In this study, we present the results of an original experimental protocol designed to assess the performance in a pluralization task of 52 Italian children divided into two groups: 24 children with developmental dyslexia (mean age 10.0 years old) and 28 typically developing children (mean age 9.11 years old). Our task, inspired by Berko's Wug Test, had the aim of testing the subjects' ability to apply pluralization rules to nonwords in the morphologically complex context of Italian nominal inflection. Results demonstrate that dyslexics display poorer morphological skills in comparison to controls, showing lower accuracy in the task. Furthermore, the dissimilar performances reported by the subjects in the different conditions indicate that the ability to inflect nonwords depends on factors such as the rule's productivity, frequency, and opacity with respect to gender. Finally, the children's performance in this task was significantly related to their reading proficiency, and it could predict accuracy in word reading independently of phonological awareness and working memory.
在本研究中，我们展示了一项原创实验方案的结果，该方案旨在评估52名意大利儿童在复数化任务中的表现，这些儿童被分为两组：24名患有发育性阅读障碍的儿童（平均年龄10.0岁）和28名发育正常的儿童（平均年龄9.11岁）。我们的任务受伯克的“乌格测试”启发，旨在测试受试者在意大利名词屈折变化这一形态复杂的语境中，将复数化规则应用于非词的能力。结果表明，与对照组相比，阅读障碍儿童的形态学技能较差，在任务中表现出较低的准确性。此外，受试者在不同条件下表现出的差异表明，对非词进行屈折变化的能力取决于诸如规则的生成性、频率以及与性别的透明度等因素。最后，儿童在这项任务中的表现与他们的阅读熟练度显著相关，并且它可以独立于语音意识和工作记忆预测单词阅读的准确性。
