最近的研究表明，对于12-13个月大的婴儿来说，新单词（包括可数名词和形容词）突出了物体之间的共性，从而促进了物体类别的形成。目前的实验旨在更精确地捕捉这一现象的范围。我们的问题是，新单词（可数名词、形容词）是否从一开始就与基于类别的共性联系在一起，或者它们是否也能引导婴儿注意到更广泛的共性，包括物体之间基于属性的共性（如颜色、纹理）。结果表明，在12-13个月大的时候，婴儿已经开始区分作为可数名词呈现的新单词和作为可数名词呈现的新单词。流利的婴儿导向语中的形容词，以及(2)婴儿对新词汇的期望符合这种正在出现的敏感性。
Recent research has documented that for infants as young as 12–13 months of age, novel words (both count nouns and adjectives) highlight commonalities among objects and, in this way, foster the formation of object categories. The current experiment was designed to capture more precisely the scope of this phenomenon. We asked whether novel words (count nouns; adjectives) are linked specifically to category-based commonalities from the start, or whether they also direct infants' attention to a wider range of commonalities, including property-based commonalities among objects (e.g. color, texture). The results indicate that by 12–13 months, (1) infants have begun to distinguish between novel words presented as count nouns versus. adjectives in fluent, infant-directed speech, and (2) infants expectations for novel words accord with this emerging sensitivity.
