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.
Listen to David discussing Sum -- and actor Jeffrey Tambor reading stories from the book -- on WNYC's Radiolab.
SUM has been turned into an opera at the Royal Opera House in London (Composer: Max Richter, Director: Wayne McGregor). The London Evening Standard hails the opera as "immersive, meditative and sweetly fascinating". Read about the background of the collaboration in Wired.
SUM was chosen as the best book of 2009 by Chicago Tribune's Pulitzer-winning literary critic Julia Keller.
