Forgetting curve
The forgetting curve hypothesizes decrease in memory retention over time. This curve shows how information is getting lost over time, when no attempts were made to save it.
Experiment
The experiment conducted by Ebbingauz included a method of memorizing meaningless syllables which included two consonants and a vowel between them, not causing any semantic associations, that shows us that people were taught absolutely new information.
During the experiments, it was found that after the first unmistakable repetition of a series of such syllables, forgetting occurs very quickly at first: up to 60% of the information received is forgotten within the first hour, 10 hours after memorizing 35% of the studied one remains in memory. After 6 days, about 20% of the total number of originally learned syllables remain in memory. The same amount remains in memory after a month.
Conclusion
Conclusions based on this curve shows us that for effective memorization it is necessary to repeat the memorized material.
To memorize well, you need to use the phenomenon of rational repetition:
If you have two days:
1) The first repetition - immediately after reading;
2) The second repetition - 20 minutes after the first repetition;
3) The third repetition - 8 hours after the second;
4) The fourth repetition - 24 hours after the third.
If you need to remember for a very long time:
1) The first repetition - immediately after reading;
2) The second repetition - 20-30 minutes after the first repetition;
3) The third repetition - 1 day after the second;
4) The fourth repetition - 2-3 weeks after the third;
5) The fifth repetition is 2-3 months after the fourth repetition.
