Which type of practice is most likely to lead to rapid forgetting?

Spaced practice distributes learning over time, allowing for intervals between study sessions. This method enhances retention and strengthens memory consolidation, leading to better long-term recall. Research consistently shows that spaced learning is more effective than massed practice in promoting durable memory.

Interleaving involves mixing different topics or types of problems during practice. This technique enhances learning by requiring the brain to continually adapt and retrieve varied information, which promotes deeper processing and retention. Rather than resulting in forgetting, interleaving typically improves memory performance over time.

Retrieval practice focuses on actively recalling information from memory, which reinforces learning and aids in retention. This approach has been shown to significantly enhance long-term memory compared to mere review and is unlikely to lead to rapid forgetting, as it strengthens the neural connections associated with the learned material.
