David Sobel, a developmental psychologist from Brown University, talks to us about the importance of play in learning. He has recently been collaborating with researchers around the country to investigate how children interact with exhibits in childrens' museums. One recent finding we discuss is that parent-child interaction styles can have a strong influence on what children learn.

conscious will, consciousness, free will, libet, neuroscience, philosophy, schurger
Guest Dr. Aaron Schurger talks to us about his research on the meaning of the "readiness potential", which has been referred to as "the brain signature of the will". Although this neural signal was already famous from research in the 1960s, it was Benjamin Libet's infamous experiments in the 1980s that proportedly showed that the readiness potential preceded an act of free will by a few hundred milliseconds. More recently (in press), Dr. Schurger and his colleagues have convincingly demonstrated that the readiness potential is not in fact predictive of an act of free will, but instead comes from a lack of a proper experimental control.

audiology, audition, brain, cognition, healthcare, hearing, hearing loss, mind, va
Dr. Erick Gallun joins us today to talk about the latest in audiology research, and how it can be applied to help those with a range of hearing problems. His research has focused on rehabilitation with Veteran's Association (VA) patients. Rapid-response medical care and an understanding of how hearing is affected by brain damage are critical areas in need of research. Advances in portable computing have made widespread assessment possible, and Virtual Reality applications show promise for cost-effective and standardized assessment.

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

asch, authority, brain, cognition, milgram, obedience, social psychology
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?

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.

brain, cognition, language, mind, speech, speech synthesis
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.

brain, cognition, color, concepts, design, neuroscience, psychology, recycling
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 is that blueberries aren't very blue?)
- How to market a blue banana
- What color heaven and hell should be

blue light, brain, eeg, melatonin, photosensitive retinal ganglion cells, sleep
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.
