The consciousness of crows

Last week, Science Magazine published an interesting study on bird consciousness: A neural correlate of sensory consciousness in a corvid bird.  The study conducted an experiment where crows were trained to respond to a sensory stimulus.  The stimulus itself could be at the threshold of perceptibility, above that threshold, or missing.  After the stimulus (or … Continue reading The consciousness of crows

The facilitation hypothesis

Jonathan Birch has an interesting paper in Noûs: The search for invertebrate consciousness.  Birch notes that there is no consensus on whether any invertebrates are conscious, and no agreement on a methodology for establishing whether they are. He starts off assessing the difficulties of applying many human centric theories, such as global workspace, which don't … Continue reading The facilitation hypothesis

Dimensions of animal consciousness

The journal, Trends in Cognitive Science, has an interesting paper up: Dimensions of Animal Consciousness.  After noting the current consensus that some form of consciousness is present in at least mammals, birds, and cephalopods, it looks at how to evaluate it in various species.  The authors take the position that consciousness can be present in … Continue reading Dimensions of animal consciousness

Final thoughts on The Evolution of the Sensitive Soul

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

The sensitive soul and the rational soul

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

For animal consciousness, is there a fact of the matter?

Peter Carruthers has been blogging this week on the thesis of his new book, Human and Animal Minds: The Consciousness Question Laid to Rest.  I mentioned Carruthers' book in my post on global workspace theory (GWT), but didn't get into the details.  While I had been considering taking a fresh look at GWT, his book … Continue reading For animal consciousness, is there a fact of the matter?
