recognition and anticipation differ. We examined whether people rely on different kinematic information when required to recognize differences in the movement pattern in comparison to when they have to anticipate the outcome of these same movements. Naïve participants were presented with paired presentations of point-light animated tennis shots that ended at racket-ball contact. We instructed them either to judge whether the movements observed were the same or different or to predict shot direction (left vs. right). In addition, we locally manipulated the kinematics of point-light figures in an effort to identify the critical features used when making recognition and anticipation judgments. It appears that observers rely on different sources of information when required to recognize movement differences compared to when they need to anticipate the outcome of the same observed movements. Findings are discussed with reference to recent ideas focusing on the role of perceptual and motor resonance in perceptual judgments.
目前尚不清楚用于区分动作的关键特征是否与预测同一动作效果时所涉及的特征相同，因此，识别和预期背后的机制是否存在差异也不明确。我们研究了人们在需要识别动作模式差异时，与必须预测这些相同动作的结果时，是否依赖不同的运动学信息。向没有经验的参与者展示成对的点光动画网球击球，这些击球在球拍与球接触时结束。我们指示他们判断观察到的动作是相同还是不同，或者预测击球方向（左或右）。此外，我们局部操纵点光人物的运动学，以确定在进行识别和预期判断时所使用的关键特征。与需要预测相同观察到的动作结果时相比，观察者在需要识别动作差异时似乎依赖不同的信息来源。我们将结合最近关注感知和运动共振在感知判断中作用的观点来讨论这些发现。
