One of the ongoing debates about visual consciousness is whether it can be considered as an all-or-none or a graded phenomenon. This may depend on the experimental paradigm and the task used to investigate this question. The present event-related potential study (N = 32) focuses on the attentional blink paradigm for which so far only little and mixed evidence is available. Detection of T2 face targets during the attentional blink was assessed via an objective accuracy measure (reporting the faces' gender), subjective visibility on a perceptual awareness scale (PAS) as well as event-related potentials time-locked to T2 onset (components P1, N1, N2, and P3). The behavioral results indicate a graded rather than an all-or-none pattern of visual awareness. Corresponding graded differences in the N1, N2, and P3 components were observed for the comparison of visibility levels. These findings suggest that conscious perception during the attentional blink can occur in a graded fashion.

注意眨眼期间的分级视觉意识

关于视觉意识的正在进行的辩论之一是它是否可以被视为是全有或全无或分级的现象。这可能取决于实验范式和用于研究此问题的任务。目前与事件有关的潜在研究（N = 32）集中于注意眨眼范式，到目前为止，只有很少的和混合的证据可用。通过客观准确度测量（报告面孔的性别），感知感知量表（PAS）上的主观可见性以及时间相关的电位锁定到T2发作，来评估注意眨眼期间T2面部目标的检测。 ，N1，N2和P3）。行为结果表明视觉意识是分级模式，而不是全无模式。N1，N2，观察到P3和P3成分以比较可见度。这些发现表明注意眨眼期间的意识感知可以以分级的方式发生。
