对于成年人来说，关于个人可能的目标、偏好或倾向的先验信息在解释模糊的行为以及预测和解释新环境中的行为方面发挥着强大的作用。在两项研究中，我们调查了10个月大的婴儿是否能够通过看到演员直接追求并获得目标的先前实例来识别模糊动作序列的目标，以及婴儿是否可以使用这些先前信息来理解演员在新环境中的行为。实验1表明，目标预览影响婴儿的后续动作的理解，但只有当预览是在同一个房间的后续动作序列。实验2表明，婴儿未能在不同的情况下传递先前的目标信息是由于房间本身的变化，而不是任务的其他特征。我们的研究结果表明，婴儿可能会使用他们的理解简单的动作作为理解新奇或模糊的动作的杠杆点，但他们这样做的能力是有限的，以某些类型的上下文变化。
For adults, prior information about an individual's likely goals, preferences or dispositions plays a powerful role in interpreting ambiguous behavior and predicting and interpreting behavior in novel contexts. Across two studies, we investigated whether 10-month-old infants' ability to identify the goal of an ambiguous action sequence was facilitated by seeing prior instances in which the actor directly pursued and obtained her goal, and whether infants could use this prior information to understand the actor's behavior in a new context. Experiment 1 demonstrated that the goal preview impacted infants' subsequent action understanding, but only if the preview was delivered in the same room as the subsequent action sequence. Experiment 2 demonstrated that infants' failure to transfer prior goal information across situations arose from a change in the room per se and not other features of the task. Our results suggest that infants may use their understanding of simple actions as a leverage point for understanding novel or ambiguous actions, but that their ability to do so is limited to certain types of contextual changes.
