"How the Brain Stops Time"

11.05.10


"One of the strangest side-effects of intense fear is time dilation, the apparent slowing-down of time. It's a common trope in movies and TV shows, like the memorable scene from The Matrix in which time slows down so dramatically that bullets fired at the hero seem to move at a walking pace. In real life, our perceptions aren't keyed up quite that dramatically, but survivors of life-and-death situations often report that things seem to take longer to happen, objects fall more slowly, and they're capable of complex thoughts in what would normally be the blink of an eye.

(...)

Eagleman reasoned that, if fear really does speed up our rate of perception, then once his subjects were in the terror of freefall, they should be able to make out the numbers on the display.

As it turned out, they couldn't. That means that fear does not actually speed up our rate of perception or mental processing. Instead, it allows us to remember what we do experience in greater detail. Since our perception of time is based on the number of things we remember, fearful experiences thus seem to unfold more slowly."
