Bilingual children’s online processing of relative clauses

Abstract

Abstract Long-distance dependencies such as relative clauses (RCs) are known to be vulnerable in heritage grammars (e.g., Montrul, 2008). Previous studies in RC comprehension have shown that heritage language (HL) children show similar comprehension to monolingual children (Jia & Paradis, 2020), while differential performance has also been found (Kidd et al., 2015). The present study investigates 11–13-year-old monolingual and German-dominant HL children’s real-time parsing strategies in subject relative clause (SRC) and object relative clause (ORC) processing in Greek. We conducted a self-paced listening task in Greek in which we manipulated the type of RC (subject vs. object), and the RC internal word order (canonical vs. scrambled). Our analyses revealed no significant group differences between HL and monolingual children. Both groups of children processed SRCs faster than ORCs on the critical RC verb segment. We also examined if case-marked pre-verbal NPs would facilitate the processing of ORC structures. Although children processed pre-verbal faster than post-verbal NPs, ORC structures with pre-verbal NPs received the lowest scores in the grammaticality judgment task. We discuss these findings on the grounds of Relativized Minimality (Friedmann et al., 2009) and Fodor and Inoue’s (2000) Diagnosis and Repair Model.
