perception

You perceive time as slower when you are afraid.

A 2007 study demonstrated that participants in high-arousal states, such as bungee jumping, overestimated the duration of temporal intervals.

The brain records more detail during high-arousal events, creating a richer memory trace. When you look back at that interval, the volume of data stored leads you to perceive that more time must have passed than actually did. You are experiencing a temporal illusion created by density of information.

Your perception of time is a function of emotional intensity.
