  2. In the Theater of Consciousness - a useful theoretical metaphor --- only the bright spot on stage is conscious (because consciousness is very limited in capacity) --- sensory inputs compete for access to the conscious bright spot; so do output plans; --- the "theater stage" corresponds to Working Memory; --- all other parts are unconscious, including longterm memory, the automatic processes of language, and events going on backstage. (The capacity of unconsciousness is enormous.) -- the theater metaphor has been turned into several testable models. @, B.J. Baars, 2008 From Carl Carpenter, A New Model of Consciousnes, Sci& Con Rev.2006.

  3. Selective attention controls the spotlight that selects what will be in the bright spot on stage Backstage is unconscious The audience is unconscious @, B.J. Baars, 2008

  4. Here is a brain version of global workspace theory: Prediction: Conscious input activates more widely than similar unconscious input. • Notice that there are two sensory inputs (the red and green arrows), and that the winning input evokes widespread "forward" activity in the brain.
