双语者在言语产生过程中持续控制两种语言的需要可能会对他们的注意网络产生普遍影响。为了探索这个问题，我们比较了双语者和单语者在Fan等人开发的注意网络任务（ANT）中的表现[Fan，J.，McCandliss，B.D. Sommer，T.，Raz，A.，Posner，M. I.（2002年）的报告。测试注意力网络的效率和独立性。Journal of Cognitive Neuroscience，14，340-347].这项任务应该利用三种不同的注意力网络：警觉，定向和执行控制。结果显示，双语参与者不仅在执行任务时更快，而且在警觉和执行控制网络中也更有效。特别是，双语者更容易受到提示线索的帮助，也更善于解决冲突的信息。此外，双语者，经历了减少转换成本之间的不同类型的试验相比，单语。这些结果表明，双语能力的影响，在实现有效的注意力机制的年轻人，应该是在他们的注意力能力的高峰。(c)2007年由Elsevier B.

The need of bilinguals to continuously control two languages during speech production may exert general effects on their attentional networks. To explore this issue we compared the performance of bilinguals and monolinguals in the attentional network task (ANT) developed by Fan et al. [Fan, J., McCandliss, B.D. Sommer, T., Raz, A., Posner, M.I. (2002). Testing the efficiency and independence of attentional networks. Journal of Cognitive Neuroscience, 14, 340-347]. This task is supposed to tap into three different attentional networks: alerting, orienting and executive control. The results revealed that bilingual participants were not only faster in performing the task, but also more efficient in the alerting and executive control networks. In particular, bilinguals were aided more by the presentation of an alerting cue, and were also better at resolving conflicting information. Furthermore, bilinguals, experienced a reduced switching cost between the different type of trials compared to monolinguals. These results show that bilingualism exerts an influence in the attainment of efficient attentional mechanisms by young adults that are supposed to be at the peak of their attentional capabilities.
