Many characteristics go into making human beings special — brain size, opposable thumbs, etc. Surely one of the most important is language, and in particular the ability to learn new sounds and use them for communication. Many other species communicate through sound, but only a very few — humans, elephants, bats, cetaceans, and a handful of bird species — learn new sounds in order to do so. Erich Jarvis has been shedding enormous light on the process of vocal learning, by studying birds and comparing them to humans. He argues that there is a particular mental circuit in the brains of parrots (for example) responsible for vocal learning, and that it corresponds to similar circuits in the human brain. This has implications for the development of intelligence and other important human characteristics.Support Mindscape on Patreon.Erich Jarvis received his Ph.D. in Animal Behavior and Molecular Neurobehavior from Rockefeller University. He is currently a professor in the Laboratory of Neurogenetics of Language at Rockefeller and an investigator at the Howard Hughes Medical Institute. Among his many awards are the Alan T. Waterman Award from the National Science Foundation, an American Philosophical Society Award, a Packard Foundation fellowship, an NIH Director’s Pioneer award, Northwestern University’s Distinguished Role Model in Science award, and the Summit Award from the American Society for Association Executives.Web siteRockefeller web pageGoogle Scholar publicationsWikipediaTalk on vocal learning and the brainTwitterSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Getting into the swing of things here with monthly Ask Me Anything episodes. If you missed the explanation last month, there is a Patreon page for people who wish to support Mindscape with a small donation per episode. Benefits include a warm feeling, social status, access to ad-free versions of the podcast, and the ability to ask questions once per month, which I answer over the course of a hilariously long podcast. Thanks to the generosity of Patreon supporters, we are now making the fruits of these monthly adventures available on the regular podcast feed.Here is the December 2020 edition. Note that there won’t be a January 2021 edition, as I take a break from podcasting for the holidays. Have a good one everybody!Support Mindscape on Patreon.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Those of us living in democracies tend to take the idea for granted. We forget what an audacious, radical idea it is to put government power into the hands of literally all of the citizens of a country. Where did such an idea come from, and where is it going? Political scientist David Stasavage has written an ambitious history of democracy worldwide, in which he makes a number of unconventional points. The roots of democracy go much further back than we often think; the idea wasn’t invented in Athens, but can be found in a large number of ancient societies. And the resurgence of democracy in Europe wasn’t because that continent was especially advanced, but precisely the opposite. These insights have implications for what the future of democracy has in store.Support Mindscape on Patreon.David Stasavage received his Ph.D. in Government from Harvard University. He is currently Dean for the Social Sciences and the Julius Silver Professor in the Department of Politics at New York University and an Affiliated Professor in NYU’s School of Law.

Aristotle conceived of the world in terms of teleological “final causes”; Darwin, or so the story goes, erased purpose and meaning from the world, replacing them with a bloodless scientific algorithm. But should we abandon all talk of meanings and purposes, or instead conceptualize them as emergent rather than fundamental? Philosophers (and former Mindscape guests) Alex Rosenberg and Daniel Dennett recently had an exchange on just this subject, and today we’re going to hear from a working scientist. David Haig is a geneticist and evolutionary biologist who argues that it’s perfectly sensible to perceive meaning as arising through the course of evolution, even if evolution itself is purposeless.Support Mindscape on Patreon.David Haig received his Ph.D. in biology from Macquarie University. He is currently the George Putnam Professor of Organismic and Evolutionary Biology at Harvard University. His research focuses on evolutionary aspects of cooperation, competition, and kinship, including the kinship theory of genomic imprinting.

Time! It doesn’t stop, psychological effects of being under lockdown notwithstanding. How we experience time depends on our situation, but time itself just marches forward. Unless, of course, it’s possible to travel to the past, as countless science-fiction scenarios have depicted. But does that really make sense? Couldn’t we then change the past, even so dramatically that our own existence would never have happened? In this solo podcast I talk about both the physics and fiction of time travel. I point out that it might be allowed by the laws of physics, and explain how that would work, but that we really don’t know. And I try to make sense of some of the less-sensible depictions of cinematic time travel. Coming up with a logical theory that could account for Back to the Future isn’t easy, but podcasting isn’t for the squeamish.Support Mindscape on Patreon.But wait, there’s more! I was contacted by Janna Levin, who we fondly remember from Episode 27. Janna moonlights as Chair and Director of Sciences at Pioneer Works, an institution dedicated to bringing together creative people in art and science. Like the rest of us, they’ve been looking for ways to offer more online content in these pandemic times, so we thought about ways to collaborate. Here’s what they came up with: artist Azikiwe Mohammed has created an animated video backdrop to this podcast episode. The visuals are trippy, colorful, and inspired by (without trying to directly illustrate) what I talk about in the episode. You can check out a brief write-up at the Pioneer Works site, or view the video directly below.https://www.youtube.com/watch?v=kHy1j4LiyGQSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

As you have likely heard me mention before, I have an account on Patreon, where people can sign up to donate a dollar or two per episode of Mindscape. In return they get two tangible (if minor) benefits. First, they get to listen to the podcast without any ads. Second, once per month I do an Ask Me Anything episode, where patrons are allowed to ask any question they like, and I do my best to answer as many as I can.Patreon supporters have kindly agreed to let these monthly AMA episodes be released to the general public (though they maintain the right actually ask the questions). I announced that I’d be doing this a while back, but with the cost structure I had with my podcast host it turned out to be prohibitively expensive for me. But now we’ve got that all figured out! So now, and hopefully going forward, these AMAs will be part of the regular podcast feed. They will be released sometime in the middle of each month, not as part of the usual Monday weekly series, so they won’t get numbers of their own.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Emotions are at the same time utterly central to who we are — where would we be without them? — and also seemingly peripheral to the “real” work our brains do, understanding the world and acting within it. Why do we have emotions, anyway? Are they hardwired into the brain? Lisa Feldman Barrett is one of the world’s leading experts in the psychology of emotions, and she emphasizes that they are more constructed and less hard-wired than you might think. How we feel and express emotions can vary from culture to culture or even person to person. It’s better to think of emotions of a link between affective response and our behaviors.Support Mindscape on Patreon.Lisa Feldman Barrett received her Ph.D. in psychology from the University of Waterloo. She is currently the University Distinguished Professor of Psychology and Director of the Interdisciplinary Affective Science Laboratory at Northeastern University. She also holds research appointments at Massachusetts General Hospital (MGH)/Harvard Medical School in the Psychiatric Neuroimaging Program and at the Martinos Center for Biomedical Imaging in the Department of Radiology. Among her many honors are the Award for Distinguished Service in Psychological Science from the American Psychological Association, the Mentor Award for Lifetime Achievement from the Association for Psychological Science, and a Guggenheim Fellowship.

Imagine you were locked in a sealed room, with no way to access the outside world but a few screens showing a view of what’s outside. Seems scary and limited, but that’s essentially the situation that our brains find themselves in — locked in our skulls, with only the limited information from a few unreliable sensory modalities to tell them what’s going on inside. Neuroscientist David Eagleman has long been interested in how the brain processes that sensory input, and also how we might train it to learn completely new ways of accessing the outside world, with important ramifications for virtual reality and novel brain/computer interface techniques.Support Mindscape on Patreon.David Eagleman received his Ph.D. in neuroscience from the Baylor College of Medicine. He is currently the CEO of Neosensory, a company that builds sensory-augmentation devices, as well as an adjunct professor at Stanford.
