Language Variation and Perception: Subject Pronominal Expression in Native and Non-Native Mandarin Chinese

Subject pronoun expression (SPE) has been widely studied as a sociolinguistic variable across a range of languages. However, previous research has primarily focused on production, leaving the perception of subject pronouns largely unexplored. The perception of sociolinguistic variants not only reflects unconscious judgments towards linguistic features but also unveils the social meanings associated with these features. This study explores the perception of SPE in Mandarin by native and non-native listeners. 262 participants (185 native and 77 non-native) were recruited for Mandarin SPE perception tasks in which participants needed to rate the appropriate use of SPE in given contexts. Mixed-effects regression models reveal that native and non-native Mandarin listeners shared similar perception patterns of SPE. SPE rate serves as a significant structural constraint for both native and non-native perception. However, these two groups differ in that person of the subject and L2 experience play a key role in native perception, whereas non-native listeners demonstrated greater sensitivity to gender as a social factor. To what extent production and perception may interact is further discussed. This study contributes to the current understanding of sociolinguistics and second language acquisition by providing empirical evidence of SPE perception, adopting innovative approaches to examine variation perception, addressing the differences between native and non-native patterns of perceptual variation, and exploring the connection between variation production and perception.
