Which principle involves strategically spacing out study sessions over time to improve learning outcomes?

• A. Interleaving
• B. Spacing
• C. Retrieval Practice
• D. Feedback

Answer: (B)

Spacing, or spaced practice, is the idea of distributing study sessions across time rather than cramming. When you revisit material after a delay, you have to retrieve it from memory, which strengthens the memory traces and slows forgetting. Over time, this leads to better long-term retention and easier recall under tests. This emphasis on scheduling distinguishes it from interleaving (mixing different topics in one session), retrieval practice (actively recalling information), and feedback (information about correctness after you respond). So planning regular reviews across days or weeks is the approach that best matches this principle.
