Ordering the three memory functions correctly gives:

1. Information has to get in before it can be held or brought back. 2. We get information into our brains through a process called encoding. 3. Once the information has been encoded, we have to somehow retain it, which is storage. 4. Retrieval, or getting the information out of memory and back into awareness, is the third function. 5. The order is fixed by what each function requires of the one before it. _Source: OpenStax Psychology 2e (CC BY 4.0), Ch 8 'Memory', sections 8.1-8.4_
