认知语言学视角下的语符频率与语类频率

Token and type frequency in the input—From the perspective of cognitive linguistics

以语言使用为基础的认知语言学派非常重视频率效应。近年来国外的研究对语符频率、语类频率及二者间的交互效应进行了很多探讨并取得一定成果。语符频率有助于巩固记忆表征，对非规则形式和习语的巩固和保持也有帮助，而语类频率对语言的能产性发挥着重要作用，充分利用语符频率与语类频率的偏态输入交互效应有助于语言习得。但是目前国内对这些成果鲜有介绍，实证研究更少。因此，本文旨在综述该领域的最新研究理论和成果，希望抛砖引玉，为二语习得研究和课堂教学带来启示。

Frequency effect has gained increasing attention from the Usage-based Theory of Cognitive Linguistics.The latest experimental researches revealed that token frequency helped to strengthen the memory representation and type frequency played a vital role in production. In addition， the skewed input with the interaction effect of token and type frequency would facilitate language acquisition. However， few review or empirical studies on this are found in China. Therefore， the present paper reviewed the latest researches and theories on token and type frequency in the input from the perspective of cognitive linguistics. More insightful findings are expected to help improve language acquisition and teaching.
