어휘접근 과정에서 나타나는 한국인 L2 학습자의 이중언어 음운적 동시활성화 양상

Abstract

This study explored the likelihood of cross-language co-activation among Korean L2 learners of English when performing a monolingual phoneme monitoring task. The stimulus onset asynchrony (SOA: -2,000ms, +200ms, +400ms) between picture and target phoneme stimuli were manipulated. Results demonstrated that participants responded faster and showed lower error rates when performing the task in L1 compared to L2. Moreover, interference effects were observed in all three SOA-manipulated experiments irrelevant to the language type, which shows the presence of phonological co-activation of the language not- in-use during monolingual task. Stronger L1 interference effect was shown during L2 task, which reflects the difference in the degree of bilingual phonological co-activation. This study suggests that when given a short period of time to access the semantic system which is shared by two languages, phonological information of both languages are co-activated even for non-proficient L2 learners whose languages have different scripts.
