当视觉刺激被共有相同起始点的圆点包围时，视觉刺激可能无法达到有意识的意识，但在目标移除后仍然可见，这种现象被称为对象替换掩蔽(OSM)。在面孔/房屋分类任务中，我们通过记录人类事件相关电位的N170成分来评估替换位点。延迟偏移点损害了目标分类，通过将其影响扩展到真实的、复杂的刺激，证实了目标替换掩蔽的普遍性。此外，物体替换掩蔽消除了面孔和房屋之间的N170幅度差异，提供了第一个神经证据，证明物体替换掩蔽在物体识别过程中扰乱了结构编码阶段。
Visual stimuli can fail to reach conscious awareness when surrounded by dots sharing a common onset but remaining visible after target removal, a phenomenon known as object substitution masking (OSM). We assessed the locus of substitution by recording the N170 component of the human event-related potential during a face/house classification task. Delayed-offset dots impaired target categorization, confirming the generality of object substitution masking by extending the effect to realistic, complex stimuli. Furthermore, object substitution masking eliminated the N170 amplitude difference between faces and houses, providing the first neural evidence that object substitution masking disrupts structural encoding stages during object recognition.
