Leading Consciousness Theory Slammed as “Pseudoscience.” Huh?

Integrated Information Theory’s panpsychist leanings are the 124 neuroscientist critics’ real target

Since last week, 124 neuroscientists, including some really big names, have signed an online letter,” to be published in a journal, denouncing a leading theory of consciousness, Integrated Information Theory (IIT), as “pseudoscience.” If you don’t follow these controversies, IIT may not immediately ring a bell. But the theory featured in popular science news earlier this summer when dualist philosopher David Chalmers won a 25-year bet with IIT neuroscientist Christof Koch. He had bet that a “consciousness spot” would not be found in the brain and it was not. But they were both good sports about it and, as agreed, Koch bought Chalmers a case of fine wine. But the signatories to the letter are in no mood for parties. Read More ›

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 Read More ›
