閉合字幕對英語詞匯認知影響
 摘    要 本文旨在研究字幕對詞匯習得的影響，并通過實驗與數據分析的方法，對此論題進行了研究。深圳大學外國語學院英語系大一新生為此次實驗的實驗對象，有字幕組別與無字幕組別均所采用相同的影音材料與實驗方法。通過對數據的統計，論文對實驗對象在前后兩次測試中所得的分數進行了比較與分析，同時也對詞匯出現的頻率與詞性對詞匯習得的影響進行了討論與研究。結果發現：①字幕能有效地促進學生對詞匯的習得。觀看英文或中文字幕的學生均比在無字幕組別中的學生學會更多的詞匯。②詞匯的高出現頻率有助于學生對詞匯的習得。然而，詞匯在影視畫面中生動的視覺呈現，以及令人印象深刻的音頻效果能夠彌補詞匯因出現頻率低而不易被學會的劣勢，并且使那些在視覺上與聽覺上具有優勢的低頻率詞匯更易被學會。③相比較而言，普通名詞以及那些與普通名詞同時使用的動詞和形容詞更容易被學會。因為當這些詞匯出現的時候，屏幕上往往會出現與之相關的事物，而這提供了學生能學會該詞匯所需的信息與線索。

Effects of Closed Captions on English Vocabulary Acquisition

 Abstract: This study is designed to investigate the effects of captions on vocabulary acquisition. The discussion is based on the statistic results of pre- and posttest scores achieved by 4 groups of subjects who are freshmen from the English Department of Foreign Languages School of Shenzhen University. These subjects were shown the same video clip but with either different captions or no captions. The study also analyzes the influences of word frequency and part of speech on subjects’ performance. The findings show that: 1) Captions facilitated student’s vocabulary acquisition. Students watching the video clip with either English captions or Chinese captions learned more words than the other groups which did not have access to captions. 2) High word frequency usually helps students’ vocabulary acquisition. However, a vivid visual presentation of what a word describes and impressive sound effects could make up for low word frequency and made the low frequency word with these visual and audio complements easier to learn. 3) Common nouns and verbs and adjectives that are used with common nouns were comparatively easy to learn. When these words appeared, there were usually relevant objects available on the screen, by which students could refer to in order to understand the new word.
