Event-related potentials (ERPs) were measured in response to the objective offset of a visual disk under two physically similar conditions: (1) visible conditions in which the target disk was well perceived and (2) invisible conditions in which participants reported to have not seen the target because of motion-induced blindness (Bonneh, Cooperman, & Sagi in Nature 411:798-801, 2001). Electrophysiological responses to the physical offset of the target disk were almost completely absent in the invisible conditions (Experiment 2). In the same conditions, the physical offset was almost completely invisible (Experiment 1). Results suggest an augmenting function of prior awareness of a stimulus for the offset-triggered ERP of that stimulus.
在两种物理条件相似的情况下，测量了与事件相关电位（ERP）对视觉圆盘客观消失的反应：（1）可见条件，即目标圆盘能被清晰感知；（2）不可见条件，即参与者报告由于运动诱导失明而未看到目标（Bonneh、Cooperman和Sagi，《自然》411:798 - 801，2001）。在不可见条件下，对目标圆盘物理消失的电生理反应几乎完全不存在（实验2）。在相同条件下，物理消失几乎完全不可见（实验1）。结果表明，对刺激的预先感知对该刺激的消失触发ERP具有增强作用。
