物体感知的时空连续性取决于它们在空间布局中移动时出现和消失的方式。这项研究调查了婴儿对短暂遮挡物体的预测跟踪是否对该物体消失和重新出现的方式敏感。向 5、7 和 9 个月大的婴儿展示一个球在视觉场景中滚动，并通过动态遮挡、瞬时消失、内爆或虚拟遮挡短暂消失。三种不同的测量结果表明，预测性跟踪随着年龄的增长而增加，并且婴儿最有可能预测到运动闭塞后球的重新出现。这些结果表明，婴儿对物体的持久性和非持久性的了解体现在他们的预测跟踪中。
The perceived spatiotemporal continuity of objects depends on the way they appear and disappear as they move in the spatial layout. This study investigated whether infants' predictive tracking of a briefly occluded object is sensitive to the manner by which the object disappears and reappears. Five-, 7-, and 9-month-old infants were shown a ball rolling across a visual scene and briefly disappearing via kinetic occlusion, instantaneous disappearance, implosion, or virtual occlusion. Three different measures converged to show that predictive tracking increased with age and that infants were most likely to anticipate the reappearance of the ball following kinetic occlusion. These results suggest that infants' knowledge of the permanence and nonpermanence of objects is embodied in their predictive tracking.
