Consciousness and intelligence

Chimp using a stick

The other day, when discussing Mark Solms' book, I noted that he is working to create an artificial consciousness, but that he emphasizes that he isn't aiming for intelligence, just the conscious part, as though consciousness and intelligence are unrelated. This seems to fit with his affect centered theory of consciousness, and it matches a … Continue reading Consciousness and intelligence

Structural realism, a way to be a scientific realist?

In the scientific realism vs instrumentalism debate, realism is the position that the elements of a scientific theory represent reality. So when general relativity talks about space warping, space really is warping. Instrumentalism, or anti-realism, is the stance that scientific theories are just prediction mechanisms, with no guarantee that they represent reality. Under instrumentalism, general … Continue reading Structural realism, a way to be a scientific realist?

A perceptual hierarchy of consciousness

I've discussed many times how difficult consciousness can be to define. One of the earliest modern definitions, from John Locke, was, "the perception of what passes in a man's own mind." This definition makes consciousness inherently about introspection. But other definitions over the centuries have focused on knowledge in general as well as intentionality, the … Continue reading A perceptual hierarchy of consciousness

Stimulating the prefrontal cortex

(Warning: neuroscience weeds) This is an interesting study getting attention on social media: Does the Prefrontal Cortex Play an Essential Role in Consciousness? Insights from Intracranial Electrical Stimulation of the Human Brain. Ned Block is one of the authors. (Warning: paywalled, but you might have luck here.) The study looks at data from epileptic patients … Continue reading Stimulating the prefrontal cortex

The global playground

(Warning: neuroscience weeds) Stanislas Dehaene recently called attention to a paper in Nature studying the brain dynamics of something becoming conscious. The study supports the global neuronal workspace theory that consciousness involves "bifurcation" dynamics, an "ignition", a phase transition between preconscious and conscious processing. Prior to the transition, the processing is feedforward and fleeting. After … Continue reading The global playground
