Recent findings from English and Russian have shown that grammatical category plays a key role in stress assignment. In these languages, some grammatical categories have a typical stress pattern and this information is used by readers. However, whether readers are sensitive to smaller distributional differences and other morpho-syntactic properties (e.g., gender, number, person) remains unclear. We addressed this issue in word and non-word reading in Italian, a language in which: (1) nouns and verbs differ in the proportion of words with a dominant stress pattern; (2) information specified by words sharing morpho-syntactic properties may contrast with other sources of information, such as stress neighborhood. Both aspects were addressed in two experiments in which context words were used to induce the desired morpho-syntactic properties. Experiment 1 showed that the relatively different proportions of stress patterns between grammatical categories do not affect stress processing in word reading. In contrast, Experiment 2 showed that information specified by words sharing morpho-syntactic properties outweighs stress neighborhood in non-word reading. Thus, while general information specified by grammatical categories may not be used by Italian readers, stress neighbors with morpho-syntactic properties congruent with those of the target stimulus have a primary role in stress assignment. These results underscore the importance of expanding investigations of stress assignment beyond single words, as current models of single-word reading seem unable to account for our results.
英语和俄语的最新研究结果表明，语法类别在重音分配中起着关键作用。在这些语言中，一些语法类别具有典型的重音模式，读者会利用这些信息。然而，读者是否对较小的分布差异和其他形态句法属性（如性、数、人称）敏感仍不清楚。我们在意大利语的单词和非单词阅读中解决了这个问题，意大利语具有以下特点：（1）名词和动词中具有主导重音模式的单词比例不同；（2）具有相同形态句法属性的单词所指定的信息可能与其他信息来源形成对比，如重音邻域。这两个方面在两个实验中得到了探讨，实验中使用上下文单词来诱导所需的形态句法属性。实验1表明，语法类别之间重音模式的相对不同比例不会影响单词阅读中的重音处理。相比之下，实验2表明，在非单词阅读中，具有相同形态句法属性的单词所指定的信息比重音邻域更重要。因此，虽然意大利语读者可能不会使用语法类别所指定的一般信息，但与目标刺激具有相同形态句法属性的重音邻域在重音分配中起主要作用。这些结果强调了将重音分配的研究扩展到单个单词之外的重要性，因为当前的单字阅读模型似乎无法解释我们的结果。
