Ebbinghaus forgetting curve
German psychologist Ebbinghaus found that forgetting starts immediately after learning and the process is uneven.
Forgetting pattern:
- • After 20 min: 42% forgotten
- • After 1 hour: 56% forgotten
- • After 1 day: 74% forgotten
- • After 1 week: 77% forgotten
- • After 1 month: 79% forgotten
Reviewing at specific time points can greatly improve memory retention.
