Have you noticed that time seems to pass more slowly when you're waiting in a long line? But when you're playing with your friends, hours seem like minutes. Of course, time is always passing at the same speed--but why does it sometimes feel different?
A study published in the Journal of Neuroscience (神经科学杂志)can tell us the answer. Lead author Masamichi Hayashi and his research team in the US found that it has to do with neurons(神经元)in our brains that are sensitive(敏感的)to time.
The researchers measured (测量)the brain activity of 18 adults who were asked to look at a picture on a screen for a certain period of time. They were then asked to guess how long they had been looking at the picture. They were likely to guess incorrectly when they were asked to stare at the picture for very long or very short periods of time.
After looking at their brain activity, the researchers found neurons need a certain amount of time to pass signals. When they receive repetitive stimulation(重复的刺激) (such as staring at a screen), these neurons finally get tired and don't work well. It doesn't matter whether this amount of time is long or short, as long as the stimulation is repetitive. However, other neurons still work normally, causing a different experience of time.
When you stand in line or do some other repetitive tasks, such as math homework, your time-sensitive neurons get tired and cause you to feel like time is going slowly. But when you're doing something more high-speed, such as playing soccer, you experience in the opposite way. Either way, you can't always trust your brain when it comes to your experience of time.
