David Wulff, author of the comprehensive "Psychology of Religion: Classic and Contemporary", talks with us today about some of the issues that psychologists grapple with in studying religion. How can a researcher take a fair and unbiased approach to a topic so fraught with issues of personal belief and faith? How important is belief anyway -- must one sacrifice the intellect to engage in religious practice? David discusses his recent research; his measure of religious tendencies, called the "Faith Q-Sort", has been used internationally to understand how religion manifests differently across individuals.

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 experiments

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!

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.

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:

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 regulation. We lay out the case....

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 Steven Wartman & Donald Combs.

Special Guest: Brent Stansfield.

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.
