The usual process of memory is that the input information becomes short-term memory after learning in the process of people's attention, and becomes long-term memory after further strengthening. Long-term memory can be maintained for a long time or a short time. If you don't review in time, these things that have been remembered will be forgotten, but after timely review, long-term memory will continue to be maintained.
1 and 20 minutes later, 42% was forgotten and 58% was remembered.
2. 1 hour later, 56% was forgotten and 44% was remembered.
3. 1 day later, 74% was forgotten and 26% was remembered.
4. 1 week later, 77% was forgotten and 23% was remembered.
5. After1month, 79% was forgotten and 2 1% was remembered.
Extended data:
Ebbinghaus forgetting curve, in which the vertical axis represents the amount of knowledge remembered in learning, the horizontal axis represents time (days), and the curve represents the law of memory change. This curve tells people that forgetting in learning is regular, and the process of forgetting is unbalanced, which is similar to losing a few in a fixed day, but in reality, everyone's forgetting speed is very different because everyone has different understanding of information.
However, other scientists have found that age does not affect the speed of forgetting. Although with the growth of age, people's memory ability will generally decline, which means that the information that the elderly can remember will be relatively reduced. However, once the information is remembered, the elderly will not forget it faster than the young.
