Abstract This study contributes empirical evidence regarding communicative functions in the pre-grammatical period. The aim was to explore these functions in child-adult dyadic interactions during what in language acquisition research has been called the two-word period. The study draws from the data corpus of a child 19–29 months old and the system of sign categories (gestures, non-verbal vocalizations, verbal vocalizations, uni- and bimodal compositions) developed by Rodríguez & Español. In order to study the communicative functions in this period, an observational code was developed in accordance with Strauss and Corbin’s Constant Comparative Method, which is suitable for encompassing the entire repertoire of a child’s sign use. The study in general allowed some functions absent in adult communication to be identified, and the qualitative analysis in particular revealed a use of semiotic resources that supports the idea of a cognitive processing structure common to gesture and word.

语法前阶段的交流功能：一个案例研究/语法前的共同作用

摘要这项研究为语法前时期的交际功能提供了经验证据。目的是在语言习得研究中被称为“两个词的时期”中探索儿童与成年人的二元互动中的这些功能。该研究取材于Rodríguez＆Español开发的19-29个月大儿童的数据语料库和符号类别系统（手势，非语言发声，言语发声，单峰和双峰构图）。为了研究这段时期的交际功能，根据斯特劳斯和科宾的“常量比较法”开发了一种观察代码，该代码适用于涵盖儿童手语使用的全部功能。一般而言，这项研究可以确定成人交流中缺少的一些功能，
