Although visual consciousness can be manipulated easily (e.g., by visual masking), it is unresolved whether it can be assessed accurately with behavioral measures such as discrimination ability and self-report. Older theories of visual consciousness postulated a sensory threshold and distinguished between subjective and objective thresholds. In contrast, newer theories distinguish among three aspects: phenomenal, access, and reflexive consciousness. This review shows that discrimination ability and self-report differ in their sensitivity to these aspects. Therefore, both need to be assessed in the study of visual consciousness.
尽管视觉意识很容易被操控(例如,通过视觉掩蔽),但它能否通过诸如辨别能力和自我报告等行为测量方法被准确评估仍未得到解决。早期的视觉意识理论假定了一个感觉阈限,并区分了主观阈限和客观阈限。相比之下,更新的理论区分了三个方面:现象意识、通达意识和反省意识。这篇综述表明,辨别能力和自我报告在对这些方面的敏感性上存在差异。因此,在视觉意识研究中,两者都需要被评估。
