Dr. Eugenie Scott on Teaching Evolution (B&I 21)

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.

Michael Arbib on Mirror Neurons (BSP 39)

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.

Art Glenberg discusses Embodied Cognition (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.

The Philosophy of Buffy the Vampire Slayer?

alan_saunders.jpg Alan Saunders of The Philosopher's Zone One of my favorite podcasts is an Australian Radio show called The Philosopher's Zone, but I have to admit that I was surprised to discover that host Alan Saunders shares my passion for the work of Joss Whedon, especially Buffy the Vampire Slayer. The March 29 episode is a discussion of the philosophical aspects of the BuffyVerse with James B. South who edited Buffy the Vampire Slayer and Philosophy: Fear and Trembling in Sunnydale (2003). The episode is called "Buffy the Concept Slayer," which is kind of a lame title, but it is still something Buffy fans will enjoy. However, it is not an episode someone new to the show will find very enlightening.

Natasha Mitchell interviews Jonah Lehrer about "Proust was a Neuroscientist"

The February 9th episode of All in the Mind is an excellent interview of author Jonah Lehrer about his book Proust was a Neuroscientist. In the interview Lehrer reflects on the danger of viewing science as the sole source of discovery, but he also talks a little about several of the people explored in his book. His basic premise is that artists from various fields often intuitively grasped truths that are now being revealed by neuroscience. One example is the insights that Proust had about memory. Proust was a Neuroscientist is a valuable contribution to the current exploration of the relevance of neuroscience to everyday life. It can be easily read in a few sittings or savored one artist at a time. Natasha Mitchell is an excellent interviewer because she always asks interesting and probing questions. (I think of her as the Australian Terry Gross.). All in the Mind is an excellent compliment to the Brain Science Podcast. Mitchell has recently begun an All in the Mind blog and there is a new All in the Mind group on Facebook.
