Spaced Repetition: The Algorithm That Beats Forgetting Spaced repetition represents a systematic scheduling method for reviewing learned material at progressively increasing intervals that are optimally timed to counteract the natural forgetting curve, producing dramatically superior long-term retention compared to traditional massed practice or uniform review schedules that ignore the dynamics of memory decay and consolidation. The technique leverages fundamental findings from memory research showing that each successful retrieval of information from memory strengthens that memory and increases the interval before it will be forgotten, creating a pattern where memories that are reviewed just as they are about to be forgotten...
