二语习得复杂性研究:复杂系统理论视角

A Study of the Complexity of SLA from the Perspective of Complex System Theory

以复杂系统理论为依据,对语言的动态特征、二语习得的互动性、非线性、蝴蝶效应现象及石化现象进行分析,多维探讨二语习得的复杂性。认为从复杂系统理论来看,语言是动态发展的,二语习得是一个复杂的非线性系统。二语习得是基于互动的发展过程,对初始条件敏感依赖,其子系统与社会环境因素相互作用,共同促进学习者中介语系统变化发展。

In light of complex system theory, the paper analyzes language dynamic features, the interaction, nonlinearity, butterfly effect and fossilization in second language acquisition （SLA） process, and probes into the complexity of SLA from many perspectives. It holds that language is dynamic, and SLA is a complex nonlinear system. SLA can be seen as a dynamic process based on interaction, so it is sensitive to and dependent on initial conditions. The subsystems of SLA interact with social environments, promoting the development of learners＇ interlanguage system.
