Although much evidence indicates that young infants perceive unitary objects by analyzing patterns of motion, infants' abilities to perceive object unity by analyzing Gestalt properties and by integrating distinct views of an object over time are in dispute. To address these controversies, four experiments investigated adults' and infants' perception of the unity of a center-occluded, moving rod with misaligned visible edges. Both alignment information and depth information affected adults' and infants' perception of object unity in similar ways, and infants perceived object unity by integrating information about object features over time. However, infants perceived a moving, misaligned, three-dimensional object as indeterminate in its connectedness, whereas adults perceived it as connected behind the occluder. These findings indicate that the effectiveness of common motion in specifying unified surfaces across an occluder is reduced by misalignment of edges. Alignment information enhances perception of object unity either by serving directly as information for unity or by optimizing the detectability of motion-carried information for unity. In addition, young infants are able to retain information about edge orientation over short intervals in determining connectedness via a process of spatiotemporal integration.

物体统一感知中的运动和边缘敏感性

尽管许多证据表明幼儿通过分析运动模式来感知单一物体，但婴儿通过分析格式塔特性和随着时间的推移整合物体的不同视图来感知物体统一性的能力存在争议。为了解决这些争议，四个实验调查了成人和婴儿对中心遮挡的移动杆的统一性的看法，该杆具有未对齐的可见边缘。对齐信息和深度信息都以类似的方式影响成人和婴儿对物体统一性的感知，而婴儿通过整合有关物体特征的信息随着时间的推移来感知物体统一性。然而，婴儿认为移动的、错位的、三维物体的连通性是不确定的，而成年人则认为它在封堵器后面是连通的。这些发现表明，共同运动在指定遮挡物上的统一表面方面的有效性因边缘未对齐而降低。对齐信息通过直接用作统一信息或通过优化运动携带信息的可检测性来增强对对象统一的感知。此外，在通过时空整合过程确定连通性时，小婴儿能够在短时间内保留有关边缘方向的信息。
