【摘要】 采用ERP技术,通过使用改进的快速序列视觉呈现范式(rapid serial visual presentation,RSVP),探讨在中文句子阅读中,读者是否能从副中央凹处获取语义信息。实验中要求被试注视逐字呈现于屏幕中央的句子,与此同时在屏幕中央左侧2°视角处呈现前一个字(n-1),右侧2°视角处呈现后一个字(n+1)。操纵句子中的动词,使之与4-5个字后出现的目标名词形成语义连贯与语义违背两种条件。着重考察目标名词位于右侧时,不同语义条件下ERP的差异。值得注意的是,此时屏幕上呈现的信息完全相同(见例句),因而可以避免中央凹和副中央凹词汇信息差异所带来的影响。17名被试参加了实验,结果显示,在关键屏呈现300到500ms时间窗下,与语义连贯条件相比,语义违背条件下产生一个更大的负波。这一结果表明中文句子阅读中,副中央凹处的语义信息不仅能被提取,而且可以即时参与到句义整合的过程中去。更多还原

【Abstract】 An ERP paradigm using rapid serial visual presentation(RSVP) with flankers was used in this study to explore the semantic parafoveal processing in reading Chinese.Seventeen participants’ event-related brain potentials(ERPs) were recorded as they read sentences presented character by character at fixation,flanked 2°bilaterally by the preceding character(n-1) on the left and the next character(n+1) on the right.Each sentence contained a verb that was either congruent or incongruent with the target single-character noun that appeared 4 or 5 characters after the verb.Importantly,the critical trials(i.e.,those containing the target noun as the right flanker) were the same across the congruent and incongruent conditions(see examples below).A larger negativity was found between 300 and 500ms when the right flanker was a contextually incongruent target noun than when it was a contextually congruent noun,indicating that semantic information was not only extracted from a parafoveal word,it was quickly and incrementally integrated with the evolving sentence representation in reading Chinese.更多还原
