Attention has long been characterized within prominent models as reflecting a competition between goal-driven and stimulus-driven processes. It remains unclear, however, how involuntary attentional capture by affective stimuli, such as threat-laden content, fits into such models. Although such effects were traditionally thought to reflect stimulus-driven processes, recent research has increasingly implicated a critical role of goal-driven processes. Here we test an alternative goal-driven account of involuntary attentional capture by threat using an experimental manipulation of goal-driven attention. To this end we combined the classic contingent capture and emotion-induced blink paradigms in an RSVP task with both positive or threatening target search goals. Across 6 experiments, positive and threat distractors were presented in peripheral, parafoveal, and central locations. Across all distractor locations we found that involuntary attentional capture by irrelevant threat distractors could be induced via the adoption of a search goal for a threatening category; adopting a goal for a positive category conversely led to capture only by positive stimuli. Our findings provide direct experimental evidence for a causal role of voluntary goals in involuntary capture by irrelevant threat stimuli, and hence demonstrate the plausibility of a top-down account of this phenomenon. We discuss the implications of these findings in relation to current cognitive models of attention and clinical disorders. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
注意长期以来一直被突出的模型刻画为反映了目标驱动和刺激驱动过程之间的竞争。然而,目前尚不清楚,诸如威胁性内容等情感刺激的非自愿注意力捕捉是如何适应这些模型的。尽管传统上认为这些影响反映了刺激驱动的过程,但最近的研究越来越表明目标驱动过程的关键作用。在这里,我们使用目标驱动注意的实验操作来测试一种替代性的目标驱动理论,以解释威胁引起的非自愿注意力捕捉。为此,我们在 RSVP 任务中结合了经典的条件捕捉和情绪诱导眨眼范式,同时具有积极或威胁性的目标搜索目标。在 6 项实验中,我们在周边、旁中心和中央位置呈现了积极和威胁性的分心物。在所有分心物位置,我们发现,通过采用对威胁性类别的搜索目标,无关的威胁分心物可以引起非自愿的注意力捕捉;相反,采用积极类别的目标则只能引起对积极刺激的捕捉。我们的发现为无关威胁刺激的非自愿捕捉中自愿目标的因果作用提供了直接的实验证据,从而证明了自上而下的解释这一现象的合理性。我们讨论了这些发现对当前注意认知模型和临床障碍的意义。
