What can neuroscience teach us about AI, and vice versa, what can AI teach us about our own intelligence? Joe and Rolf talk to returning guest Daniel Sternberg about advances in AI over the past year. Topics include using the methods of cognitive psychology to understand AI; representation in artificial intelligence; what current large language models  (LLMs) are good at and not good at; sentience in AI; the future of humanity; and other important stuff. Natural and Artificial Intelligence:...

This episode is dedicated to the memory of colleague and friend Grace Baron [https://wheatoncollege.edu/news/no-time-like-now/]. Joe and Rolf talk to Dr. Matthew Goodwin, a professor at Northeastern University whose research focus is on autism. His most recent paper [https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2813185] used biosensing (heart rate, skin conductance, etc.) to predict aggressive behavior in profound autistic individuals up to three minutes before the event. 

Joe and Rolf discuss the ideas of perceptual psychologist Donald Hoffman, who has argued that our perceptual systems have no access to reality, since evolution is driven by fitness functions, not objective truth. He has also argued that our perception is a user interface (like a desktop on a computer, or a VR headset), and that objects such as the moon don't exist when we are not apprehending them.   Hoffman, Donald. The case against reality: Why evolution hid the truth from our eyes. WW...

Neil Markey, a veteran of Iraq and Afghanistan, used meditation for years to deal with depression and PTSD. He is currently CEO of Beckley Retreats, a group that runs retreats to Jamaica and the Netherlands for guided psychedelic experiences.

You can find links to his published research as well as a series of videos on harm reduction at the following...

Joe and Rolf discuss new work in neural interfaces that is helping paralyzed individuals communicate. Based on the recent Nature article: Metzger, S. L., Littlejohn, K. T., Silva, A. B., Moses, D. A., Seaton, M. P., Wang, R., ... & Chang, E. F. (2023). A high-performance neuroprosthesis for speech decoding and avatar control. Nature, 1-10.

Rolf and Joe discuss two philosophical theories of the self, Bundle Theory and Ego Theory, based on a paper by Derek Parfit. They return to the topic of the teletransporter, and although Joe is happy to go through the teletransporter, Rolf is convinced it means certain death. Parfit, D. (2016). Divided minds and the nature of persons. Science Fiction and Philosophy: From Time Travel to Superintelligence, 91-98.

In this episode, CogNation goes to the Psychedelic Science conference in Denver to get in on all the excitement. We present four interviews from the conference that represent a range of ideas about the resurgent interest in psychedelics as therapeutics. Bekely Waves The East Institute Balasz Szigeti Manoj Doss

Everyone has a set of beliefs. Increasingly, it seems like we wonder how so many people can hold opposite or contradictory beliefs -- puzzling if we think there's an objective reality. We have a great conversation with Mark Solomon, a clinical psychologist and the host of the Being Reasonable podcast, about Street Epistemology, a conversational method of probing why we believe what we believe. https://www.beingreasonableshow.com/ https://www.youtube.com/@BeingReasonable Special Guest:...

Manesh Girn talks to us about the effects of psychedelics on the brain, based on his recent paper, "A complex systems perspective on psychedelic brain action". We discuss the current state of psychedelics as therapeutics, and how information theory can model changes in brain states that result from taking psychedelics. Special Guest: Manesh Girn.

We talk with Professor Gail Sahar about her new book, entitled "Blame and Political Attitudes: The Psychology of America's Culture War", where she applies social psychology to understand where and why we assign blame in the political sphere. https://www.amazon.com/Blame-Political-Attitudes-Psychology-Americas/dp/303120235X

We talk to Dr. Daniel Sternberg, head of data at Notion Labs, about how to understand new developments in AI (artificial intelligence) like DALL-E-2 and chatgpt. Topics include the possibility for general intelligence in AI, similarities between human cognition and generative AI models, and the potential for sentient AI.

Stephanie Preston (University of Michigan) returns to the show to talk about her latest research. Why do we hoard stuff? And how can we get people to care about the consequences of all that stuff on the environment? Her research has taken her from the strategies that some rats use to hide seeds (some hide in lots of small caches, while others hoard in a single location), to the cognitive/neural/emotional mechanisms of human beings with hoarding disorder. People tend to have emotional...

Joe and Rolf talk to Dr. Aric Prather, a clinical psychiatrist at UCSF and author of the new book "The Sleep Prescription: Seven Days to Unlocking Your Best Rest" about why sleep is important, the relationship of stress to sleep, and how to tune your body and environment to get a great night's sleep. Special Guest: Aric Prather.

Is self-control at age 4 a predictor of lifelong success? Rolf & Joe look at new studies that replicate and extend Mischel's marshmallow experiments, discussing why some kids can wait longer for a bigger treat and what the test itself means.

Our guests, Dr. Sheila Macrine and Dr. Jennifer Fugate, discuss the concept of "embodied cognition" and its implications for the classroom. They argue that traditional cognitive psychology has ignored the fact that the brain is situated in the body, and that learning happens most effectively if it is connected with our body and our environment, rather than learned abstractly.

Developmental psychologist Matthew Gingo joins to discuss his research on morality and deception. Why and under what circumstances do parents and their children lie to one another? We discuss his paper entitled "What they don't know won't hurt them: Parents' judgments about lying to their adolescents", published in the Journal of Research on Adolescence (2019)

Joe and Rolf once again scry the future with bold and entirely accurate predictions about the year 2022

Joshua Miele is a blind scientist and inventor living in the Bay Area. Amongst his many initiatives is the Blind Arduino Project, where participants learn how to navigate a world of maker electronics that are really designed for the sighted. He talks to Joe and Rolf about his work to bring accessible and useful tools to the blind community. He teaches blind soldering classes, and he has worked to make braille maps easily accessible. He discusses what technology in recent years has helped the...

In Annie Murphy Paul's new book, "The Extended Mind", the philosophical idea of our minds extending beyond the physical boundaries of the body are explored. Rolf and Joe talk to Annie about the implications of this idea, and how it might be used to improve the way we think in a number of contexts. Special Guest: Annie Murphy Paul.

The NIH Toolbox is the result of an ambitious project supported by the National Institutes of Health to develop a comprehensive, standardized, and highly accessible test battery to be used in research. Dr. Julie Hook is the Product Manager for the project and is in large part responsible for the development of the Toolkit. Rolf and Joe discuss with Julie a wide ranging set of topics related to the science of cognitive, sensory, and motor testing, including some of the core design principles...

Bestselling author known for making complex topics accessible to readers, Tom Vanderbilt's recent book is Beginners: The Joy and Transformative Power of Lifelong Learning. Rather than buying into the idea that learning is for kids, Tom takes the "beginner's mind" to challenging new skills, such as singing, juggling, and jewelery making, where he starts at ground zero and works to achieve a level of competence. Rolf, Joe, and Tom discuss the value of learning for its own sake, brain...

Enough with 2020. Rolf and Joe present their predictions for what lies ahead in 2021.....
