We hear anywhere from 10 to 200 lies a day.
And although we’ve spent much of our history coming up with ways to detect these lies by tracking physiological changes in their tellers, these methods have proved unreliable. Is there a more direct approach?
Noah Zandan uses some famous examples of lying to illustrate how we might use communications science to analyze the lies themselves.
Steven Pinker is Psychologist, Cognitive Scientist, and Linguist at Harvard University
Here's a really interesting question.
How did humans acquire language?
In this lecture, best-selling author Steven Pinker introduces you to linguistics, the evolution of spoken language, and the debate over the existence of an innate universal grammar.
He also explores why language is such a fundamental part of social relationships, human biology, and human evolution. Finally, Pinker touches on the wide variety of applications for linguistics, from improving how we teach reading and writing to how we interpret law, politics, and literature.
Beau Lotto's colour games puzzle your vision, but they also spotlight what you can't normally see: how your brain works.
This fun, first-hand look at your own versatile sense of sight reveals how evolution tints your perception of what's really out there.
Russell Foster is a circadian neuroscientist: He studies the sleep cycles of the brain.
And he asks: What do we know about sleep?
Not a lot, it turns out, for something we do with one-third of our lives. In this talk, Foster shares three popular theories about why we sleep, busts some myths about how much sleep we need at different ages -- and hints at some bold new uses of sleep as a predictor of mental health.
The Brain and Reality
Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it.
How does this happen?
According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality."
Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence in this TedTalk.
