Spaced repetition

Definition

Spaced Repetition is a way of distributing reviews over time, often explained alongside Ebbinghaus’s forgetting curve. A sequence such as one, three, seven or twenty-one days is only an example. There is no universal schedule or guarantee that reviewing at the edge of forgetting is always optimal.

What the science does and does not say

Ebbinghaus’s early memory experiments helped describe forgetting over time. They do not establish that everyone loses 70% of all information within a day. Spacing and retrieval practice can be useful learning methods; no single schedule is best for every learner and subject.

Applications

• Language learning: vocabulary and grammar
• Exam preparation
• Professional knowledge, including medicine and law
• Habit reminders can be scheduled too, but memory-study findings do not prove automatic habit formation

Learning routines in Sinqly

Record a review habit and choose suitable intervals using your learning material or a dedicated revision tool. Adjust reminders yourself. Automatic scheduling based on habit stability or prevention of notification fatigue is not promised here.
