我们研究了双语者在实时理解过程中整合语码转换（涉及解决冲突的语言表征）是否会调节认知控制机制的部署。在当前的实验中，西班牙语-英语双语者（N = 48）完成了一个跨任务冲突适应范式，测试阅读语码转换句子是否会触发认知控制参与，从而立即影响随后的侧翼试验中的表现。我们观察到，在增量处理句子的同时，检测语码转换（与阅读不包含语码转换的句子相反）有助于随后的冲突解决。面对跨语言冲突和随后的行为调整之间的这种时间上的相互依赖性表明，在在线理解过程中整合语码转换可能会招募领域通用的认知控制程序。我们建议，这种控制机制可以动员起来解决在实时解析代码转换输入期间跨语言出现的竞争表示之间的问题。总的来说，这些发现为双语的语言处理需求时时刻刻调节认知控制表现提供了新的见解。
We investigated whether bilinguals' integration of a code-switch during real-time comprehension, which involves resolving among conflicting linguistic representations, modulates the deployment of cognitive-control mechanisms. In the current experiment, Spanish-English bilinguals (N = 48) completed a cross-task conflict-adaptation paradigm that tested whether reading code-switched sentences triggers cognitive-control engagement that immediately influences performance on an ensuing Flanker trial. We observed that, while incrementally processing sentences, detecting a code-switch (as opposed to reading sentences that did not contain a code-switch) assisted subsequent conflict resolution. Such temporal interdependence between confronting cross-linguistic conflict and ensuing adjustments in behavior indicates that integrating a code-switch during online comprehension may recruit domain-general cognitive-control procedures. We propose that such control mechanisms mobilize to resolve among competing representations that arise across languages during real-time parsing of code-switched input. Overall, the findings provide novel insight into what language-processing demands of bilingualism regulate cognitive-control performance moment by moment.
