Previous research has shown that syllables are important units in visual word recognition in Spanish. If they are treated as real phonological units, then other related phonological features such as lexical stress (syllable prominence) may also play a role in this process. At times, lexical stress is the only difference between minimal pairs in Spanish (e.g., sábana ‘sheet’ vs sabana ‘savannah’). These words are usually distinguished by an accent mark. This research examines whether lexical stress is used in visual word recognition and the role of the written accent mark in this process.

浅谈书面重音符号在西班牙语视觉词识别中的作用

先前的研究表明，音节是西班牙语视觉单词识别的重要单位。如果它们被视为真正的音系单位，那么其他相关的音系特征如词汇重音（音节突出）也可能在这个过程中发挥作用。有时，词汇重音是西班牙语中最小对之间的唯一区别（例如，sábana 'sheet' 与sabana 'savannah'）。这些词通常用重音符号来区分。本研究考察了词汇重音是否用于视觉单词识别以及书面重音符号在此过程中的作用。
