Why is the brain going wrong?

  When I walked into the room, I couldn’t remember what I was going to do; I saw a face from the doorknob smiling at you; I yelled the other classmate’s mother as “Mom”; when I walked to the ATM, how did the password go? No, the more eager, the more mistakes… These stupid things or mistakes after distraction, presumably you will not be strange in life? There is nothing in the end. How can we have such a low-level mistake in such a well-developed brain?
  These “low-level mistakes” are not low-level explanations and involve some advanced neurobiology knowledge. If you haven’t lost your mind at the moment, listen to me to explain.
  Why did I forget to do what I walked into the room?
  This frustrating thing is so common that it has its own name, called the “doorway effect.”
  Why should we emphasize the “doorway”? Because this “doorway” seems to be the key. Scientists have experimented and let people enter a room from one room. In the previous room, even on the way to go, they still remember the good things. When he crossed the door of the second room, he Suddenly I can’t remember it, as if this “doorway” really has the magic of intercepting memories.
  So what happened in the brain?
  Scientists now explain this: When we are active in the world, our brains interact with the environment by constructing a temporary “event model.” For example, in the living room of the hotel, we can’t scream loudly, we can’t dress up, and in our own bedroom, we can just pick it up. Corresponding to the living room environment, we have an “event model” about the living room in our brains, which teaches us how to behave in the living room environment; in the bedroom, we have a bedroom “event model” that teaches us to do this.
  But every time we can only be in one place, the brain is a smart guy who knows that it is not necessary and efficient to have multiple event models work together. It allows our memory to focus on the current environment, the things at hand.
  The doorway of another room happens to be the switching point for two different environments. When you step in, trigger the brain to replace another “event model” with another “event model.” This change makes it easier for us to forget what happened in the former environment. For example, if you wrote in the previous room to take the chair in the next room, when you stepped into the door of the next room, you suddenly couldn’t remember it. Let you stand there and beheaded, not knowing what to do.
  This experience can be triggered not only by the door, from the countryside into the town, from the highway to the remote streets, or from the downstairs to the upstairs.
  Why not stop thinking about a word and make it meaningless?
  Coffee, coffee, coffee… Constantly chanting a word will make you suddenly feel strange to it, not only can’t spell it, even the meaning doesn’t understand. Not only chanting, but also watching for too long. For example, a commonly used word, if you stare too long, it will suddenly become strange, as if it is weird. This phenomenon is called “semantic saturation” by psychologists.
  This phenomenon has been well studied and is believed to be the result of neuronal fatigue in the brain. When a neuron discharges, it consumes energy. It usually discharges immediately for the second time, but if it is discharged endlessly, it will eventually get tired and must rest for a while before it can be discharged again. When we read a word over and over again, we are exhausted by the neurons that are responsible for dealing with all aspects of the process—its form, meaning, and evoked associations. Therefore, this word can no longer show meaning in our consciousness.
  And the words are not the same as words. Words that are rich in meaning or more emotional, such as “killing”, may need to be repeated for a longer period of time before they become strangers. This is because every time you read the word, your brain will think of different things (such as this time associated with the Nanjing Massacre, the next association with the Nazi concentration camp); these different associations prolong the brain’s active time, fatigue is delayed It is. And those words that are not rich in meaning, simple and clear, such as “coffee”, may only need to be repeated several times to become strangers.
  How do you suddenly forget your password?
  They are a few simple numbers that you have used for years… Then one day, in front of the ATM, you suddenly got the wrong password. Worse, the harder you work, the more you can’t remember these numbers. How can such a familiar thing suddenly disappear?
  Our memory is thought to be stored in the gap between neurons – the synapse, through which electrical impulses are transmitted from one neuron to another. Each discharge enhances the connection between the relevant neurons, making any activity in the previous neuron more likely to stimulate the latter neuron. For example, a flower looks like it is stored in a neuronal network. The name of the flower is stored in the B-neuron network. When we consider its appearance and name at the same time, the link between the A and B neural networks will be activated and strengthened. . When we recall the appearance of flowers in the future, its name is more likely to be remembered at the same time. This is the basis for our long-term storage of information (including passwords).
