The change in the forgetting curve is characterized by the year in which the forgetting curve was pr

This curve tells people that forgetting in learning is regular, and the process of forgetting is fast, first fast and then slow. If you look at the curve, you will find that after a day, if you don't review it quickly, you will only be able to leave 25% of the original knowledge. Over time, the rate of forgetting slows down, and so does the amount of forgetting.

Someone did an experiment in which two groups of students studied a text, and group A did not review it after studying, and the memory rate was 36% after one day, and only 13% after a week. Group B reviewed according to the Ebbinghaus memory rule, and the memory rate was 98% after one day and 86% after one week, and the memory rate of group B was significantly higher than that of group A.

This curve tells people that forgetting in learning is regular, and the process of forgetting is not balanced, not a fixed number of days to be lost, and a few more to the next day, but the speed of forgetting is very fast in the initial stage of memory, and then it gradually slows down, and after a long time, it is almost no longer forgotten, which is the law of the development of forgetting, namely"Fast first, then slow"principles. If you look at this forgetting curve, you will find that after a day, if you don't review it quickly, you will only be able to leave 25% of the original knowledge. Over time, the rate of forgetting slows down, and so does the amount of forgetting.

Someone did an experiment, two groups of students studied a text, group A did a review shortly after learning, group B did not review, after one day group A remained 98%, group B maintained 56%; After one week, Group A maintained 83% and Group B remained at 33%. The mean of forgetting was higher in group B than in group A.

The first few days all at once it fell sharply, and the longer the days passed, the more flat the line became.

Forgetting curve: describes the law by which the human brain forgets new things.

Forgetting curvesYesEbin Stove told HausPresented in 1885.

The forgetting curve, discovered by the German psychologist Ebbinghaus, describes the law of the human brain forgetting new things. The human brain is a step-by-step intuitive description of the forgetfulness of new things, and people can grasp the law of forgetting from the forgetting curve and use it, so as to improve their self-memory ability. This curve has had a significant impact on the study of human memory cognition.

The Law of Forgetting:

The process of forgetting is uneven, and its tendency is to be faster and then slower, first more and then less, showing a negative acceleration, and to a certain extent it is no longer forgotten. Specifically, after 20 minutes, 42% were forgotten and 58% were remembered; After 1 hour, 56% were forgotten and 44% were remembered; After 1 day, 74% were forgotten and 26% were remembered; 1 week later.

77% are forgotten and 23% are remembered.

After 1 month, 79% were forgotten and 21% were remembered.

The name of the normal person's forgetting curve is the Ebbinghaus memory forgetting curve, which is characterized by a rapid rate of forgetting at first, and gradually slowing down later.

German psychologist Ebbinghaus (Research found that forgetting begins immediately after learning, and the process of forgetting is not uniform. Forgetting is fast at first, and gradually slows down later. He thinks"Keeping and forgetting are functions of time", he uses meaningless syllables (syllables that are made up of a number of syllabic letters and can be read, but have no content meaning, that is, are not words) as memory material.

The amount of retention and forgetting is calculated using the saving method. Based on the results of his experiments, he drew a curve describing the process of forgetting, which is the famous Ebbinghaus memory forgetting curve.

Manifestations of Oblivion:

There are several different manifestations of forgetting: Retrograde amnesia is the forgetting of past events, and new memories can still be formed, but this is relatively rare. When the lesion occurs, it may cause amnesia.

1. Anterograde amnesia.

That is, the inability to recall events experienced in the period of time after the onset of the illness. The time of forgetting and the disease begin at the same time.

2. Retrograde amnesia.

That is, the inability to recall events at a certain stage before the onset of the disease. Forgetting may be complete or partial, but mostly only involves a shorter period of time.

3. Progressive amnesia.

It is mainly seen in Alzheimer's disease. The greater impact is not direct recognition and preservation, but re-recognition and recall, that is, in addition to forgetting, the patient is accompanied by increasing dementia and apathy. Some patients have both retrograde and anterograde amnesia, and the transition from one to the other can also be seen, as seen in patients with head trauma.

The German psychologist Ebbinghaus conducted a systematic study of hand-staring memory and forgetting. In order to quantitatively analyze the results and remove the interference of past experience, he used nonsensical syllables, which consist of three letters (consonant-vowel-consonant), as memory material. He plotted the experimental data as a curve called the Ebbinghaus forgetting curve.

Its ordinate represents the amount of holding. The curve shows a law of forgetting development: the forgetting process is uneven, the initial forgetting is very fast, then gradually slow, and at a considerable time, almost no longer forgetting, that is, the development of forgetting is "fast first and then slow".

Based on this curve, we find a relationship between the relative time spent learning a question and the time interval between timely revision: the shorter the time between timely review and the last learning time, the shorter the relative time spent.

The forgetting curve was proposed by the German psychologist Alan Bloom (ebbinghaus) in 1885. He found that when people learn a new task, memory weakens over time. This is the oblivion line.

It shows that if we don't repeat the lessons, people's memories of things will gradually weaken over time.

Answer: a

German psychologist Ebbinghaus found that forgetting begins immediately after learning, and the process of forgetting is not foolish and even. Forgetting is fast at first, and gradually slows down later.

Answer]: A For the process of forgetting the development, the German psychologist Ebbinghaus was the first to conduct systematic research. The results of his study are plotted as curves, i.e., the Ebbinghaus forgetting curve, which indicates that forgetting begins immediately after learning, and that the process of forgetting progresses quickly at first, and gradually slows down after the uproar; After a considerable amount of time, it is almost forgotten.

That is, first fast and then slow. Therefore, the answer is A.
