Structural priming from simple arithmetic to Chinese ambiguous structures: evidence from eye movement

This article explores the domain generality of hierarchical representation between linguistic and mathematical cognition by adopting the structural priming paradigm in an eye-tracking reading experiment. The experiment investigated whether simple arithmetic equations with high (e.g., (7 + 2) × 3 + 1)- or low (e.g., 7 + 2 × 3 + 1)- attachment influence language users' interpretation of Chinese ambiguous structures (NP₁ + He + NP₂ + De + NP₃; Quantifier + NP₁ + De + NP₂; NP₁ + Kan/WangZhe + NP₂ + AP). On the one hand, behavioral results showed that high-attachment primes led to more high-attachment interpretation, while low-attachment primes led to more low-attachment interpretation. On the other hand, the eye movement data indicated that structural priming was of great help to reduce dwell time on the ambiguous structure. There were structural priming effects from simple arithmetic to three different structures in Chinese, which provided new evidence on the cross-domain priming from simple arithmetic to language. Besides attachment priming effect at global level, online sentence integration at local level was found to be structure-dependent by some differences in eye movement measures. Our results have provided some evidence for the Representational Account.
