The Deceptive Watchman: How Our Brains Twist Time | 2014

A second doesn't always feel like a second—time can seem to slow down if you're riding a death-defying roller coaster, or speed up while you're having a night out on the town. But just what's going on inside our heads to skew our perception of time? Neuroscientists Lila Davachi, Dean Buonomano, David Eagleman, and Kia Nobre discuss findings from the latest scientific investigations into the intricacies of our internal clocks in "The Deceptive Watchman," a program in the Big Ideas series at the 2014 World Science Festival.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
