Executive functions (EFs) have great impact on language control indexed by language switch costs during production-based language switching. Yet, how they influence language control during comprehension-based language switching between embodied first language (L1, Chinese) emotional words and less embodied second language (L2, English) emotional words is less understood. Employing an emotional priming paradigm, this study recruited Chinese-English bilinguals as participants, and used emotional faces and words as experimental materials to explore the effects of cool [i.e., inhibitory control ability, IC ability] and hot (i.e., emotional valence and emotional congruency) EFs on language switch costs (i.e., language control) during Chinese-English emotional word comprehension. The results showed larger language switch costs in the emotional congruent condition relative to emotional conflict condition, larger Chinese switch costs than English switch costs, and larger language switch costs for negative over positive emotional words in the emotional congruent condition. In addition, high-IC participants showed larger English switch costs for negative emotional words compared with low-IC participants. These results indicated that hot EF and the embodiment of language had an impact on both language control and the modulation of cool EF on language control, and that the components of hot EFs interacted and jointly affected language control during language switching.
执行功能（EFs）对基于产出的语言切换过程中以语言切换成本为指标的语言控制有很大影响。然而，它们如何在基于理解的母语（L1，中文）情感词和较少具身性的第二语言（L2，英文）情感词之间的语言切换过程中影响语言控制，目前还不太清楚。本研究采用情感启动范式，招募中英双语者作为参与者，并使用情感面孔和词语作为实验材料，以探究冷执行功能（即抑制控制能力，IC能力）和热执行功能（即情感效价和情感一致性）对中英情感词理解过程中语言切换成本（即语言控制）的影响。结果表明，相对于情感冲突条件，情感一致条件下的语言切换成本更大，中文切换成本大于英文切换成本，且在情感一致条件下，负面情感词的语言切换成本大于正面情感词。此外，高IC参与者在负面情感词上的英文切换成本高于低IC参与者。这些结果表明，热执行功能和语言的具身性对语言控制以及冷执行功能对语言控制的调节都有影响，并且热执行功能的各个成分相互作用，共同影响语言切换过程中的语言控制。
