视知觉理论认为，阅读是经由眼睛接收文字、图片等符号，通过语境、上下文等知 识进行理解的过程，并在大脑中产生短时记忆。使用质化和量化相结合的方法，通过深 度访谈发现影响用户阅读新闻APP的主要因素，再开展眼动实验，研究这些因素如何作 用于阅读行为和理解记忆。结果显示：人们对新闻导读的关注度和阅读时长与信息密度 成正比，对新闻正文的关注度和阅读时间与图版率成正比，在色彩饱和度高的页面上阅 读停留的时间更长；新闻排序使得注视率呈现递减效应。但眼见未必等于记忆，新闻的 “头条效应”仅存在于视觉层面，APP页面中新闻二条的记忆效果更佳，新闻记忆受到 关注程度和阅读时长等因素的复杂影响。

According to the perception theory, reading is the process of receiving words, pictures and other symbols through the eyes, understanding in the context, and generating short-term memory in the brain. With the method of depth-interview and eye movement experiment, this paper study on what kind of factors can make in?uences on peoples’ reading on News APP, and how these factors affect memories on the news. The results illustrate that the information density has a positive correlation with people's attention and reading time on the guide column. The picture ratio has a positive correlation with people's attention and reading time on news contents. People spend more time reading on pages with high color saturation. The order of pages reduces the gaze effect on news. This paper also finds that the “headline effect” only existed on the visual level; the second headlines on news APP are more possible to be remembered. News memory is affected by factors such as attention and reading time.
