我们研究了6个月大的能力，代表闭塞的物体，使用角膜反射眼跟踪技术。实验一比较了婴儿的能力，推断当前的预遮挡轨迹与他们的能力，根据最近的经验，新的物体运动的预测。在第一种情况下，婴儿在第一次阻塞通道的渐近线（类似于2/3准确预测）处进行。在第二种情况下，所有的婴儿最初都不能做出准确的预测。然而，性能在两次闭塞通道后达到渐近线。这是第一项证明在遮挡任务期间具有如此快速学习效果的研究。实验2复制了这些效应，并证明了一个强大的记忆效应延长24小时。在封闭任务中，这种长期记忆效应以前只在14个月大的婴儿中观察到（摩尔和梅尔佐夫，2004）。(c)2006 Elsevier B. V.保留所有权利。
We examined 6-month-olds abilities to represent occluded objects, using a corneal-reflection eye-tracking technique. Experiment I compared infants' ability to extrapolate the current pre-occlusion trajectory with their ability to base predictions on recent experiences of novel object motions. In the first condition infants performed at asymptote (similar to 2/3 accurate predictions) from the first occlusion passage. In the second condition all infants initially failed to make accurate prediction. Performance, however, reached asymptote after two occlusion passages. This is the first study that demonstrates such rapid learning effects during an occlusion task. Experiment 2 replicates these effects and demonstrates a robust memory effect extending 24 h. In occlusion tasks such long-term memory effects have previously only been observed in 14-month-olds (Moore & Meltzoff, 2004). (c) 2006 Elsevier B.V. All rights reserved.
