From early in development, segmenting events unfolding in the world in meaningful ways renders input more manageable and facilitates interpretation and prediction. Yet, little is known about how children process action structure in events composed of multiple coarse-grained actions. More importantly, little is known about the time course of action processing in young children or about the specific features that recruit attention. This is particularly true when we consider action that pauses unexpectedly—as actions sometimes do—thereby violating the expectation of a continuous unfolding of motion. We assessed visual preference to intact and disrupted actions embedded within a multiaction event in toddlers and adults. In 1 condition, pauses were inserted at intact action boundaries, whereas in the other condition, they disrupted action. Attention in both groups was recruited to the disrupted relative to intact events. Time-course analyses, however, revealed developmental differences in sensitivity to the movement features (e.g., motion, pauses, and transitions) of disrupted events.

动作中断：幼儿和成人动作违规处理中的动作和断点

从开发早期开始，以有意义的方式分割世界上正在发生的事件使输入更易于管理并促进解释和预测。然而，对于儿童如何处理由多个粗粒度动作组成的事件中的动作结构，我们知之甚少。更重要的是，人们对幼儿动作处理的时间过程或引起注意力的具体特征知之甚少。当我们考虑意外暂停的动作时尤其如此——就像动作有时那样——从而违反了对连续展开的运动的期望。我们评估了对幼儿和成人多动作事件中嵌入的完整和中断动作的视觉偏好。在一种情况下，停顿是在完整的动作边界处插入的，而在另一种情况下，它们会中断动作。两组的注意力都集中在与完整事件相关的中断事件上。然而，时间过程分析揭示了对中断事件的运动特征（例如，运动、暂停和过渡）的敏感性的发展差异。
