Ponderings of science, philosophy, history, society, and many other topics
Recently, there was a debate on Twitter between neuroscientists Hakwan Lau and Victor Lamme, both of whose work I've highlighted here before. Lau is a proponent of higher order theories of consciousness, and Lamme of local recurrent processing theory. The debate began when Lau made a statement about panpsychism, the idea that everything is conscious … Continue reading The issues with biopsychism
(Warning: neuroscience weeds) Recently I noted that one of the current debates in cognitive science is between those who see phenomenal and access consciousness as separate things, and those who see them as different aspects of the same thing. Closely related, perhaps actually identical, is the debate between local and global theories of consciousness. Local … Continue reading Postdictive perception and the consciousness finish line
One of the current debates in consciousness research is whether phenomenal consciousness is something separate and apart from access consciousness. Access consciousness (A-consciousness) is generally defined as perceptions being accessible for reasoning, action decisions, and communication. Phenomenal consciousness (P-consciousness) is seen as raw experience, the "something it is like" aspect of consciousness. Most researchers accept … Continue reading Subjective report doesn’t support the idea that phenomenal consciousness is separate from access consciousness
This is the final post in a series I've been doing on Simona Ginsburg and Eva Jablonka’s book: The Evolution of the Sensitive Soul, a book focused on the evolution of minimal consciousness. This is a large book, and it covers a wide range of ideas. A series of relatively small blog posts can't do them … Continue reading Final thoughts on The Evolution of the Sensitive Soul
This is part of a series on Simona Ginsburg and Eva Jablonka’s book: The Evolution of the Sensitive Soul, a book focused on the evolution of minimal consciousness. This particular post is on the capabilities Ginsburg and Jablonka (G&J) see as necessary to attribute consciousness to a particular species. The capability they focus on is … Continue reading Unlimited associative learning
I'm still working my way through Simona Ginsburg and Eva Jablonka's tome: The Evolution of the Sensitive Soul. This is the second post of a series on their book. I'm actually on the last chapter, but that last chapter is close to a hundred pages long, and the book's prose is dense. Light reading it … Continue reading The seven attributes of minimal consciousness
I think examining the evolution of consciousness in animals helps shed light on it in humans. Admittedly, there are difficulties. Animals can't self report using language, which limits just how much of their experience can be garnered from experiments. Still, taking data from human studies and combining it with animal studies can provide a lot … Continue reading The sensitive soul and the rational soul
(Warning: neuroscience weeds) An interesting paper by Tim Bayne, Anil Seth, and Marcello Massimi, which came up in my Twitter stream today, asks whether there can be islands of awareness. Ordinary consciousness involves ongoing interaction with the environment, receiving sensory information, and producing motor output. It has a functional role, enabling an organism to deal … Continue reading Islands of awareness
This old talk by Daniel Dennett touches on a lot of topics we've discussed recently. Dennett explains why it's wrong to regard phenomenal consciousness (the "what it's likeness" or "raw experience" version) as separate from access consciousness (the cognitive access of information for decision making, memory, report, etc). Note that Dennett doesn't deny the existence … Continue reading Daniel Dennett on why phenomenal consciousness is access consciousness
(Warning: neuroscience weeds) A couple of people have asked me about this study, described in numerous popular science articles (such as this one). A monkey had electrodes installed in its brain that allowed scientists to stimulate parts of its thalamus, the region at the center of the brain which links the cortex to the brainstem … Continue reading Stimulating the central lateral thalamus produces consciousness
