Expressions of confusion in research articles: a diachronic cross-disciplinary investigation

Linguistic expressions of confusion, namely confusion markers, construe discrepancies between an academic author's prior knowledge and the information received. These emotive responses motivate knowledge-seeking behaviors to dissolve cognitive incongruities and are inherently connected with knowledge-making. Limited research has, however, examined how they partake in knowledge construction and dissemination in academic writing. Drawing on a frame-based analytical approach, this study investigated how an academic author's disciplinary background and time of publication may mediate the use of confusion markers in 640 research articles sampled from four disciplines. The corpus-based analyses were complemented by insights from 16 specialists to explore how considerations underlying their use of confusion markers shaped their academic writing. The findings indicated that the overall use of confusion markers changed over time and that disciplinary background and time of publication were significant predictors of several frame elements. The observed disciplinary and diachronic patterns of use can be explained in terms of epistemological orientations, developments in the academic world such as increasing disciplinary specialization and growing interdisciplinary research leading to a broadening of readership, and stiff competition in scholarly publication.
