对18个月大的婴儿在听到一个新的空间词时的空间分类进行了测试。当婴儿在习惯化过程中听到一个新的空间粒子时，形成了一种支持的抽象范畴表征(即，将一个物体放在另一个物体上)，但在沉默中观看事件时不会。具有产出性空间词汇的婴儿在听到与计数名词相同的新词时，不会区分支持关系。然而，当被呈现给新的计数名词时，还没有产生空间单词的婴儿确实注意到了支持关系。结果表明，18个月大的婴儿可以使用一个新的助词(可能由一个熟悉的动词辅助)来促进他们的空间归类，但这种效应的特异性因婴儿对空间语言的习得而不同。
Eighteen-month-olds' spatial categorization was tested when hearing a novel spatial word. Infants formed an abstract categorical representation of support (i.e., placing 1 object on another) when hearing a novel spatial particle during habituation but not when viewing the events in silence. Infants with a productive spatial vocabulary did not discriminate the support relation when hearing the same novel word as a count noun. However, infants who were not yet producing spatial words did attend to the support relation when presented with the novel count noun. The results indicate that 18-month-olds can use a novel particle (possibly assisted by a familiar verb) to facilitate their spatial categorization but that the specificity of this effect varies with infants' acquisition of spatial language.
