它使人类能够从有限的单词中构建出无限多的句子。人类语言的这种独特的生产力如何在语言发展过程中发挥作用仍然是一个激烈的争论。当孩子们听到由新学的单词组成的句子时，他们是从他们对单词类别的法律的组合的知识中进行归纳，还是依靠存储在记忆中的单词串来检测句法错误？使用实验室教授的新单词，我们记录了两岁奥尔兹和成年人的诱发反应电位（ERP），这些儿童和成年人听了包含训练期间未使用的句法上下文的语法和不语法句子。在幼儿中，不符合语法的单词使用，即使他们刚刚学会，诱导早期左前负（目标词开始后100-400毫秒），随后是后期后正（目标词开始后700-900毫秒），这在语法句子中没有观察到。这种迟发效应与成年人的P600非常相似，这表明幼儿和成年人执行类似的句法计算。因此，我们的研究结果表明，幼儿建立在线的期望，即将到来的话在一个句子中的句法类别。(C)2016年6月，作者。由Elsevier Ltd.发布。这是CC BY-NC-ND许可下的开放获取文章。
Syntax allows human beings to build an infinite number of sentences from a finite number of words. How this unique, productive power of human language unfolds over the course of language development is still hotly debated. When they listen to sentences comprising newly-learned words, do children generalize from their knowledge of the legal combinations of word categories or do they instead rely on strings of words stored in memory to detect syntactic errors? Using novel words taught in the lab, we recorded Evoked Response Potentials (ERPs) in two-year-olds and adults listening to grammatical and ungrammatical sentences containing syntactic contexts that had not been used during training. In toddlers, the ungrammatical use of words, even when they have been just learned, induced an early left anterior negativity (surfacing 100-400 ms after target word onset) followed by a late posterior positivity (surfacing 700-900 ms after target word onset) that was not observed in grammatical sentences. This late effect was remarkably similar to the P600 displayed by adults, suggesting that toddlers and adults perform similar syntactic computations. Our results thus show that toddlers build on-line expectations regarding the syntactic category of upcoming words in a sentence. (C) 2016 The Authors. Published by Elsevier Ltd.
