From Interlanguage grammar to target grammar in L2 processing of definiteness as uniqueness

This study investigated the processing of English articles by second language (L2) speakers whose first language (L1) is Korean. Previous studies in L2 English article use had some issues unresolved such as using offline tasks, conflating definiteness with real-world knowledge, and operationalizing definiteness and relevant constructs in ways that participants can be primed or get metalinguistic cues. To revisit such issues, the construct ‘definiteness’ was operationalized as unique identifiability, a self-paced reading task was used to collect data, and regression models were employed to analyse logarithm residuals of raw reading time data, which can detect subtle differences that are otherwise buried. The results show that L1 speakers show sensitivity to the use of definite and indefinite articles in response to given contexts and that both advanced and intermediate L2 speakers first resort to their non-target-like Interlanguage grammar, but the advanced group later revises their initial interpretation and eventually shows the effect of target grammar. The L2 behavior is discussed in terms of its theoretical implications.
