最近的分析表明，儿童导向的言语包含分布规律，原则上可以支持幼儿发现不同的语法类别（名词，动词，形容词）。特别是，被称为频繁框架的分布单元似乎特别具有信息性（Mintz, 2003）。然而，分析几乎完全集中在可用的英文分布信息上。由于语言在语法形式的标记方式上存在很大差异，跨语言证据的缺乏代表了一个不幸的差距。因此，我们通过分析两种语言（西班牙语和英语）、句子位置（短语中间和短语结尾）以及语法形式（名词、动词、形容词）中常见框架中可用的分布信息，来推进发展证据。我们从CHILDES数据库中选择了6个亲子语料库（3个英文语料库，3个西班牙语语料库），并分析了儿童2岁时的输入；6岁以下。在每种语言中，频繁的框架确实为语法类别分配提供了系统的线索。我们还发现了这些框架在不同语言、句子位置和语法类别中的准确性差异。
Recent analyses have revealed that child-directed speech contains distributional regularities that could, in principle, support young children's discovery of distinct grammatical categories (noun, verb, adjective). In particular, a distributional unit known as the frequent frame appears to be especially informative (Mintz, 2003). However, analyses have focused almost exclusively on the distributional information available in English. Because languages differ considerably in how the grammatical forms are marked within utterances, the scarcity of cross-linguistic evidence represents an unfortunate gap. We therefore advance the developmental evidence by analyzing the distributional information available in frequent frames across two languages (Spanish and English), across sentence positions (phrase medial and phrase final), and across grammatical forms (noun, verb, adjective). We selected six parent–child corpora from the CHILDES database (three English; three Spanish), and analyzed the input when children were aged 2 ; 6 or younger. In each language, frequent frames did indeed offer systematic cues to grammatical category assignment. We also identify differences in the accuracy of these frames across languages, sentences positions and grammatical classes.
