Abstract This paper aims to investigate the effects of recasts and working memory on the acquisition of Korean morphological causatives by advanced Chinese learners of Korean. Participants were randomly assigned to two groups: A experimental group and a control group. The experimental group received intensive recasts during task-based interaction, whereas the control group did not. The effects of recasts were measured by two types of tests: An elicited imitation test, as a measure of implicit knowledge, and an untimed grammaticality judgment test, as a measure of explicit knowledge. The findings are as follows. First, from the pretest to the delayed posttest, recasts facilitated the learners’ acquisition of causative construction by developing both their implicit and explicit knowledge. Second, the results of delayed posttests showed that recasts were more effective in aiding the development of implicit knowledge than explicit knowledge. Third, working memory was found to be a significant covariate in the facilitative effects of recasts on explicit knowledge; that is, it mediated the development of explicit knowledge via recasts as a significant individual difference factor. The effects of recasts were maintained even when the impact of working memory was controlled. (189 words)

重铸和工作记忆对内隐和外显知识发展的影响

摘要本文旨在研究重铸和工作记忆对朝鲜族高级汉语学习者获取朝鲜族形态成因的影响。参与者被随机分为两组：实验组和对照组。实验组在基于任务的交互过程中收到了密集的重铸，而对照组则没有。重铸的效果通过两种类型的测试来度量：引发的模仿测试，作为隐性知识的度量；以及非定时语法判断测试，作为显性知识的度量。结果如下。首先，从前测到延迟的后测，重铸通过发展学习者的内隐知识和外显知识，促进了他们对因果结构的习得。第二，延迟后测的结果表明，重铸比隐性知识更有效地帮助隐性知识的发展。第三，发现工作记忆是重铸对显性知识的促进作用的重要协变量。也就是说，它通过重铸作为显着的个体差异因素来介导显性知识的发展。即使控制了工作记忆的影响，重铸的效果也得以保持。（189个字）即使控制了工作记忆的影响，重铸的效果也得以保持。（189个字）即使控制了工作记忆的影响，重铸的效果也得以保持。（189个字）
