【摘要】 本研究采用ERP技术考察中国二语学习者的英语增元结构加工机制。研究发现，动词典型性影响英语增元结构加工，句法-语义错配认知冲突受动词与结构联结程度调节;英语增元结构中非常规论元的N400效应显著大于介词与格结构的常规论元，表明二语学习者为非常规论元分派题元角色时产生加工困难。本研究对基于句法-语义接口的二语加工研究具有启发意义。更多还原

【Abstract】 This study employs event-related potentials(ERPs) to investigate the neurocognitive mechanisms underlying Chinese second language(L2) learners’ processing of English applicative constructions. The results reveal that verb typicality modulates the processing of English applicative constructions,with the cognitive conflict arising from the syntax-semantics mismatch being mediated by the strength of verb-construction association. Moreover,the noncore argument in English applicative constructions elicits a significantly larger N400 compared to the core argument in prepositional dative constructions,indicating that L2 learners experience greater processing difficulty when assigning thematic roles to the non-core argument. These findings offer implications for advancing research on L2processing at the syntax-semantics interface.更多还原
