Life & Consciousness
Global Workspace Theory
Models consciousness as information being broadcast widely across the brain via a shared “workspace,” making it available to many specialized unconscious processes at once.
Proponents
Bernard Baars, Stanislas Dehaene, Jean-Pierre Changeux
Evidence For
Neuroimaging shows a distinctive, widespread pattern of brain activity ("ignition") correlating with conscious perception versus unconscious processing of the same stimulus.
Evidence Against
Critics argue broadcast/access to information may explain reportability and cognition without fully explaining subjective experience itself (see the Hard Problem).
