Recent work on emerging sign languages provides evidence for how key properties of linguistic systems are created. Here we use laboratory experiments to investigate the contribution of two specific mechanisms-interaction and transmission-to the emergence of a manual communication system in silent gesturers. We show that the combined effects of these mechanisms, rather than either alone, maintain communicative efficiency, and lead to a gradual increase of regularity and systematic structure. The gestures initially produced by participants are unsystematic and resemble pantomime, but come to develop key language-like properties similar to those documented in newly emerging sign systems.
最近关于新兴手语的研究为语言系统的关键属性是如何产生的提供了证据。在这里，我们使用实验室实验来研究两种特定机制——互动和传播——对手语无声手势者的手动交际系统的产生的贡献。我们表明，这些机制的综合作用，而不是单一作用，维持了交际效率，并导致了规律性和系统性结构的逐渐增加。参与者最初产生的手势是无系统的，类似于哑剧，但逐渐发展出关键的类似语言的属性，这些属性类似于新出现的手语系统中记录的属性。
