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.

Well before we understand how brains work, we may find ourselves able to digitally copy the brain's structure and able to download the conscious mind into a computer. What are the possibilities and challenges?
In the wake of the Aurora movie theater shooting, many people had the same questions: What kind of derangement is indicated by the horrific acts of James Holmes? What is wrong with his brain? How will his mental state play out in the courts?
Our ignorance of the cosmos is too vast to commit to atheism, and yet we know too much to commit to a particular religion.

Find out why.
