Which statement correctly describes spaced retrieval as a retrieval practice technique?

• A. Cramming
• B. Massed practice
• C. Spaced retrieval involves reviewing material at increasing intervals
• D. One-time review

Answer: (C)

Spaced retrieval is a retrieval practice approach where you recall information at increasing time intervals. This leverages the spacing effect, which makes long-term memory stronger when practice sessions are spread out rather than bunched together. In this method you actively try to retrieve what you’ve learned, and you progressively lengthen the gaps between attempts as your recall improves. This contrast with cramming, which packs study into a short period; with massed practice, reviews happen in quick succession with little to no spacing; and with a one-time review, there’s no ongoing retrieval to reinforce memory. So the statement that spaced retrieval involves reviewing material at increasing intervals accurately captures the technique.
