To stress or not to stress: what can Mandarin pronouns inform us of the accessibility of topic and focus?

Referents with a topical or focused status have been shown to be preferable antecedents in real-time resolution of pronouns. However, it remains unclear regarding whether topicality and focus compete for prominence when co-present in the same narrative, and if so, how differential prominence affects prosodic realization of a subsequent pronoun. Building upon the general understanding that stress on pronouns signals an unusual, less accessible interpretation, we take advantage of the conditional bi-clausal construction in conjunction with homophonic 3rd person pronouns in Chinese. We manipulated the information status of two referents that were introduced into a six-clause narrative in succession, specifically (i) Topic and (ii) Focus, and also (iii) the Reference of the Pronoun (either the first or second referent). Our acoustic analyses showed that pronouns were produced with higher F0s when the first referent was topicalized than when it was not topicalized under conditions where the second referent was focused. Pronouns referring back to the first referent were uttered longer when the referent was not topicalized than when it was topicalized. These results suggest accessibility statuses of referents vary dynamically in response to different prominence-lending cues, and these variations can be captured by the prosodic features of a following pronoun.
