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.
设想开车行驶一条你非常熟悉的路线。那可能是上班的，进城或回家的必经之路。无论是哪条路，你都会对它的迂回曲折了如指掌。在这样的行驶中你很容易将精力集中在驾驶上而忽视路过的风景。结果，这就使得 你会认为行驶路程应该比它实际上需要的时间少。 这就是熟悉旅途效应：人们趋于低估熟悉路程的所需时间。 我们的注意力分配情况导致了这种效应。当我们在我们非常熟悉的道路上行驶时，由于不需要太集中精力认路，所以时间似乎过得很快。而且事后，当我们试图回忆这个旅程时也不怎么能记得清楚，因为我们确实没有关注太多。所以我们就想当然认为路程是短了一些。
