摘要：One of the major puzzles in linguistic research is why second language learners often fail to achieve full native competence in their second language, as is evidenced by differences in their linguistic performance compared to that of native speakers. An influential hypothesis on second language acquisition is the Interface Hypothesis (Sorace & Filiaci, 2006; Sorace, 2011). According to this hypothesis, acquiring properties of the second language that reside in one linguistic domain (such as syntax or phonology) is not problematic, but acquiring properties of the second language that lie at the interface between syntax and another cognitive domain (in particular the interface between syntax and pragmatics) is difficult. This hypothesis was inspired by the finding that, in a test of subject pronoun interpretation, highly proficient, near-native speakers of L2 Italian gave different responses from monolingual native Italian speakers with respect to overt pronouns (Sorace & Filiaci, 2006). This contrasted with their interpretation of null subjects, which was native-like.
其他摘要：How do second language learners acquire form-meaning associations in the second language that are inconsistent with their first language? In this study, we focus on subject pronouns in Italian and Dutch. A native speaker of the non-null subject language Dutch learning the null subject language Italian as a second language will not only have to learn to use and comprehend null pronouns, but will also have to learn to use and comprehend overt pronouns differently in the L2 than in the L1. The interpretation of Italian overt pronouns, but not of Dutch overt pronouns or Italian null pronouns, has been argued to require perspective taking, specifically the use of hypotheses about the conversational partner’s communicative choices to guide one’s own choices. Therefore, a related question is how perspective taking and cognitive constraints influence L2 acquisition of such forms. Using computational cognitive modelling, this study explores two learning scenarios. In cognitive model 1, second language acquisition proceeds in the same way as first language acquisition and is based on the same grammar. In cognitive model 2, second language acquisition differs from first language acquisition and involves the construction of a partly different grammar. Our results suggest that the second scenario may be cognitively more plausible than the first one. Furthermore, our models explain why second language learners of Italian perform less native-like on overt pronouns than on null pronouns.
