语言磨蚀回归性的跨语言研究

Cross-language Studies in the Perspective of the Regression Hypothesis of Language Attrition

语言磨蚀是语言习得的逆过程，当受蚀者的语言能力出现退化时，语言成分磨蚀的顺序与其习得的顺序正相反，呈现回归性特征。国外验证回归性假说的实证研究涉及到多个语种的不同的语言层面。文章通过介绍西方的几个主要语种和日语，以及汉语作为第二语言的外语磨蚀的研究，分析了不同目的语在外语磨蚀中的表现及其回归速度。

When the language attritors suffer from language loss, the order of attrition is the reverse of language acquisition. The related studies have proved that the Regression Hypothesis involves various language items within different languages. The paper reviews some case studies related to the study of some Western languages, Japanese and Chinese as second languages, and analyzes their attrition features and regression speed.
