While most research on attentional templates focuses on how attention can be guided toward targets, a growing body of research has been examining our ability to guide attention away from distractors using negative templates. A recent report showed larger reaction time benefits from negative templates during a difficult search task compared to an easy search task. However, it remains unclear what shifts in attentional processing led to these differences in reaction time benefits. In the current study, we tested the predictions of enhanced guidance and rapid rejection as potential explanations for the differential impact of negative templates based on search difficulty. In Experiment 1, we replicated the larger benefits from negative templates in a within-subjects design. In Experiment 2, we use eye tracking to measure the proportion of fixations directed towards target-colored distractors as an index of enhanced guidance and the dwell time on distractors as a measure of rapid rejection. We found more attentional guidance from negative templates in the difficult search condition. In addition, we found larger benefits of rapid rejection from negative templates in the difficult search condition. While we typically focus on templates as a way of guiding attention, these results highlight another key role played by attentional templates: rapid distractor rejection.
虽然大多数关于注意模板的研究都集中在注意力如何被引导到目标上,但越来越多的研究开始考察我们使用负模板将注意力从干扰物上转移的能力。最近的一份报告显示,在困难搜索任务中,与简单搜索任务相比,负模板在反应时间上有更大的优势。然而,目前尚不清楚注意力加工的哪些变化导致了反应时间优势的差异。在当前的研究中,我们根据搜索难度测试了增强引导和快速排斥作为负模板产生差异影响的潜在解释。在实验 1 中,我们在被试内设计中复制了负模板的更大优势。在实验 2 中,我们使用眼动追踪来测量注视朝向目标颜色干扰物的比例,作为增强引导的指标,以及在干扰物上的停留时间,作为快速排斥的衡量标准。我们发现,在困难搜索条件下,负模板有更多的注意力引导。此外,我们发现,在困难搜索条件下,负模板的快速排斥有更大的优势。虽然我们通常关注模板作为引导注意力的一种方式,但这些结果强调了注意模板的另一个关键作用:快速排斥干扰物。
