动词过去式“双系统”认知模型ERP研究

ERP Studies of Dual-system Cognitive Model of the Past Tense Verb Forms

动词过去式的规则和不规则形态变化为心理词汇研究提供独特视角。事件相关电位技术(ERP)为心理词汇的认知加工过程研究提供高精度测量手段。本文从母语和二语加工两个维度系统梳理动词过去式认知机制ERP研究的不同实验范式,重点讨论并解释相关特征波形成分。系列ERP实验结果都证明动词过去式心理表征分为心理词汇与心理语法两个系统,"双系统"认知模型具有广泛的认知生理机制。文章据此提出本领域研究目前存在的挑战和今后的研究方向。

The idiosyncratic mappings of regular and irregular morphological changes of the past tense verb forms provide a distinct per- spective for the study of mental lexicon. Event-related Potential （ERP） technique provides a high temporal resolution measure- ment of the cognitive processing of mental lexicon. Differentiating between first and second language processing, this paper re- views different paradigms of ERP experiments on the cognitive mechanisms of the past tense verb forms, with an emphasis on dis- cussing different ERP components. Results show that the past tense verb forms are mentally processed in two cognitive channels ： mental lexicon and mental grammar. This ＂Dual-system＂ cognitive model for the past tense verb forms is substantiated with physiological substrate. Based on the analyses, the paper discusses future challenges and research directions for the field.
