Abstract
This study conceptually replicated Huensch and Tracy-Ventura’s (2017) analysis of the relationship between L1 and L2 utterance fluency with adult L1-English learners of Spanish. Data from 88 participants were analyzed to explore the proportion of the variance in L2 fluency measures that can be attributed to the corresponding L1 measures, and the relative weights of L1 fluency and L2 proficiency as predictors of L2 fluency. This study applied the same fluency and proficiency constructs and operationalizations as the original study, but differed in task type and learners’ L2 proficiency. Results were most similar for speed and repair frequency, and for silent pause duration. Findings concerning silent and filled pause frequency differed. Combined, the studies show that some L1-L2 fluency relationships are relatively stable across proficiency levels, task type, and learning context.
