Consciousness as Social Perception (BSP 108)

Michal Graziano and Kevin

Michal Graziano and Kevin

In his latest book Consciousness and the Social Brain  Princeton neuroscientist Michael Graziano proposes a unique and compelling theory of consciousness. He proposes that the same circuits that the human brain uses to attribute awareness to others are used to model self-awareness. He emphasizes that his attention schema theory is only tentative, but it is testable and it does fit our current knowledge of brain function.

In a recent interview for the Brain Science Podcast (BSP 108), Graziano used the following clinical example to clarify his approach. A colleague had a patient who was convinced that he had a squirrel in his head. When confronted with the illogic of his claim the patient replied “Not everything can be explained by science.” In this example it is clear that the squirrel doesn’t really exist, so the question to be answered is HOW did his brain reach the conclusion that it does.

How to get this episode:

While imagining one has a squirrel in one’s head is thankfully rare, we also know that our subjective experiences of the world are not necessarily accurate. Our perception of the world is shaped by how our brain processes the sensory inputs it receives. For example, we perceive white light as an absence of color even though in reality it consists of all wavelengths.

Perception is something our brains do constantly and which we can not consciously control. In considering awareness (and by extension consciousness) perception-like Graziano is emphasizing several important features. The most important is probably the fact that it is only “quick and dirty model” of what is really going on, which means that our intuitions about consciousness are not necessarily reliable. In fact, humans have a strong tendency to over-attribute awareness to the world around us. This is part of the social circuitry that has made us the most successful species in the earth’s history, but it can also lead to amusing results (as anyone who has interacted with Siri on an iPhone has no doubt observed).

Another implication of considering awareness as a form of social perception is that it reverses the usual approach taken to understanding consciousness. Instead of asking how a physical brain can produce something subjective and non-physical called consciousness, we ask what kind of information processing leads to the conclusion that I (or anyone else) is conscious. As Graziano points out, this is a “mechanistic” model. Not only can it be tested but it has interesting implications. Dr. Graziano concluded that one of the key implications is "that awareness and consciousness are tools for information processing, and they are mechanistically understandable, and presumably can be engineered.”

I find the attention schema theory to be very compelling. Besides being testable, it has a simple elegance that I appreciate. It also explains why most humans experience a world filled with spirits, and are utterly convinced that their own consciousness is something special and non-physical.

Related Episodes:

Since understanding consciousness is one of the deepest questions facing neuroscience, it has been explored on many previous episodes of the Brain Science Podcast. Rather than list all those episodes I want to mention just a few that I think are particularly relevant to this month’s episode.

Sleep Science with Penny Lewis (BSP 107)

Penny Lewis

Penny Lewis

In The Secret World of Sleep: The Surprising Science of the Mind at Rest Dr. Penelope A. Lewis provides a highly readable account of the fascinating world of sleep research. Fascinating research is being carried out with animals as varied as fruit flies and rats, as well as with humans. I was surprised to learn that most people actually find it fairly easy to fall asleep in an fMRI scanner.

I have just posted an interview with Dr. Lewis (BSP 107) that includes a discussion of the role of sleep in memory as well as interesting findings about how synapses in the brain actually change during sleep. We still don't know exactly what sleep (and dreaming) are essential, but research in this field is growing. Dr. Lewis is excited about emerging research that suggests improving slow wave sleep may significantly improve learning and memory.

"The Autistic Brain" by Temple Grandin (BSP 98)

 The Autistic Brain: Thinking Across the Spectrum  by Temple Grandin (with Richard Panek), is a tremendous gift, not just to patients and their families, but also to teachers, mentors, friends, and everyone who is interested in understanding how our brains make us who we are.

I think that this is a book everyone should read because as we come to appreciate the fact that the strengths and challenges of autism occur across a broad spectrum, we may also realize that some of these issues actually affect people who aren't considered autistic.  It is not the label that matters.  What does matter is recognizing that each of us has his or her own strengths and weaknesses, but thanks to brain plasticity, we all have the potential to nurture our strengths and, when necessary, accommodate our weaknesses.

"The Self Illusion" with Bruce Hood (BSP 88)

BruceHood.jpg

Bruce Hood, PhD

 

The Self Illusion: How the Social Brain Creates Identity, by Bruce Hood, is a fascinating look at how our brains create both our experience of the world and our sense of being a single, coherent self.  As the word "illusion" in the title indicates, neither is exactly what it seems.  When I interviewed Dr. Hood (BSP 88), he explained that The Self Illusion is a broad introduction to this somewhat surprising idea. TheSelf Illusion was written with a general audience in mind.  For those already familiar with the topic, he also puts a new emphasis on the role of development.  All readers should come away with a new appreciation for the critical role social interactions play through out human life.

Memory: Challenging Current Theories with Randy Gallistel, PhD (BSP 66)

Episode 66 of the Brain Science Podcast is an interview with Randy Gallistel, PhD, Co-Director of the Rutgers Center for Cognitive Science and co-author (with Adam Philip King) of Memory and the Computational Brain: Why Cognitive Science Will Transform Neuroscience.

We discuss why read/write memory is an essential element of computation, with an emphasis on the animal experiments that support the claim that brains must possess read/write memory.  This is significant because current models, such as neural nets, DO NOT incorporate read/write memory in their assumptions about how brains work.  It is not necessary to have any background in information theory or computation to appreciate the experiments that are discussed in this episode.
