Predictive processing theories are unlocking deep mysteries of the mind. Solving the hard problem of consciousness will require a multifaceted approach and an evolutionary lens.
Here’s how to understand integrated information theory (IIT). The consciousness theory is popular among (if barely understood by) the media but has polarized scientists.
GWTs posit that information becomes conscious when it gains the brain’s attentional spotlight and is broadcast to a global workspace. Experts like GWT; the media have other ideas.
Higher-order theories of consciousness posit that mental states become conscious when re-represented by higher-order mental states in the prefrontal cortex. Here’s what that means.
The scientific study of consciousness has come of age. At this still-early stage, there is a plethora of fascinating theories. Here’s a look at the main contenders.
In principle, building sentient AI should be possible, given the physical basis of consciousness. Whether it’s a good idea is another question entirely.
