What I want is always farther than expected, the effect of desire to make my sense of distance go wrong

Humans areBinocular disparityIt is possible to perceive the distance to the object by the experiment which examines the influence of the desire on the human perception, and it became clear that the thing which I want is seen to be closer than the actual thing .

There is a word "victory without desire", but if you do not think that you want the premium especially in the ring-through of a fairytale etc., it may be easier for a person to grasp the distance to the target correctly and succeed.

Details are as below.Objects we want are seen as closer

Psychological ScienceIt was announced in the magazineNew York UniversityOf psychologyEmily BalcetisAssociate ProfessorCornell UniversityofDavid DunningIn the research conducted by a professor, we first conducted an experiment in which subjects were asked to measure the distance to the bottle containing water. Subjects were divided into two groups, one group had water before the experiment and another group had a salty pretzel without drinking water. As a result, the subjects thirsty by the pretzels compared with the subjects who drank the water, we observed that the bottle is nearby.

Next, in another experiment, we played a game of throwing a beanbag and putting it on a gift card. There are two kinds of cards, 0 dollars and 25 dollars (about 2250 yen), and subjects can get the card if they are on the gift card. As a result, when the card was $ 25, compared to the case of $ 0, Odama had a tendency to landing before the card. In other words, in the subject's eyes it seemed that the card was closer than $ 0 if the card was $ 25.

From this research it can be said that when a person traveling in the desert finds an oasis or when a person drifting the sea finds a land, the oasis and the land are often farther than it was visible. Although it seems to be severe, if it seemed as if the aiming place seemed to be far from the actual thing, there is no possibility of giving up there aiming there and there is a high possibility that it gives up, on the contrary it can be seen closer than the actual thing Well, maybe you will feel like "Let's do it a little more".

Humanity and the ancestors of the era when hunting and gathering living were supposed to be easy to chase if prey could be seen in the nearby, and it was easy to feel like going for taking if food such as fruit can be found nearby So, it seems that the mechanism that "I want the things near you" worked advantageously for survival.

It may be said that human beings have a mechanism not to give up what they want, or people who did not give up what they want in the evolution process have survived.
