Abstract A recent approach to explaining the domain-general cognitive outcomes of bilingualism is to consider the role of disengagement of attention, rather than the engagement of focused attention or inhibition as is typical in most accounts. The present study pursues this approach by examining the neurophysiological changes associated with disengagement of attention in young adults performing an inhibition of return (IOR) paradigm while EEG was recorded. Participants were drawn from a diverse community and varied widely in their bilingual experience. There were three main findings. First, dividing the sample into dichotomous groups based on language proficiency did not lead to reliable group differences on the task. Second, using instead continuous measures of bilingualism across the sample indicated that greater bilingual experience and proficiency were associated with the magnitude of the IOR effect, with more bilingual individuals showing larger and earlier IOR effects. Finally, a network of processes that are temporally and spatially distinct were found to work together to produce facilitation, disengagement of attention, and inhibition of return. These findings contribute to debates regarding the electrophysiological correlates of the IOR effect and provide additional evidence for how bilingualism affects domain-general cognition.

双语会改变整个头皮的注意力网络的脱离：对 IOR 范式的多变量 ERP 调查

摘要：最近解释双语的领域一般认知结果的一种方法是考虑脱离注意力的作用，而不是像大多数账户那样典型地考虑集中注意力或抑制的作用。本研究通过检查与记录脑电图时执行返回抑制 (IOR) 范式的年轻人的注意力脱离相关的神经生理学变化来追求这种方法。参与者来自多元化的社区，他们的双语体验差异很大。有三个主要发现。首先，根据语言能力将样本分成二分组并没有导致任务上可靠的组差异。第二，相反，在样本中使用双语连续测量表明，双语经验和熟练程度与 IOR 效应的幅度相关，更多的双语个体表现出更大和更早的 IOR 效应。最后，发现一个在时间和空间上截然不同的过程网络共同作用以产生促进、分散注意力和抑制返回。这些发现有助于关于 IOR 效应的电生理相关性的辩论，并为双语如何影响域一般认知提供额外的证据。一个在时间和空间上截然不同的过程网络被发现协同工作以产生促进、分散注意力和抑制返回。这些发现有助于关于 IOR 效应的电生理相关性的辩论，并为双语如何影响域一般认知提供额外的证据。一个在时间和空间上截然不同的过程网络被发现协同工作以产生促进、分散注意力和抑制返回。这些发现有助于关于 IOR 效应的电生理相关性的辩论，并为双语如何影响域一般认知提供额外的证据。
