Why drive home felt shorter?

When flying from the moon to earth in 1969, astronaut Alan Bean, who is in the module of Apollo 12, felt a strange effect. "The drive home felt shorter," said Bean.

The story of this odd effect occurs not only in space. On earth, humans often feel the same. The journey to a place it felt longer than the trip back home, although the same trajectory taken away. The effect of this trip home was associated with memory and human experience.

Public opinion says man tried to identify areas that have never traveled. Brain recording identification signs along the road, such as monuments, tall trees, buildings, and traffic signs. This experience is generated on the way home, creating the effect of the way home. But the psychologist from Tilburg University, Netherlands, Niels van de Ven, denied that understanding.

"This effect also occurs when I drive by plane. When peering into the window, there's nothing that can be recognized," said Van de Ven.

Armed with doubts over the general assumption, he conducted experiments that explore these feelings. He asked two groups of cyclists journey to somewhere. On his way back, Van de Ven cyclists split into two groups. One group was asked to go home by taking the same path, while another group took a different path but have the same distance. If public opinion is correct, the group took home the same trajectory with the trip to experience a shorter travel time.

The experimental results are contrary to public opinion. Both groups are equally feel the way home noticeably faster.

From these results, Van de Ven until another explanation for the effect on the way home. According to him, humans are too optimistic when you start traveling. When the journey home, people expect a longer trip. An optimistic feel the trip takes longer, while for pessimistic way back noticeably faster.

"These effects arise due to expectations, what do you think will happen," said another psychologist from Elizabethtown College, Michael Roy. He felt the conclusions obtained from this latest experiment will not be widely accepted by other psychologists. Therefore, he acknowledged these new findings is not a single explanation for the effect of the way home. *** [NPR | ANTON WILLIAM | KORAN TEMPO 3640]
