Brain Science Podcast #42: "On Being Certain" Part 1


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.

Brain Science Podcast #41: Interview with Linguist Alice Gaby


Episode 41 of the Brain Science Podcast is an interview with Alice Gaby, PhD, from the University of California-Berkeley. Dr. Gaby is a linguist who studies the role of language in cognition as well as the aboriginal languages of Australia. In this episode Dr. Gaby introduces some of the basic areas of linguistics. We also talk about why linguistics is important to understanding brain function, as well as the importance of interdisciplinary communication to advancement in both fields. Dr. Gaby's infectious enthusiasm makes this potentially intimidating subject accessible to everyone.

Books and Ideas Podcast #21: Interview with Eugenie Scott

Eugenie Scott, the Executive Director of the National Center for Science Education, was interviewed in Episode 21 of Books and Ideas. The focus of our conversation was the importance of teaching evolution in the public schools. Dr. Scott and the NCSE have worked for over 20 years to promote the teaching of evolution because it is an essential component of a modern education in the life sciences. Unfortunately, nearly 150 years after Darwin's On the Origin of Species (1859) many Americans still reject this fundamental idea and much of Scott's work is focused on trying to keep creationism and so-called Intelligent Design out of school curriculum.

Recently the NCSE launched a very valuable site called Expelled Exposed, which focuses on exposing the many inaccuracies presented in Ben Stein's recent pro-intelligent design "documentary" Expelled. One of the things that has come out in numerous interviews is that the producers of the film mislead all the pro-evolution guests that appear in the film. We discuss this briefly near the end of the interview, but it was not the focus of our discussion. (see below for more links regarding Expelled)

Since Dr. Scott has been interviewed about Expelled and Expelled Exposed on several other podcasts, I wanted to focus our interview more on the importance of accurate science education. Also, we discussed the fact that despite the claims of right-wing fundamentalists there are many Christians and people of other faiths who accept the theory of evolution as scientifically valid. Accepting evolution does not mean one is choosing atheism. I think this is a very important distinction because while atheists are outspoken in their support of evolution they represent a small minority. I was encouraged to learn from Dr. Scott that the NCSE is working closely with religious leaders and scientists of faith to try to educate their members.

Since Books and Ideas reaches an international audience I thought that it was important that we discuss the origins of the evolution versus creationism controversy, which is unique to the United States. Scott does an excellent job of explaining how our unique religious heritage along with our locally controlled school systems combine to create a situation that most of the world find's rather mystifying. Her book Evolution vs. Creationism: An Introduction also provides an excellent overview of the subject from both an historical and scientific prospective.

Finally, we talk about the importance of evolution as a basic idea in modern biology. While we didn't dwell on this, I think we are both concerned about the implications for the future if a majority of young Americans are reaching college without a solid foundation in the principles of evolution. We also talked about why intelligent design fails to meet the basic definition of a scientific theory since it provides no testable hypotheses. Dr. Scott also provides a excellent review of the basic writings for those who want to learn more.

Brain Science Podcast #39: Michael Arbib on Mirror Neurons

Episode 39 of the Brain Science Podcast is an interview with Dr. Michael Arbib from the University of Southern California. Dr. Arbib's work with functional brain imaging has established the presence of mirror neurons in the human brain. In our interview we focused on the role of mirror neurons in imitation and language. In particular I questioned Dr. Arbib about the Mirror System Hypothesis (MSH) of Language Evolution that he proposed in 1998 with Giacomo Rizzolatti. We also explored how this hypothesis diverges from the universal grammar proposed by Noam Chomsky. Dr. Arbib also shared his enthusiasm for future research and we talked about the special challenges caused by the interdisciplinary nature of modern neuroscience.

Brain Science Podcast #38: Interview with Jeff Hawkins

Episode 38 of the Brain Science Podcast is an interview with Jeff Hawkins, author of On Intelligence. Hawkins is well-known for founding Palm Computing and Handspring. He invented the Grafitti handwriting recognition system and helped develop the Palm Trio SmartPhone. Since he published his bestseller On Intelligence, he has devoted his work to his passion for neuroscience. His current company Numenta is developing software that models the hierarchal structure of the neocortex. In this interview we talk about the ideas in Hawkins book and how he is applying them to develop a computer model of cortical function. This is a follow-up to Episode 2, which first aired in December of 2006.

Brain Science Podcast #37: Brain Rules with John Medina

Episode 37 of the Brain Science Podcast an interview with Dr. John Medina, author of Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School. We talk about how exercise, sleep, and stress effect our brains with an emphasis on practical advice for healthier brain function. We also look at how research on memory, vision and the brain's attention system suggests how we can improve our ability to learn and our ability to share ideas with others.

Dr. Medina's focus is on considering real world examples of how our schools and work environments could be reformed to utilize the growing knowledge of neuroscience. But he also stresses the importance of compiling sufficient experimental data before embarking on new programs.

Brain Science Podcast #36: Embodied Cognition with Art Glenberg

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.
