Abstract
Because of limited language input, different dominant languages, and learners’ differing backgrounds, the acquisition of heritage languages is distinguished from the acquisition of L1 and L2. Few studies of Chinese as a Heritage Language (CHL) have explored whether students can acquire native-like sociolinguistic competence and language-specific variables with educational input. Based on a sociolinguistic variationist perspective, this study investigates the acquisition of variation between null and overt subject personal pronouns (SPP s) by heritage learners in an undergraduate-level Mandarin program. A total of 11,970 tokens were collected through classroom observation, sociolinguistic interviews, and narratives. Measuring mixed-effects logistic regression with Rbrul (Johnson, 2009), results show that the overall usage pattern of SPP s by CHL students largely resembled that in the input provided by the language program. Results also demonstrate that linguistic constraints including coreference, person and number, and verb type, and social factors such as discourse context, first languages, course level, and age of arrival had a significant effect on SPP expression by CHL learners. Implications for CHL development and variationist studies in heritage languages are discussed.
