With really only seven seconds of memory? What is a seven second memory

Seven-second memory means that the memory of the fish only lasts for seven seconds, and once the seven seconds have passed, everything is new, so they never feel alone. On the Internet, there is a passage that is widely circulated: "A long time ago, someone told me:

The fish only remembers for 7 seconds, and after 7 seconds it will not remember what was before, and everything will be a new beginning. So, in that little fish tank, it will never get bored. ”

According to Ashleyward of the University of Sydney, this statement comes from an advertisement. Ward argues that early zoologists used overly complicated methods when testing the memory abilities of fish. These tasks, which are suitable for testing human intelligence, are obviously too difficult for fish, so the fish experimented with have a rather bad record.

In conclusion, all studies on fish memory show that fish memory is much more than 7 seconds. The saying that "the fish has a closed memory of only 7 seconds and never gets bored" is just a legend, despite its beauty.

About memory: Memory is the human brain's recognition, retention, reproduction or re-recognition of experienced things, and it is the basis for high-level mental activities such as thinking and imagining. Human memory is related to changes in the structure of the brain's hippocampus, the chemistry inside the brain.

The study of memory falls under the umbrella of psychology or brain science. The study of memory continues in modern humans, despite the fact that science and technology have come a long way today. The use of those methods and techniques that can effectively improve memory after practice can make them better serve human work, life and study.

It is wrong for a fish to remember only seven seconds.

In fact, if the "fish memory has 7 seconds" is taken as a scientific conclusion, many questions will arise. Can memory be accurate to the second? If the average memory of a fish is 7 seconds, then don't some of the dumber fish have only a memory of seconds?

When these "stupid" fish take a bite of food, will they instantly forget what they are holding in their mouths?

Fortunately, fishes have a rather unique evolutionary status as the earliest species of vertebrates, so there is a lot of scientific research on fish memory. Although the types of fish used as experimental materials are different, and the methods and specific purposes of the experiments are different, almost all studies on fish memory show that fish memory is much longer than 7 seconds.

For example: Paradise Fish – also has a strong memory. When this fish encounters a strange goldfish in the pool, it will swim around curiously, looking at the new strange neighbor until it loses interest.

If the Paradise Fish and the Goldfish meet in the tank for the second time, they will quickly discover that each other is an old acquaintance and lose interest in exploring. Experiments have found that such memory can be maintained for at least 3 months.

Zebrafish – is also a fairly intelligent animal that can accomplish a wide variety of tasks. In 2002, several researchers at the University of Toledo in Ohio, USA, tested zebrafish for memory. During training, they would give the zebrafish a red light as a signal before feeding, and 10 days after the training was stopped, the zebrafish still remembered that the red light was a sign indicating that it was time to eat [5].

In the lab, zebrafish can also quickly learn how to walk the maze [6], search for food based on sound signals [5], memorize the shape of predators, and dodge electric shocks according to prompts.

"Seven seconds of memory" is a well-known saying, but it's really just a misconception. In fact, human short-term memory is far more than seven seconds long.

Short-term memory refers to our ability to store and process information temporarily, usually between a few seconds and a few minutes. The so-called "seven-second memory" stems from a psychological study that has been overturned and claims that humans have a short-term memory capacity of 7 items (i.e., people can only remember about 7 separate units of information at the same time). However, follow-up studies have shown that this number is not accurate and that our short-term memory capacity can vary depending on a variety of factors, such as the complexity of the information, the individual's cognitive ability, etc.

In fact, human short-term memory capacity can be improved by making chains good with memory techniques and training. For example, methods such as chunking (dividing information into larger units), repetitive memory, and associative memory can improve the effectiveness and persistence of memory.

In short, don't be bothered by the misconception of "seven-second memory". Humans have a short-term memory capacity of much more than seven seconds and can be improved in different ways.

Legend has it that the fish only remembers for 7 seconds, and after 7 seconds it doesn't remember.

Things have happened in the past, so in a small fish tank.

It doesn't get bored either, because after 7 seconds of key shifts.

Every inch of the place that swims through.

It's a new world again.

It's in those 7 seconds.

Constant reincarnation is not for forgetting, but for remembering.

When there is a dream, the happiness is incomparable, the dream is born from the heart, and the green grass is spring.

Spread diligently. Perhaps, the wind and snow will never be fruitless, but after all, it is a story of wind and snow, and happiness is enough ......”

This is Xu Zhimo's poem, titled "Memories of Fish".

In this way, accidentally, a fish and a carp hit a child, and jumped into Xu Zhimo's poem ......

Later, with curiosity, I checked the relevant information and learned that the statement that "fish only have a seven-second memory" is unscientific.

However, with only seven seconds of memory, it is truly amazing. I began to reverie: I'm not a fish, but I'm ......

If I only had seven seconds of memory, I would remember the best things in life. Forget about everything unpleasant, remember the light, the warmth, remember the care, the kindness ......I will paint my life with warm and bright colors.

If I only have seven seconds of memory, I will forget about other people's hurts, remember their most beautiful smiling faces, and remember the happiest moments with them.

If there were only seven seconds of Bu Xun's memory, I would forget the ups and downs and tribulations I experienced, I would forget the darkness and pain of the long night, I would forget the coldness in the rainstorm, and the helplessness in the snowy field. I will remember the new green in early spring, the glimmer of dawn, the rising sun in the morning, and the magnificent ...... at sunset

If I only have seven seconds of memory, I will continue to experience it, forget the pain, forget the unhappiness, forget the past. Then with a new me, I will embrace this beautiful world, embrace the wonderful every day, embrace the steaming life, and embrace the future worth looking forward to.

If you say, everything in the world is a reunion after a long absence. It is nothing more than a deep and shallow relationship, and a gathering and scattering of fate, I am willing to cultivate a good relationship and bear a good fruit.

