Abstract

This study aimed to investigate the relationship between lexical coverage and TV viewing comprehension. Previous studies have indicated that 95% to 98% of lexical coverage may be needed for reading comprehension (Hu & Nation, 2000). To understand informal listening passages, lower coverage figures (95%-90%) may suffice. However, no study has researched the lexical coverage needed to understand audiovisual texts. We adopted a counter-balanced within-participants design, in which 5%, 10%, or 20% of the words in four 2-min documentaries were replaced with nonwords. Native and non-native speakers of English participated in this study. Results showed that comprehension scores decreased as lexical coverage decreased; comprehension at 100% coverage was significantly higher than 90% and 80% in the two groups; and optimal adequate comprehension is achieved with an optimal lexical coverage of 95%, whereas minimal adequate comprehension is reached with a minimal lexical coverage of 80%.

L1 和 L2 观看理解中的词汇覆盖率

本研究旨在探讨词汇覆盖率与电视观看理解之间的关系。以往的研究表明，阅读理解可能需要 95% 至 98% 的词汇覆盖率（Hu & Nation, 2000）。要理解非正式听力段落，较低的覆盖率（95%-90%）可能就足够了。然而，还没有任何研究对理解视听文本所需的词汇覆盖率进行过研究。我们采用了一种参与者内平衡设计，在四部 2 分钟的纪录片中，5%、10% 或 20% 的单词被替换为非单词。英语为母语和非母语的人都参与了这项研究。结果表明，随着词汇覆盖率的降低，理解力得分也随之降低；在两组中，100%覆盖率下的理解力明显高于 90% 和 80%；最佳词汇覆盖率为 95% 时，可达到最佳充分理解力，而最低词汇覆盖率为 80% 时，可达到最低充分理解力。
