Inattentional blindness (IB) occurs when a salient object presented in plain sight goes unnoticed when its appearance is unexpected. Across two experiments, participants completed a classic dynamic IB task while eye movements and steady-state visual evoked potential (SSVEP) responses were continually recorded. This allowed us to measure the modulation of gaze and brain-based indices of attention during IB. While an SSVEP response to all stimuli including the unexpected object was attained, only gaze measures were able to discriminate noticers from nonnoticers. Experiment 1 used a prototypical sustained IB task and found that gaze toward the unexpected object was largely unrelated to noticing that object. Experiment 2 manipulated the contrast of the target and distractor stimuli, and instead observed a tight concordance between gazing at the unexpected object and reporting its presence. This task-based variability in gaze deployment is consistent with the broader literature and cumulatively delineates the challenges faced in translating lab-based IB research from the bench to the bedside.

非注意盲视（IB）是指当一个显著的物体出现在眼前时，如果其出现出乎意料，那么它就会被忽略。在两项实验中，参与者在完成经典的动态 IB 任务的同时，持续记录眼动和稳态视觉诱发电位（SSVEP）反应。这使我们能够测量 IB 期间注视和基于大脑的注意力指标的调制。虽然对包括意外物体在内的所有刺激都产生了 SSVEP 反应，但只有注视测量才能区分注意者和非注意者。实验 1 使用了典型的持续 IB 任务，发现注视意外物体与注意到该物体基本无关。实验 2 操纵了目标和分心刺激的对比度，反而观察到注视意外物体和报告其存在之间存在紧密的一致性。这种基于任务的注视部署的可变性与更广泛的文献一致，并累积描绘了将基于实验室的 IB 研究从实验室转化到临床所面临的挑战。（PsycInfo 数据库记录（c）2023 APA，保留所有权利）。
