My lab focuses on how the mind percieves time during moments of crisis. We often hear that "time slows down" when we experience something like a fall from a roof, or a car accident. Why is this? See below for a number of media appearances where I discuss this phenomenon and what we think is really happening.

David discusses how time could very well be a construct of the human mind in this episode of "Through The Wormhole."

Listen as the guys at RadioLab bring the whole experience of free-falling, and how it seems to make time slow down, to life.


Here's an experiment in which my lab studied time perception by dropping volunteer subjects from a 150 foot high tower. Free fall. Subjects are going 50 miles per hour when they hit the net.

New Scientist magazine recently featured our time perception research as their cover story.
Why should the US invest in brain science? See David's opinion in the New York Times.
Barnes and Noble selected SUM as one of the Best Books of the Year.
David's iPad app "Why the Net Matters, or Six Ways to Avert the Collapse of Civilization" was recently called a "superbook" by the New York Times Magazine. For a taste of the argument, read David's article in WIRED or watch a video of his talk at the Long Now Foundation. Don't have an iPad? The manuscript is now available as an eBook.
