There is a word called "seeing is believing", said is hearsay not credible, his eyes to see it is always true. This argument is tenable in intuition: eyesfaithfully reflect all of the objective world, whether it is the perception of object, or the perception of object motion. It can be said is the most basic common sense: most of the activities in daily life we are asking for things outside awareness is very precise, slight mistake could be fatal. Thereforethe evolution of human visual system of super developed, guaranteed tofaithfully reflect the rich world.However, many psychologists believe that in fact the eyes and vision systemis not our absolute objective: seeing is not necessarily a real. A recent study by the California Institute of Technology professor found that USA,visual information is given by the observer's subjective factors. In this study,the researchers stood in the campus at the bottom of a slope, inclinationand then let students estimated from the mountain. The students have two kinds of estimation method. The first way is to let the participants looked atthe hillside, and then make a board edge is placed into the parallel to thedirection of the hillside to estimate the gradient of the slope. Another way is to let the participants do not look at the hillside, and then use the same wayto estimate the slope of the hill.In the first estimation way, participants relied more on visual cues. In this case, the subjects usually overestimate the gradient of the slope, will put aabout 31 degree slopes as about 50 degrees slope. However, when subjects no longer see hill, estimation of subjects is very accurate. Even more surprising is that in the first case, the subjects overestimate will with the subjects state and more serious. Especially the subjects had just attended the race, carrying a heavy backpack, or physical weakness and aging. These subjects were estimated when not watching the hillside oraccurate.Through the results, the researchers found a law: that is, when the participants felt body state is more difficult to deal with this slope, they tend to estimate hillside steeper, and this strategy is no consciousness reflected in the visual system was tried in the. That is to say, our vision is notcompletely objective, but reflects the psychological state of the subjects in a certain extent. This may also explain the ancient Chinese Ji Chang learningarchery, after a long time of training, can put the lice looked more and morelarge. This strategy can help people to better cope with the difficulties, to complete the task, so have to say is the natural choi
