An abundance of recent empirical data suggest that repeatedly allocating visual attention to task-relevant and/or reward-predicting features in the visual world engenders an attentional bias for these frequently attended stimuli, even when they become task irrelevant and no longer predict reward. In short, attentional selection in the past hinders voluntary control of attention in the present. But do such enduring attentional biases rely on a history of voluntary, goal-directed attentional selection, or can they be generated through involuntary, effortless attentional allocation? An abrupt visual onset triggers such a reflexive allocation of covert spatial attention to its location in the visual field, automatically modulating numerous aspects of visual perception. In this Registered Report, we asked whether a selection history that has been reflexively and involuntarily derived (i.e., through abrupt-onset cueing) also interferes with goal-directed attentional control, even in the complete absence of exogenous cues. To build spatially distinct histories of exogenous selection, we presented abrupt-onset cues twice as often at one of two task locations, and as expected, these cues reflexively modulated visual processing: task accuracy increased, and response times (RTs) decreased, when the cue appeared near the target's location, relative to that of the distractor. Upon removal of these cues, however, we found no evidence that exogenous selection history modulated task performance: task accuracy and RTs at the previously most-cued and previously least-cued sides were statistically indistinguishable. Thus, unlike voluntarily directed attention, involuntary attentional allocation may not be sufficient to engender historically contingent selection biases.
大量近期的实证数据表明,反复将视觉注意力分配到视觉世界中与任务相关和/或奖励预测的特征上,会导致对这些经常被注意的刺激产生注意力偏向,即使它们变得与任务无关且不再预测奖励。简而言之,过去的注意力选择会阻碍当前对注意力的自愿控制。但是,这种持久的注意力偏差是否依赖于自愿的、有目标导向的注意力选择的历史,或者它们是否可以通过无意识的、不费力气的注意力分配来产生?突然的视觉出现会引发这种对其在视野中位置的隐蔽空间注意力的反射性分配,自动调节视觉感知的众多方面。在本注册报告中,我们询问了一种通过反射和无意识的方式获得的选择历史(即通过突然出现的线索)是否也会干扰有目标导向的注意力控制,即使在外源性线索完全不存在的情况下也是如此。为了建立外源性选择的空间上不同的历史,我们两次更频繁地在两个任务位置之一呈现突然出现的线索,并且正如预期的那样,这些线索会反射性地调节视觉处理:与分心物相比,当线索出现在目标位置附近时,任务准确性提高,反应时间(RT)降低。然而,当去除这些线索时,我们没有发现外源性选择历史会调节任务表现的证据:以前最受提示和以前最少受提示的侧面的任务准确性和 RT 没有统计学上的区别。因此,与自愿引导的注意力不同,无意识的注意力分配可能不足以产生历史相关的选择偏差。
