Abstract

Boosting, an authorial commitment, and hedging, a authorial mitigating, are two issues interconnected one another with a gaining importance in the last decades (for detail see Gillaerts & Velde, 2010). However, boosting has remained as an issue needing to be studied from different aspects; for instance, cross-linguistic, cross-disciplinary, cross-cultural or comparative while hedging gains a great deal of attention from researchers. The purpose of the present study is to investigate the corpora in terms of statistical inclusion of certainty markers in the research articles written in English by Turkish, Japanese and Anglophonic authors, and then to explain the results obtained through statistical tests in the sense of linguistic and cultural factors. A corpus of total 60 research articles written by 20 Anglophonic authors, 20 Japanese authors, and 20 Turkish authors of English constituted the data for the present study. The data were scanned by researchers of the present study. Having completed the scanning, the words functioning as boosters were categorized in line with the taxonomy created for the present study. Then, the total certainty markers for each group of scholars were calculated and analyzed through ANOVA test. The test results provided whether there were any statistically significant differences among the groups in terms of including boosters in the research papers. Furthermore, the present study formed a boosting list as a result of dictionary scanning, which may be a reference for further studies, and the most and the least used boosters of authors were gathered in the tables.
