Which term captures the strategy of presenting material across multiple days or times to improve retention?

• A. Storage
• B. Retrieval
• C. Spacing
• D. Interleaving

Answer: (C)

Spacing, also known as spaced practice, is the strategy of distributing study across multiple days or times. When you revisit material after a delay, you must retrieve it from memory, and this retrieval strengthens the memory trace. Each retrieval after a pause solidifies the knowledge, improves durability, and makes it easier to recall later, especially across different contexts. Spacing also reduces interference because you encounter the material in new contexts and with time to forget a bit, which makes the subsequent review more effortful and effective. Over time, expanding the intervals between reviews tends to yield better long-term retention than studying the same topic in one long block. This differs from storage, which is about encoding and maintaining information; retrieval, which is pulling information from memory; and interleaving, which mixes different topics during practice.
