知觉发展的一个基本问题涉及婴儿如何在遮挡物施加的空间间隙中将部分隐藏的物体感知为统一的。人们对出生后头几个月知觉完成发展的时间过程以及支持婴儿统一知觉的一些视觉信息了解很多。本次调查的目的是检查此过程的输入。我们记录了 3 个月大婴儿参与标准物体统一任务时的眼球运动，发现习惯后偏好表明统一感知的婴儿与没有感知统一的婴儿之间的扫描模式存在系统差异。相对于非感知者，感知者在可见杆部分附近的扫描更可靠，并且在杆运动范围内更频繁地扫描。这些结果表明，新兴的物体概念与环境中可用的视觉信息以及信息拾取的过程密切相关。
A fundamental question of perceptual development concerns how infants come to perceive partly hidden objects as unified across a spatial gap imposed by an occluder. Much is known about the time course of development of perceptual completion during the first several months after birth, as well as some of the visual information that supports unity perception in infants. The goal of this investigation was to examine the inputs to this process. We recorded eye movements in 3-month-old infants as they participated in a standard object unity task and found systematic differences in scanning patterns between those infants whose post-habituation preferences were indicative of unity perception versus those infants who did not perceive unity. Perceivers, relative to nonperceivers, scanned more reliably in the vicinity of the visible rod parts and scanned more frequently across the range of rod motion. These results suggest that emerging object concepts are tied closely to available visual information in the environment, and the process of information pickup.
