影响移动式显示中文文本阅读理解的主要因素

移动式显示方式是一种视觉显示终端（ＶＤＴ）上常见的动态显示方式。文章通过３个实验室实验研究了影响移动式显示方式下中文文本阅读理解的３个主要因素：移动速度、显示窗口长度和移动步幅。３３名大学生被试分别参加了３个实验。结果表明，移动速度对阅读理解是至关重要的因素，并且与显示窗口长度呈现出一定的交互作用趋势；移动步幅不影响中文的阅读理解。

Factors Affecting the Readability of Moving Chinese Text on VDT

Leading format is one of the common dynamic display types on all kinds of Visual Display Terminals(VDTs). In this article, three main factors affecting the readability of moving Chinese text were considered through three experiments.They were display rate,window length and jump step. 33 undergraduates took part in the three experiments respectively. The results showed that display rate was the most important factor to Chinese reading comprehension,and it also interacted with window length; jump step was the least important factor to Chinese reading comprehension when the Chinese text was displayed under leading format.
