CogNation

In the 1960s, the social psychologist Stanley Milgram performed some of the most famous experiments in psychology history, demonstrating that ordinary people could do terrible things in certain circumstances. Joe and Rolf look into the meaning of these experiments from a contemporary view. How are they holding up over 50 years later, and what else have we learned about obedience? Milgram's experim...

Dr. Michael Frank of Brown University talks to us about dopamine -- how it works in the brain, what his research has done to elucidate the function of dopamine circuits, and some of the genetics behind it. A really fascinating dive into a great topic! Papers: Dopamine and free will : Dopamine and learning :

Joe and Rolf discuss recent research finding that recordings from the brain can be used to reconstruct the speech that is being thought about. Getting into the prospects of mind-reading and other futuristic possibilities, they discuss some of the limitations of research in the area and what makes progress so difficult. Source material: Speech Synthesis from Neural Decoding of Spoken Sentences by G...

Our guest is Karen Schloss, who studies the way in which color is imbued with meaning through a lifetime of associations with objects (like bananas and fire trucks) and concepts (like love and politics). We discuss her research, including topics such as: What color should recycling bins be? A tool that can help designers use color-concept associations in their work The "blueberry problem" (why is...

We examine a paper that finds sleep disruption from using tablet computers (as compared to reading a book in dim light). How much should we be worried about the effects of screens on a good night's sleep? There's good reason to believe that blue light is the main culprit -- recently discovered receptors in the eye that respond to blue light directly connect to brain areas implicated in sleep regul...

Joe and Rolf talk with Brent Stansfield, who is currently the director of medical education at Wayne State University, about the future of health care and the kinds of value that doctors can provide as artificial intelligence and robotic surgery come of age. We frame the discussion around the article " Medical Education Must Move From the Information Age to the Age of Artificial Intelligence " by...

We talk about the history of research on intelligence. Is intelligence a real thing? What does it actually refer to, and can it be measured? Joe and Rolf discuss.

We discuss the article: Augmentation of Brain Function: Facts, Fiction, and Controversy ...a collection that explores recent research and opinion on ways of enhancing brain functioning, from classroom learning to the use of electrical and laser stimulation on the brain.

Is self-control something that we an think of as a resource that can be depleted and replenished? It's been a popular model in psychology for years, but it has come under question recently. We discuss "Why self-control seems like (but may not be) limited", a paper by Inzlicht and colleagues that proposes an alternate model.

Can we create life artificially? What would that even mean? Rolf and Joe talk about the field of Artificial Life, or "A-Life", which has worked toward the goal from a number of academic disciplines for the past thirty or so years. They think about different approaches, such as software, hardware, and biological artificial life, and consider what it might take to convince us that we have created so...

Dr. Stephanie Preston is our guest for this great conversation about the neural and evolutionary underpinnings of heroic behaviors. She proposes that heroism can be found across the phylogenetic spectrum, and acts of human heroism may have significant roots in conserved behavior patterns -- for example, the instinct for mother rats to retrieve and protect their young even at the risk of great pers...

The psychologist Dan Wegner (1948-2013) had a lot of influential work. One of his most popular (and controversial) claims was that conscious will is an illusion. He wanted to sidestep the issue of whether or not "free will" in a metaphysical sense exists, and get to the more psychological issue of why human beings have such a strong feeling that their conscious intention is what causes their actio...

We talk with Adrian Nestor, a professor and researcher at the University of Toronto, Scarsborough, about his recent research, the state of current brain imaging technology, and some speculations about where the field is headed. Can mental images and thoughts be captured, decoded, and understood by a combination of electroencephalography and machine learning techniques? What is the hype and what is...

Dr. Beatrice Golomb describes her paper, "Diplomats’ Mystery Illness and Pulsed Radiofrequency/ Microwave Radiation" which details the evidence for the theory that the Frey Effect is responsible for the Cuban embassy incident in 2016. She also details the (mis)handling of the New York Times story that popularized this claim as a leading theory of the incident.

Rolf and Joe tackle an interesting perceptual phenomenon called the Frey Effect. In the Frey Effect, first discovered in the 1960s, pulsed microwave beams can cause the perception of a high-pitched sound. This has come up in the news recently as an explanation of possible "attacks" on the American embassy in Cuba. How exactly does this work? Should it be something we should worry about? Discussion...

In this second part on brain-computer interfaces, discussion goes toward the more speculative. Joe and Rolf talk about Elon Musk's Neuralink project, which aims to fully connect brains with computers. Would this be possible? Could any system really read our thoughts in the way portrayed in science fiction? Should we even want this to happen? And most importantly, how does this affect the coming Ro...

In part A of the episode, Joe and Rolf base discussion around "Rapid calibration of an intracortical brain–computer interface for people with tetraplegia" by Brandman et al., thinking beyond the hype to get a realistic picture of how things work in the field. It's not all like The Matrix (yet).

Today on the show Rolf and Joe discuss the use of virtual reality for the treatment of mental health disorders like phobias and PTSD. They explore research from Dr. Skip Rizzo on the state of the art, discuss limitations of VR, and then engage in some wild and possibly irresponsible speculation.

In the inaugural episode of CogNation, Joe and Rolf talk about artificial intelligence that mimics the way people think. Along the way, they also talk about pneumatic tubes, uploading consciousness, and how we'll spend our time when robots do all the work. They touch on how this all inevetiably leads to robots taking over the world. The discussion is based around the article "Building Machines Tha...
