The study investigates whether Italian verbal inflectional morphology is associated with inhibitory control skills after controlling for receptive vocabulary and verbal working memory. A sample of Italian preschoolers aged 4;0 to 6;0 was assessed using a standardized inhibitory control task tapping two different inhibitory skills (response inhibition and interference suppression), and a morphological task requiring simple and complex inflections of verbs. The hierarchical multiple regression analyses showed that working memory and the interference suppression scores were significantly associated with complex inflections but not with simple inflections of the verbs.

该研究在控制接受性词汇和言语工作记忆后调查了意大利语言语屈折形态是否与抑制控制技能相关。使用标准化抑制控制任务对 4;0 至 6;0 岁的意大利学龄前儿童样本进行评估，该任务利用两种不同的抑制技能（反应抑制和干扰抑制），以及需要简单和复杂动词变形的形态学任务。层次多元回归分析表明，工作记忆和干扰抑制分数与复杂的词形变化显着相关，但与动词的简单词形变化无关。
