 Since generic consciousness is a matter of a state’s being conscious or not, we can examine work on specific types of mental state that shift between being conscious or not and isolate neural substrates. Work on unconscious vision provides an informative example. In the past decades, scientists have argued for unconscious seeing and investigated its brain basis especially in neuropsychology, the study of subjects with brain damage. Interestingly, if there is unconscious seeing, then the intentional action inference must be restricted in scope since some intentional behaviors might be guided by unconscious perception  (section 2.5).  That is, the existence of unconscious perception blocks a direct inference from perceptually guided intentional behavior to perceptual consciousness. The case study of unconscious vision promises to illuminate more specific studies of generic consciousness along with having repercussions for how we attribute conscious states.
