This study investigated whether the deployment of cognitive control was modulated by the intra-sentential code-switching types during comprehension. L1-dominant Chinese–English bilinguals were administered a self-paced reading task in two reading contexts – namely, alternation context and dense code-switching context. We assessed language switch cost and reversed language dominance effect in the self-paced reading task and examined how these language control measures related to domain-general inhibition and monitoring capacities. The results showed a larger switch cost asymmetry in alternation context compared to dense CS context. In addition, bilinguals’ inhibition skills were associated with second language (L2) switch cost in alternation context, while monitoring tended to predict the language dominance effect in dense code-switching context. These findings suggest that alternation context exerts high requirement to reactive inhibition while dense code-switching context tends to induce proactive monitoring during comprehension. We conclude that intra-sentential code-switching types trigger different aspects of cognitive control during comprehension.

本研究调查了在理解过程中认知控制的部署是否受到句内语码转换类型的调节。L1 主导的汉英双语者在两种阅读情境中执行自定进度的阅读任务——即交替语境和密集语码转换语境。我们评估了自定进度阅读任务中的语言转换成本和反向语言优势效应，并研究了这些语言控制措施如何与领域一般抑制和监控能力相关。结果显示，与密集 CS 上下文相比，交替上下文中的切换成本不对称性更大。此外，双语者的抑制技能与交替语境中的第二语言 (L2) 转换成本相关，而监控倾向于预测密集语码转换语境中的语言优势效应。这些发现表明，交替语境对反应性抑制有很高的要求，而密集的语码转换语境往往会在理解过程中引起主动监控。我们得出结论，句内语码转换类型在理解过程中触发认知控制的不同方面。
