The memory of a fish is only seven seconds, what is the reason for affecting the memory of a fish?

The fish has more than seven seconds of memory.

The memory of the fish is only seven seconds, this is a topic on the Internet, most people think it is reliable, about the introduction of the fish, they all say that the memory of the fish is very short, that is, about seven or eight seconds, always remember only 7 seconds of what happened, it looks carefree, no matter where it is, it is quiet and peaceful. But scientists have questions about the memory of fish that is only seven seconds, is the memory of fish so poor? It can also be accurately memorized for just a few seconds.

Fish are not stupid, and their memory is not so short, of course, through very methodological observations, it is surprising to find that some fish are very intelligent, similar to humans, not to mention that fish only have seven seconds. <>

How long is the memory of the fish, in the 60s of the century, scholars are very curious, pay attention to this question, conduct memory research, on the goldfish, when doing the goldfish memory experiment, the goldfish receives an electric shock, the body suffers an impact, 20 seconds to release the electric shock again, the goldfish will have a frightened look, will quickly dodge, which shows that the fish not only has seven seconds of memory, and then grow the time, and even a month later use the electric shock, this goldfish still has a deep impression, after finding, will dodge. <>

It can be seen that the fish does not only have a seven-second memory, but has a long-term memory, in nature, there is a kind of fish called zebrafish, this kind of fish belongs to the fish is more intelligent, can live in nature, ** after training, can also complete various tasks, just like dolphins. Scholars are also studying zebrafish, after training, the fish quickly familiarize themselves with the training signals, put the zebrafish in the maze, through the corresponding signals, out of the maze to catch food, the memory analysis, found that the zebrafish and human memory are similar, to see that the fish is not stupid, the memory is not bad, there are secrets that humans have not solved. <

Not that all fish are smart, scholars explain that there are many small fish, whose memory is not as strong as that of zebrafish, who live at the bottom of society, face life pressure or predators, and need to pay attention to their own safety.

Different types of fish have different memory skills, but not only 7 seconds, but also have the ability to learn, and this ability plays an important role in fish avoidance, feeding and reproduction. The learning behaviors of fish include imprinting, habituation, conditioning, etc., which are based on memory. The most typical imprinting behavior in fish is the reproductive migration of salmon.

This is because fish are simple creatures with a small and simple brain and a very short memory! As creatures evolve, the higher the level of the organism, the longer the memory time and the stronger the memory.

The brain tissue responsible for memory is underdeveloped and only accounts for a small part of the fish's brain, but the memory of only seven seconds is a rumor, and it can only be said that the memory time of the fish is not long.

Fish only have seven seconds of memory?

The memory of the fish is only 7 seconds, which is not based on scientific evidence, but a popular phrase on the Internet, which means that the memory of the fish is only 7 seconds, and it will be forgotten after 7 seconds, and it will not remember what happened before, so it will not be boring in a small fish tank, reflecting loneliness and sadness, but after the research of scientists, it has been found that the memory of the fish is more than 7 seconds.

The fish memory is only 7 seconds for the reason.

The reason why it is said that the memory of a fish is only 7 seconds is because of the popular saying on the Internet: the memory of a fish is only 7 seconds, and after 7 seconds, it will not remember what was before, and everything will change back to a new beginning, so in that small fish tank, it will never be boring.

But in fact, the memory of the fish is more than 7 seconds, in 1965 researchers at the University of Michigan in the United States used bright light and electric shock to test the memory of the fish, and the fish after 20 seconds can still remember the bright light, so it shows that the memory of the fish is far longer than 7 seconds.

Catfish is a more common fish, in the process of breeding, the staff will knock on the plank, make a vibrating sound, so that the catfish gather together to eat, which will form a memory in the catfish's head, after an interval of three to four months, the catfish will swim over, which indicates that the memory of the fish is more than three to four months.

But in fact, the memory of fish is more than 7 seconds, in 1965 researchers from Michigan or Tan University in the United States used bright light and electric shock to test the memory of fish, and after 20 seconds, the fish can still remember bright light, so it shows that the memory of fish is far longer than 7 seconds.

Fishes, as an early species of vertebrates, have a rather unique evolutionary position, 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 also different, almost all studies on the memory of fish in Mingdong land show that the memory of fish is much more than 7 seconds.

Back in the 60s, when chemistry began to intervene in neurobiology, there were already people studying the memory ability of goldfish. In 1965, researchers at the University of Michigan in the United States conducted an experiment with goldfish. They put the goldfish in a very long tank, then shoot a bright light at one end of the tank, and after 20 seconds, release an electric shock at the end of the tank that shoots the bright light.

Soon, the goldfish developed a memory of the electric shock, and when they saw the light, they would quickly swim to the other side of the tank to avoid the electric shock before the electric shock was released. The scientists who designed the experiment found that with proper training, the goldfish could memorize the tricks of dodging electric shocks for up to a month.

Summary. This statement is actually a common rumor and is not accurate. Different types of fish species may have different memory abilities, but many can remember certain things for days, weeks, or even months.

For example, research shows that researchers at Nara University taught tuna to complete a task of chasing a ball in a swimming pool and then releasing them back into the ocean. A few days later, the tuna were trained again at another location to continue the same task, and as a result, they showed memory of the task and completed it faster. This suggests that tuna can remember at least some things for up to a few days.

Therefore, we cannot say that all fish have only 7 seconds of memory. Fish memory ability and time can vary from species to species, and it can also be affected by many other factors such as environment, food, and hormone levels in the body.

You've done a great job! Can you elaborate on that?

Everyone knows that the memory of a fish is only seven seconds, and no matter what happens, the fish will only remember a short seven seconds, and after seven seconds it will forget everything. Many people envy that fish have such a function, there are many things in life that everyone does not want to remember, if you have the memory of fish, then people will suffer a lot less. Is it true that fish only have a memory of 7 seconds?

Are all fish the same?

How long does the fish have a memory

Through the research of scientists, the memory of different fish is also different, but their memory is indeed a little short, but it is not only as short as seven seconds. Scientists in the United States once experimented with goldfish, they put goldfish in a fish tank, and used light and electric shocks to test the fish's memory of electric shocks.

When the fish have a memory of the electric shock, they will start to dodge the electric shock as soon as they see the beam, and after experimentation, the goldfish are able to remember the damage of the electric shock and avoid the electric shock for a month. Therefore, if the memory of the goldfish is trained, it can remember one thing for a longer time, so the memory of the fish can be increased.

In addition, there are other fish that should be able to remember one thing for a long time, such as the paradise fish, this fish will remember this fish after knowing a fish, and within three months, if they meet this fish, they will quickly get to know them and get along.

So not all fish memorize seven seconds, it takes time for them to recognize things, and the time for memorization will also increase. For most fish, the memory is indeed very short, they have too many fish in the water, not all of them can remember, they just have a deep impact on the harmful creatures.