  In addition to serious illness, there are two main factors that cause us to lose memory occasionally. The first factor is that if not often activated by recall, the connections between neurons will diminish over time. The reason why you can’t remember this password may be that you haven’t used it for a while.
  Another reason is interference. When we reawaken a memory, the memory becomes malleable and easy to change. In the example of forgetting your password, you may have used these numbers in other ways. For example, you recently messed up these numbers and created a registration password for a website – so in your mind, The original memory was replaced. Or you recently received a password for a new card, so you confuse the two passwords.
  Your mentality may also be the culprit: As we all know, mental stress can bring a lot of chemicals that destroy memory. For example, mental stress can lead to elevated cortisol in the blood, while cortisol destroys synapses. However, numbers that you use often like passwords are generally not completely remembered, so please take a break and try again later.
  If you still don’t remember after the break, it’s best to try to use visual images to help you remember—for example, recall the lines that your fingers draw on the keyboard when entering the password. Studies have shown that it’s easier to think of the things we want to remember and the images.
  Why do some people see faces on Mars?
  Some people claim to see a face on Mars; in history, many people claim to see Jesus’ faces from walls and stones… Seeing faces from inanimate objects is well known to psychologists. The phenomenon is called “the fantasy illusion.” Even monkeys have this experience. But why?
  Our brains tend to like to see faces from a very young age. The fetus can recognize the shape of the face from the uterus – the scan shows that when many spots of the laser are used to simultaneously illuminate the skin of the mother’s abdomen, if they are arranged in a pattern of faces, it is easier to attract the fetus to turn around to pay attention. And the random pattern does not have this effect.
  Studies have shown that when an illusion of illusion occurs, the area of ​​the brain involved in the processing of the face is activated. This means that even if there is no real face outside, the brain is going to link what you see to the face.
  Why are our brains so partial to people?
  Evolutionarily, it makes sense for the brain to be highly alert to faces. Because people are social animals, there are far more opportunities to deal with their own kind than with other animals. We need to observe other people’s motives by observing people’s facial activities – are they friends or friends? In order to respond.
  As a result, our brains occasionally overdo it, and in the face of no one will also inexplicably see a face, let us stunned. But there is always no harm in being alert. Imagine if you couldn’t find the face of an enemy hidden in the forest in time, the consequences would be unimaginable.
  What caused our mistakes?
  There are a lot of jokes about the wording on the Internet, for the time being.
  ”One day, I went to my neighbor’s house to borrow something. Their family was eating melon. When he loaned me something, I shook my head and said, ‘I don’t eat…'”
  ”The year-end meeting of the unit, a leader took the stage to congratulate: ‘I wish everyone happy!’ Everyone is stunned.”
  ”Going to the classmate, his mother opened the door, I was nervous and shouted ‘Mom.'”
  According to Freud’s psychoanalysis, any oral error is not a simple small mistake, but a hidden motivation or real thought that reveals the innermost feelings of the person. Explaining the above first mistake in this way seems to be plausible. The “I” mistakes did reveal the true thought that “I” thought that the neighbor would take me to him. But the other two mistakes, what do you think the talking person has a hidden motive?
  Neurobiologists are much more tolerant in explaining their spoken errors. They believe that when we talk, the brain evokes many neural network cooperation, such as a memory network that evokes all the words that may be used, and a network that handles meaning. The cooperation between neural networks helps us to form sounds. When doing so many tasks at the same time, the brain will inevitably make mistakes occasionally, for example, can not suppress the alternative choice of a word (such as the second case of slip, “happy” instead of “health”), or activate one instead of another The pronunciation of a word. Therefore, the spoof is sometimes just a conflict between several different words in the choice.
