Hedging Functions in Malaysian Doctoral Candidature Defense Sessions

The main aim of the present study is to build knowledge and understanding regarding the linguistic use of hedging by Malaysian speakers of English in academic spoken discourse and, more specifically, doctorate students presenting their thesis in the candidature defense. It looks not only to describe the specific nature of spoken academic hedging in Malaysia but to make inroads into identifying cultural factors that shape the way this hedging takes place. To realize these aims, a corpus-based investigative case study that used both quantitative and qualitative methods was used. Transcriptions of candidature defenses and semi-structured interviews regarding the nature of doctoral candidature defense were used to gather the data. The study found that national culture and the dynamic power distance in the educational culture surrounding the defense had an effect on the interpersonal hedging used by Malaysian speakers and the gap in hedging use between panel members and candidates. Disciplinary culture was also observed to influence hedging, specifically in referencing other work and testing theory to build an argument.
