我们研究了人工语言中非相邻依赖学习的发展轨迹。婴儿暴露于2种人工语言中的1种，其发音形式为[aXc或bXd]（语法1）或[aXd或bXc]（语法2）。在两种语言中，话语的语法性取决于第一和第三成分之间的关系，而中间成分则自由变化。已知中间元素的高度可变性有助于感知不相邻的依赖关系（Gomez，2002），但这种学习的发展轨迹尚不清楚。实验1复制了Gomez的研究，使用了更年轻的年龄组和更微妙的变异性操作。在这里测试的条件下（实验2a和2b），15个月奥尔兹无法跟踪非相邻依赖关系，但到15个月大的婴儿开始跟踪这种结构（实验3）。这种学习对于理解婴儿如何开始获得自然语言中的类似结构具有意义。
We investigated the developmental trajectory of nonadjacent dependency learning in an artificial language. Infants were exposed to 1 of 2 artificial languages with utterances of the form [aXc or bXd] (Grammar 1) or [aXd or bXc] (Grammar 2). In both languages, the grammaticality of an utterance depended on the relation between the 1st and 3rd elements, whereas the intervening element varied freely. High variability of the middle element is known to contribute to perception of nonadjacent dependencies (Gomez, 2002), but the developmental trajectory of such learning is unknown. Experiment 1 replicated the study of Gomez with a younger age group and a more subtle variability manipulation. Twelve-month-olds failed to track nonadjacent dependencies under conditions tested here (Experiments 2a and 2b), but by 15 months, infants are beginning to track this structure (Experiment 3). Such learning has implications for understanding how infants might begin to acquire similar structure in natural language.
