    brain, cognition, david wulff, psychology, psychology of religion, religion

    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?

  • Episode 16: Dopamine with Michael Frank

    July 3rd, 2019  |  Season 1  |  1 hr 22 mins
    brain, brown university, cognition, dopamine, genetics, michael frank, motivation, neuroscience

    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.

  • Episode 15: Speech Synthesis From Neural Signals

    June 17th, 2019  |  Season 1  |  47 mins 13 secs
    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.

  • Episode 14: Color, Concepts, and Design: Guest Karen Schloss

    June 4th, 2019  |  Season 1  |  1 hr 4 mins
    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:

    1. What color should recycling bins be?
    2. A tool that can help designers use color-concept associations in their work
    3. The "blueberry problem" (why is is that blueberries aren't very blue?)
    4. How to market a blue banana
    5. What color heaven and hell should be

    May 20th, 2019  |  Season 1  |  49 mins 34 secs
    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?

    Papers:
    "Evening use of light-emitting eReaders...."
    "Melanopsin: photoreceptors, physiology and potential"

    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....

    brain, ego depletion, self-control, willpower

    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.

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 something that would be considered life.
