Abstract This study investigated the predictive use of dative verb constraints in Mandarin among home-country-raised native speakers and classroom learners (including both sequential L2 learners and heritage speakers). In a visual world eye-tracking experiment, participants made anticipatory looks to the upcoming argument (recipient versus theme) following categorical restrictions of non-alternating verbs and gradient bias of alternating verbs before the acoustic onset of the disambiguating noun. Crucially, no delay or reduction in the prediction effects was observed among L2 learners and heritage speakers in comparison with home-country-raised native speakers. Mandarin proficiency and dominant language (English versus other) did not modulate prediction effects among classroom learners. These findings provide direct support for the assumption of error-driven learning accounts of the dative alternation, that is, language users actively predict upcoming arguments based on verb information during real-time sentence processing. 

Abstract This study investigated whether structural priming, as a reflection of error-driven learning mechanisms, could facilitate second language (L2) learning of the dative alternation in Mandarin. We sought evidence of learning from both priming and acceptability judgment data. Participants were 25 native speakers and 41 classroom learners (CLs). After a priming session in which participants predicted and then saw what a virtual partner had written to describe pictures (prime trials, with only acceptable verb-dative pairings), CLs showed increased production of these acceptable pairings and increased acceptability ratings for them. The observation of such longer-term priming effects beyond the priming phase, together with an inverse frequency effect of priming observed among the CLs, aligns well with error-driven learning accounts. However, we did not find evidence for statistical preemption, in that participants did not decrease ratings for unacceptable pairings as a result of exposure to their competing alternatives.
