当在两个任务之间快速切换时,二价刺激可能意外地触发先前执行的、因此仍被激活的反应。最近,有人提出,行为反应-重复效应反映了反应抑制,从而降低了这种错误反应重复的风险。本研究使用偏侧就绪电位(LRP)研究了这一抑制过程的神经关联。在三个实验中,我们证明了在准备阶段出现的反应-转换偏向与任务顺序无关(实验1),与任务准备有关(实验2),只有在任务转换条件下才存在(实验3)。这些结果表明,这种偏差反映了一种自适应地调节反应准备的控制过程。
When rapidly switching between two tasks, bivalent stimuli can accidentally trigger the previously executed and therefore still activated response. Recently, it has been suggested that behavioral response-repetition effects reflect response inhibition that reduces the risk of such erroneous response repetitions. The present study investigated neural correlates of this inhibition process using lateralized readiness potentials (LRP). In three experiments, we demonstrate a response-switch bias emerging during the preparatory interval which is independent of task sequence (Experiment 1), which is linked to task preparation (Experiment 2), and which is present only under task-switching conditions (Experiment 3). These results suggest that the bias reflects a control process that adaptively regulates response preparedness.
