引入视频是大学英语考试提高测试效度的一次尝试，但考生是否观看视频直接影响到测试效度是否得到提升。通过分析答题时考生眼部录像、考后问卷和访谈数据，本研究发现考生在完成选择题时会看视频，而完成填空题时则基本不看。进一步分析完成选择题时考生的眼球运动，发现题目设计和音视频特征等多种因素影响考生观看视频。最后，研究者通过分析问卷和访谈数据，总结出考生具体观看的视频信息种类及其作用。

Using video in college English listening tests aims to improve test validity, however, whether test-takers watch the video determine whether such intention can be realized. After analysing the recording of test-takers’ eye movement, follow-up questionnaire and interview notes, we find that when answering multiple choice questions, test-takers tend to watch video, while in completing blank-filling questions, they opt not to watch it. Further analysis on test-takers eye movement reveals that factors, including test design, audio and video features, influence test-takers’ viewing patterns. Finally, after analysing the questionnaire and interview data, we summarize the types of visual messages that test-takers really pay attention to and their functions.
