Resumen de Surprise markers in applied linguistics research articles: a diachronic perspective
This paper reports on a corpus-based study of linguistic expressions of surprise (i.e., a type of attitude markers functioning as metadiscourse) in 160 applied linguistics research articles that were published in two periods of time separated by 30 years. Unlike previous research on metadiscourse, this study took a frame semantics perspective on surprise as a knowledge emotion and adopted a fine-grained, frame-based analytical framework to examine diachronic trends in the use of surprise markers and their co-occurrence with other types of metadiscourse (i.e., boosters, hedges, and self-mentions). Binary logistic regressions revealed that compared with research articles published earlier, those published more recently were 2.16 times more likely to express surprises triggered by prior knowledge, 2.37 times more likely to express surprises without providing an explanation, and 2.28 times more likely to indicate surprises without resolving them. These results can be explained in terms of the heuristic nature of surprise and the escalating pressure on academics to promote their research strategically.
