May 10 GUEST POST: Retrieval Strength Vs. Storage Strength
The retrieval strength of a given piece of information can be high or low, and can fluctuate back and forth between these values. Retrieval strength is measured by current performance (e.g., answering questions in class, on a test). Storage strength (SS)is a measure of whether information is deeply embedded or well learned (is it likely to be ...
