Here, we explore the sensitivity of different awareness scales in revealing conscious reports on visual emotion perception. Participants were exposed to a backward masking task involving fearful faces and asked to rate their conscious awareness in perceiving emotion in facial expression using three different subjective measures: confidence ratings (CRs), with the conventional taxonomy of certainty, the perceptual awareness scale (PAS), through which participants categorize "raw" visual experience, and post-decision wagering (PDW), which involves economic categorization. Our results show that the CR measure was the most exhaustive and the most graded. In contrast, the PAS and PDW measures suggested instead that consciousness of emotional stimuli is dichotomous. Possible explanations of the inconsistency were discussed. Finally, our results also indicate that PDW biases awareness ratings by enhancing first-order accuracy of emotion perception. This effect was possibly a result of higher motivation induced by monetary incentives.
在这里，我们探讨了不同意识量表在揭示视觉情绪感知的有意识报告方面的敏感性。参与者接受了涉及恐惧面孔的后向掩蔽任务，并使用三种不同的主观测量方法（置信度评分（CRs）、传统的确定性分类法、感知意识量表（PAS），参与者通过该量表对“原始”视觉体验进行分类，以及决策后押注（PDW），涉及经济分类）来评估他们对感知面部表情中的情绪的有意识程度。我们的结果表明，CR 测量是最详尽和最分级的。相比之下，PAS 和 PDW 测量则表明对情绪刺激的意识是二分的。讨论了不一致的可能解释。最后，我们的结果还表明，PDW 通过提高情绪感知的一阶准确性来影响意识评分。这种效果可能是由于金钱奖励引起的更高动机所致。
