This study assessed whether two well known effects associated with cognitive control, conflict adaptation (the Gratton effect) and conflict context (proportion congruent effects), reflect a single common or separate control systems. To test this we examined if these two effects generalized from one kind of conflict to another by using a combined-conflict paradigm (involving the Simon and Spatial Stroop tasks) and manipulating the proportion of congruent to incongruent trials for one conflict (Simon) but not the other (Spatial Stroop). We found that conflict adaptation effects did not generalize, but the effect of conflict context did. This contrasting pattern of results strongly suggests the existence of two separate attentional control systems, one transient and responsible of online regulation of performance (conflict adaptation), the other sustained and responsible for conflict context effects.
本研究旨在评估与认知控制相关的两种众所周知的效应，即冲突适应（Gratton 效应）和冲突情境（比例一致效应），是否反映了单一的共同或独立的控制系统。为了检验这一点，我们通过使用联合冲突范式（涉及 Simon 和空间斯特鲁普任务）并操纵一种冲突（Simon）的一致和不一致试验的比例但不操纵另一种冲突（空间斯特鲁普）来检验这两种效应是否从一种冲突泛化到另一种冲突。我们发现，冲突适应效应没有泛化，但冲突情境效应却有。这种对比鲜明的结果模式强烈表明存在两个独立的注意控制系统，一个是瞬态的，负责在线调节性能（冲突适应），另一个是持续的，负责冲突情境效应。
