两岁奥尔兹对英语及物性的因果和非指定宾语交替中的动词进行了恰当的解释。在这里，我们探讨了他们如何做到这一点。因果动词和非指定宾语动词在句法上是相似的。它们既可以是及物的，也可以是不及物的，但它们赋予不及物句主语的语义角色不同（分别为undergoer和agent）。为了区分这两种变化中出现的动词，儿童必须在角色分配中发现这种差异。我们研究了输入的分布特征，作为关于这种角色差异的一个可能的信息来源。实验一表明，在儿童导向的语料库中，因果动词和未指定宾语动词的不及物主语生命性和名词在主语和宾语位置上的词汇重叠模式不同。实验2测试儿童的能力，使用这两个分布线索推断一个新的因果或未指定对象的动词的意义，通过分离的介绍一个新的动词的分布特性，其潜在的事件所指。孩子们仅仅通过听这个动词在句子中的使用就获得了关于这个动词的有用的组合信息，后来又检索到这些信息，把这个动词映射到一个适当的事件上。
Two-year-olds assign appropriate interpretations to verbs presented in two English transitivity alternations, the causal and unspecified-object alternations. Here we explored how they might do so. Causal and unspecified-object verbs are syntactically similar. They can be either transitive or intransitive, but differ in the semantic roles they assign to the subjects of intransitive sentences (undergoer and agent, respectively). To distinguish verbs presented in these two alternations, children must detect this difference in role assignments. We examined distributional features of the input as one possible source of information about this role difference. Experiment 1 showed that in a corpus of child-directed speech, causal and unspecified-object verbs differed in their patterns of intransitive-subject animacy and lexical overlap between nouns in subject and object positions. Experiment 2 tested children’s ability to use these two distributional cues to infer the meaning of a novel causal or unspecified-object verb, by separating the presentation of a novel verb’s distributional properties from its potential event referents. Children acquired useful combinatorial information about the novel verb simply by listening to its use in sentences, and later retrieved this information to map the verb to an appropriate event.
