Cognitive control enables humans to behave guided by their current goals and intentions. Cognitive control in one task generally suffers when humans try to engage in another task on top. However, we discovered an additional task that supports conflict resolution. In two experiments, participants performed a spatial cognitive control task. For different blocks of trials, they either received no instruction regarding eye movements or were asked to maintain the eyes fixated on a stimulus. The additional eye fixation task did not reduce task performance, but selectively ameliorated the adverse effects of cognitive conflicts on reaction times (Experiment 1). Likewise, in urgent situations, the additional task reduced performance impairments due to stimulus-driven processing overpowering cognitive control (Experiment 2). These findings suggest that maintaining eye fixation locks attentional resources that would otherwise induce spatial cognitive conflicts. This reveals an attentional disinhibition that boosts goal-directed action by relieving pressure from cognitive control.
认知控制使人类能够按照当前的目标和意图行事。当人们试图同时进行另一项任务时，一项任务中的认知控制通常会受到影响。然而，我们发现了一项有助于解决冲突的额外任务。在两项实验中，参与者执行了一项空间认知控制任务。在不同的试验块中，他们要么没有收到关于眼球运动的指示，要么被要求保持眼睛注视一个刺激物。额外的眼球注视任务并没有降低任务表现，而是选择性地减轻了认知冲突对反应时间的不利影响（实验1）。同样，在紧急情况下，额外的任务减少了由于刺激驱动的处理压倒认知控制而导致的表现受损（实验2）。这些发现表明，保持眼球注视锁定了否则会引发空间认知冲突的注意力资源。这揭示了一种注意力去抑制，通过减轻认知控制的压力来促进目标导向的行动。
