Does level of processing affect the transition from unconscious to conscious perception?

摘要: 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 imposed task requirements. Here, we carried out two experiments test LoP hypothesis. In both, participants were asked classify briefly presented pairs letters as same or different, based either on letters’ physical features (a low-level task), semantic rule high-level task). Stimulus awareness was measured means four-point Perceptual Awareness Scale (PAS). The results showed low moderate stimulus visibility reported more frequently in than task, suggesting gradual former latter. Therefore, although alternative interpretations remain possible, present study fully support
