Abstract

Abstract Captioned video is widely used to enhance second language (L2) learners’ exposure to oral input beyond the classroom setting, and captioning has been found to provide an instantaneous, useful visual aid for parsing and understanding L2 oral discourse. Nevertheless, a meta-analysis has shown that captioning exerts a selective effect on L2 learners with different profiles. This study investigated whether L2 learners’ modality preferences (visual vs. auditory) and working memory capacity (high vs. low) would modulate the effect of full captions on L2 listening outcome. Results from 60 participants revealed that both cognitive variables affected their L2 listening to different extents. Notably, working memory capacity modulates the impact of L2 learners’ preferred modality on their listening outcome. Modality preference did not exert any significant impact on the listening outcome of L2 learners with lower working memory capacity. For L2 learners with high working memory capacity, their modality preference played a pivotal role in modulating their listening outcome; in this case, auditory learners had the best listening performance viewing the video without captions, whereas visual learners did best when watching the captioned video. These findings speak to the need for taking individual differences into consideration when employing captioned videos.

模态偏好和工作记忆能力对字幕视频提高二语听力效果的影响
摘要字幕视频被广泛用于增强第二语言(L2)学习者在课堂环境之外的口头输入,字幕被发现为解析和理解第二语言口头话语提供了即时、有用的视觉帮助。然而,一项荟萃分析表明,字幕对具有不同特征的二语学习者具有选择性作用。本研究调查了二语学习者的模态偏好(视觉与听觉)和工作记忆能力(高与低)是否会调节完整字幕对二语听力结果的影响。来自60名参与者的研究结果显示,这两个认知变量对他们的二语听力都有不同程度的影响。值得注意的是,工作记忆能力调节了二语学习者偏好模态对其听力结果的影响。情态偏好对工作记忆能力较低的二语学习者的听力结果没有显著影响。对于具有高工作记忆能力的二语学习者来说,他们的模态偏好在调节他们的听力结果方面起着关键作用;在这种情况下,听觉学习者在观看没有字幕的视频时表现最好,而视觉学习者在看有字幕的视频中表现最好。这些发现表明,在使用字幕视频时,需要考虑个人差异。
