You have waited 45 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can’t 36 how quickly time has passed.
If you are familiar with this 37 , you’ll know how time flies when you are having fun-and 38 when you are bored. Now scientists have 39 a reason why this is the case.
Scans have shown that patterns of activity in the brain 40 according to how we focus on a task. When we are 41 , we concentrate more on how time is passing. And this makes our brains 42 the clock is ticking more slowly.
In an experiment 43 by a French laboratory, 12 volunteers watched an image 44
researchers monitored their brain activity.
The volunteers were told to 45 concentrate on how long an image appeared for, then
46 the color of the image, and thirdly, study both duration and color. The results showed that 47 was more active when the volunteers paid 48 subjects.
It is thought that if the brain is 49 focusing on many aspects of a task, it has to 50 its resources, and pays less attention to the clock. 51 , time passes without us really 52 it, and seems to go quickly. If the brain is not so active, it concentrates its 53 energies on monitoring the passing of time. 54 , time seems to drag.
Next time you feel bored 55 , perhaps you should pay more attention to what the teacher is saying!
