How can we explain the regularities in subjective reports of human observers about their subjective visual experience of a stimulus? The present study tests whether a recent model of confidence in perceptual decisions, the weighted evidence and visibility model, can be generalized from confidence to subjective visibility. In a postmasked orientation identification task, observers reported the subjective visibility of the stimulus after each single identification response. Cognitive modelling revealed that the weighted evidence and visibility model provided a superior fit to the data compared with the standard signal detection model, the signal detection model with unsystematic noise superimposed on ratings, the postdecisional accumulation model, the two-channel model, the response-congruent evidence model, the two-dimensional Bayesian model, and the constant noise and decay model. A comparison between subjective visibility and decisional confidence revealed that visibility relied more on the strength of sensory evidence about features of the stimulus irrelevant to the identification judgment and less on evidence for the identification judgment. It is argued that at least two types of evidence are required to account for subjective visibility, one related to the identification judgment, and one related to the strength of stimulation.

我们如何解释人类观察者关于刺激的主观视觉体验的主观报告中的规律？本研究测试了最近的感知决策置信度模型、加权证据和可见性模型是否可以从置信度推广到主观可见性。在后掩蔽方向识别任务中，观察者报告了每个单一识别响应后刺激的主观可见性。认知建模表明，与标准信号检测模型、非系统噪声叠加在评级上的信号检测模型、决策后累积模型、双通道模型、响应-全等证据模型，二维贝叶斯模型，以及恒定噪声和衰减模型。主观能见度与决策置信度的比较表明，能见度更多地依赖于与识别判断无关的刺激特征的感官证据的强度，而更少地依赖于识别判断的证据。有人认为，至少需要两种类型的证据来解释主观可见性，一种与身份判断有关，一种与刺激强度有关。
