摘　　要：本研究以不同听力水平的汉英双语者为研究对象,通过开展听觉工作记忆实验,采用工作记忆的存储容量、加工准确度和加工速度作为测量指标,考察二语学习者听力个体差异的工作记忆效应。研究结果显示:1)工作记忆能力与听力水平显著相关,高水平者的加工速度促进加工准确度,而低水平者的加工速度却妨碍加工准确度和存储容量;2)听力高水平者在工作记忆的3项指标上都显著优于听力中、低水平者;而听力中、低水平者只在加工准确度上存在显著差异;3)存储容量和加工准确度对听力水平均有显著解释力,而加工速度的解释力不显著。This study investigates effects of working memory on individual differences in L2 listening comprehension through an auditory working memory experiment among Chinese-English bilinguals of different listening proficiency levels.Participants'storage capacity,processing accuracy and processing speed are all taken into account as measures of working memory capacity.The results indicate:1) working memory capacity is significantly correlated with listening proficiency,with processing speed facilitating high-proficiency listeners'accuracy while hindering low-proficiency listeners'storage capacity as well as accuracy;2) high-proficiency listeners outperform medium-and low-proficiency listeners in terms of all the three measurements,whereas medium-proficiency listeners only display a significantly higher accuracy than low-proficiency listeners;3) torage capacity and processing accuracy can account for variance in L2 listening comprehension,but processing speed cannot.
