Spacing effect

The robust finding that the same total practice produces more durable learning when distributed across multiple sessions over time than when crammed into one (massed) session.

Defined in 3 GAGE programs, which carry 3 distinct definitions of it. The wording above is taught in AI Literacy & Professional Conduct.

How each discipline defines it

The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.

Foundations of Robotics and Physical AI

The empirical finding, documented since Ebbinghaus's 19th-century research and replicated across domains, that active recall at increasing time intervals produces substantially more durable retention than massed re-reading of the same material (Roediger and Karpicke, Psychological Science, 2006). Operational implementation: recall at two days, five days, and two weeks after initial study.

Engineering Judgment and Professional Formation

The finding, with roots in Ebbinghaus's nineteenth-century forgetting-curve research and confirmed at scale by Cepeda, Pashler, Vul, Wixted, and Rohrer's 2006 meta-analysis, that distributing study of the same material across multiple separated sessions produces stronger long-term retention than massing the same total study time into one session.

AI Literacy & Professional Conduct

The robust finding that the same total practice produces more durable learning when distributed across multiple sessions over time than when crammed into one (massed) session.
