The attention schema theory (AST) of consciousness (or subjective awareness) is a neuroscientific and evolutionary theory of consciousness which was developed by neuroscientist Michael Graziano at Princeton University.[1][2] It proposes that brains construct subjective awareness as a schematic model of the process of attention.[1][2] The theory is a materialist theory of consciousness. It shares similarities with the illusionist ideas of philosophers like Daniel Dennett, Patricia Churchland, and Keith Frankish.[3][4]
Graziano proposed that an attention schema is like the body schema. Just like the brain constructs a simplified model of the body to help monitor and control movements of the body, so the brain constructs a simplified model of attention to help monitor and control attention. The information in that model, portraying an imperfect and simplified version of attention, leads the brain to conclude that it has a non-physical essence of awareness. The construct of subjective awareness is the brain's efficient but imperfect model of its own attention. This approach is intended to explain how awareness and attention are similar in many respects, yet are sometimes dissociated, how the brain can be aware of both internal and external events, and also provides testable predictions.[2]
