为什么总感觉去程比回程久？“回程效应”告诉你

观看了两部电影之后，问他们感觉哪一部电影的时间显得时间长。观察往返旅程的人认为第二部电影的时长较短。有意思的是，看片时他们并没有感觉时间过得更快。

It was only when asked to compare the two films at the end of the experiment that the ‘return trip effect’ kicked in.The University of Kyoto researchers said that simply knowing we are on the homeward leg of a trip may make it seem shorter, when looking back.

只有在实验的最后阶段要求比较两部电影的时长时，“回程效应才起效。京都大学的研究人员称，回首旅程，只要知道我们踏上归程了，旅途似乎就会变短。

Previous studies have attributed to phenomenon to the effects of concentration and anticipation.It is thought that when we are going somewhere, we are focusing on getting there on time and every second counts.In contrast, when we are heading home, the pressure is off, we think of other things, and the journey passes more quickly.

以前的研究把这一现象归因于专注和期待效应。一般认为，我们外出去一个地方的时候，我们的注意力集中在准时到达，每一秒钟都至关重要。相反，归途中，我们没有了压力，会想些其他事情，旅途就过得快一些。

Another explanation is that we are too optimistic when we start to travel, leading to us under-estimating how long the trip will take.As a result, we are unnecessarily negative about how long the return journey will be and so are pleasantly surprised when it goes well.Interestingly, the effect isn’t due to a route being more familiar on the homeward leg.
