Interactional Metadiscourse Markers in Scientific Texts (Based on Research Articles Written by Native and Non-Native Speakers)

The present research investigated textual representations of writer-reader interaction in academic writing. The focus of the study was on the use of metadiscourse markers, i.e., stance and engagement markers, in applied linguistics research articles (RAs) published in English and Persian, the former written by Persian and English-speaking researchers, and the latter by Persian-speaking researchers. A cross-cultural analysis of RAs revealed similarities and differences in how academic writers express their stance and interact with their readers. Among the stance markers, hedging devices were found to be more frequently used in English RAs for expressing the authors' position, regardless of their native language. Persian RAs, on the other hand, predominantly used attitude markers for that purpose. In terms of the engagement markers, directives were the most prominent linguistic features employed by the writers in their native language. However, they were significantly less frequent in English RAs written by Iranian scholars. Compared to native English writers, Iranian writers showed a slightly stronger tendency to use reader pronouns and personal asides in their native language. This study reinforces the impact of the writers' linguistic and contextual awareness of the first- and second-language academic discourse conventions on the establishment of a successful writer-reader interaction and effective communication of arguments in academic writing.
