This study examines 16-month-olds' understanding of word order and inflectional properties of familiar nouns and verbs. Infants preferred grammatical sentences over ungrammatical sentences when the ungrammaticality was cued by both misplaced inflection and word order reversal of nouns and verbs. Infants were also sensitive to inflection alone as a cue to grammaticality, but not word order alone. The preference for grammatical sentence forms was also disrupted when adjacent function word cues were removed from the stimuli, and when familiar content words were replaced by nonce words. These results suggest that sensitivity to the relationship between functional morphemes and content words, rather than sensitivity to either independently, drives the development of early grammatical knowledge. Furthermore, infants showed some ability to generalize from familiar to nonce content word contexts.

16个月大的孩子熟悉的惯用语单词和变形的语法接受能力。

这项研究考察了16个月大的孩子对熟悉的名词和动词的词序和词尾曲折性质的理解。当名词和动词的错位变形和词序颠倒都提示不合语法时，婴儿比不合语法的句子更喜欢合语法的句子。婴儿对语法的提示也仅对变形敏感，而对单词顺序则不敏感。当从刺激中删除相邻的功能词提示，以及用随机数词代替熟悉的内容词时，对语法句子形式的偏爱也被打乱。这些结果表明，对功能语素和内容词之间的关系的敏感性，而不是对其中一个独立的敏感性，驱动了早期语法知识的发展。此外，
