Decades of research on visual perception has uncovered many phenomena, such as binocular rivalry, backward masking, and the attentional blink, that reflect 'failures of consciousness'. Although stimuli do not reach awareness in these paradigms, there is evidence that they nevertheless undergo semantic processing. Object substitution masking (OSM), however, appears to be the exception to this rule. In OSM, a temporally-trailing four-dot mask interferes with target perception, even though it has different contours from and does not spatially overlap with the target. Previous research suggests that OSM has an early locus, blocking the extraction of semantic information. Here, we refute this claim, showing implicit semantic perception in OSM using a target-mask priming paradigm. We conclude that semantic information suppressed via OSM can nevertheless guide behavior.
数十年的视觉感知研究揭示了许多现象，例如双眼竞争、后向掩蔽和注意瞬脱，这些现象反映了“意识的失败”。尽管在这些范式中刺激没有达到意识水平，但有证据表明它们仍然经历语义处理。然而，物体替代掩蔽 (OSM) 似乎是例外。在 OSM 中，一个尾随的四个点的掩蔽会干扰目标的感知，即使它与目标的轮廓不同且不与目标空间重叠。先前的研究表明，OSM 具有早期的位置，阻止了语义信息的提取。在这里，我们通过使用目标掩蔽启动范式来反驳这一说法，证明了 OSM 中的内隐语义感知。我们的结论是，通过 OSM 抑制的语义信息仍然可以指导行为。
