Robert Burton's "Skeptic's Guide to the Mind" (BSP 96)

In On Being Certain: Believing You Are Right Even When You're Not Robert Burton showed that the feeling of certainty, which is something we all experience, has its origin in brain processes that are both unconscious and inaccessible to consciousness. Now in his new book A Skeptic's Guide to the Mind: What Neuroscience Can and Cannot Tell Us About Ourselves he extends these ideas to other mental sensations such as our feeling of agency and our sense of causation. The idea that much of what our brain does is not accessible to our conscious awareness is NOT new, but Dr. Burton considers the implications for our understanding of the MIND.

When we talked recently (BSP 96) Dr. Burton explained that his new book has two main parts.  In the early chapters, he extends the principles he developed in On Being Certain to other mental sensations. We tend to take things like our feeling of certainty, agency, and causation for granted, but he points out that these are generated in parts of the brain that we can neither access or control. What makes A Skeptic's Guide to the Mind stand out is that Burton then explores the implications of this reality. He argues that while we can become ever more knowledgeable about how our brain works, the MIND, which is something that we each experience subjectively, is much more elusive.

The fact that we are trying to study the MIND with the MIND has inherent limitations and I think that Dr. Burton is right when he says our response should be HUMILITY.

Neuroscience Highlights for 2012 (BSP 92)

The Brain Science Podcast recently passed 4 million downloads and it remains entrenched at or near the top of the iTunes rankings for Science and Medicine. So now it's time for our 6th Annual Review Episode. The purpose of this year-ending podcast is to review some of the year's highlights and key ideas. As I reviewed the transcripts of this year's episodes, I was struck by the fact that although each episode stands alone, they also inform one another. One unifying theme was the importance of taking an evolutionary approach to understanding how the human brain generates complex features like mind and consciousness.

Interviews have become an outstanding feature of the Brain Science Podcast. This year I interviewed 10 scientist, including five who have appeared in past podcasts.

"Mind in Life" with Evan Thompson (BSP 89)

Evan Thompson, PhD

Embodied Cognition is a movement within cognitive science that argues that the mind is inseparable from the fact that the brain is embedded in a physical body. This means that everything that the brain does, from the simplest perception to complex decision-making, relies on the interaction of the body with its environment.  Evan Thompson's book, Mind in Life: Biology, Phenomenology, and the Sciences of Mind, is an in-depth look at what he calls the "enactive" approach to embodied cognition. The enactive approach was pioneered by Thompson's mentor Francisco Varela, and it emphasizes the importance of the body's active engagement with its environment.

In a recent interview (BSP 89) I talked with Thompson about some of the key ideas in Mind in Life. Unlike most episodes of the Brain Science Podcast, this is not really a stand-alone episode. It is part of my ongoing exploration of both embodied cognition and the controversial topic of emergence. It is also intended as a follow-up to my recent interview with Terrence Deacon.

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

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. The  Self 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.

Update on Consciousness Research with Christof Koch (BSP 84)

Christof Koch, PhD

The scientific study of consciousness was once viewed with skepticism, but this has changed dramatically in recent years.   According to pioneering neuroscientist, Christof Koch, "the great thing is we’re not condemned to just sort of philosophical speculation, but we can make some predictions, and then go out and measure them.  And those are the things I talk about in this book, Confessions of a Romantic Reductionist." In Brain Science Podcast #84 Koch reflects on the progress that has been made since I interviewed him back in 2007 (BSP 22), and he also talks about the latest initiatives at the Allen Institute for Brain Research, where he as recently become the chief science officer.

How Mind Emerges from Brain (BSP 82)

In his latest book, Who's in Charge?: Free Will and the Science of the Brain, respected neuroscientist, Michael S. Gazzaniga, explores how the discoveries of neuroscience impact how we see ourselves as human beings.  After providing a brief review of 20th century neuroscience, and even some of the work from the past decade, Dr. Gazzaniga concludes that nothing neuroscience has discovered changes the fact that "we are personally responsible agents and are to be held accountable for our actions."

Gazzaniga's position contrasts with those who think that recent discoveries show that the brain creates the mind in solely "upwardly causal" way, and who argue that since much of what our brain does is outside our conscious awareness or control, we should not be held responsible for our actions.  Who's in Charge?: Free Will and the Science of the Brain presents what I think is a convincing argument against this common position.

In the latest episode of the Brain Science Podcast (BSP 82) I present a detailed discussion of Dr. Gazzaniga's book.

Thomas Metzinger Explores Consciousness (BSP 67)

The free podcast version of Brain Science Podcast 67 is now available.  It is an interview with German philosopher Thomas Metzinger, author of The Ego Tunnel: The Science of the Mind and the Myth of the Self , and Being No One.   Dr. Metzinger argues that any credible model for how the brain generates the mind must incorporate unusual human experiences, such as so-called out of body experiences (OBE), and psychiatric conditions.  In this interview we explore how OBE and virtual reality experiments shed light on how the brain generates the sense of self that characterizes normal human experience.

How our Brain Creates Our World with Chris Frith, PhD (BSP 57)

frith

Episode 57 of the Brain Science Podcast is an interview with neuropsychologist, Dr. Chris Frith, author of Making up the Mind: How the Brain Creates Our Mental World.   Our brain processes information about the world outside us (via our senses) in the same way that it processes information from within our bodies and from our own mental world.  In this interview.  Dr. Frith and I explore the implications from recent discoveries about how our brain generates our mental world.

