===Atkinson–Shiffrin memory model===
According to the dual store memory model proposed in 1968 by [[Richard C. Atkinson]] and [[Richard Shiffrin]], memories can reside in the short-term "buffer" for a limited time while they are simultaneously strengthening their associations in LTM.<ref>{{Cite journal |last1=Malmberg |first1=Kenneth J. |last2=Raaijmakers |first2=Jeroen G.

The limit of items that can be held in the short-term memory is an average between four and seven, yet, with practice and new skills that number can be increased.<ref name="Goldstein, E. Bruce, 1941–2015"/> However, each time an item in short-term memory is rehearsed, it is strengthened in long-term memory. Similarly, the longer an item stays in short-term memory, the stronger its association becomes in long-term memory.<ref name="Atkinson 1968 89–195">{{cite book |pages=89–195| last1=Atkinson| first1=R.C.| last2=Shiffrin | first2=R.M.| year=1968| title=Chapter: Human memory: A proposed system and its control processes| volume=2| doi=10.1016/s0079-7421(08)60422-3| series=Psychology of Learning and Motivation| isbn=9780125433020| s2cid=22958289| url=https://escholarship.org/uc/item/2qq391s9}}</ref>
