In recent years, some studies have started to explore the impact of individual general executive functions (EFs) on bilingual language control. To our knowledge, few studies have systematically examined various components of EFs on different levels of language control in bilinguals. In two experiments, we investigated the effects of two components of IC on different levels of bilingual language control. The language-switching task was used to tap into language control at different levels. The Simon task was used to measure interference suppression in Experiment 1, and a go/no-go task was used to measure response inhibition in Experiment 2. Experiment 1 found that the smaller the Simon effect was, the larger the asymmetry of switch costs was. Experiment 2 found that the shorter the go response time was, the larger the global slowing effect was. Taken together, these findings suggest that the interference suppression component of domain-general IC facilitates local level language control, while response inhibition impacts global level language control in bilinguals.
近年来，一些研究开始探索个体一般执行功能（EFs）对双语语言控制的影响。据我们所知，很少有研究系统地考察了双语者在不同语言控制水平上的 EFs 的各种成分。在两项实验中，我们研究了 IC 的两个成分对双语语言控制不同水平的影响。语言转换任务用于挖掘不同水平的语言控制。Simon 任务用于在实验 1 中测量干扰抑制，而 go/no-go 任务用于在实验 2 中测量反应抑制。实验 1 发现 Simon 效应越小，转换代价的不对称性越大。实验 2 发现 go 反应时间越短，全局减速效应越大。总之，这些发现表明，领域一般性 IC 的干扰抑制成分有助于本地水平的语言控制，而反应抑制则影响双语者的全局水平语言控制。
