Replication research in the domain of perceived L2 fluency: Approximate and close replications of Kormos and Dénes (2004) and Rossiter (2009)

Abstract

The primary objective of this paper is to contribute to the advancement of second language (L2) fluency research by outlining a specific proposal for future replication studies. The overarching goal is to assess the generalisability of the original findings of the two influential studies in the area of perceived fluency: Kormos and Dénes (2004) and Rossiter (2009). This objective will be achieved by first introducing the concept of L2 fluency that often conflates two categories: (1) overall language proficiency; (2) temporal features of speech production. The paper then highlights limitations in the current fluency research paradigm emphasising the variability in the methods employed for speech analysis and rating data collection. This diversity makes it somewhat challenging to compare results across various studies. In response to these challenges, the second part of the paper proposes several close and approximate replications of the two studies.
