为验证中文的N400字体效应,探索字体和使用频率在语义提取上的交互作用,以大学生为被试,采用事件相关电位(ERP)技术和真假词判断任务,操控双字词的字体和频率,记录被试对真假双字词的判断反应和ERP,结果表明:行楷体比宋体引发更负的N400波幅,且在低频真词上更显著,另外在真词条件下,频率和字体在N400上存在交互作用.认为字形在语义通达中起到重要作用,支持中文形-义加工说和交互激活模型,不支持多阶段激活模型.
To verify the N400 font effect in Chinese, explore the interaction between fonts and the frequency of semantic extraction. Using college students as test subjects, using incident-related potentials (ERP) and true-false-word judgment tasks, the fonts and frequencies of double-word control , The participants recorded the judgments and ERPs of true and false double words. The results showed that: Times of italicized italics triggered a more negative N400 amplitude than that of Times New Roman, and more pronounced in the low-frequency truth words. In addition, There is an interaction on the N400, and it is believed that glyphs play an important role in semantic accessibility and support for Chinese-type processing and interaction activation models, and multi-stage activation models are not supported.
