最近的研究表明，使用掩蔽技术结合电生理记录是研究视觉意识神经相关性的一种有前途的方法。在此，我对这一努力的下列典型令人困惑的方面发表评论，这些方面阻碍了可能取得更令人印象深刻的进展。第一，客观刺激变量和主观依赖措施之间的持续混淆。第二，时间的复杂性，主观意识的出现，这部分是由于目标和面具之间的复杂互动。第三，意识的神经相关物概念的模糊性。(C)2009 Elsevier Inc. All rights reserved.
Using masking techniques combined with electrophysiological recordings is a promising way to study neural correlates of visual awareness, as shown in recent studies. Here I comment on the following puzzling aspects typical for this endeavour that have made obstacles for a potentially even more impressive progress. First, the continuing practice of confounds between objective stimulus variables and subjective dependent measures. Second, complexity of timing the emergence of subjective conscious percept which is partly due to complex interactivity between target and mask. Third, the ambiguity of the concept of neural correlates of awareness. (C) 2009 Elsevier Inc. All rights reserved.
