We’ve investigated Damasio‘s various forms of consciousness, from proto to core to narrative, as well as Dehaene‘s 2 forms. This Scientific American article reiterates at least the 2 different kinds.

“Jonathan Schooler has established a clear distinction between conscious and meta-conscious processes. Whereas both types entail the qualities of experience, meta-conscious processes also entail what he called re-representation. […] Attention plays an important role is in re-representation; that is, the conscious knowledge of an experience, which underlies introspection. Subjects cannot report—not even to themselves—experiences that aren’t re-represented. Nothing, however, stops conscious experience from occurring without re-representation. […] Clearly, the assumption that consciousness is limited to re-represented mental contents under the focus of attention mistakenly conflates meta-consciousness with consciousness proper.”
