Concept information
Preferred term
power function
Definition
- A mathematical function that describes the evolution of forgetting over time, especially the fact that forgetting is rapid after learning and slows down as time passes. It takes the form Y = at⁻ᵇ in which y is the memory performance, t is the elapsed time, b is the forgetting rate and a is a scaling parameter.
