Sociolinguistic Competence by L2 Chinese Learners Through the Lens of Null Object Use

Using the analytical tool Rbrul, this study explores the object expression variations in the speech of twenty CSL (Chinese as a Second Language) learners whose first languages (L1) were English, Russian, Korean, and Japanese, and compares them to native speaker (NS) patterns. Multivariate analysis revealed that the learner patterns closely resembled NSs’ in most dimensions explored, except the learners tended to overuse overt pronouns and underuse null forms. For both CSL learners and NSs, the general patterns in object use were as follows: (1) animate objects tended to favor overt objects, while inanimate objects favored null forms, (2) switch in referents favored overt forms, while no referent change favored null, (3) specific referents favored null forms, whereas nonspecific referents favored overt expressions, and (4) conversational contexts favored null forms, but elicited narratives favored explicit forms. As for the patterns specific to learners, the findings were as follows: (1) among the four L1s included in the analysis, Japanese and Russian speakers tended to use null objects more than Korean and English speakers, (2) a stay in China of one, two, or four years tended to favor null forms, but a three-year stay favored explicit forms, and (3) high-intermediate learners tended to use null forms more frequently than advanced learners. These results indicated that learners successfully acquired null object use patterns in spoken Chinese, but they still required further development in understanding the nuances between overt object forms and null object use to enhance their sociolinguistic competence.
