The progress of technology is constantly changing the way we read, and printed matter is gradually replaced by new equipment and technology platforms. However, when the scene of holding a book is replaced by the scene of holding a PDA, iPad, mobile phone or other equipment, it may not only be the material carrier of the text, but also our reading habits, reading experience, reading mode and even our cognitive way. [1][2][3][4][5] All these changes challenge the existing research results of cognition and learning theory, and also trigger new reading theory research.

"Electronic text" is sometimes called "digital text", which usually refers to nonlinear and interactive text based on computer. Text blocks or paragraphs are connected by links, and the media of text can include text, pictures, videos and sounds. Text links are sometimes explicit, such as selecting buttons such as "Up", "Down" or "Next"; Sometimes, the link is not clear, just as a word or phrase, such as in the window of the novel Irish Coffee, or on a map in the story of Romance of the Three Kingdoms. Generally speaking, these links do not provide guidance on how to develop the following plot. Readers can make their own decisions and choose their own links in reading.

Digital technology has changed the definitions of reading and books in the linear era. In the digital age, reading content includes not only text, but also charts, sounds, animations and other types of symbols. The definition of reading in the era of linear text is no longer applicable, so "reading" can be defined as "reading is a process of constructing meaning for symbols" Accordingly, the concept of "book" should also be "published related pages or screens". [6] These changes require readers to develop new decoding skills, or develop new reading forms or "super reading" abilities. We need to know whether the reading psychological representation theory based on paper text reading research can explain the reading process of electronic text. Psychological representation of electronic text reading: the level of psychological representation, the construction process of psychological representation, the influence of previous psychological representation on current reading, etc. , are all areas worth studying in the future. This paper will discuss the changes in reading process caused by the material support system of electronic texts, as well as the changes in reading experience and psychological representation construction.
