Six-month-old infants' ability to form an abstract category of containment was examined using a standard infant categorization task. Infants were habituated to 4 pairs of objects in a containment relation. Following habituation, infants were tested with a novel example of the familiar containment relation and an example of an unfamiliar relation. Results indicate that infants look reliably longer at the unfamiliar versus familiar relation, indicating that they can form a categorical representation of containment. A second experiment demonstrated that infants do not rely on object occlusion to discriminate containment from a support or a behind spatial relation. Together, the results indicate that by 6 months, infants can recognize a containment relation from different angles and across different pairs of objects.
使用标准的婴儿分类任务，研究了6个月大婴儿形成容纳抽象类别的能力。婴儿对处于容纳关系的4对物体形成习惯化。习惯化之后，用熟悉的容纳关系的一个新例子和一个不熟悉关系的例子对婴儿进行测试。结果表明，与熟悉关系相比，婴儿对不熟悉关系的注视时间明显更长，这表明他们可以形成容纳的类别表征。第二个实验表明，婴儿不依赖物体遮挡来区分容纳与支撑或背后的空间关系。综合来看，结果表明到6个月大时，婴儿可以从不同角度并跨越不同的物体对识别容纳关系。
