With this article, I investigate a 2022 study by Suzuki and Kormos that explores the multidimensionality of oral fluency among a group of 128 Japanese second-language learners of English. This study intends to use “speaking task design” to elucidate the relationships between cognitive fluency (CF) and utterance fluency (UF), and more clearly delineate which linguistic aspects contribute most significantly to CF and UF.
Suzuki and Kormos undertake this analysis by employing four different speaking tasks (argumentative, picture narrative, reading-to-speaking, reading-while-listening-to-speaking) and a broad range of linguistic knowledge and fluency measures (vocabulary size, lexical retrieval speed, sentence construction skills, grammaticality judgments, articulatory speed). Through their use of structural equation modeling (SEM), Suzuki and Kormos’ main finding highlights the “complex interplay between the multidimensionality of CF and UF and speaking task types.” Although the contribution of processing speed for UF was found to be consistent regardless of speaking task, significant variation across tasks was found for speed and repair fluency.
This review article begins with a short overview of the Suzuki and Kormos (2022) study, followed by an outline of the critical findings. Consideration is then given to the study’s most robust results, followed by commentary on the weaker aspects of the research. I then close with a short discussion on the role of such a study within the broader field of fluency research and suggestions on how this study may be improved upon, and present various pedagogical implications of the research.
