What Is the Function of Iconic Memory?

Forgetting is a special function in memory. Human sense organs receive a lot of information. And forgetting makes people only keep important and relevant information, which reduces the stress of brain space, which has a positive meaning.

[wàng jì]

Chinese name: forget
Foreign name: forget

Pinyin: wàng jì
Explanation: Don't remember the past

Whether an event will be forgotten depends on the number of events associated with it, the emotions and time it evokes, and the physical state. However, it is generally believed that forgetting is passive relative to memory. That is to say, people can choose to remember something, but they cannot choose to forget something. In order to avoid forgetting important information, people usually review it.

Forget the physiological mechanism

According to the theory proposed by the brain research to explain the physiological basis of memory, when a person is remembering, a new specific synaptic connection is established between neurons. When a person wants to remember many things, these single synaptic connections become "networks."

The advantage brought by the network is that when the information needs to be read, the entry point of the process does not have to be the information itself, but also other nodes on the network. Then follow the connection between the cut-in node and the node that needs the information (this process is called association), the brain can also get the required memory information and load it into "memory".

This also explains that the more connections a single event has with other events, the less likely it is to be forgotten. In contrast, isolated individual events are easily forgotten.

There are two types of forgetting: the first is the disappearance of synaptic connections in memory. The second is temporary inactivation of memory synapses. The result is the same for both, that is, the brain's attempt to read that information fails.

But the second kind of explanation can better explain why people can accept or memorize things that are impressed faster. This is why previews are promoted. The review is that the brain repeatedly reads certain information, on the one hand, reactivating those inactivated memory synapses, and on the other hand, it can establish more nodes to connect with this information, so that the next time it can read the information faster The purpose of the information.

Forget about time

The speed of forgetting is related to the time of memory. In this regard, there is a well-known "Ebbinghaus Forgetting Curve" theory. This is mentioned in the book "On Memory" published by German psychologist Ebbinghaus in 1885. It is thought that the speed of forgetting is the fastest after the memory, and then slowly slows down until the forgetting stops. But at this time, the memory content is less than 30% of the original. It is also because of this discovery that some people have proposed a "four review method" for learning.

Forget about emotion

Forgetting is selective. According to the so-called Peters principle, what people forget is related to emotional factors. One quickly forgets things that are indifferent. On the contrary, things that cause a strong emotional response are hard to forget. Things that cause positive emotions (pleasure) are retained for a long time, while things that cause negative emotions (unpleasantness) are not. The days of the past are therefore mostly good times, because this selectivity removes negative and general things while retaining positive content.

Different theories have basically the same consensus, that is, forgetting is an important function of information processing. Forgetting is the organization of memory content, making it systematic and structured. Through this process, important information is stored in a concise and easy-to-read manner. R. Dreistadt set out from this understanding to explain the phenomenon of "flash of light" in daily life.

There is a mental illness called post-traumatic stress disorder (PTSD. Also translated: post-traumatic stress disorder). Patients will constantly read previously unpleasant and even terrible memories. This mental illness is seen in American Vietnam veterans. It is thought to be caused by obstacles in the process of forgetting.

After falling in love, we always ask:

"How can I forget him? I want to forget him, but I just can't forget him."

If you can't forget him, don't forget it.

Why is it so painful to forget someone? Time will naturally make you forget him.

I ask you not to think of a pink gourd.

Excuse me, what do you think of?

You immediately think of a pink calabash baby.

The harder you try to forget, the more you cannot forget.

It is a matter of course that I still love him and cannot forget him. Don't feel ashamed.

Some people can't forget, but they deceive themselves and say:

"I have forgotten him."

However, as soon as someone mentioned him, she couldn't control herself.

One day you will forget him.

Real forgetting requires no effort.

One day, you took a bath out of the bathroom, turned the record player to listen to your favorite music, and you suddenly remembered that you once loved a person, ah, it turned out that you loved this person, it seemed to be far away You have no feeling at all. This is forgetting.

One day, when someone mentioned XX, you suddenly remembered that you once loved this person and don't remember it. This is forgetting.

If time can't make you forget those you shouldn't remember, what's the point of our lost years?

Forget the physical state

Unlike the aforementioned forgetfulness, there are various pathological forgetfulness in medicine, namely dementia. A famous example is Alzheimer's disease. The disease develops chronically and worsens with age. Forgetfulness caused by an accident or accident, such as shock or concussion, is called amnesia. There is also amnesia for a specific period of time in patients with rickets, which can be accompanied by identification disorders. For example, after a woman had a quarrel with her husband, she was suddenly neurotic and alleged that she did not know her husband at all. After talking with the doctor, she learned that she had forgotten the whole experience of dating and getting married.

