Reporting the second of two targets is impaired when these appear in close succession, a phenomenon known as the attentional blink (AB). Despite decades of research, what factors limit our ability to process multiple sequentially presented events remains unclear. Specifically, two central issues remain open: does failure to report the second target (T2) reflect a structural limitation in working memory (WM) encoding or a disruption to attentional processes? And is perceptual processing of the stimulus that we fail to report impaired, or only processes that occur after this stimulus is identified? We address these questions by reviewing event-related potential (ERP) studies of the AB, after providing a brief overview of the theoretical landscape relevant to these debates and clarifying key concepts essential for interpreting ERP studies. We show that failure to report the second target is most often associated with disrupted attentional engagement (associated with a smaller and delayed N2pc component). This disruption occurs after early processing of T2 (associated with an intact P1 component), weakens its semantic processing (typically associated with a smaller N400 component), and prevents its encoding into WM (associated with absent P3b). However, failure to encode T2 in WM can occur despite intact attentional engagement and semantic processing. We conclude that the AB phenomenon, which reflects our limited ability to process sequential events, emerges from the disruption of both attentional engagement and WM encoding.

注意眨眼期间哪些过程被打乱了?事件相关潜力研究的综合评价

当两个目标连续出现时,报告两个目标中的第二个会受到损害,这种现象称为注意眨眼 (AB)。尽管进行了数十年的研究,但哪些因素限制了我们处理多个顺序呈现的事件的能力仍不清楚。具体来说,两个核心问题仍然悬而未决:未能报告第二个目标 (T2) 是否反映了工作记忆 (WM) 编码的结构限制或注意力过程的中断?是我们未能报告的刺激的知觉处理受损,还是仅在识别该刺激后发生的过程?我们通过回顾 AB 的事件相关电位 (ERP) 研究来解决这些问题,在简要概述与这些辩论相关的理论前景并阐明解释 ERP 研究所必需的关键概念之后。我们表明,未能报告第二个目标通常与注意力参与中断(与较小和延迟的 N2pc 组件相关)有关。这种中断发生在 T2 的早期处理(与完整的 P1 组件相关)之后,削弱了其语义处理(通常与较小的 N400 组件相关),并阻止其编码为 WM(与缺失的 P3b 相关)。然而,尽管注意力参与和语义处理完好,但仍可能发生在 WM 中编码 T2 的失败。我们得出的结论是,反映我们处理连续事件的能力有限的 AB 现象源于注意力参与和 WM 编码的破坏。这种中断发生在 T2 的早期处理(与完整的 P1 组件相关)之后,削弱了其语义处理(通常与较小的 N400 组件相关),并阻止其编码为 WM(与缺失的 P3b 相关)。然而,尽管注意力参与和语义处理完好,但仍可能发生在 WM 中编码 T2 的失败。我们得出的结论是,反映我们处理连续事件的能力有限的 AB 现象源于注意力参与和 WM 编码的破坏。这种中断发生在 T2 的早期处理(与完整的 P1 组件相关)之后,削弱了其语义处理(通常与较小的 N400 组件相关),并阻止其编码为 WM(与缺失的 P3b 相关)。然而,尽管注意力参与和语义处理完好,但仍可能发生在 WM 中编码 T2 的失败。我们得出的结论是,反映我们处理连续事件的能力有限的 AB 现象源于注意力参与和 WM 编码的破坏。尽管注意力参与和语义处理完好,但仍可能发生在 WM 中编码 T2 的失败。我们得出的结论是,反映我们处理连续事件的能力有限的 AB 现象源于注意力参与和 WM 编码的破坏。尽管注意力参与和语义处理完好,但仍可能发生在 WM 中编码 T2 的失败。我们得出的结论是,反映我们处理连续事件的能力有限的 AB 现象源于注意力参与和 WM 编码的破坏。
