Continuous Flash Suppression (CFS) reduces conscious awareness of stimuli. Whether stimuli suppressed by CFS are processed at categorical or semantic levels is still debated. Here, we approached this question using a large set of indoor and outdoor scene photographs in a priming paradigm. Perceptually suppressed primes were followed by visible targets. Participants rapidly reported whether the targets showed an indoor or an outdoor scene. Responses were faster (and fast responses more accurate) when primes and targets came from a congruent superordinate category (e.g., both were outdoor scenes). During CFS, priming effects were relatively small (up to 10 ms) and modulated by prime visibility and stimulus onset asynchrony (SOA) of prime and target. Without CFS, the stimuli elicited consistent and more robust priming effects (about 24 ms). Our results imply that scene category is processed during CFS, although some residual prime visibility is likely necessary for significant priming effects to occur.
连续闪光抑制 (CFS) 降低了对刺激的意识感知。CFS 抑制的刺激是否在类别或语义水平上被处理仍存在争议。在这里，我们使用启动范式中的一大组室内和室外场景照片来研究这个问题。在可感知的被抑制的启动刺激后会出现可见的目标。参与者需要快速报告目标显示的是室内还是室外场景。当启动刺激和目标来自一致的上位类别（例如，两者都是室外场景）时，反应更快（快速反应更准确）。在 CFS 期间，启动效应相对较小（最多 10ms），并且受到启动刺激可见度和启动刺激与目标刺激的时间间隔（SOA）的调制。没有 CFS 时，刺激会产生一致且更强烈的启动效应（约 24ms）。我们的结果表明，在 CFS 期间处理场景类别，尽管可能需要一些残留的启动刺激可见度才能产生显著的启动效应。
