Think about driving a route that’s very familiar.It could be your commute to work, a trip into town or the way home.Whichever it is, you know every twist and turn like the back of your hand.On these sorts of trips it’s easy to lose concentration on the driving and pay little attention to the passing scenery.The consequence is that you perceive that the trip has taken less time than it actually has. This is the well-travelled road effect: People tend to underestimate the time it takes to travel a familiar route. The effect is caused by the way we allocate our attention.When we travel down a well-known route, because we don’t have to concentrate much, time seems to flow more quickly.And afterwards, when we come to think back on it, we can’t remember the journey well because we didn’t pay much attention to it.So we assume it was shorter.
资料：Procrastination comes in many disguises. We might resolve to tackle a task, but find endless reasons to defer it. We might prioritize things we can readily tick off our to-do list- answering emails, say- while leaving the big, complex stuff untouched for another day. We can look and feel busy. while artfully avoiding the tanks that really matter. And when we look at those rolling, long untouched items at the bottom of our to-do list, we can't help but feel a little disappointed in ourselves.The problem is our brains are programmed to procrastinate. In general, we all tend to struggle with task that promise future upside in return for efforts we take now. That's because it's easier for our brains to process concrete rather than abstract things, and the immediate hassle is very tangible compared with those unknowable, uncertain future benefits. So the short-term effort easily dominates the long-term upside in our minds--an example of something that behavioral scientists call present bias.How can you become less myopic about your elusive tasks? It's all about rebalancing the cost benefit analysis: make the benefits of action feel bigger, and the costs of action feel smaller. The reward for doing a pestering task needs to feel larger than the immediate pain of tacking it.To make the benefits of action feel bigger and more real:Visualize how great it will be to get it done. Researchers have discovered that people are more likely to save for their future retirement if they're shown digitally aged photographs of themselves. Why? Because it makes their future self feel more real-making the future benefits of saving also feel more weighty.The next paragraph is probably about____.A.The natural function of our brainB.The other ways to make the benefits of action feel bigger and realC.The other ways to make the benefits of action feel smaller and unrealD.The perils of procrastination
