In producing linguistic variation, language users display a tendency to reuse the same variant. This paper compares the empirical properties of different types of repetitiveness in a single case study: locative variation in Chengdu Mandarin. Using conversational data from sociolinguistic interviews, we ask whether within-speaker repetitiveness (persistence) and cross-speaker repetitiveness (convergence) behave similarly with respect to (1) their sensitivity to the linguistic similarity of the prime and target, and (2) their tendency to decline with greater temporal distance between the prime and target. Our results suggest that intraspeaker persistence and interspeaker convergence behave similarly in both respects. We therefore propose that repetitiveness has a common underlying mechanism within and across speakers and encourage future work aimed at testing this hypothesis across other variables and varieties.
