即使刺激的位置不相关，在空间一致的刺激-反应关联中，对侧化刺激的手动反应要比在空间不一致的关联中更快。然而，这种效应随着反应时间的增加而减弱。最近的数据表明，这种下降反映了在线的、审判内的行政控制。本研究旨在通过分析参与反应执行的肌肉的肌电图活动来验证这一假设。我们专注于特定的试验，在这些试验中，与错误反应相关的肌肉的激活先于正确反应的执行。一项序列效应分析以及对反应时间分布的分析显示，在这种双激活试验之后，执行控制得到了加强。此外，与没有错误激活的试验相比，与这些试验相关的反应时间的分布分析显示，在线，在试验中执行控制的变化。对不相关刺激位置影响的迟动轨迹的争论也被提供。这些结果讨论了目前的模型的认知控制。
Manual responses to lateralized stimuli are faster for spatially congruent stimulus-response associations than for incongruent associations, even if the stimulus location is irrelevant. This effect, however, decreases as reaction time increases. Recent data suggest that such a decrease reflects online, within-trial executive control. The present study was aimed at testing this hypothesis by analyzing the electromyographic activity of muscles involved in response execution. We focused on the particular trials in which an activation of the muscle involved to the incorrect response preceded the execution of the correct response. A sequential effect analysis, along with an analysis of the reaction time distributions, revealed that after such dual-activation trials, executive control was reinforced. In addition, a distribution analysis of the reaction times associated with such trials compared to the trials without incorrect activation, revealed online, within-trial changes in executive control. Arguments against a late motor locus of the effect of the irrelevant stimulus location are also provided. These results are discussed in terms of current models of cognitive control.
