Geometric form perception and its role in reorienting process have been studied extensively in children, but little is known about its early origin in infancy. Here, we present findings of three experiments that used looking-time paradigm to test infants' sensitivity to geometric and feature information in two-dimensional visual display. One-year-old infants participated in spatial search tasks, which were manipulated regarding the display movement (static, visible rotation and invisible rotation) as a degree of disorientation. The results showed that infants were able to create expectation about a hiding location based on the geometry of a rectangle only in the directionally stable search space, whereas they were capable to use feature cues (color) for reorienting even in that condition when the spatial display was rotated and they were allowed to track the display motion. However, infants did not use either geometry or feature properties of 2-D space in an orientation invariant manner. The findings are discussed within the theory of reorientation with respect to the 2-dimensional space.
几何形状感知及其在重新定向过程中的作用在儿童中得到了广泛研究，但对于其在婴儿期的早期起源知之甚少。在这里，我们呈现了三个实验的结果，这些实验使用了注视时间范式来测试婴儿对二维视觉显示中几何和特征信息的敏感性。一岁的婴儿参与了空间搜索任务，这些任务根据显示运动（静态、可见旋转和不可见旋转）来操纵作为不同程度的定向障碍。结果表明，婴儿能够根据矩形的几何形状仅在定向稳定的搜索空间中对隐藏位置产生期望，而即使在空间显示旋转并且允许他们跟踪显示运动的情况下，他们也能够使用特征线索（颜色）进行重新定向。然而，婴儿并没有以不变的方式使用二维空间的几何或特征属性。该研究结果在二维空间的重新定向理论框架内进行了讨论。
