Define spaced repetition.

• A. A method of cramming information
• B. A technique involving random review times
• C. A study technique using increasing intervals between reviews
• D. A strategy for immediate recall

Answer: (C)

Spaced repetition is a study technique that optimally uses increasing intervals between reviews to enhance memory retention and recall. This method is based on the idea that information is more likely to be retained long-term when it is reviewed at strategically spaced intervals rather than crammed in a short period.

As the learner becomes more familiar with the material, the gaps between study sessions can be lengthened. This approach takes advantage of the psychological spacing effect, which emphasizes that information is better remembered when exposure occurs over a longer duration and with time in between, rather than in close succession.

By using spaced repetition effectively, learners can reinforce their understanding and memory of the material, making it a powerful tool for studying and mastering complex subjects. This is distinct from techniques that might promote immediate recall without long-term retention or that lack a structured system for timing reviews.
