L2 Processing of Linguistic and Nonlinguistic Information

Abstract

This study investigates how linguistic and nonlinguistic information interacts in second language (L2) sentence processing. Previous studies argued that L2 behaviors might stem from how L2 speakers rely more on one type of information over another. However, direct attempts have not been made to test the (dis)agreement of different information types. To fill this gap, the present study explored the integration of definiteness and real-world knowledge. Experiment 1 showed that both first language (L1) speakers (n = 34) and advanced L2 speakers (n = 49) could use definiteness to predict unmentioned referents, but intermediate L2 speakers could not (n = 35). After confirming that L1 and L2 speakers shared the same real-world knowledge, Experiment 2 (n (L1) = 36, n (L2) = 43) showed that the two groups’ behaviors differed when linguistic and nonlinguistic information had to be processed simultaneously. The findings suggest that L2 speakers can process linguistic information in a targetlike manner only in the absence of usable nonlinguistic information.
