[Netease smart news April 30 news] A controversial study shows that reality may be based only on the human brain's expectations of the illusion. The study stated that the simulation of human psychology to the outside world depends on real data obtained from the senses only in a few cases. If this is the case, it means that each person's experience of "reality" is extremely different. According to New Scientist, scientists have published a series of research papers on an open portal called Philosophy and Predictive Processing. Most researchers believe that our perception of reality is based on information transmitted by the brain based on the eyes and ears. This process is called the "bottom-up" processing mode. However, the latest research suggests that reality is actually created in the human brain based on previous knowledge and experience, which in turn "influences" how we look at the world. This idea is called the "top-down" processing model. Because of this, our understanding of reality is actually mostly internal fiction. For example, when you pick up something, the weight you feel comes mainly from your brain's expectation of the object, not its actual weight. The evidence supporting this assertion comes from a previous study of how the brain perceives the illusion of "volume-weight." In the experiment, participants were given two balls, one big and one small, equal in weight. Researchers have found that people often mistakenly believe that the big ball is heavier. This phenomenon can be explained by the idea that "the human expectation of the world influences its view of reality." According to a research report by Wanja Wiese and Thomas K. Metzinger of the University of Johannes Gutenberg in Mainz, Germany, “the perception is driven by the top-down processing model†is not new (though it does not Denies the fact that mainstream cognitive theory has long been marginalized." “The new contribution of predictive processing theory lies in its emphasis on this point of view, which describes the top-down processing model and the influence of existing knowledge as the salient features of the perceptual process. These features do not appear only in perceptual input. But it always existed." Researchers say that the brain constantly monitors new changes in the body and its surroundings, which makes a reasonable guess as to what will happen next. The predictions that the brain considers to be the most realistic are then given priority. They also believe that "a person's brain constantly makes statistical predictions that are representative of the current external world and that these predictions are organized in a hierarchical structure." Researchers believe that human predictions about what they should see are based on a range of factors, including our personal experiences and emotional states. Related background: A test that may prove reality is fantasy If you close your eyes and stop watching it, the universe will cease to exist. This assertion is based on the well-known theory in quantum mechanics that believes that the past behavior of a particle will change according to what we see (different). Last year, scientists did an experiment and proved that this theory is correct at the atomic level. According to the rules of quantum mechanics, the boundary between the “outside world†and human subjective consciousness is blurred. When physicists study atoms or light particles, what they see depends on how they set up their experiments. To test this, the physicists at the Australian National University recently conducted a test called "John Wheeler's Delayed Choice Thinking Experiment." In this experiment, a moving object was given the right to choose whether to move like a particle or a wave. Wheeler's experiment then asks: At what moment does the object make a decision? Common sense tells us whether the experimental object is wavy or granular. This has nothing to do with our measurement method. However, quantum physics theory predicts whether people observe whether wavy or granular behavior actually depends only on how the experimental object is measured at the end of its journey. This forecast was confirmed by the Australian research team. "The experiment proved that everything that determines everything is actually a measurement. At the quantum level, if you do not look at it, the reality will cease to exist," said Associate Professor Andrew Truscott. (Source/Dailymail Compiler/Equipment/Ecale) 燑br>
