retention interval

The retention interval is the amount of time that passes between when information or a memory is learned and the moment it is tested or remembered later. It reflects how long information is stored in our memory before recall or forgetting occurs. For example, if you study for a test today and take it tomorrow, the retention interval is one day. Shorter intervals typically mean better recall, while longer intervals can lead to decreased memory accuracy or forgetting, depending on various factors like the importance of the information and how often it is reviewed.
