GizExplains: Why Time Flies

Time flies when you ’re having play . But you ’re at work , and work sucks . So how is it 5:00 already ?

When we talk about “ lose time , ” we are n’t referring to that great night out , or that week of tremendous vacation , or the three - hour film that honestly did n’t feel like more than an hour . No , when we fret about not having enough time , or question where exactly all those hours go , we ’re blab out about mundane thing . The work day . A lazy , workaday Sunday . Days when we gave time no apparent reason to fly , and it flew anyway .

Why does that happen ? And where did all the fourth dimension go ? The secret lie in your brain ’s ticking clock — anelusive , inexact , and well ignorable clock .

First of all, yes

In translate any complex issue , especially a psychological one , suspicion does n’t usually get us too far . As often as you’re able to scrabble together a theory about how the psyche works , a serviceman in a laboratory coat will aline his glasses , cant forrad his brow , and deliver a carefully intoned , “ in reality … ”

But not today . Most of what you remember you know about the perception of time is true .

“ philosopher have spell on [ the perceptual experience of time ] for a tenacious menses , and psychological science has been concerned in it since its inception as a disjoined discipline — since the belated 1800s , ” explains Dr. Frederick M. Brown , Associate Professor of Psychology and Director of the Human Performance Rhythms Laboratory at Penn State University .

Brown articulate that common wisdom about how clip “ fly ” is basically correct . “ We do know that time can hale rather dramatically , and that when people get elderly , time seems to fly much faster . ” More broadly , “ When people are interested in something , they almost escape the metre dimension . ”

This jibe with common experience as well as tenner of experiment . What it does n’t do , though is excuse that in-between flat coat between bored and enthralled , when we ’re not having play , but we ’re not consciously hate life , either . This time seems to flee , too .

The cloak-and-dagger , Brown sound out , is something called habituation . This refers to the gradual adaptation to a stimulus or to the environment,“with a lessen reaction , ” and explains why sure virtuoso — the bitter of a lime , the pain of irritated efflorescence , the shock of a loud sound — seem to fall over time . But it can also help excuse , says Brown , how you could sometimes “ bunk the property of time”—by essentially losing awareness of it .

“ If there is a very regular noise — one that ’s observable but is not terribly noxious — after a while we tune it out . ” The hum of your computer , the bourdon of A / C , and muzak can all fade into the background . The chore of hear to these items defers to the affair that you are advisedly doing , in term of your attention .

The very act of thinking about metre — How long until lunch ? How long have I been here ? I ’m so bored!—has the tendency to make it feel as though it ’s passing more slowly . “ A see pile never boil ” is particularly apt here ; while it ’s sure as shooting bore to check water supply boiling point , the fact it has been informally codified as a Boring Thing make it even more boring . In this scenario , the importance of the human action ranks as follows : 1 . You ’re thinking about how long this seems to be taking . 2 . You ’re thinking about the water simmering . 3 . You ’re boiling water .

Or as Anthony Chaston of the University of Albertaputs it :

conceive of you had a piffling parry in your head , an inner clock , which most people believe the brain has , in some form . To monitor the passage of sentence , you sort of have to supervise , or add up , and count and collect those small clicks . Right ? You have to keep track of how many are going by . But if your attention is devote to a different task , like the ocular search chore , then you sometimes will pretermit the suction stop that come by .

On top of that , as Brown explicate , the inverse is reliable . “ When thing get irritating , like maybe the trickle of a spigot , you may actually become sensitized , then that becomes the focus of your care , so it ’s almost like you ’re waiting for the next drip mould , and you ’re not losing your sentience of awareness of the meter passing . ” substitute the “ trickle of a faucet ” with “ the objectionably humble project at hand , ” and you get the idea .

But why?

Now that we understand the ( super crude ) convention of Time Flight , we ’re left with a more fundamental question : Why the hellhole do our head play like this ?

It ’s easy to study people ’s percept of prison term , and lots of the great unwashed have . And they ’ve found all kinds of unearthly material :

• metre lapse more slowly to the great unwashed who are consciously keeping track of it than to the great unwashed who are n’t . ( The subject area inform half its participants that they ’d be asked about the length of the experiment , but not the other . )

• Body temperature can affect perception of meter . ( It passes slower when you ’re insensate . )

• Pulse ratedoes notaffect perception of clip .

• Drugs can do all kinds of terrifying / awesome thing to the perception of clock time . ( c.f . Our college years . )

• Certain wellness condition can do the same . ( An epileptic capture , for example , can experience as though its lasted a very long time , even if it was over in a matter of minute . )

Here ’s the problem : There ’s no light answer as to why these things affect the percept of time . We can talk generally about concentration and focus , but we ca n’t put a finger on what , in our brains , check this kind of stuff . Yet . In a paperpublishedin the Philosophical Transactions of the Royal Society of Biological Sciences journal , Marc Wittman explores dozens of potential causes , but arrives at this conclusion :

Despite the fact that metre is an indispensable factor for understanding complex deportment , the processes underlying the experience of prison term and the timing of action are incompletely understood .

In other watchword , we do n’t really know why this happen .

But we have a pretty good idea of how . So next time you enchant yourself wondering how it ’s five o’clock already , rest assured : whatever you were doing , and however long it seemed to take , at least you were giving it your exclusive focus .
