“…Apart from place of origin, we identified 9 other potential demographic and speaker-specific variables: age, gender, language attitude, target norm, L1 Mandarin rhoticity, speech style, media exposure, additional language(s) spoken by the informants, and experience abroad and tested whether they determine postvocalic /r/ presence in Chinese English. It should be noted that since age and gender differences in rhoticity may be more directly related to the sociohistorical sphere surrounding ESL contexts and the sociolinguistic identities and ideologies therein, these factors are more likely to play a role in Outer Circle Englishes (e.g., Chand, 2010 for Indian English, Hartmann and Zerbian 2010 for Black South African English) than in Expanding Circle Englishes. 5 However, we expected speech style to be a more conspicuous predictor of /r/ presence in Chinese English especially given that both studies on Korean English (Kang, 2013) and Yunnan English (Sundkvist and Gao, 2016) have shown that different speech contexts would trigger various levels of attention, thus resulting in variation in rhoticity in Expanding Circle Englishes.…”
