The goal of the present study was to investigate the time-course of suprasegmental information in visual word recognition. To this aim we measured event-related brain potentials (ERPs) during a simple lexical decision task in Italian. Two factors were manipulated: Stress dominance (the most frequent stress type) and stress neighborhood consistency (the proportion and number of existent words sharing orthographic ending and stress pattern). Participants were presented with target words either bearing dominant (on the penultimate syllable; 'graNIta,' 'seNIle,' slush, senile) or non-dominant stress (on the antepenultimate syllable; 'MISsile,' 'BIbita,' missile, drink), and either having a consistent (graNIta, MISsile) or an inconsistent stress neighborhood (seNIle, BIbita). Our results showed in the initial stages of processing an effect that we interpreted as an early orthographic marker of stress neighborhood in interaction with dominance. Later, from 250 ms after target onset, a marker of the lexical stress difference also emerged. The role of stress assignment in word recognition is discussed.
本研究的目的是调查视觉单词识别中音节以上信息的时间进程。为此，我们在意大利语的简单词汇判断任务中测量了事件相关脑电位（ERP）。我们操纵了两个因素：重音优势（最常见的重音类型）和重音邻域一致性（共享正字法结尾和重音模式的现存单词的比例和数量）。向参与者呈现的目标单词要么带有优势重音（在倒数第二个音节上；“graNIta”、“seNIle”、“slush”、“senile”），要么带有非优势重音（在倒数第三个音节上；“MISsile”、“BIbita”、“missile”、“drink”），并且要么具有一致的（graNIta、MISsile）要么具有不一致的重音邻域（seNIle、BIbita）。我们的结果表明，在处理的初始阶段，我们将一种效应解释为与优势相互作用的重音邻域的早期正字法标记。后来，在目标出现后250毫秒开始，词汇重音差异的标记也出现了。我们讨论了重音分配在单词识别中的作用。
