Learning honorific request-making expressions in Korean during mobile text-chat tasks: Comparing provision of primes and recast prime

Abstract Linguistic alignment that occurs during interaction has been found to be a useful language learning mechanism. Recent second language (L2) research on alignment has primarily focused on syntactic alignment in face-to-face oral interactions (Kim & Michel, 2023). This study expands the scope of L2 alignment research by examining pragmatic alignment in group mobile text-chat tasks conducted in Korean. Furthermore, it investigates how the source of alignment (i.e., prime, recast) and learner factors (i.e., L2 proficiency, prior knowledge of the target feature, mobile literacy, and Korean typing skills) influence the extent of L2 alignment and subsequent alignment-driven language learning. Over a period of six days, 87 Korean language learners were randomly distributed across either a prime, recast prime, or control condition and completed the following: a background survey, a pretest, four alignment tasks, two posttests, and a Korean proficiency test. During the alignment text-chat tasks, learners used the KakaoTalk mobile text-chat application to interact with two native Korean speakers who elicited Korean honorific request-making expressions in specified scenarios. The prime group received model examples prior to their production, while the recast prime group received recasts in response to non-target-like production. The learners’ use of honorific expressions was evaluated for both suppliance and accuracy across the pretests, alignment task performance, and posttests. The results revealed evidence of pragmatic alignment, with the recast prime condition demonstrating greater effects on honorific request head acts compared to the prime condition. Additionally, prior knowledge of request-making strategies facilitated L2 alignment. The implications of pragmalinguistic development through alignment-driven text-chat tasks are further discussed.
