| 中文摘要: |
| 探讨图文和视频两种信息形式以及简单和复杂两种任务复杂度如何在社交媒体查询情景中影响用户的信息偶遇程度。选取小红书APP作为实验材料，通过全程录屏收集定时查询任务中41名被试信息偶遇行为的量化指标，以答卷准确率为查询效果评估依据。结合问卷调查法与访谈法分析被试信息偶遇行为触发及记忆留存机制的差异。研究发现：相较于图文信息形式，视频形式更能有效触发信息偶遇；相较于主题词范围狭窄的简单查询任务，主题词范围广泛的复杂任务显著提升了信息偶遇的触发频率；相较于被动触发的信息偶遇，主动触发的信息偶遇更能让被试记住其信息内容。 |
| 英文摘要: |
| This study aims to explore how two types of information (text with image and video) and two levels of task complexity (simple and complex) affect the degree of users’ information encountering when querying on social media. We choose Xiaohongshu APP as the experimental platform to collect quantitative indicators of 41 subjects’ information encountering through screen recording of the whole process of the timed querying task, and evaluate query performance based on the accuracy of the answer sheets. We use a combination of questionnaires and interviews to analyze the differences in triggering and memory retention mechanism of the subjects’ information encountering. The study finds that videos are more effective in triggering information encountering than text and image. Complex querying tasks with a wide range of keywords significantly increase the frequency of information encountering compared to simple tasks with a narrow range of keywords. Actively triggered information encountering is more likely to make subjects remember the content than passively triggered information encountering. |
