Ask three people to look out the same window at a busy street comer and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene, but each perceives  something different about it. Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow. For perception  is the minds' interpretation of what the senses -- in this case our eyes -- tell us. Many psychologists today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene. Psychologists study perception by   _  . A) setting up many experiments B) asking each other what they see C) looking out of windows D) studying people's eyes

Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear. Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting  and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation. Sarah Garfinkel at the Brighton and Sussex Medical School said: "Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart." The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, "The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see - and guide whether we see fear." To further understand this relationship, the scientists also used a brain scanner  to show how the brain influences the way the heart changes a person's feeling of fear. "We have found an important _ by which the heart and brain 'speak'to each other to change our feelings and reduce fear," Dr Garfinkel said. "We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those for those who may be suffering from serious stress disorder." What is the finding of the study? A) One's heart affects how he feels fear. B) fear is a result of one's relaxed heartbeat. C) fear has something to do with one's health. D) Ones fast heartbeats are likely to cause fear.
