Glossary:Stabilization curve

stabilization curve

shows the dependence of stabilization on retrievability.

The formula for the stabilization curve:

SInc=SIncMax*e-Gain*R

where:

• SInc - stabilization (aka stability increase) is the ratio of memory stability after and before the repetition
• SIncMax - maximum possible increase in memory stability. SIncMax depends on current stability and memory complexity (i.e. item difficulty). Maximum stabilization can be achieved at the verge of forgetting
• Gain - a constant that expresses the gain in stabilization with passing time (gain is a measure of the spacing effect)
• R - retrievability, i.e. the expected probability of recall at a given point in time. It is determined by the forgetting curve
