What is the term for the amount of time saved when relearning a task?

The term for the amount of time saved when relearning a task is known as a savings score. This concept is particularly relevant in the study of memory and learning, where it quantifies how much faster an individual can learn a task upon a second or subsequent attempt compared to the initial learning session. The savings score demonstrates that some memory of the task has persisted, even if the individual does not recall the task completely, highlighting the efficiency of memory retention and the potential for faster retrieval of learned information.

In contrast, the term "relearning" simply refers to the process of learning something again. It does not quantify the time or efficiency gained compared to the original learning experience. Long-term potentiation is a physiological process involving the strengthening of synapses based on recent patterns of activity, and while it relates to memory, it does not specifically address the time saved in relearning. The recency effect refers to the tendency to better remember items presented at the end of a list, which is a different concept concerning memory recall and does not pertain to the efficiency of relearning tasks.
