The process that moves information from short-term memory into long-term memory is:

1. Information in short-term memory fades quickly unless something is done with it. 2. Rehearsal moves information from short-term memory to long-term memory. 3. Repeating or working with the material is what keeps it available. 4. Retrieval works in the opposite direction, bringing stored material back. _Source: OpenStax Psychology 2e (CC BY 4.0), Ch 8 'Memory', sections 8.1-8.4_
