What Is Memory?

Memory is the process that allows us to encode, store, and retrieve information so we can use past experience in the present. It is not a single mental “file cabinet,” but a set of interconnected systems that help us learn, recognize, recall, and make decisions.

In this lesson, students learn what memory is, why it matters, and why it is better understood as an active process than a perfect recording device. This foundation sets up later lessons on why forgetting happens and how memory can be improved.
