Factors Influencing L2 Self-repair Behavior: The Role of L2 Proficiency, Attentional Control and L1 Self-repair Behavior.

Self-repairs, that is revisions of speech that speakers themselves initiate and complete (Salonen and Laakso in J Child Lang 36:859, 2009. https://doi.org/10.1017/s0305000908009240 ), are frequently used to observe the cognitive and linguistic processes underlying second language (L2) speech production. Previous research has shown that factors such as L2 proficiency, attentional control and native language (L1) self-repair behavior interact with L2 self-repair behavior. To our knowledge, however, no research has examined how these three factors interact within a cohort of L2 speakers. As such, the present study examined the proficiency scores, attentional control scores and L2 and L1 self-repair frequency data of 58 adult L2 English speakers of various proficiency levels. Regression results showed that while proficiency was not a significant predictor of L2 self-repair behavior, attentional control and L1 repair frequency together explained 40% of the variance. Results suggest that L2 self-repair behavior may be more closely linked to stable cognitive and personality traits than to L2 proficiency.
