Null subject acquisition in L2 Chinese speakers: a case study on English L1 speakers

Abstract

Abstract This article investigates the acquisition of null subjects (henceforth NSs) in (radical pro-drop) Chinese by learners whose native language is (non-pro-drop) English – henceforth ELs – working within the ‘topic chain’ information-structural approach. Our main goal is to verify whether a learner’s proficiency level can have an impact on the interpretation and acceptability of embedded NSs when more than one head is proposed for the relevant topic chain in different structural contexts (i.e., complements of bridge and factive verbs). The results of a pilot experimental test suggest that the requirement for a minimal overt link (MOLC) in the relevant chain plays an important role for ELs with a lower proficiency level. Conversely, MOLC restrictions do not affect ELs with a higher proficiency. Furthermore, the results show that ELs can correctly distinguish between complements of bridge and factive verbs already at an HSK 3 level. As for interpretation, results suggest that contextual information cannot supersede structural constraints for ELs. However, since a clash with contextual information seems to not affect acceptability for ELs, contrary to Chinese Native Speakers, we propose that even HSK 5 students have not fully acquired the competence for managing NSs in a radical language such as Chinese.
