Resumen de When are you?
Westerhoff talks about the perception that people exist in the present. Sensory information reaches people at different speeds, yet appears unified as one moment. Nerve signals need time to be transmitted and time to be processed by the brain. And there are events--such as a light flashing, or someone snapping their fingers--that take less time to occur than their system needs to process them. By the time they become aware of the flash or the finger-snap, it is already history. People's experience of the world resembles a television broadcast with a time lag; conscious perception is not "live". This on its own might not be too much cause for concern, but in the same way the TV time lag makes last-minute censorship possible, their brain, rather than showing them what happened a moment ago, sometimes constructs a present that has never actually happened.
