Here, we first demonstrate the existence of a window of subliminal perception in humans using different experimental paradigms and analysis methods. We then show that the standard signal detection theory (SDT) model is unable to accounts for this window and extend it until it is. We finally compare a range of models on empirical data. The models performing best are notable for their absence of hierarchical levels, indicating that the window could be a base property of any phenomenally conscious system. The models further explain previously incompatible findings in the literature, and they allow for estimations of peaks in subthreshold perception across the spectrum of stimulus saliency, which may be used in further studies of subliminal perception.</p>OPENPsyArXiv|Social and Behavioral Sciences|Perception|VisionConsciousnessVisionPerceptual awareness scalePsyArXiv|Social and Behavioral Sciences|Cognitive Psychology|Consciousnessbepress|Social and Behavioral Sciences|Psychology|Cognition and Perceptionbepress|Social and Behavioral Sciences|Psychology|Quantitative PsychologySubliminal StimulationSocial and Behavioral SciencesHumansQuantitative MethodsUnconscious perceptionUnconscious, PsychologyPsyArXiv|Social and Behavioral Sciences|PerceptionComputational ModelingCognitive PsychologyPsyArXiv|Social and Behavioral Sciences|Quantitative Methods|Computational ModelingAwarenessbepress|Social and Behavioral Sciences|Psychology|Cognitive PsychologyPsyArXiv|Social and Behavioral SciencesSignal detection theorybepress|Social and Behavioral SciencesPsyArXiv|Social and Behavioral Sciences|Cognitive PsychologyPerceptionPsyArXiv|Social and Behavioral Sciences|Quantitative MethodsSubliminal perceptionpublication03 medical and health sciences0302 clinical medicine0501 psychology and cognitive sciences05 social sciencesdoi_dedup___:74f308bf59a50c6850eced74c3423c3935301023
