You have waited 45 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can 1 believe how fast time has passed. If you are 2 with this scene, you’ll know how time flies when you are having fun and 3 when you are bored. Now scientists have come up with a reason why this is the case.
Scans have shown that patterns of activity in the brain 4 according to how we focus on a task. When our time is occupied with 5 things, we concentrate more on how time is passing, which makes our brains think the clock is ticking more slowly.
In an experiment 6 by a French laboratory, 12 volunteers watched an image while researchers 7 their brain activity. The volunteers were told to first concentrate on how long a(an)
8 stayed on the screen, then focus on the color of the image, and thirdly, study both the 9
of time and color.
The results showed that the brain was 10 when the volunteers paid attention to more subjects. It is thought that if the brain is 11 , focusing on many aspects of a task, it has to spread its resources, and pays less attention to the clock. Therefore, time passes without us really 12 it, and seems to go quickly. If the brain is not so active, it devotes all its energies to monitoring the 13
of time, 14 creating the impression that time is dragging.
