中文摘要：

本文就Hauser、Chomsky和Fitch的“核心递归运算机制”假说以及由此在《认知》刊物上引发的争议进行了详细介绍。基于相关原文的论述，结合笔者在MIT访问期间与Chomsky及双方其他主要作者的高端对话，笔者发现Hauser、Chomsky、Fitch与Pinker、Jackendoff之间关于语言官能的争论焦点既不在语言的“递归”，也不在语言的“运算机制”，而在于“递归运算机制”是否为人类语言特有。笔者还发现，双方除了观点的不同，其争议还源于双方审视问题角度的不同。文章最后指出，语言官能的争议不仅主导了语言学的自身发展，还带动了其他交叉学科的发展。

英文摘要：

This thesis offers a detailed introduction to Hauser, Chomsky and Fitch＇s ＂core computational system of recursion＂ hypothesis which led to a heated debate on the faculty of language in Cognition. This＇work is based on the publications, together with discussions with Chomsky and some of the other main parties to the debate during the author＇s visit to MIT. One of the central findings is that the focus of the debate is neither on ＂the recursion-only hypothesis＂, nor on ＂the computational system＂, but on whether ＂the computational system of recursion＂ is unique to human language. Apart from their different opinions, the controversy is found to derive mainly from the different perspectives of the discussants. The debate on the faculty of language contributes not only to the development of linguistics itself, but also to the progress of some other neighbouring disciplines which interface with linguistics.
