This study aims to explore to what extent anxiety affects the whole process of three English majors writing their M.A. theses, as well as testing the relationships between anxiety and self-regulation in the whole process. The findings indicate that anxiety appears with high degree atthe preparation stage, slumps at the writing stage and reaches another high level at the revision stage. Anxiety also exists when negotiating with supervisors. What’s more, self-regulation has been proved to alleviate anxiety in the process of writing. This studycontributes new knowledge to the field by relating anxiety to self-regulation in the process of writing M.A. theses, yielding a deepened understanding of self-regulation that reduces anxiety in terms of the progress gradually achieved in the writing process. It alsohas implications for supervisors to pay attention to the way of negotiating with students that may cause anxiety during the academictheses writing process.展开更多
