This study reports on a corpus analysis of the research articles published by Iranians, Chinese, and Turkish authors in the Reading Matrix journal. For this purpose, 62 research articles (373000 words) were meticulously analyzed to determine how the authors project their identities through different types of self-mention practices. Results of the analysis revealed that Chinese authors projected stronger identities in comparison to their Iranian and Turkish counterparts. However, authors from these three nationalities are still far from claiming the identity comparable in quality to that of experienced writers of the field. Findings of this study would be helpful to instructors of L2 writing and research methodology in order to make their students aware of possible self-mention practices and to help them adopt right and timely identities in their publications.
