1. Revision 4Oct 4, 2026, 3:58 PMLiveAI-organised, reviewed

   Adds newer evidence: spaced repetition improved diagnostic accuracy and speed in a within-participant histopathology study, spacing effects appear to generalize in artificial and biological systems, but a motor-sequence study found no lasting learning advantage from spacing. Adds a behaviour-change study showing students often know effective strategies but don't use them, and that coaching raised spacing without exam gains.
