What is The spacing effect?
The spacing effect is the finding that we learn and remember better when study sessions are spread out over time, rather than crammed together. Reviewing material across days or weeks builds far stronger, longer-lasting memories than cramming.

Frequently asked questions
- What is the spacing effect?
- The finding that spreading learning over time produces stronger memory than massing it in one session.
- Why does spacing work better than cramming?
- Each spaced review re-strengthens the memory just as it starts to fade, deepening long-term retention.
- How do you use the spacing effect?
- Review material at increasing intervals — days, then weeks — instead of all at once, often via flashcards.
