Abstract

Attentional capture by irrelevant distractors can impede people's performance, making the cognitive control of attentional capture an important mechanism. The methodology applied in previous studies provided participants with foreknowledge of the upcoming distractor to investigate the top-down inhibitory control mechanism. However, these findings are mixed. This study further examined whether precueing the spatial location of the color-singleton or onset-singleton distractors in the upcoming search array can reduce related interference. Experiments 1A and 2A demonstrated the benefit of precueing the spatial location of the color-singleton distractors. Contrastingly, the overall performance of Experiments 1B, 1C, and 2B did not reveal a benefit of precueing when onset-singleton distractors were presented. In addition, analyses of vincentized cumulative reaction time distributions, the spatial distribution of the suppression effect in each experiment, and memory probes in Experiments 2A and 2B suggest that the effects of distractor precueing may involve the coordination of proactive and reactive control mechanisms.

单一干扰物的自上而下抑制控制:干扰物类型和时间过程。
不相关干扰物的注意力捕获会阻碍人们的表现,这使得注意力捕获的认知控制成为一个重要的机制。先前研究采用的方法为被试提供了对即将到来的干扰物的预知,以研究自上而下的抑制控制机制。然而,这些发现好坏参半。本研究进一步考察了在即将到来的搜索阵列中预先确定颜色-单元素或起始-单元素干扰物的空间位置是否可以减少相关干扰。实验1A和2A证明了预先确定颜色单一干扰物的空间位置的好处。相比之下,实验1B、1C和2B的整体表现并没有显示当出现单一干扰物时,预防的好处。此外,实验2A和实验2B的累积反应时间分布、抑制效应的空间分布以及记忆探针的分析表明,干扰物预防的作用可能涉及主动控制机制和反应控制机制的协调。(PsycInfo Database Record (c) 2025 APA,版权所有)。
