Verbal morphology is a particularly vulnerable domain in the grammars of Spanish heritage speakers (HSs). Among the most frequently studied phenomena is mood selection, identified as a pervasive locus of variability that affects the production of subjunctive more prominently. The present article explores this area of research by examining the effects of mood selection type on HSs’ subjunctive use. In contrast with previous studies, this investigation controls for propositional modality, focusing its analyses on instances of obligatory and variable subjunctive selection within deontic predicates. Results from a production task revealed that, despite the presence of between-group differences driven by participants’ levels of proficiency, type of selection did not significantly modulate their rates of subjunctive use. These findings challenge previous claims about the extent to which this factor affects Spanish HSs’ performance, and highlight the importance of considering propositional modality when examining the acquisition of mood.

重新审视情绪选择类型在西班牙传统使用者虚拟语气产生中的作用

语言形态是西班牙传统使用者 (HS) 语法中特别脆弱的领域。最常研究的现象之一是情绪选择，它被认为是一种普遍存在的变异基因，它更显着地影响虚拟语气的产生。本文通过检查情绪选择类型对 HSs 虚拟语气使用的影响来探索这一研究领域。与之前的研究相比，本研究控制了命题模态，将其分析重点放在道义谓语中强制性和可变虚拟语气选择的实例上。生产任务的结果显示，尽管参与者的熟练程度导致组间差异存在，但选择类型并未显着调节他们的虚拟语气使用率。
