GWT: A Leading Consciousness Theory Depends on Information TheoryNot mechanism. If Global Workspace Theory (GWT) is a good approach to consciousness, there is no “consciousness spot” in the brain.
Recently, we have looked at the Integrated Information Theory (IIT) of human consciousness, as set out by well-known Allen Institute neuroscientist Christof Koch. Another leading contender (and rival) is Global Workspace Theory (GWT) — it pictures the brain as an orchestra with many conductors. IIT is panpsychist in orientation (the universe participates in consciousness; human consciousness is the most highly developed instance) whereas GWT uses information theory to capture an image of consciousness via observations of the brain at work. A recent essay in Psyche by two GWT proponents, Morten L. Kringelbach and Gustav Deco, introduces us to GWT: … given the distributed nature of the brain hierarchy, there is unlikely to be just a single ‘conductor’. Instead, in 1988 Read More ›
