Subject pronoun expression (SPE) in Spanish has been widely studied across monolingual and bilingual varieties, showing a consistent effect of functional predictors. In recent papers, the role of the mechanical predictor priming, or perseveration, has been the source of debate. Additionally, little is known about the interaction of perseveration and significant functional predictors (e.g., grammatical person). In this paper, we expand on previous research by examining first-person singular (1sg) and third-person singular (3sg) data from sociolinguistic interviews with Spanish–English bilinguals from Florida to explore the possible difference in priming in deictic vs. referential subjects. The results from a mixed-effects variable rule analysis only offered clear evidence of priming in 1sg. We hypothesize that this result could be due to either surprisal (1sg overt pronominal subjects are rarer in the corpus that 3sg overt pronominal subjects) or to 3sg involving reference-tracking and perseveration only being evident in contexts where the subject form does not signal for pragmatic content.
