The current study investigated infant spatial categorization of a support relation across differences in the perceptual features of the objects. Infants of 8 and 14 months (N = 67) were habituated to dynamic support events with objects that were plain and monochromatic or those that were embellished with decorations (e.g., polka dots, feathers). Infants were then tested with events that presented a novel pair of objects, a novel spatial relation (i.e., containment), or both. Infants, particularly those of 8 months, formed an abstract categorical representation of a support relation when habituated with the decorated objects but not the plain objects. The results suggest that the perceptual features of objects can facilitate infants' categorization of spatial relations, at least in some learning settings and especially with younger infants.
当前的研究调查了婴儿在物体感知特征存在差异的情况下对支撑关系的空间分类。8个月和14个月大的婴儿（N = 67）对由纯色单色物体或带有装饰（如圆点、羽毛）的物体构成的动态支撑事件进行了习惯化训练。然后，用呈现一对新物体、一种新的空间关系（即包含关系）或两者皆有的事件对婴儿进行测试。婴儿，尤其是8个月大的婴儿，在对带有装饰的物体而非纯色物体进行习惯化训练时，形成了支撑关系的抽象类别表征。结果表明，物体的感知特征可以促进婴儿对空间关系的分类，至少在某些学习情境中是这样，尤其是对于较小的婴儿。
