The brain of the optimistic one " Hold back unpleasant information "
London, October 10 (Xinhua) ' The reporter is yellow) . A latest research in Britain reveals, this kind of optimism is really " born " ,it have a partiality for at being at process information the because they one brain, " hold back unpleasant information " natural . The researchers of organizations such as British London University institute,etc. are in new one to say on magazine of " neural science that naturally ", they ask some volunteers to participate in testing the test that this kind of brain has a partiality for. The volunteer reads a series of negative incident first, for instance burglary or disease,etc., then assess the probability happening on oneself in these incidents. Researchers will tell volunteers the average probability that this incident happens later, replay the dependent event again, ask volunteers to assess them and happen in one's own probability on one's body again. The result reveals, if what experimenters begin is estimated to be more pessimistic than average probability, see the brain receives good news, will revise one's own estimated value by a wide margin after average probability; But if estimation that begin optimistic than average probability, average probability that provide equivalent to bad news, range but and big which the brain thereupon revises. Take cancer as examples, if experimenters begin to think that it is 40% to suffer from cancer probability by oneself, after knowing that real average probability is 30%, will thereupon adjust one's own estimation to 32%; But if begin to estimate that suffers from only 10% of cancer probability by oneself most, would rather not heighten estimated value very much. Though it all have this kind that experimenters are overall " Hold back unpleasant information " Inclination,but at optimism do very well. Researchers have judged experimenters' optimistic inclination with the psychological questionnaire in addition, accept, scan the intersection of brain and activity situation of frontal lobe with the intersection of magnetic resonance imaging and technology test, while being above-mentioned in them. The frontal lobe is the position to run with relevant information. The result reveals, while receiving good news, all people's frontal lobes are very active, but when being received bad news, the intensity that the frontal lobe move is not quite alike, the activity intensity of the frontal lobe of the optimistic one is particularly low, demonstrate their brain hopes naturally " Filter " Lose bad news, it is minimum too that the optimistic one adjusts the range that oneself estimates on the basis of bad news finally. Researchers tower favourable Sharrotts say, it has some advantages that optimistic, such as the optimistic one being often seldom anxious, the psychological health is better; But harmful, for example will take the precautionary measures for the possible risk less, in case the consequence takes place seriously. So, optimistic relates to inherent activity characteristic of brain, people should assess the risk as correctly as possible.
