The Science Behind Spaced Repetition
Spaced repetition leverages the psychological spacing effect, where information is more effectively retained when exposure is spread over increasing intervals rather than massed practice.
🧠 How Memory Works
Initial Learning
Information enters short-term memory with rapid initial decay
First Review
Strengthens neural pathways, slows forgetting rate
Spaced Reviews
Each review at optimal intervals consolidates long-term memory

Optimal Spacing Intervals
⏰ The Goldilocks Principle
Reviews should occur just before you're about to forget - not too early (inefficient) or too late (requires re-learning).
After first exposure
If remembered correctly
Continued success
Long-term consolidation
Periodic reinforcement
⚡ Dynamic Adjustment
If you remember easily:
- • Increase next interval by 2-3x
- • Consider the item well-learned
- • Move to maintenance schedule
If you forget or struggle:
- • Reset to shorter intervals
- • Add contextual cues or mnemonics
- • Increase exposure frequency
