This is where we hold information temporarily while actively using it. It has a limited capacity—traditionally thought to be about seven items—and lasts for roughly 20 to 30 seconds unless reinforced.

Psychologists typically divide memory retention into three distinct phases: What is Memory Retention?

The transition from short-term to long-term memory happens through . This process is influenced by several factors:

You cannot retain what you don’t notice. Focus is the gateway to storage. During sleep, the brain undergoes consolidation , a

Memory retention is the brain's ability to store, preserve, and retrieve information over time . It is not a single "filing cabinet" but a complex, multi-stage process that allows us to learn from the past and navigate the present. The Three Stages of Retention

This is the final stage, where information is stored semi-permanently. Long-term memory has an almost limitless capacity and can store data for years or even a lifetime. How Information Sticks Memory retention is the brain's ability to store,

Retention is rarely perfect. The "Forgetting Curve," a concept introduced by Hermann Ebbinghaus, suggests that we lose roughly 50% of new information within an hour if we don't actively review it. Forgetting usually occurs due to (new info clashing with old) or decay (neural traces weakening over time).