Forget to overcome

Memory is the reflection of past experience in the human brain. It includes the three basic processes of memorizing, maintaining, reappearing and recalling. Its forms include image memory, conceptual memory, logical memory, emotional memory, and motor memory.

The enemy of memory is forgetting. Improving memory is actually trying to avoid and overcome forgetting. As long as you carry out conscious exercise in learning activities and master the rules and methods of memory, you can improve and improve memory. Here are ten ways to enhance memory.

1. Pay attention to concentration. As long as you focus on your mind and focus on your mind, eliminating distractions and external disturbances, the cerebral cortex will leave deep memory traces and will not be easily forgotten. If you lose your mind and work for two purposes, memory efficiency will be greatly reduced.

2. Strong interest. If you have no interest in learning materials and knowledge objects, even if you spend more time, it is difficult to remember.

3. Understand memory. Understanding is the foundation of memory. Only deeply understood knowledge can firmly remember it. Understanding memory is better than mechanical memory.

4. Over learning. That is, on the basis of memorizing the learning materials, memorize several times to reach the level of memorization and memorization. The optimal level of over-learning is 150%.

5. Review in time. The speed of forgetting is fast first and then slow. It is an effective means to strengthen the memory traces and prevent forgetting about the newly learned knowledge.

6. Always recall. When learning, keep trying to recall, so that memory errors can be corrected and omissions can be made up, making it difficult to memorize the learning content. In your spare time, often remembering the objects you remembered in the past can also avoid forgetting.

7. Combination of reading, thinking, watching and listening. It can use language functions and the functions of audiovisual organs at the same time to strengthen memory and improve memory efficiency, which is much better than single silent reading.

8. Use multiple memory methods. According to the situation, the flexible use of classification memory, characteristic memory, homophonic memory, arguing memory, associative memory, fun memory, graphic memory, shortening memory and compiling outline, making notes, cards and other memory methods can enhance memory.

9. Master the best memory time. In general, the best memory time is 9 to 11 am, 3 to 4 pm, and 7 to 10 pm. Using the above-mentioned learning materials that are difficult to remember, the effect is better.

10. Scientific brain. On the basis of ensuring nutrition, active rest, physical exercise and other brain maintenance, using the brain scientifically to prevent excessive fatigue and maintain a positive and optimistic mood can greatly improve the working efficiency of the brain. This is the key to improving memory.

Forget the training method

Five ways to train concentration in the field:

1. Take a tennis ball, put it in front of you, stare at it, and focus your attention completely on it. Keep this tennis ball in your head and try to increase the training time gradually. (External visual)

2. Close your eyes, use your imagination to imagine the ball, and focus on it. Try to gradually increase the training time. (Internal visual)

3. Take a metronome, turn it on, focus your attention on the rhythm, and fill your mind with this rhythm. If something else appears in your brain, let it float like a cloud. (External auditory)

4, choose a sentence or a word, it is best to be more positive, and then repeat to yourself. Repeated in your mind like a recording. Try to gradually increase the training time. (Internal auditory)

5. Watch your breath. Feel the air in and out of your lungs and let your breath calm you. Every time you inhale, it seems like you have increased your ability to concentrate, and every time you exhale, it seems like you have exhaled other thoughts. Inhale with your nose and exhale with your mouth. (External auditory and internal kinesthetic)

Five ways to train concentration on the field:

1. Focus on the ball in flight. Fill your brain with this sporty ball and don't let anything else in. Stay focused and focus on the ball. (External visual)

2. Focus your attention on the bounce of the ball or the sound of your and your opponent's hits, and keep up with this rhythm. (External auditory)

3. Inhale when your opponent hits the ball and exhale when you hit the ball. Focus on your breathing and let it calm you down. (Internal kinesthetic and external auditory)

4. During the matchup, before hitting the ball, say "offense", "come up" or something similar to yourself, and let this sentence fill your mind. (Internal auditory)

5, Between points and points, let a static or moving imaginary image appear in your mind, such as a special tactical arrangement, or your own image full of fighting spirit. You can also imagine the words "sedation", "COME ON" and so on appearing in your mind. These words must be short to make it easier to focus on it completely.

