In this study we tested the hypothesis that perceptual awareness judgments are sensitive to accuracy feedback about the previous action. We used a perceptual discrimination task in which participants reported their stimulus awareness. We created two conditions: No-feedback and Feedback (discrimination accuracy feedback was provided at the end of each trial). The results showed that visual awareness judgments are related to the accuracy of current and previous responses. Participants reported lower stimulus awareness for incorrectly versus correctly discriminated stimuli in both conditions; they also reported lower stimulus awareness in trials preceded by incorrect discrimination responses, compared to trials preceded by correct discrimination responses. This difference was significantly stronger in the Feedback condition, in which we also observed post-error slowing for PAS ratings. We discuss the relation between visual awareness and the effects of performance monitoring and interpret the results in the context of current theories of consciousness.
在这项研究中，我们检验了这样一个假设，即知觉意识判断对关于先前动作的准确性反馈敏感。我们使用了一种知觉辨别任务，参与者报告他们的刺激意识。我们创建了两种条件：无反馈和反馈（在每次试验结束时提供辨别准确性反馈）。结果表明，视觉意识判断与当前和先前反应的准确性有关。在两种条件下，参与者对错误和正确辨别刺激的报告的刺激意识较低；与正确辨别反应之前的试验相比，他们对错误辨别反应之前的试验报告的刺激意识较低。在反馈条件下，这种差异更为明显，我们还观察到 PAS 评分的后错误减速。我们讨论了视觉意识与绩效监测的关系，并在意识的现有理论背景下解释了结果。