Neurophilosophy with Patricia Churchland (BSP 55)

pchurcland

Episode 55 of the Brain Science Podcast is an interview with highly respected philosopher Patricia Churchland.  Churchland is the author of Neurophilosophy and Brain-Wise.  She is currently on the faculty of the University of California at San Diego, and she was a featured speaker at the annual meeting of the Society for Neuroscience in 2008.

In this interview, we talked about neurophilosophy, which is an approach to philosophy of mind that gives high priority to incorporating the empiric findings of neuroscience.   We also talk about the evolving relationship between philosophy and neuroscience.   Churchland shares her enthusiasm for how the discoveries of neuroscience are changing the way we see ourselves as human beings.  We also talked a little about the issues of reductionism that I first brought up in Episode 53.

Review: "Did My Neurons Make Me Do It?" (BSP 53)

 Did My Neurons Make Me Do It?

Episode 53 of the Brain Science Podcast is a discussion of Did My Neurons Make Me Do It?: Philosophical and Neurobiological Perspectives on Moral Responsibility and Free Will, by Nancey Murphy and Warren S. Brown.  This book challenges the widespread fear that neuroscience is revealing an explanation of the human mind that concludes that moral responsibility and free will are illusions created by our brains.

Instead, the authors argue that the problem is the assumption that a physicalistic/materialistic model of the mind must also be reductionist (a viewpoint that all causes are bottom-up).  In this podcast I discuss their arguments against causal reductionism and for a dynamic systems model.  We also discuss why we need to avoid brain-body dualism and recognize that our mind is more than just what our brain does. The key to preserving our intuitive sense of our selves as free agents capable of reason, moral responsibility, and free will is that the dynamic systems approach allows top-down causation, without resorting to any supernatural causes or breaking any of the know laws of the physical universe.  This is a complex topic, but I present a concise overview of the book's key ideas.

Meditation and the Brain with Daniel Siegel, MD (BSP 44)

Daniel Siegel, M.D.

In Episode 44 of the Brain Science Podcast I talk with Daniel Siegel, MD about meditation and the brain.  Dr. Siegel is the author of several books including The Mindful Brain: Reflection and Attunement in the Cultivation of Well-Being.  In this interview, we review the scientific evidence about how mindfulness meditation changes the brain, both in terms of short term activity and in terms of long-term structural changes.  The evidence is convincing that a regular mindfulness practice can be an important element of brain health.

Show Notes and Links

Daniel J. Siegel, M.D.:

Scientists and writers mentioned in Episode 44:

  • Richard Davidson (University of Wisconsin): imaging studies of long-term meditators.
  • Sara Lazar (Harvard): imaging studies that show thickening of certain brain areas in long-term meditators.
  • Ruth Baer (University of Kentucky): studies mindfulness based therapies.

More information about meditation:

  • Spirit Rock  (Insight Meditation Center in northern California).

Note: Insight Meditation is based of vipassana meditation, the mindfulness practices of Theravada, the oldest branch of Buddhism.  Insight Meditation is easily adapted to secular purposes because it not based on beliefs or dogmas.  The most well-known secular form is called mindfulness meditation, which begins with a focus on breath awareness and then advances to developing compassion for oneself and others.

Researchers are studying people who practice other types of mediation also. Richard Davidson has focused his work on the study of Tibetan Buddhist monks.  Their practice emphasizes the development of compassion.

Review: "On Being Certain" (BSP 42)

Episode 42 of the Brain Science Podcast is a discussion of On Being Certain: Believing You Are Right Even When You're Not, by Robert Burton, MD.  This Part 1 of a two-part discussion of the unconscious origins of what Dr. Burton calls "the feeling of knowing."  In Episode 43 I will interview Dr. Burton. Today's episode provides an overview of Dr. Burton's key ideas.

In past episodes I have discussed the role of unconscious decision-making.  On Being Certain: Believing You Are Right Even When You're Not ,by Robert Burton, MD, takes this topic to a new level.  First, Dr. Burton discusses the evidence that the "feeling of knowing" arises from parts of our brain that we can neither access or control.  Then he discusses the implications of this finding, including the fact that it challenges long-held assumptions about the possibility of purely rational thought.

Embodied Cognition with Art Glenberg (BSP 36)

Art Glenberg, PhD

Episode 36 of the Brain Science Podcast is an interview with Arthur Glenberg, PhD, about embodied cognition.  Dr. Glenberg recently moved to Arizona State University, after over 30 years at the University of Wisconsin's Laboratory of Embodied Cognition.  His research focuses on the relationship between embodiment and language.  In this interview, we explore the experimental evidence for a theory of language that embraces the concept that our language abilities are actually rooted in our perceptual and motor abilities.  Dr. Glenberg also explains how his work has practical implications in helping children learn how to read.

Since Dr. Glenberg has had a long career as a working research scientist, this interview also provided an opportunity to explore how scientific hypotheses are formed and how experiments are designed to test these hypothesis.  I think this interview will give you a fascinating look into the real world of cognitive psychology.
