在两个实验中，我们记录了婴儿的眼球运动，以测试动作的效率是否会影响婴儿对抽象人物正在进行的动作的预期能力。在实验1中，我们发现，预测眼球运动引起的非有效和有效的行动，但预期的结果发生在更早的有效行动条件。实验2的目的是测试显着性的目标和可能性，自动外推的运动是部分负责实验1中的预测性注视转移的效果。我们发现，当自动外推被阻止，目标是不突出，婴儿表现出预测性的目光转移，只有在有效的行动条件。总之，我们的研究结果支持的重要性，目的论的推断，在预期的目标正在进行的行动。(C)2012 Elsevier Inc. All rights reserved.
In two experiments, we recorded infants' eye movements to test whether the efficiency of the action influences infants' ability to anticipate the outcome of an ongoing action performed by abstract figures. In Experiment 1, we found that predictive eye movements were elicited by both nonefficient and efficient actions, but anticipation of the outcome occurred much earlier in the efficient action condition. Experiment 2 was designed to test the effect of saliency of the goal and the possibility that automatic extrapolation of the movement was partly responsible for the predictive gaze shifts in Experiment 1. We found that when automatic extrapolation was prevented and the goal was not salient, infants showed predictive gaze shifts only in the efficient action condition. Taken together, our findings support the importance of teleological inferences in anticipating the goals of ongoing actions. (C) 2012 Elsevier Inc. All rights reserved.
