最近，Windey，Gevers和Cleeremans（2013）提出了一个加工水平（Lop）假说，声称从无意识到有意识的感知的过渡受到任务要求所施加的加工水平的影响。在这里，我们进行了两个实验来测试LoP假设。在这两种情况下，参与者被要求根据字母的物理特征（低级任务）或语义规则（高级任务）将简要呈现的字母对分类为相同或不同。通过四点感知意识量表（PAS）测量刺激意识。结果表明，低或中等刺激可见性的报告更频繁地在低水平的任务比在高水平的任务，这表明从无意识到有意识的知觉的过渡是在前者比后者更渐进。因此，尽管其他解释仍然是可能的，本研究的结果完全支持LoP假设。(C)2015 Elsevier Inc.

Recently, Windey, Gevers, and Cleeremans (2013) proposed a level of processing (Lop) hypothesis claiming that the transition from unconscious to conscious perception is influenced by the level of processing imposed by task requirements. Here, we carried out two experiments to test the LoP hypothesis. In both, participants were asked to classify briefly presented pairs of letters as same or different, based either on the letters' physical features (a low-level task), or on a semantic rule (a high-level task). Stimulus awareness was measured by means of the four-point Perceptual Awareness Scale (PAS). The results showed that low or moderate stimulus visibility was reported more frequently in the low-level task than in the high-level task, suggesting that the transition from unconscious to conscious perception is more gradual in the former than in the latter. Therefore, although alternative interpretations remain possible, the results of the present study fully support the LoP hypothesis. (C) 2015 Elsevier Inc. All rights reserved.
