Forgetting Curve (Ebbinghaus’s Curve of Retention)

Forgetting Curve (Hermann Ebbinghaus, 1890s) is visual representation that is purported to show how a memory weakens over time when it is not practiced or rehearsed. That weakening is typically characterized as an exponential decay (and often described in terms of half-life – i.e., the time required to reduce to half of the current strength).
