# Why does a clock counting down generate more pressure than a clock counting up?

Why does it seem that people feel more pressure with a clock counting down as opposed to counting up? Is there a specific term for this? Maybe counting down signifies some sort of loss whereas counting up signifies some sort of gain?

Is it really the case that counting down creates more pressure? Is there any evidence? – Jens Kouros Aug 7 '13 at 13:23
I would assume this is logical, because a clock counting down means a deadline. When it runs out, time's up. A clock counting up does not imply this necessarily. – Josh Gitlin Aug 16 '13 at 4:13
My guess is the following: It's much easier to get a grasp of how many time is left on the clock that runs down. You have less calculations to do to know if you're gonna make it in time. And as Josh says, there is the idea of 'losing' a resource when it runs down as opposed to accumulating it. – icosamuel Feb 19 '14 at 18:38
And it might be linked to the way we describe the "half-full" or "half-empty" water glass. Take a look at this TED talk. – icosamuel Feb 26 '14 at 15:24
