 A natural interpretation of these experiments is as showing that the erotic pictures capture the participants’ attention, despite the fact that those participants have no conscious experience of them. This suggests—although it does not conclusively demonstrate—that one may be attending to a thing without being conscious of it. The same conclusion is suggested by a quite different set of experiments involving a patient with blindsight.  These experiments show that, even though the blindsighted patient has no experience of cues presented in his scotoma, those cues can elicit the facilitation of processing and reduction of reaction times that are usually taken to be the signatures of attention (Kentridge &amp; Heywood, 2001, Kentridge et al., 2004).
