Why does spaced practice outperform massed practice?

Using the assigned readings, explain why spaced practice (distributing study over time) typically produces stronger long-term retention than massed practice (cramming). Ground your answer in at least two mechanisms discussed in the readings. ~180–250 words.

Chapter

Bjork & Bjork (2011) · p. 58

“Conditions of practice that slow acquisition and feel less fluent — spacing, interleaving, generation — often produce more durable long-term learning than conditions that feel easy in the moment.”

Bjork & Bjork (2011) · p. 61

“Re-encountering information after some forgetting has set in requires effortful retrieval, and the act of retrieval itself modifies the memory, making it more accessible next time.”

Review

Cepeda et al. (2006) · p. 359

“Across 317 experiments, the benefit of spaced over massed practice grew as the retention interval lengthened; for short tests, spacing effects were modest or absent.”

Cepeda et al. (2006) · p. 372

“Optimal gap length scales with the retention interval: roughly 10–20% of the interval between study and test.”

“Each study episode occurs in a slightly different internal and external context; spaced repetitions therefore associate the material with a broader set of retrieval cues.”
