Infants of 18 and 24 months acquiring English were tested in a preferential looking task on their ability to detect ungrammaticalities caused by manipulating a single function word in sentences. Infants heard grammatical sentences in which the determiner the preceded a target noun, as well as three ungrammatical conditions in which the was either dropped, replaced by a nonsense function word (el), or replaced by an alternate English function word (and). Both the 18- and 24-month-old infants oriented faster and more accurately to a visual target following grammatical sentences. The results suggest that by 18 months of age, infants use their knowledge of determiners in sentence computation and in establishing reference.
对18个月和24个月大正在学习英语的婴儿进行了一项优先注视任务测试，以考察他们检测句子中单个功能词操作所导致的不符合语法情况的能力。婴儿们听到了限定词the位于目标名词之前的符合语法的句子，以及三种不符合语法的情况，即the被省略、被一个无意义的功能词（el）替代，或者被另一个英语功能词（and）替代。18个月和24个月大的婴儿在听到符合语法的句子后，都能更快、更准确地将目光转向视觉目标。结果表明，到18个月大时，婴儿在句子计算和建立指代关系时会运用他们对限定词的知识。
