我们报告了两个实验，更详细地探讨了冲突解决任务中的双语优势。特别地，我们关注的是在侧卫任务中，双语优势在总体反应时间上的起源。双语和单语参与者被要求在不同的任务版本下执行一个侧面任务。在实验1中，我们使用了两个低监控版本，其中大多数试验只有一种类型（一致性或不一致性）。在实验2中，我们使用了两个高监控版本，其中一致和不一致的试验分布更均匀。双语对整体反应时间的影响仅在高监测条件下存在。这些结果表明，当手头的任务需要大量的监控资源时，双语者的表现优于单语者。这一观察结果表明，双语可能会影响涉及执行控制的监测过程。(C) 2009 Elsevier B.V.版权所有
We report two experiments exploring more in detail the bilingual advantage in conflict resolution tasks. In particular, we focus on the origin of the bilingual advantage on overall reaction times in the flanker task. Bilingual and monolingual participants were asked to perform a flanker task under different task versions. In Experiment 1, we used two low-monitoring versions where most of the trials were of just one type (either congruent or incongruent). In Experiment 2, we used two high-monitoring versions where congruent and incongruent trials were more evenly distributed. An effect of bilingualism in overall reaction times was only present in the high-monitoring condition. These results reveal that when the task at hand recruits a good deal of monitoring resources, bilinguals outperform monolinguals. This observation suggests that bilingualism may affect the monitoring processes involved in executive control. (C) 2009 Elsevier B.V. All rights reserved.
