输出任务类型对二语程式语附带习得的影响研究

The effect of output task-types on the incidental acquisition of L2 formulaic sequences

本研究考察四种类型的输出任务(包括聚焦型和非聚焦型)与一个输入任务对成人二语学习者在随后相关输入中对二语程式语的注意及附带习得的作用,以及该作用是否受到学习者二语水平的调节。结果发现:1)只有聚焦的输出任务才能提升学习者对程式语的注意,进而促进其习得;输出任务的聚焦程度越高,触发的注意加工程度就越深,习得效果就越好且具有持久性;2)学习者的二语水平不影响输出任务类型对程式语注意的作用,但却调节其对习得的效应。

This study examined the relative efficacy of four types of output tasks(including focused and unfocused output tasks)as compared to an input task,in promoting the noticing of L2 formulaic sequences in the subsequent input processing and their incidental acquisition,and explored whether L2 proficiency would mediate the task effects.The results showed that only the focused output tasks could facilitate the noticing and subsequent acquisition of formulaic sequences by adult L2 learners.The more focused an output task was,the more likely it would promote the noticing andprocessing of the target sequences,and thus their acquisition in both short and long terms.In addition,L2 proficiency didn't influence the task-type effects on the noticing of formulaic sequences but did moderate their acquisition.The results revealed some constraints on the noticing function of output and suggested some implications for the instruction of L2 formulaic sequences in classroom language teaching.