If I only have seven seconds of memory, I would like to leave in this world the elegant and fragrant words that record what I think, think, and feel, so that they will always bloom beautifully, exude warmth, and never wither ......

If the fish really only have seven seconds to recall. —Epigraph.

We often hear that fish only have seven seconds to dig into their memories, and I feel very sad for some reason. Some people say that in this way they will not remember the painful and unpleasant things in life, and even if they do, they will not even have the right to remember happiness.

It suddenly occurred to me that if someone in the world fell in love with a fish?

It was a brightly colored goldfish with the smoothest scales and the brightest sheen in the world. A little boy met him by the lake and made a promise for the fish. Every day after that, he would come to the lake to visit it.

Hello, my name is Buren, what's your name? The little boy asked solemnly. Yu'er Juehuihe suddenly said, My name is Sha Li, and I am glad to meet you.

Bren was happy to talk to it and kept talking to it. But the next second the fish finished speaking, it forgot everything. Then the fish asked, "Who are you?"

The boy was stunned for a moment and said, "My name is Buren, and you know you Shari." The little boy engraved his name in his heart, but the fish forgot his name over and over again.

So the first thing the little boy said when he saw the fish was, "Shari, I'm Bren, I know you forgot, but it's okay, even if you can't remember it, my name will still be repeated in your ear ten thousand times, I promise." This is repeated many times a day.

It wasn't until the fish was on the verge of death that it finally struggled to remember its name. In the end, the fish died, and its life, as well as the last seven seconds of memory before death, belonged to the little boy, even if he couldn't remember what you looked like, I think ......I'll remember your name too.

I believe that the fish in the next life will definitely turn into the little boy's favorite girl, and once again, fall in love with it at first sight.

The memory of the fish is only seven seconds, and the next sentence is my memory with you。This is a very contagious love phrase, they are repeating the same insistence on an infinite loop, maybe a nectar can solve this crisis, and people can remember for a long, long time, they can also think for a long, long time, some people they each went to their own rivers and lakes, and never forget, leaving regrets in vain. And some people choose to stay where they are, although the days are very hard, but they can't avoid going to the rivers and lakes together to have gains and losses.

The fish's memory has only a seven-second provenanceLegend has it that the memory of the fish is only seven seconds, and after seven seconds, it does not remember the past, so in the small fish tank, it does not feel bored, because after seven seconds, every inch of the place that swims through has become a new world, and it does not tease the reincarnation in these seven seconds, not to forget but to remember. These are excerpts from Xu Zhimo's long narrative poem "Ashima".

In just a few sentences, it outlines a kind of Xu's beauty. In order to live happily in this chaotic world, I must practice the memory of a fish, and for unimportant information, my memory is only seven seconds. The past is a passing moment, reluctant to delete it, leaving behind troubles and entanglements.

I want to erase you from my memory, but I always can't help but think of every moment of your dreams, every minute and every second when you wake up.

In the morning, I listened to Mr. Qin Jie's writing class, and he said that change is the best motivation for writing, and it is more important to enter the brain than what is at the entrance. If I want to write a good article, I have to type first, and start with change. The teacher mentioned Stephen King's "Writing This Thing", and reading a book is the best input, so I became interested in this book.

When I searched on the Internet, many books about writing popped up, and after browsing the content introduction, I bought "Writing" and "Breathing Writing Reflects the True Voice of the Heart" and "My Reading and Writing". I like to buy books bad habits have not changed, once there is a recommendation I can't help but want to buy a look, although the speed of buying books is faster than my reading speed, the family is almost unable to find the place book of the reed liquid prescription, but I think reading will always be beneficial, there are books better than no books, as long as you have time, you can take it at any time to see, compared to e-books I prefer paper books with ink fragrance, so, has not stopped buying books. Fortunately, my husband spoiled me, and I bought and bought.

He probably thinks that a wife who likes to buy books is more beautiful and cute than someone else's wife who likes to go shopping and buy clothes :).

As I get older, I have forgotten many of the books I have read, although now I will forget while reading, but this does not affect my enjoyment of the various emotional experiences in the process of reading, and the various waves and thoughts in my heart when reading are real, rich and profound. I may not remember any specific takeaways, but I know for sure that I must have been touched when I read it. That's why I can't stop buying and reading books.

From this, I have a slight feeling: life is made up of countless seconds and seconds, and each second is meaningful and truly happy. The sky leaves no traces, but the bird has flown over The bird does not need the sky to leave traces proving that it has flown because it knows that it has flown over.

Legend has it that fish only have seven seconds of memory, and for fish, there is a very beautiful story, that is, seven seconds of love. The memory of the fish is very short, but the two fish, confirmed the eyes, met the right person, just because of the nostalgia for each other's eyes, from then on open the door of each other's closed hearts, each time seven seconds later, a vigorous love, will disappear. These seven seconds of love make the fish happy, they have experienced it, and in the end they forget it, and it will not be painful.

But a couple of infatuated men and women have loved, and after breaking up, they will leave pain and can't let go. Therefore, the love of fish makes everyone yearn for it.

Recently, there is a very popular sentence on the Internet, "What do you want to do most when you grow up?" - I want to be a child again." When you grow up and enter society, you will feel the pressure of the environment, and you will miss the feeling of childhood.

Because at that time, no matter how big the event was, as long as you sleeped, you woke up the next day and forgot everything.

Some people blame their own suffering on the brain's memory function, "If today's things are clear today", don't carry today's memories to tomorrow, then tomorrow will be a new day.

I am willing to have only one second of memory to remember the good of my family, friends, colleagues, students and all the people I have related to, to accompany the source to forget the unhappiness and troubles they have given me, to remember the good, to forget the evil, and to be as happy as a fish every day.
