In the present study stress diacritics were used to investigate the processing of stress information in lexical decision. We ran two experiments in Italian, a language in which stress position is not predictable by rule and only final stress – i.e., the less common pattern – is orthographically marked with a diacritic. In Experiment 1, a lexical decision task, two factors were manipulated: The stress pattern of words – antepenultimate (non dominant) and penultimate (dominant) – and the presence/absence of the diacritics, signalling the stress position. Participants were faster to categorize stimuli as words when they bear dominant than non dominant stress. However, the advantage disappeared when the diacritic was used. In Experiment 2, a same-different verification task was used in which participants had to decide if a referent word and a target were same (carota-CAROTA, /ka'rɔta/; tavolo-TAVOLO, /'tavolo/) or different. We compared two conditions requiring a "different" response, in which referent and target with dominant and non dominant stress were congruent (caròta-CAROTA; tàvolo-TAVOLO) or incongruent (càrota-CAROTA; tavòlo-TAVOLO) with the word’s stress. For words with dominant stress, “different” responses were faster in the incongruent condition than the congruent condition. This congruency effect was not observed for words with non-dominant stress pattern. Overall, the data suggest that stress information is based on lexical phonology, and the stress dominance effect has a lexical base in word recognition.

在本研究中，重音变音符号用于研究词汇决策中重音信息的处理。我们用意大利语进行了两个实验，在这种语言中，重音位置无法通过规则预测，只有最终重音（即不太常见的模式）用变音符号进行正字法标记。在实验 1 中，一个词汇决策任务，操纵了两个因素：单词的重音模式——倒数第二（非显性）和倒数第二（显性）——以及变音符号的存在/不存在，表明重音位置。参与者在承受主导压力时比非主导压力更快地将刺激归类为单词。然而，当使用变音符号时，优势就消失了。在实验 2 中，使用了相同不同的验证任务，参与者必须决定所指词和目标是相同的（carota-CAROTA，/ka'rɔta/；tavolo-TAVOLO，/'tavolo/）还是不同的。我们比较了两种需要“不同”反应的条件，其中具有显性和非显性重音的所指和目标与单词的重音一致 (caròta-CAROTA; tàvolo-TAVOLO) 或不一致 (càrota-CAROTA; tavòlo-TAVOLO)。对于具有显性重音的单词，不一致条件下的“不同”反应比一致条件下更快。对于具有非显性重音模式的单词，没有观察到这种一致性效应。总体而言，数据表明重音信息是基于词汇音系的，重音优势效应在单词识别中具有词汇基础。tavolo-TAVOLO, /'tavolo/) 或不同。我们比较了两种需要“不同”反应的条件，其中具有显性和非显性重音的所指和目标与单词的重音一致 (caròta-CAROTA; tàvolo-TAVOLO) 或不一致 (càrota-CAROTA; tavòlo-TAVOLO)。对于具有显性重音的单词，不一致条件下的“不同”反应比一致条件下更快。对于具有非显性重音模式的单词，没有观察到这种一致性效应。总体而言，数据表明重音信息是基于词汇音系的，重音优势效应在单词识别中具有词汇基础。tavolo-TAVOLO, /'tavolo/) 或不同。我们比较了两种需要“不同”反应的条件，其中具有显性和非显性重音的所指和目标与单词的重音一致 (caròta-CAROTA; tàvolo-TAVOLO) 或不一致 (càrota-CAROTA; tavòlo-TAVOLO)。对于具有显性重音的单词，不一致条件下的“不同”反应比一致条件下更快。对于具有非显性重音模式的单词，没有观察到这种一致性效应。总体而言，数据表明重音信息是基于词汇音系的，重音优势效应在单词识别中具有词汇基础。其中具有显性和非显性重音的所指和目标与单词的重音一致 (caròta-CAROTA; tàvolo-TAVOLO) 或不一致 (càrota-CAROTA; tavòlo-TAVOLO)。对于具有显性重音的单词，不一致条件下的“不同”反应比一致条件下更快。对于具有非显性重音模式的单词，没有观察到这种一致性效应。总体而言，数据表明重音信息是基于词汇音系的，重音优势效应在单词识别中具有词汇基础。其中具有显性和非显性重音的所指和目标与单词的重音一致 (caròta-CAROTA; tàvolo-TAVOLO) 或不一致 (càrota-CAROTA; tavòlo-TAVOLO)。对于具有显性重音的单词，不一致条件下的“不同”反应比一致条件下更快。对于具有非显性重音模式的单词，没有观察到这种一致性效应。总体而言，数据表明重音信息是基于词汇音系的，重音优势效应在单词识别中具有词汇基础。
