GWT: A Leading Consciousness Theory Depends on Information Theory

Not 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…

Quick Facts on IIT (the Leading Theory of Consciousness)

IIT may be part of a trend in science in which emergence and panpsychist theories are slowly replacing materialist and physicalist ones

Consciousness, as a concept, is so easy to experience and so hard to define. Or explain. The most popular current theory of consciousness is Integrated Information Theory (IIT), pioneered by neuroscientist Giulio Tononi and championed by Allen Institute neuroscientist Christof Koch. For the purpose of discussing IIT, science writer Mike Hogan works with this definition: Consciousness for purposes of this theory is defined as ‘self-awareness’ or the Central-Identity; the inner-voice that allows your brain to talk to itself, an awareness that ‘you’ exist, the rationalization of your own relevance to that existence, and an awareness of the cause and effect of your actions in regard to yourself and your environment. Mike Hogan, “The Best Available Story of Human Consciousness” at…

Can Machines Be Given Consciousness?

A prominent researcher in consciousness studies offers reasons for doubt

Two theories of human consciousness are about to be tested in a historic contest. Integrated Information Theory (IIT) of consciousness and rival Global Workspace Theory (GWT) have sharply different implications for consciousness in machines.

Quest for Consciousness: A Historic Contest Is Announced

The two theories to be tested pit "information processing" against "causal power" as a model of consciousness. One side must admit it is wrong

Consciousness is a slippery concept but the two prominent theories make different predictions as to which part of the brain will become active when a person becomes aware of an image; thus they can be tested by neuroscientists.
