Are your memories fake?

  There are some false memories in the brain. So why are these false memories? How many memories do people have false? Will false memories make the suspect confess to a murder he has never committed? Let us solve the mystery one by one.
  Imagine that the police suddenly came to you and told you: When you were a teenager, you committed a crime. Now you are under arrest. The police ask you to tell what happened. But you deny this matter, not because you are dishonest, but because you can’t remember such an event in your life.
  However, the police in charge of the investigation took out a thick pile of supporting documents, which included the testimony of others, and even the testimony of your parents, which seemed to confirm your crime. You start to wonder: Has such a thing really happened? Especially when a psychologist sits opposite you, trying to ease your emotions, and telling you that it is normal for you not to remember the sins you have committed, because your subconscious mind is hiding the truth. Now your self-confidence is broken-oh, it seems that something like this has indeed happened.   Don’t think that the
  implanted “memory”
is impossible. Julia Shaw, a psychologist at the University of Bedfordshire in the United Kingdom, and her colleagues have successfully used this method in their experiments-“implanting” false memories into volunteers, with a success rate of 71% . Incredibly, they not only implanted false memories, but also allowed some volunteers to admit to crimes they had never committed. The volunteers only needed to talk to the psychologist three times (40 minutes each time) from denying it at the beginning to confessing it later!
  One of the young women “confessed” the process of attacking another girl with a stone when she was 14 years old: “I remember that the stone hit her on the head and the blood flowed. There were police officers here, and two of them. I’m sure of this…” The woman faced the camera and admitted that this was the “crime” she committed 5 years ago.
  The truth is that this incident has never happened, it was fabricated by psychologists during the experiment. So why did these volunteers deny these false memories at first, but finally believe them? To know this, we must carefully study the function of the brain.
  Brain memory like editable pages
  Many people believe that the human memory is like a video camera, we can see and hear things correctly and completely recorded. In this way, we can view the video later and review what happened at that time. Or to put it another way: if we experience something and leave a memory of it, the memory will never change. ——If you think so, you are wrong.
  Researchers at the University of California in the United States believe that human memory is not like a camera at all, but more like a puzzle-piece by piece of clues in the mind are pieced together to form a story. In the process of piecing together, there will be loopholes or errors, and these loopholes or errors can be filled with new information to produce new stories. If new information fits into this loophole and can make the story more coherent and reasonable, then it can easily become part of the memory.
  So when the memory receives appropriate new information, it will continue to update automatically, and these new information are fake memories. In this way, it may be more appropriate to compare memory to an editable web page: we can find a web page at any time and add or delete information on it. Not only can we do this ourselves, others can also edit our memories.
  Going back to the memory of the young woman before, maybe 5 years ago, she just used a small stone to drive away a barking stray dog, but the psychologist input another girl, two police officers and other information. . These new information (fake memories) were added to the woman’s memory web page by psychologists, which happened to be so “reasonable”, so the false memories settled in the woman’s brain and took root and grew. The end result is that every time the brain retrieves this memory, only the latest version of the page is available-she found herself attacking another girl with a stone.
  Although the above false memory is just a small experiment by psychologists, it can be said to be harmless, but some examples are different. It can even be said that a false memory may endanger life…
  false memory and “murder”
  In the early morning of one day in 1996, Damon Sibodex was taken away by the police as a suspect. After 9 hours of interrogation, the 22-year-old young man from Louisiana, USA, admitted that he had raped and strangled his cousin. When he pleaded guilty, he had not slept for 35 hours.
  Faced with the interrogator, Siebodex felt pressured. The interrogator always believed Sibodex’s defense was a lie. Not only did he use a polygraph on him many times, he also kept telling Sibel the “true” version of the case. Dex listened. In the end, Siebodex “remembered” what had never happened, and admitted that he had never committed a murder. “I don’t know that I did it, but I did it”-Siebodex told the interrogator.
  Soon after, he was sentenced to death. He stays in a cramped cell every day, waiting for the day of execution. Fortunately, things turned around. In 2012, a DNA test proved his innocence, and the court acquitted him. Sebodex is the 300th innocent prisoner released because of evidence from a DNA test in the United States.
  In many cases of misjudgment, the initial conviction may be due to false memory. The interrogation room is a special place. In order to obtain the required statement, the interrogator will ask many questions like this: What did you see? Or did you see that car?
  If the interrogator uses the latter question, then the suspect will be in trouble. Unless he answers “There is no car, how can there be any car”, otherwise no matter if he answers “not seen” or “seen” at this time, that car The “non-existent car” will be smoothly implanted in the memory of the suspect and can be used to confuse the memory of the suspect’s past. Upset suspects are more likely to believe the implanted version of the event than their own original memories.
  In this way, fake memories are really dangerous. So, here comes the important question-how many false memories are in the brain?
  How many false memories are there?
  1%, 10%, or 50%? Unfortunately, no one knows. The only certainty is that if memory is compared to banknotes and the brain is compared to the market, then just like all kinds of fake money circulating in the market, all kinds of fake memories will be interspersed in the brain.
  Interestingly, researchers believe that the brain memories about our lives before the age of 3 are basically false, and almost all “experiences” are made up. But how are they constructed? Mom and Dad often tell us many stories, and then we will build a “memory building” on top of these stories.
  Many things in childhood are the same. Many people say that they still remember certain scenes of childhood, but the reality is that the hippocampus (the main control center of memory in the brain) at this age is not mature enough to store memories for a long time. However, we regard some of the information we learn from others as our own memory.
  In addition, we cannot judge whether a memory is real or fictitious, because they are all controlled by the same area of ​​the brain, and there are no tools that can be used to distinguish the true from the false. At this point, do you want to ask, isn’t it possible to scan the brain now? But the researchers said that even if the brain is scanned, the scans of real and false memories look the same.
