L2 repair fluency through the lenses of L1 repair fluency, cognitive fluency, and language anxiety

Repairs (including false starts, repetitions, and different types of self-corrections) have been examined in second language (L2) speech fluency research as one dimension of (dis)fluent speech. However, in contrast to other dimensions of L2 speech fluency (speed and breakdown), repair fluency is not equally well understood: the results are mixed, and more research investigating the factors behind L2 repair fluency is needed. While some previous studies suggest links between first language (L1) and L2 repair fluency, to what extent L2 repairs are connected with cognitive and affective factors is less understood. To achieve a comprehensive view of the factors behind L2 repair fluency, we combine perspectives of L1 repair fluency, attention control, and language anxiety (LA) that have individually been shown to potentially affect L2 repairs but have rarely been examined together. We analyzed data from L1 Finnish and L2 English monologue speech tasks, a Stroop task in L1 and L2, and surveys for general and task-specific LA from 59 advanced users of English to investigate how L1 repair fluency, cognitive fluency, and LA are related to L2 repair fluency. Correlational analyses revealed that task-specific LA and certain Stroop measures were connected with L2 repair measures, while correlations between L1 and L2 repair fluency measures were weak. An analysis of repair profiles of participants displaying the highest levels of L2 repair fluency revealed that, overall, repairs are more common in the L2 than in the L1, but patterns regarding preferences for repair types vary across individuals. The study has methodological implications for psycholinguistic and SLA research into L2 repair fluency and broader implications for L2 classrooms and assessment.
