This study assessed the extent to which visuospatial processing, as measured by visual scanning behaviour, was associated with infants' ability to recognize mirror image and structurally distinct three-dimensional objects. Simplified Shepard and Metzler (1971) images were employed. Using a remote eye-tracker, infants ages 10 to 17 months (n = 130) were familiarized to a target object that rotated 180° around its vertical axis. During test trials, infants saw either the target object or one of two types of novel objects (mirror image or a structurally distinct) rotating through the previously unseen 180°. Infants looked significantly longer at the rotated target than novel object in both the mirror image and structurally distinct condition. However, recognition did not emerge until the third test pair, suggesting that infants found this task difficult task. Analyses revealed a relationship between visual scanning of the novel object during test trials and recognition performance; infants who engaged in focused scanning of the novel object (i.e., attended primarily to the top or bottom of the object) during test trials were more likely to show recognition performance. The results of this experiment identified visual processes that support infants' ability to recognize 3D objects from a previously unseen perspective.

婴儿对三维形式的识别：镜像和结构上不同的对象

这项研究评估了通过视觉扫描行为测量的视觉空间处理与婴儿识别镜像和结构上不同的三维物体的能力相关的程度。使用了简化的 Shepard 和 Metzler (1971) 图像。使用远程眼动仪，10 至 17 个月大的婴儿（n = 130) 熟悉围绕其垂直轴旋转 180° 的目标对象。在测试试验中，婴儿看到目标物体或两种类型的新物体（镜像或结构不同）中的一种旋转了以前看不见的 180°。在镜像和结构不同的条件下，婴儿注视旋转目标的时间明显长于新物体。然而，直到第三对测试对才出现识别，这表明婴儿发现这项任务是一项艰巨的任务。分析揭示了测试试验期间新物体的视觉扫描与识别性能之间的关系；在测试期间对新物体进行聚焦扫描（即主要关注物体的顶部或底部）的婴儿更有可能表现出识别能力。
