CogNation

Discussions on the future of brain science and technology.

About the show

CogNation is a podcast by Rolf Nelson and Joe Hardy, two cognitive psychologists interested in the future of brain science and technology. We explore relevant topics in the areas of cognitive science, technology, AI, and philosophy. Although we dabble with dystopian implications of new technologies (such as the impending robopocalypse), we are led by our curiosity and try to keep it light and fun.

  • 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?)

    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. 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 something that would be considered life.
