 This particular role is most directly and definitionally tied to the notion of access consciousness (Block 1995), but meta-mental consciousness as well as the phenomenal and qualitative forms all seem plausibly linked to such increases in the availability of information (Armstrong 1981, Tye 1985). Diverse cognitive and neuro-cognitive theories incorporate access as a central feature of consciousness and conscious processing. Global Workspace theories, Prinz's Attendend Intermediate Representation (AIR) (Prinz 2012) and Tononi's Integrated Information Theory (IIT) all distinguish conscious states and processes at least partly in terms of enhanced wide spread access to the state's content (see section 9.6).
