spacing effect
n.— «Wxams after the break are a better measure of true learning, rather than the memorization. Psychologists use the term “spacing effect” to explain why: The review of material increases long-term memory best when there is more time between the introduction and review of material. Therefore, it is actually better for the exams to be taken after break to increase that spacing.» —“Break allows time to re-learn the material” by Clair Aronson Sun Sentinel (Fort Lauderdale, Florida) Dec. 18, 2008.
