Abstract

Recent event-related potential (ERP) studies showed that individuals with low visual working memory (VWM) capacity are more susceptible to salience-driven attentional capture than high-capacity individuals are, with the latter being able to proactively suppress salient but irrelevant distractors. However, it remains unclear whether and how contingent attentional capture by distractors that possess a task-relevant (target) feature is related to VWM capacity. Here, we adopted a central focused-attention task that contained peripheral target-matching distractors to investigate this issue (N = 51 adults). Surprisingly, we revealed that target-matching distractors elicited both a larger N2-posterior-contralateral (N2pc) and a larger post-N2pc distractor positivity (PD) component in high-capacity individuals than in low-capacity ones, meaning that high-capacity individuals are less able to ignore such distractors initially, though they could call on a stronger reactive suppression mechanism afterward. These findings illustrate that high-capacity individuals are more (rather than less or equally) susceptible to contingent attention capture compared with low-capacity ones.

易受目标匹配干扰物的注意力捕获影响可预测高视觉工作记忆能力
最近的事件相关电位(ERP)研究表明,视觉工作记忆(VWM)容量低的个体比容量高的个体更容易受到突出性驱动的注意捕获的影响,后者能够主动抑制突出但不相关的分心物。然而,具有任务相关(目标)特征的分心物的或然注意捕获是否以及如何与 VWM 容量相关,目前仍不清楚。在此,我们采用了一项包含外围目标匹配分心物的中心集中注意任务来研究这个问题(N = 51 名成人)。出乎意料的是,我们发现,与低能力者相比,高能力者在目标匹配分心物引起的N2-后部-外侧(N2pc)和N2pc后分心物阳性(PD)成分都更大,这意味着高能力者最初忽略此类分心物的能力较弱,但之后他们可以调用更强的反应性抑制机制。这些发现说明,与低能力者相比,高能力者更容易(而不是较少或同样)受到或然注意捕获的影响。
