In the field of western psychology, although the research history of writing psychology is relatively short, the birth of Hayes-Flower model, the theoretical model of 1980 writing process, indicates that the research of writing psychology has generally matured. Flower and Hayes (L. Flower &; J.Hayes imagines writing as a set of thinking process, which consists of three main parts: task environment, students' long-term memory and students' working memory. The task environment includes students' writing tasks and external materials available to students, such as written content, composition reference books, abstract cards, etc. Because these materials are kept outside the students' minds, they are also called "external storage". Long-term memory refers to three kinds of knowledge related to writing (knowledge about theme, readers and rhetoric). It is a kind of declarative knowledge that can be directly described by language, so it is also called "declarative long-term memory". Students' working memory goes through three processes: planning (that is, conception), translation (that is, narration and writing) and review (including evaluation and revision). Flower and Hayes believe that working memory is a dynamic process, which is not linear, but has complex interaction and forms a spiral reciprocating form. Since then, burritos and Scarda Maria (Bereiter &; Scard Amalia (1987), Kellogg (1994) and others also made a deeper study of writing psychology from different angles on the basis of Hayes-Flower model. Chinese scholars, Dai Jianlin, Zhu and Zhang Tianding have also made many new discoveries in the study of writing psychology, which laid a solid foundation for our further research.

Flower and Hayes may be more inclined to study the field of psychology, and their introduction and discussion may only be found in relevant papers at present, and no monograph has been translated into China.

I hope it can be adopted, thank you!
