Spaced Repetition
Space creates stronger memory.
Shrink Definition
Spaced repetition is the practice of reviewing information at increasing intervals over time to strengthen long-term memory. Rather than studying intensively once, spaced repetition repeatedly strengthens memory before forgetting becomes complete.
Plain language
Learning sticks better when it's revisited over time.
Shrink Insight
The brain values information it repeatedly encounters across time.
Why it matters
Spaced repetition improves: • language learning • medical education • board examinations • professional development • technical training • lifelong learning
Common misunderstanding
Studying longer isn't always better. Studying again later often is.
Shrink Perspective
Memory grows through timing as much as effort.
Shrink Reflection
What knowledge deserves to stay with you for years rather than days?
Shrink Journal
Identify one important topic. Create a review schedule for tomorrow, next week, next month, and three months from now.
Shrink Step
Instead of extending today's study session, schedule your next review.
Shrink Minute
Remember over time.
Shrink Takeaway
Spacing strengthens memory.
Medical boundary
This concept is educational and shouldn't be used to self-diagnose. It doesn't replace care from a licensed clinician. Symptoms, medication, and treatment decisions should be discussed with a qualified professional, and emergency symptoms require emergency care.
Evidence summary
Spaced repetition is one of the most robust findings in cognitive psychology. More than a century of research demonstrates that appropriately spaced review substantially improves long-term retention compared with massed practice.