12 foods that enhance memory

Hundreds of millions of nerve cells in the human brain are constantly carrying out heavy activities. Scientific research has confirmed that diet is not only a necessity for maintaining life, but also plays a very important role in the normal operation of the brain. Some foods help to develop people's intelligence, make people's thinking more agile, more concentrated, and can even stimulate people's creativity and imagination.

Studies by nutritional health experts have found that some foods that help to strengthen the brain and intelligence are not expensive and hard to find, but are just cheap and ordinary things that can be found in everyday life. The following foods are very good for the brain, and mental workers and students may wish to choose food frequently.

1. Milk. Milk is a near-perfect nutrition. It is rich in protein, calcium, and amino acids necessary for the brain. Calcium in milk is most easily absorbed by humans and is an indispensable important substance for brain metabolism. In addition, it also contains vitamin B1 and other elements that are very good for nerve cells. If you use insomnia and insomnia, a cup of hot milk before bed will help you fall asleep.

2. Eggs. Brain activity and memory are closely related to the content of acetylcholine in the brain. Experiments have shown that the beauty of eating chicken is that when the rich lecithin contained in egg yolk is broken down by enzymes, it can produce rich acetylcholine, which will quickly reach the brain tissue after entering the blood, which can enhance memory. Foreign studies have confirmed that eating 1 or 2 eggs a day can supply sufficient choline to the body, which is great for protecting the brain and improving memory.

3. Fish. They can provide high-quality protein and calcium to the brain. Most of the fatty acids contained in freshwater fish are unsaturated fatty acids, which will not cause vascular sclerosis and are not harmful to cerebral arteries. On the contrary, they can also protect cerebral blood vessels and promote brain cell activity .

4. MSG. The main component of MSG is sodium glutamate, which can be converted into glutamic acid by the action of gastric acid. Glutamate is the only amino acid that participates in human brain metabolism and can promote intellectual development and maintain and improve brain function. Consuming MSG often helps to improve mental retardation and memory impairment. Because MSG increases acetylcholine in the brain, it also has a certain effect on neurasthenia.

5. Peanuts. Peanut is rich in lecithin and brain phospholipid, which is an important substance required by the nervous system, which can delay the decline of brain function, inhibit platelet aggregation, and prevent cerebral thrombosis. Experiments have confirmed that regular consumption of peanuts can improve blood circulation, enhance memory, and delay aging, which is a veritable "longevity fruit".

6. Xiaomi. Millet contains vitamins B1 and B2 1.5 times and 1 times higher than rice, respectively, and its protein contains more tryptophan and methionine. Clinical observations have found that eating millet has the effect of preventing aging. If you usually eat millet porridge and millet rice, it will be good for your brain?

7. Corn. Corn embryo is rich in a variety of unsaturated fatty acids such as linoleic acid, which can protect cerebral blood vessels and lower blood lipids. In particular, corn has a high water content and glutamic acid, which can help promote brain cell metabolism. Eating corn, especially fresh corn, has a brain-building effect.

8. Daylily. It is often said that daylily is "forget-me-not", which can "relieve depression". Note: Daylily should not be eaten raw or fried alone to avoid poisoning. Dry and cooked food is better.

9. Chili. Capsicum has the highest vitamin C content in various vegetables, and is also rich in carotene and vitamins. Capsaicin in pepper can stimulate taste, increase appetite, and promote blood circulation in the brain. Some people find that the "spicy" taste of pepper is still a hormone that stimulates the body to pursue career success, making people energetic and thinking. Peppers work better when eaten raw.

10. Spinach. Although spinach is cheap and inconspicuous, it is a brain healthy vegetable. Because spinach is rich in vitamins A, C, B1 and B2, it is one of the "best suppliers" of brain cell metabolism. In addition, it also contains a large amount of chlorophyll, which also has a brain health effect.

11. Oranges. Oranges contain a large amount of vitamins A, B1, and C, which are typical alkaline foods, which can eliminate the damage caused by a lot of acidic foods to the nervous system. Eating oranges in moderation during an exam can be energetic. In addition, lemon, citrus, grapefruit, etc. also have similar effects and can replace oranges.

12. Pineapple. Pineapple contains a lot of vitamin C and trace element manganese, and it has less calories. It is often eaten to refresh and refresh. Some people call it a fruit that can improve people's memory. Pineapple is often the favorite fruit of some musicians, singers and actors, because they have to recite a lot of sheet music, lyrics and lines.
