Why time slows down




















In psychology, researchers often posit that there is such a clock, namely a pacemaker emitting pulses, and the accumulation of these pulses determines the experience of time, the impression that a time interval is short or long.

Any event having an effect on arousal, as is the case for instance with events provoking emotions like joy or fear, is susceptible to disturb time perception. There are other situations where time seems to fly. The key ingredient of this impression is attention. But if you are busy doing a pleasant activity, you will not see time passing. This effect of attention on time perception is one the most repeated finding in the timing and time perception literature. If you have a cognitive task, not necessarily pleasant, that captures your attention during a given period of time, you will find this period to be short, shorter than if you would have had no activity during the same period.

In other words, the accumulation the pulses referred to above is under the control of attentional mechanisms. Time is also crucial, under one form or another, in different pathologies. The relation to time may also be distorted on a larger scale. Anxious people, more than others, will have the impression, that a given distance in the future is close, a tendency that goes in the opposite direction for depressed people who are inclined to be turned towards the past. On an even large scale, we sometimes feel that time is now passing faster as we get older.

The fact of being so busy at some period of life may lead to the impression that, at the end of a given week, not as much as planned or expected at the beginning of that week was done.

The repetition of such impressions may lead to the impression that time passes faster than it used to, when there was less to do during childhood. Indeed, this is one of several hypotheses for explaining this impression that life is passing faster as we get older. This overall impression may also be related to the accumulation of occasions where we find ourselves so surprised that a given event occurred so long ago.

When you are 8, nothing happened 10 years ago; but when you get older, you may have some vague impression that an event happened 8 or 10 years ago, while this event may have happened 20 years ago. Professor, Mechanical Engineering, Duke University, who has recently researched the question of why days seem shorter as we get older. My work is physics, and the physics of this are very simple. The process is staccato, jerky, like a horse-drawn buggy on a bumpy road. These discrete images travel from the retina to the brain, in a flow of electrical signals.

That travel is facilitated by a link—the link between the retina and the brain—and it has a speed. With age, as the body grows, the length of those links, and the distance between the retina and the brain, increases; meanwhile, as one ages further, the speed of these signals decreases, as the body degrades. This is why an aging person feels like life is rushing by. But there are things you can do to change this process. One would be to experience more images worth clicking or recording with your eyes—by doing different things, avoiding routine, avoiding being an automaton.

It pays to get off the couch. Voluntary and involuntary changes in our internal state have a strong influence on timing and time perception in the hundredths of milliseconds-to-hours range. Our internal state can be modulated by neurobiological, psychological, and environmental factors, and most often it is some combination of all three. Take the example of a hungry individual waiting for their food to come at a restaurant.
