Observers can adopt attentional control settings that regulate how their attention is drawn to salient stimuli in the environment. Do observers choose their attentional control settings voluntarily, or are they primed in a bottom-up manner based on the stimuli that the observer has recently attended and responded to (i.e., target-selection history)? In the present experiment, we tested these two accounts using a long-term memory attentional control settings paradigm, in which participants memorized images of 18 common visual objects, and then searched for those objects in a spatial blink task. Unbeknownst to participants, we manipulated priming by dividing the set of target objects into two subsets: nine objects appeared frequently as targets in the spatial blink task (frequently primed objects), and nine infrequently (infrequently primed objects). We assessed attentional capture by presenting these objects as distractors in the spatial blink task and measuring their effect on task accuracy. We found that both subsets of objects captured attention more than non-studied objects, and frequently primed objects did not capture attention more than infrequently primed objects. Moreover, a follow-up analysis revealed that all studied objects captured attention, even before those objects had appeared as targets in the spatial blink task. These findings suggest that priming through target-selection history plays little-to-no role in long-term memory attentional control settings. Rather, these findings align with a growing body of evidence that attentional control settings are primarily implemented through voluntary control.
观察者可以采用注意力控制设置,来调节他们的注意力如何被环境中的显著刺激所吸引。观察者是自愿选择他们的注意力控制设置,还是基于观察者最近关注和响应的刺激(即目标选择历史)以自下而上的方式被启动呢?在本实验中,我们使用长期记忆注意力控制设置范式对这两种说法进行了测试,在该范式中,参与者记住了18个常见视觉对象的图像,然后在空间闪烁任务中搜索这些对象。参与者并不知道,我们通过将目标对象集分为两个子集来操纵启动:九个对象在空间闪烁任务中经常作为目标出现(频繁启动对象),九个对象则很少出现(不频繁启动对象)。我们通过在空间闪烁任务中将这些对象作为干扰项呈现,并测量它们对任务准确性的影响,来评估注意力捕获情况。我们发现,这两个对象子集比未研究的对象更能吸引注意力,并且频繁启动对象并不比不频繁启动对象更能吸引注意力。此外,后续分析表明,所有研究过的对象都能吸引注意力,甚至在这些对象在空间闪烁任务中作为目标出现之前。这些发现表明,通过目标选择历史进行的启动在长期记忆注意力控制设置中几乎没有作用。相反,这些发现与越来越多的证据一致,即注意力控制设置主要通过自愿控制来实现。
