我们探索了双语语言控制后效的时间过程，以阐明语言控制的范围（局部与全局）以及语言控制的实施方式（L1抑制或L2过度激活）。高水平的双语者在三个区块中命名物体，首先在他们的L1中，然后在他们的L2中，然后再在他们的L1中（反之亦然），同时记录事件相关脑电位（ERP）。从行为上看，我们发现只有L1受到L2中先前命名的阻碍。在ERP中，我们没有观察到抑制效应的N2成分的时间窗。然而，当前一种语言放慢了对后一种语言的命名速度时，P2成分表现出更多的正向偏转。P2平均振幅预测命名laviration，而N2没有。我们的结论是，在高熟练双语者的P2组件是语言控制机制的标记，而不是抑制，这是全球性的。(C)2013爱思唯尔有限公司保留所有权利。
We explored the temporal course of bilingual language control after-effects to shed light on the scope of language control (local vs. global) and on the way in which language control is implemented (L1 inhibition or L2 over-activation). High-proficient bilinguals named objects across three blocks, first in their L1, then in their L2, and then again in their L1 (and conversely) while event-related brain potentials (ERPs) were recorded. Behaviorally we found only the L1 as being hindered by previous naming in the L2. In the ERPs we did not observe inhibitory effects in the N2 component time-window. However, the P2 component showed more positive-going deflections when the previous language slowed down naming latencies of the successive language. The P2 mean amplitude predicted naming latencies whereas the N2 did not. We conclude that in high-proficient bilinguals the P2 component is the marker of language control mechanisms other than inhibition, which are applied globally. (C) 2013 Elsevier Ltd.
